Appendicectomy Preoperative Intraoperative & Postoperative Nursing Care

Spread the love

Abdominal pain is most commonly caused by appendicitis, which may lead to the most frequently performed surgical procedure – Appendicectomy. While this can happen at any age, it is a common occurrence in the young.

The appendix is a closed ended narrow tube measuring about 6mm in diameter and 7cm long. It is found in the right iliac region of the abdomen, beneath the ileocecal valve (McBurney’s point).

Management of Appendicitis:

  • PROMPT TREATMENT: prevents morbidity and mortality
  • PREOPERATIVE CARE: supporting patient and management of symptoms
  • INTRAOPERATIVE CARE: appendicectomy
  • POSTOPERATIVE CARE: preventing complications and providing reassurance and comfort

Appendicectomy & Appendectomy = same procedure, different terminology.

Appendicectomy Preoperative Care

Apart from following the normal preoperative care techniques, an appendicectomy requires the following as well:

  • NIL BY MOUTH – no foods, drinks or oral medications should be taken as soon as decision is taken for an appendicectomy
  • IV FLUIDS ADMINISTRATION – dehydration is probable due to vomiting being a normal symptom of appendicitis
  • VITAL SIGNS MONITORING – a fever over 38.5°C may be due to the rupture of the appendix
  • NO ANALGESIA – pain needs to be monitored, not subsided, as it indicates what is happening with the appendix; regular analgesia should be administered to help the patient feel more comfortable prior to appendicectomy
  • NO HEAT – increases the risk of perforation and rupture of the appendix
  • NO LAXATIVES – induced peristalsis increases the risk of perforation and rupture of the appendix
  • VOIDING – patient should be encouraged to void if undergoing surgery for which no bowel preparation is recommended such as in appendicectomy, as avoiding incontinence during the operation leads to a lesser chance of infection

Intraoperative Negligence:

If a foreign body such as a swab is left accidentally in the patient during surgery, the patient may experience symptoms such as sepsis, localised discomfort, skin protrusion, nausea and constipation. If this goes unnoticed for a longer time, more serious complications may arise, such as abscess formation, fistulas, bowel perforation, and extreme localised pain.

To avoid such complications:

  1. count instruments and swabs during setup prior to surgery commencement
  2. count again before surgery begins
  3. count again as closure begins
  4. count again during skin closure

Pay special attention in the case of obese patients.

Appendicectomy: Open Method

Preferred method of surgery in the case of:

  • perforated appendicitis
  • peritonitis
  • history of abdominal surgery
  • paediatric patients
  • appendicular abscess

An open method appendicectomy provides good exposure, is easier to perform and straightforward. However, pelvic structures cannot be seen well, it takes longer for the patient to recover post-operation, it increases the risk of hernias and adhesions due to the weakening of the abdomen tissue by the manipulation of the bowels.

Appendicectomy: Laparoscopy

Preferred method of surgery in the case of:

  • lower complication rate
  • helps diagnose other conditions especially in women
  • preferred method for women, obese patients and athletes
  • provides better cosmetic results
  • causes less postoperative pain
  • patient can return to normal activity early

However, a laparoscopic appendicectomy takes longer to be performed, and comes at a much higher cost. Not all surgeons use this method as it requires experience. Carbon Dioxide is used to inflate the abdomen to allow surgeons to work, which may cause shoulder pain. Additionally, lack of mobilisation may lead to a needed open procedure nonetheless.

Appendicectomy Postoperative Care

If patient experiences peritonitis, antibiotics are administered IV to treat infection.

Peritonitis may develop after an appendicitis. This happens due to bacteria spread which may go unnoticed during appendicitis.

A drain may be inserted during surgery. Monitor drainage, which should decrease in time…if not, patient could be experiencing a haemorrhage.

Patient should be encouraged to mobilise as soon as possible to prevent the formation of emboli. In addition, anti-coagulants may be administered subcutaneously post-operatively, and anti-embolism stockings should be worn.

Patient may be started on food slowly only after bowel sounds can be heard, which proves good function of bowels.

