pulmonary embolism
What other systems can also be involved in respiratory disease and should therefore be considered for history taking during a respiratory history?
● Cardiac disease - pulmonary oedema -> angina, orthopnoea, paroxysmal nocturnal dyspnoea.
● Immunocompromised patients - HIV, Immunosuppression, and post-transplant surgery may indicate predisposition to atypical infections.

What is the protocol for introduction during a respiratory exam?
● Wash hands
● Introduction, identification and consent.
● General inspection of the bed area
● General observation of the bed area
What information can be ascertained from the general inspection of a patients bed area during a respiratory exam?
● Inhalers
● Nebuliser
● Oxygen mask
● Sputum pot
What information can be ascertained from the general inspection of a patient during a respiratory exam?
● Colour of the patient
● Breathing of the patient
● Comfort of the patient
● Purse lipped breathing -> COPD
● Nutritional state -> Obesity (obstructive sleep apnoea, pickwickian syndrome)
What are the four steps of a respiratory exam?
● Inspection
● Palpation
● Percussion
● Auscultation
What are some general observations of the hands during a respiratory exam?
● Colour
● Tar staining
● Skin changes
● Joint swelling or deformity
What would a colour change of the hands indicate during a respiratory examination?
● Cyanosis of the hands may suggest underlying hypoxia.
What would tar staining of the hands indicate during a respiratory examination?
● Caused by smoking, a significant risk factor for respiratory disease e.g. COPD and Lung cancer.
What would skin changes of the hands indicate during a respiratory exam?
● Bruising or thinning of the skin can be associated with long-term steroid use e.g. asthma, COPD, interstitial lung disease
What can joint swelling or deformity of the hands indicate during a respiratory exam?
● May be associated with rheumatoid arthritis which has many extra-articular manifestations that affect the respiratory system e.g. effusion and fibrosis.
What is finger clubbing?
● Finger clubbing involves uniform soft tissue swelling of the terminal phalanx of a digit with subsequent loss of the normal angle between the nail and the nail bed.
In which diseases would finger clubbing be present?
● Finger clubbing is associated with several underlying disease processes.
● Most likely to be due to lung cancer, interstitial lung disease and cystic fibrosis.
How would you assess finger clubbing during a respiratory exam?
● Ask the patient to put their nails of their index fingers back to back.
● Healthy individual = small diamond shaped window called Schamroth’s window can be seen
● When clubbing develops this window is lost
How would you assess a fine tremor during a respiratory exam?
● Ask the patient to hold out their hands in an outstretched position and observe for a fine tremor which is typically associated with beta-2-agonist use (e.g. salbutamol)
What is asterixis?
● A type of negative myoclonus characterised by irregular lapses of posture causing a flapping motion of the hands.
What are the most likely causes of asterixis?
● Most likely - underlying CO2 retention in conditions that cause type 2 respiratory failure.
● Other causes - uraemia and hepatic encephalopathy.
How would you assess for asterixis during a respiratory exam?
● Ask patients to outstretch their hands and ask them to cock their hands back at the wrist joint and hold the position for 30 seconds.
● Observe during this time period.
Overall, what changes can be observed from the hands during a respiratory exam?
● Colour of patient
● Tar staining
● Skin changes
● Joint swelling / deformity
● Finger clubbing
● Fine tremor
●Asterixis
What actions would you perform during palpation of a patient during a respiratory exam?
● Temperature check
● Heart rate
● Respiratory rate
How would you assess the temperature of a patient during a respiratory exam?
● Place the dorsal aspect of the hand upon the patient.
● Healthy patient should be symmetrically warm
What would cool hands indicate during a respiratory exam?
● May suggest poor peripheral circulation.
What would excessively warm hands indicate during a respiratory examination?
● Can be associated with CO2 retention
How would you assess the patients heart rate during a respiratory exam?
● Palpate the patients radial pulse, located on the radial side of the wrist
● The tips of your index and middle finger aligned longitudinally over the course of the artery.
● Once you have located the pulse, assess the rate and rhythm.
How would you calculate the heart rate of a patient during a respiratory exam?
● Can either measure over 15, 30 or 60 seconds and scaling up respectively.
● The shorter the interval used the more inaccurate the result.
● For irregular rhythms you should use the full 60 seconds.
What would a bounding pulse indicate during a respiratory exam?
● Can be associated with underlying CO2 retention (e.g. type 2 respiratory failure).
What would pulsus paradoxus indicate during a respiratory exam?
● This is a late sign of cardiac tamponade, severe acute asthma and severe exacerbations of COPD (unlikely to come up during OCSE station)
What is pulsus paradoxus?
● Pulse wave volume decreases significantly during the inspiratory phase.
How would you assess respiratory rate during a respiratory exam?
● While still palpating the patients radial pulse, assess the respiratory rate.
● Do not make the patient aware you are doing this as it can alter consciousness of breathing in the patient.
What would differences in the respiratory rate indicate during a respiratory exam?
● Asymmetries in the expiratory and inspiratory phases of respiration (e.g. the expiratory phase is often prolonged in asthma exacerbations and in patients with COPD).
How would you calculate respiratory rate during a respiratory exam?
● Assess the patient’s respiratory rate for 60 seconds to calculate the number of breaths per minute.
What would a healthy respiratory rate be in adults?
● Should be between 12-20 breaths per minute.
What is bradypnoea and what would this potentially indicate?
● A respiratory rate of less than 12 breaths per minute.
● Opiate overdose
What is tachypnoea and what would this potentially indicate?
● A respiratory rate of more than 20 breaths per minute.
● Acute asthma
What does jugular venous pressure indicate during a respiratory exam?
● Provides an indirect measure of central venous pressure.
Why can the JVP provide an indirect measurement of the central venous pressure?
● Internal jugular vein connects to the right atrium without any intervening valves, resulting in a continuous column of blood.
● The changes in the right atrial pressure are reflected in the internal jugular vein