Appendicectomy  peritonitis
Retrieved from https://www.pinterest.es/pin/68117013089501100/ on 9th March 2021

The patient is discharged once no fever is recorded and bowels are functioning well. Drain is removed once infection is fully resolved. Stitches are removed 7-10 days post-surgery; this can be done at a health centre. A histopathology report is later given during an outpatient visit.

No need of special diets, exercise or other lifestyle factors are required post appendicectomy.

Perioperative Nursing – Preoperative Intraoperative & Postoperative Care

Spread the love

Perioperative Nursing Care

Perioperative nursing care includes:

  1. Preoperative Phase: when the patient is prepared and transferred to the theatre prior to undergoing surgery;
  2. Intraoperative Phase: during surgery and in the recovery room;
  3. Postoperative Phase: from the recovery room to the ward and until discharge, ending completely after being reviewed at the Outpatients Department.

Preoperative Nursing Care

Surgery may be required for the following reasons:

  • when further exploration is required to reach a proper diagnosis
  • as a preventative measure such as for the prevention of cancer spread
  • for treatment purposes
  • for palliative purposes such as the removal of tumors
  • for cosmetic and reconstructive purposes

PLANNED SURGERY: not an urgent requirement. It is usually scheduled weeks, months and at times years ahead.

EMERGENCY SURGERY: urgent requirement, usually performed for lifesaving purposes, as well as to stop bleeding (eg. internal bleeding) or to preserve an organ or limb (eg. in compound/open fractures where bones are protruding from the skin.

Types of surgeries:

  • Minor Surgery (eg. cyst removal or suturing)
  • Minimally Invasive (eg. infiltrations, injections)
  • Keyhole Surgery (eg. laparoscopy)
  • Major Surgery (eg. hysterectomy)

Preoperative Considerations include:

MEDICAL HISTORY: this should include information about the patient’s current health condition, known allergies, current medications list, drug abuse, past surgeries experience if any, and the identification of risk factors especially in the case of past problems with anesthesia.

PSYCHOSOCIAL STATE: evaluating the patient’s situation in relation to psychological and social wellbeing can help identify possible barriers to the recovery phase post-surgery. Reassurance can help alleviate fear, anxiety and stress pre-surgery. If needed, a patient can be referred to a social worker for additional support eg. if patient has left children behind at home, alleviating fears and concerns about their care helps reduce the person’s anxiety and stress.

EDUCATION: the patient should be provided with clear and understandable explanation with regards to what the surgery entails as well as what perioperative nursing care may be required, both verbally and in writing. The patient should also be advised about postoperative monitoring equipment which may be needed, as well as possible tubes, drains and other related equipment use in perioperative nursing care. Pain management should also be discussed with the patient in advance.

INVESTIGATION: blood tests (including CBC, urea, electrolytes and creatinine, INR or APTT and glucose), X-Rays, MRIs and CT Scans, ECG and a crossmatch (a.k.a. X-Match). Wherever possible, preoperative care should include the treatment of any existing infections, monitoring and if possible stabilising existing chronic diseases such as hypertension and diabetes, dietary deficiency and fluid and electrolyte imbalance correction, and if need be, weightloss in obese patients.

RISK FACTORS: can impact surgery success and recovery. Risk factors include age, malnutrition or obesity, pregnancy, as well as infection, diabetes, CVD, renal disease, malignancy, pulmonary disease, hepatic disease, immobility and hypovolaemia (excessive bleeding).

INFORMED CONSENT: patient signature should be acquired by the consultant prior to surgery. The nurse should make sure that information about the procedure or surgery is provided and any questions are addressed so the patient is able to give informed consent; the nurse should also make sure that informed consent has been acquired.

Preoperative Nursing Care:

  • address anxiety through communication and if needed adding music therapy, deep breathing, etc; address any body image concerns in relation to the surgery
  • nail polish should be remove so SP02 can be monitored correctly
  • bathing (4% chlorhexidine solution if patient is MRSA colonised; 2% chlorhexidine solution if undergoing a major operation; soap and water if patient is undergoing minor operation
  • shaving should be done using hair clipper so as to avoid skin abrasions, thus minimising the risk of developing a Surgical Site Infection; shaving should be done closest to the surgery time so as to avoid having enough time for bacteria from cultivating within any possible skin abrasions
  • make sure surgery site has been pre-marked by surgeon or consultant prior to being transferred to the theatre
  • keep patient warm using blankets if needed, as this will help prevent development of SSIs
  • surgical site observation
  • monitoring and documentation of patient vital signs
  • fasting and/or intake restrictions
  • possible need of medication restriction eg. drugs affecting coagulation
  • checking for dentures and loose teeth
  • bowel preparation (if needed)
  • tubes eg. nasogastric tube or urinary catheter (although these may be inserted during surgery)
  • administration of recommended pre-surgery medication eg. prophylactic antibiotics
  • completing pre-op checklist
  • if a patient with diabetes is scheduled for surgery, he should be started on the diabetic protocol since being NBM makes him prone to hypoglycaemia
  • in the case of an amputation, make sure that the leg to be amputated has been marked by the physician
  • if patient has left children behind at home, talk and empathise with the patient to help alleviate any concerns; if need be, refer to a social worker so as to ensure help will be provided during this time and during post-op period
  • if spiritual concerns are involved eg. existential problems, referring to a spiritual advisor may also help
  • if patient seems to be experiencing psychological issues in relation to surgery, referring to a psychologist may help
  • if patient is eager to know, explain the whole procedure eg. where patient is to be transferred to, what to expect right after surgery, recovery area, post-op pain management, etc.

NOTE: If patient is on Steroids pre-op for inflammation, consider that steroid side-effects include hyperglycaemia (attn. if patient is diabetic), affecting the immune system (attn. if patient is immunocompromised), and affecting the peripheral nervous system (attn. if patient has been or is being amputated or has existing issues with his arms and legs).

Transferring patient from ward to the theatre:

  1. Check patient ID
  2. Check allergy bracelet
  3. Explain procedure
  4. Ensure patient safety
  5. Provide accurate handover to the theatre nurse

Postoperative Nursing Care

This period starts right after surgeons finish the operation (an anesthetist and a theatre nurse stays with the patient after surgeon leaves), up until the 1st review after discharge as an outpatient.

Patient Assessment Right After Surgery

PULSE: monitor pulse volume and regularity

SKIN: check for any signs of cyanosis and monitor SPO2

CONSCIOUSNESS: is the patient conscious or semi-conscious? Prior to transfer to ward, patient should be fully conscious

AIRWAY: assess respiratory rate and depth

Patient Assessment In Recovery Room

  • understand and follow up on anesthetist and surgeon’s instructions
  • pain management: PCA pump if provided; prescribed medication, including PRN medication if needed
  • monitor vital signs and level of consciousness
  • assess level of pain, at rest and when ambulating; if noticing increased pain during ambulation, prophylactic pain medication may be administered pre-ambulation so as to reduce the pain and increase effectiveness of ambulation
  • monitor surgical site for bleeding and signs of infection
  • monitor input and output for urinary retention and/or for renal function indications
  • assess for signs of complications post-surgery, especially in relation to cardiovascular and pulmonary related comorbidities eg. Pneumonia (see pneumonia prevention section in link for preventative measures)
  • monitor for fluid imbalance (possible loss of fluid during surgery)
  • report any changes in patient condition and document changes
  • keep NBM for a couple of hours due to relaxed reflexes as an effect of anaesthesia
  • for diabetic patients, keep monitoring for hypoglycaemia especially whilst NBM

Patient Transfer From Theatre to Ward

Patient needs to be fully conscious and stabilised before being transferred to the ward. Monitor for any neurological impairment such as lack of movement of limbs, IV fluids and drip rate, drains, as well as same monitoring undergone in the recovery room.

Post-Surgery Investigations

  • check CBC (haemoglobin due to bleeding during and post-surgery, white cells, platelets, sodium, potassium, urea [to monitor for kidney function], creatinine and glucose [in diabetic patients, glucose status should be checked routinely])
  • X-Rays
  • MRI
  • CT Scan

Patient Care In The Ward

  • Observe IV Infusion,IV Pumps and Cannula Site
  • Assess For Nausea: patient may be administered an antiemetic drug to prevent nausea and vomiting
  • Personal Hygiene: bathing and mouth care
  • Patient Repositioning: to avoid pressure sores
  • Monitor for Confusion and Delirium
  • In case of Altered Level of Consciousness post-op, provide safety eg. side rails pulled up, personal items at reach etc
  • Monitor for Drug Allergy Symptoms
  • Patient Mobilisation: earliest possible ambulation if not contraindicated as it helps prevent complications in relation to respiration, deep vein thrombosis and pulmonary oedema; assist during ambulation
  • Encourage Deep Breathing and Coughing Exercises
  • Promote Exercise and Movement
  • Ensure Adequate Fluid Intake: start with encouraging small sips if not contraindicated
  • Wound Care: assess for infection and change dressings as required
  • Tracheostomy Care: including suctioning if present
  • Monitor for Urinary Retention: can cause restlessness, bladder distension, suprapubic discomfort and confusion; insert catheter to eliminate retention and confusion
  • If Increased Wound Bleeding is noticed, DO NOT remove the existing bandages, but apply extra pressure with another bandage on top and inform physician

Asthma Pathophysiology, Diagnosis, Medical Management & Nursing Care

Spread the love

Asthma pathophysiology involves chronic inflammation of the airways that causes bronchoconstriction (constriction/narrowing of the smooth muscle of the bronchioles), leading to airway hyperresponsiveness (narrowing bronchioles in response to allergens), excessive mucus production and retention (cilia become paralysed in airway during chronic inflammation), and airway oedema. Asthmatic patients with airway inflammation, which is reversible, tend to experience symptom-free periods as well as acute asthma exacerbations.

asthma pathophysiology
Accessed from https://vector.childrenshospital.org/2013/12/the-obesity-asthma-connection-a-link-in-the-innate-immune-system/ on 3rd March 2021

Causes of asthma include allergies, exposure to airway allergens and air pollutants, exercise, stress, and medication such as NSAIDS (Ibuprofen, Voltaren etc.) and non-selective Type 2 Beta Blockers.

Asthma Signs and Symptoms:

  • Frequently presents at night or early morning
  • Dyspnoea
  • Wheezing (mostly on expiration…if present also at inhalation, patient condition is worse)
  • Cough with or without sputum
  • Central cyanosis (eg. blue lips)
  • Sweating
  • Tachycardia
  • Widened pulse pressure (a significant difference between the systolic and diastolic BP)
  • Other comorbidities such as GERD, COPD or respiratory tract infections increase risk for asthma

Asthma Complications:

  • Status asthmaticus (life threatening severe continuous reaction in which asthma exacerbation is completely unresponsive to bronchodilator treatment)
  • Pneumonia (infection originating from microorganisms that find their way to the lungs that inflames the alveoli in one or both lungs, causing accumulation of mucus, leading to cough with sputum, fever, chills and dyspnoea)
  • Respiratory failure (indicated by a decrease in BP, respiratory rate and heart rate)

Asthma Diagnosis Factors:

  • Family history of asthma
  • Reversibility (characteristic that differentiates asthma from other respiratory diseases)
  • Spirometry
  • Peak Expiratory Flow Rate (PEFR)
  • Respiratory acidosis is a very common acid base disturbance in acute severe asthma. Its early recognition and treatment is vital for the final outcome, as it can lead to respiratory failure and arrest if prolonged.

Asthma Pharmacological Therapy

QUICK RELIEF

  • short-acting beta 2 adrenergic agonists – bronchodilators eg. Salbutamol (Ventolin) that relieve bronchospasm by relaxing the smooth muscle leading to a decrease in bronchoconstriction as well as decrease excessive mucus (side effects include tachycardia, palpitations and nausea).
  • anticholinergic drugs – bronchodilators that can be used in combination with short-acting beta 2 adrenergic agonists eg. Ipratropium (Atrovent). Anticholergic drugs also decrease mucus secretions (side effect: dry mouth)
  • corticosteroids – eg. Prednisolone suppress inflammation leading to a reduction in hyperresponsiveness as well as a decrease in mucus production (side effect: hyperglycaemia).

LONG TERM MEDICATION

  • inhaled corticosteroids eg. Budesonide (Pulmicort) – administered as prophylaxis (as prevention) of acute asthma exacerbation
  • long-acting beta 2 adrenergic agonists eg. Tiotropium
  • Methylxanthines eg. Theophylline (prevent and treat wheezing, tachypnoea, and chest tightness)

Additional Interventions

  • In an emergency situation, quick administration of bronchodilators is recommended to relieve bronchospasms and systemic corticosteriods to reduce the inflammatory response.
  • Administration of IV fluids can help replace loss of fluid if patient is sweating profusely
  • Encouraging deep breathing and promoting a calm environment
  • Administer O2 if patient has a low SPO2
  • Encourage patient to sit down straight or slightly leaned forward to promote lung expansion
  • Teach pursed-lip breathing to promote an increase in lung ventilation

Monitoring an Asthmatic Patient Post-Treatment

  • Monitor SPO2
  • Monitor vital signs (heart rate, respiratory rate, temperature, blood pressure)
  • Auscultate for possible wheezing on inspiration or expiration and no use of accessory muscles whilst breathing
  • Perform PEFR to compare reading with the one taken prior to treatment
  • Monitor ABGs-PaO2 (arterial blood gases)
  • Monitor for anxiety level
  • Monitor for conversational dyspnoea

Hernia Repair – Hernia Locations, Types, Risk Factors, Symptoms & Surgery

Spread the love

A hernia occurs when an internal body part such as the small intestine pushes through weak muscle or surrounding tissue. Hernia repair is ideally performed so as to avoid complications.

REDUCIBLE HERNIA: intestines push through muscle or tissue but can still be pushed back in.

IRREDUCIBLE / INCARCERATED HERNIA: intestines push through muscle or tissue and cannot be pushed back into their original position.

STRANGULATED HERNIA: intestines push through muscle or tissue, become stuck and result in impaired blood supply, causing it to become necrotic. This requires an emergency procedure where the intestines require to be resected before the hernia is repaired.

Inguinal Hernia

An inguinal hernia is the most common type of hernia, mostly presenting in men due to the testicle descent at birth. It is located in the lower abdomen above the leg crease or close to the pubic area. Inguinal hernias are most common with ageing since the abdominal muscles become weaker with age.

In the case of girls, ovarian herniation of the canal of Nuck, which can occur at any age, is most common in childhood. Early diagnosis is vital since incarceration of the ovary can lead to ovarian necrosis.

INDIRECT INGUINAL HERNIA: a natural defect known as the ‘internal inguinal ring’ which is caused by testicles not descending before birth does not seal properly, and eventually develops into a hernia. This usually reaches the scrotum. It is very common in children.

DIRECT INGUINAL HERNIA: acquired by continuous exertion on the muscles. Presents as a forward protrusion and is found in adults.

Hernia Risk Factors

WEAKENED TISSUE: caused by ageing, surgical wounds, smoking, steroids, immunosuppresive drugs and collagen disorders.

EXERTED TISSUE: caused by heavy lifting, coughing, constipation, pregnancy, muscle strain.

Hernia Signs and Symptoms

  • swelling which may or may not be painless which may worsen when standing or straining, and improve when lying down.
  • burning sensation in the bulging area
  • weakness or pressure in the groin

Immediate action should be taken if an inguinal hernia causes pain as well as nausea and vomiting, or swelling that feels firm and tender.

Hernia Repair – Surgical Approaches

HERNIOTOMY: removal of the hernia sac.

HERNIORRHAPHY: removal of the hernia sac AND inguinal canal posterior wall repair. Repair is performed using the patient’s own tissue, and sutures cause tension on both sides to keep it closed. Unfortunately this conventional method of hernia repair can cause pain and discomfort, and has an unfavourable recurrence rate.

HERNIOPLASTY a.k.a. Lichtenstein Repair: removal of the hernia sac AND inguinal canal posterior wall repair with a synthetic mesh. This is one of the most commonly used methods of hernia repair that poses no tension, and in which the mesh is sutured over the defect. The mesh is made out of polypropylene. It is thin, flexible and lightweight, and helps reduce the risk of pain and foreign body sensation, acting as a base for new tissue growth that eventually incorporates it into the area.

Laparoscopic Hernia Repair

Laparoscopic hernia repair is especially indicated in the case of bilateral inguinal hernia or when diagnosis is not clear enough. This type of hernia repair is free of tension and is completed with the use of a mesh. CO2 is used to inflate the abdominal cavity to allow easy access for surgery. Laparoscopic hernia repair allows the patient to return to normal in less time than when an open surgery is performed.

Perioperative Nursing Care

Preoperative Care:

  • Assess pulmonary risk (if patient has a cold, coughing may exacerbate pain post-surgery).
  • Assess psychosocial patient needs including fear of anesthesia, fear of pain, fear of disruption of normal daily life.
  • Make sure patient is not given a gastrointestinal cleanser (laxative) in the case of an obstructed hernia.
  • Assure patient that pain relief will be given post-surgery as required. This may help alleviate any pain-management related worry.
  • Talk to the patient about what to expect to see post-surgery, eg. incision location and size, closure type, dressings, drains, tubes (including a NG tube, oxygen, IV and drains so the patient will feel prepared.
  • Monitor normal state of health, posture and other physical factors of the patient so as to be able to notice any important differences post-surgery.
  • Removal of hair is done with electric clippers and not blades, so as to minimise incisions (more infections risk).
  • Patient should fast for 6 hours from food or milk and 2 hours for clear fluid.
  • Sedatives may be administered to help reduce anxiety associated with surgery.

Intraoperative Care:

  • Correct positioning of patient on surgical table prior to surgery ensures patient comfort.
  • Avoid friction burns, shearing and damage to soft tissue of the patient.
  • Apply preventative measures against deep vein thrombosis by administrating Low Molecular Weight Heparin, using intermittent pneumatic compression devices and graduated compression stockings.
  • Use forced air warming blankets, warm IV fluids, irrigation and skin preparation fluids to prevent inadvertent hypothermia.
  • All swabs, instruments, needles and other surgical tools need to be accounted for and documented.
WHO surgical safety checklist
Accessed from https://www.who.int/patientsafety/topics/safe-surgery/checklist/en/ on 2nd March 2021

Postoperative Care:

  • Airway must be patent and clear, not with blood-tinged mucus.
  • Assist in supine or on the side to increase ventilation.
  • Monitor SP02.
  • Ensure bilateral even movement of the chest.
  • Respiratory changes may be a sign of respiratory or cardiac arrest.
  • Inspect wounds and drains for signs of haemorrhage.

Postoperative Complications:

Infection indicators include fever, erythema (superficial reddening of the skin), increased exudate and/or change in its colour, malodour, localised heat and/or pain, delayed healing. A well-balanced diet high in Vitamin C and protein may help reduce wound infection and quicker healing.

Fluid deficiency may lead to hypovolaemia (low blood volume) and hypotension (low blood pressure). Monitor blood pressure and pulse, intake and output, and note urine colour and concentration. Inspect mucous membranes, skin turgor (pinching up a small portion of skin and assessing whether it remains raised or not after letting go), and capillary refill (monitors amount of blood flow to the tissue).

Anatomy of the Respiratory System

Spread the love

When looking into the anatomy of the respiratory system, one needs to take a look at all the components involved in breathing. Through respiration, lungs experience ventilation (breathing), an exchange of gases happens between air and blood and between blood and cells, which cause oxygen perfusion throughout the whole body on a cellular level.

Respiratory System Functions:

  • provides the body with an oxygen supply
  • eliminates carbon dioxide
  • allows gas exchange
  • provides a path to and from the alveoli
  • provides a sense of smell through the olfactory system
  • acts as a humidifier by warming incoming air
  • maintains a balanced pH in the body
  • allows expulsion of abdominal content (such as during childbirth)

The respiratory system can be divided into the following sub-categories:

Upper Respiratory Tract:

Accessed from https://www.physio-pedia.com/Upper_respiratory_airways on 23rd February 2021
  • Nose: includes nostrils (nares), guard hairs (vibrissae, which help prevent insects and large particles from entering the nose), posterior nasal apertures (choanae), nasal cavity, nasal septum (composed of bone and cartilage), nasal fossae, nasal conchae, hard palate, soft palate, paranasal sinuses (which help decrease weight of skull due to its air content), goblet cells, respiratory epithelium of ciliated pseudostratified columnar type, and olfactory epithelium; functions include warming, humidifying and cleansing the inhaled air, providing a sense of smell, and helping in voice amplification.
  • Pharynx: a muscular structure about 5 inches long that acts as a common passageway for food and air consisting of the nasopharynx (lined with pseudostratified columnar epithelium), oropharynx and laryngopharynx (both lined with stratified squamous epithelium, making it a hard surface to be able to tolerate abrasion caused by the swallowing of food); includes an auditory tube, pharyngeal tonsil, palatine tonsils and lingual tonsils (tonsils help combat infection).
  • Larynx: plays an important role in speech through the vocal cords; comprises of 9 rigid hyaline cartilages with a flap of elastic cartilage known as the epiglottis that helps lead air and food into their appropriate pathways.
Accessed from https://sen842cova.blogspot.com/2015/08/pharynx-and-larynx-anatomy.html on 23rd February 2021

Lower Respiratory Tract:

Assessed from https://www.therespiratorysystem.com/category/lower-respiratory-tract/ on 23rd February 2021
  • Trachea: contains c-shaped hyaline cartilage rings that help support it (open parts of ‘c’ face the oesophagus to allow expansion whilst swallowing; lined with ciliated pseudostratified columnar epithelium with a lot of goblet cells that cause mucus production; mucus traps any debris, pushing it upwards through the mucociliary escalator towards the pharynx to be swallowed.
  • Bronchi: formed by the division of the trachea, just beneath the carina; supported by hyaline cartilage with a smooth muscle layered wall. These are further divided into secondary bronchi, one for every lobe within the lungs.
  • Bronchioles: the smallest of all bronchi, which end up with alveolar sacs; do not contain cartilage but are supported by smooth muscle, making them able to dilate or contract to cause bronchodilation or bronchoconstriction.
  • Alveoli: comprised of a single thin layer of squamous alveolar cells that facilitate gas exchange; contain alveolar macrophages (white blood cells) that engulf any bacteria or other debris; great alveolar cells produce a lipid molecule ‘surfactant‘ which coats the alveolar surfaces, preventing the alveoli walls from sticking together, thus allowing them to inflate easily during inhalation; air that enters the alveoli becomes available for gas exchange.
  • Lungs: found within the thoracic cavity; the stroma, which is made of elastic connective tissue, allows the lungs to recoil passively during exhalation; contain the visceral pleura (which ‘hugs’ the lungs), the parietal pleura (the outer layer), both encasing the pleural cavity which contains fluid that helps reduce friction between the lungs and the ribcage while they expand and contract); the two lungs are separated by the mediastinum which is the space found between the two lungs containing the heart, oesophagus and the major blood vessels. The right lung has 2 fissures, forming the superior lobe, middle lobe and inferior lobe. The left lung has 1 fissure, forming the superior lobe and the inferior lobe. The left lung also has the ‘cardiac notch‘, which is the area that houses the heart.

THE CONDUCTING ZONE forms a continuous passageway for air to move in and out of the lungs:

Nose > Pharynx > Larynx > Trachea > Bronchi > Bronchioles > Terminal Bronchioles

THE RESPIRATORY ZONE forms a passageway in which air is exchanged:

Respiratory bronchioles > Alveolar ducts > Alveolar sac

The respiratory membrane consists of squamous alveolar cell, squamous endothelial cell that lines the capillary, and a shared thin basement membrane, all of which help facilitate gas exchange.
