69
How would you assess the tracheal position during a respiratory exam?
1. Ensure patient’s neck musculature is relaxed by asking them to position their chin slightly downwards. 2. Dip your index finger into the thorax beside the trachea. 3. Gently apply side pressure to locate the border of the trachea. 4. Compare this space to the other side of the trachea using the same process. 5. A difference in the amount of space between the sides suggests the presence of tracheal deviation.
70
What should you do before you assess the tracheal position during a respiratory exam?

● Lobular collapse ● Pneumonectomy
73
What is the cricosternal distance?
● The distance between the inferior border of the cricoid cartilage and the suprasternal notch.
74
How would you assess the cricosternal distance during a respiratory exam?
1. Measure the distance between the suprasternal notch and cricoid cartilage using your fingers. 2. In healthy individuals, the distance should be 3-4 fingers.
75
What is special about the finger measurement when measuring the cricosternal distance?
● Cricosternal distance is actually based on the size of the patient’s fingers so if their fingers are significantly different in size from your own, it may be worth using their fingers for the assessment.
76
What would be a pathological finding when measuring the cricosternal distance and what would the indication be, during a respiratory exam?
● A distance of fewer than 3 fingers suggests underlying lung hyperinflation (e.g. asthma, COPD).
77
What are the steps involved in palpation of the chest during a respiratory exam?
● Palpate the apex beat. ● Assess chest expansion
78
How would you palpate the apex beat during a respiratory exam?
1. Palpate the apex beat with your fingers placed horizontally across the chest. 2. In healthy individuals, it is typically located in the 5th intercostal space in the midclavicular line.
79
What would a displaced apex beat be suggestive of during a respiratry exam?
● Right ventricular hypertrophy e.g. pulmonary hypertension, COPD, interstitial lung disease ● Large pleural effusion ● Tension pneumothorax
80
How would you assess chest expansion during a respiratory exam?
1. Place your hands on the patient’s chest, inferior to the nipples. 2. Wrap your fingers around either side of the chest. 3. Bring your thumbs together in the midline, so that they touch. 4. Ask the patient to take a deep breath in. 5. Observe the movement of your thumbs (in healthy individuals they should move symmetrically upwards/outwards during inspiration and symmetrically downwards/inwards during expiration ). 6. Reduced movement of one of your thumbs indicates reduced chest expansion on that side.
81
What pathology would be indicated for symmetrically reduced chest expansion during a respiratory exam?
● Pulmonary fibrosis reduces lung elasticity, restricting overall chest expansion.
82
What pathology would be indicated for asymmetrically reduced chest expansion during a respiratory exam?
● Pneumothorax, pneumonia and pleural effusion would all cause ipsilateral reduced chest expansion.
83
What is percussion of the chest used for during a respiratory exam?

84
Describe correct technique for chest percussion during a respiratory exam?
1. Place your non-dominant hand on the patient’s chest wall. 2. Position your middle finger over the area you want to percuss, firmly pressed against the chest wall. 3. With your dominant hand’s middle finger, strike the middle phalanx of your non-dominant hand’s middle finger using a swinging movement of the wrist. 4. The striking finger should be removed quickly, otherwise, you may muffle the resulting percussion note.
85
What areas should be percussed during a respiratory exam?
● Supraclavicular region: lung apices ● Infraclavicular region ● Chest wall: percuss over 3-4 locations bilaterally ● Axilla
86

90
What would a hyper-resonant percussion note indicate during a respiratory exam?
● The opposite of dullness, suggestive of decreased tissue density e.g. pneumothorax
91
Describe the correct technique for auscultation of the chest during a respiratory exam?
1. Ask the patient to relax and breathe deeply in and out through their mouth (prolonged deep breathing should, however, be avoided). 2. Position the diaphragm of the stethoscope over each of the relevant locations on the chest wall to ensure all lung regions have been assessed and listen to the breathing sounds during inspiration and expiration. Assess the quality and volume of breath sounds and note any added sounds. 3. Auscultate each side of the chest at each location to allow for direct comparison and increased sensitivity at detecting local abnormalities.
92
What are vesicular breath sounds?
● Normal quality breath sounds in healthy individuals.
93
What are bronchial breath sounds and what would it indicate during a respiratory exam?
● Harsh-sounding (similar to auscultating over the trachea), inspiration and expiration are equal and there is a pause between. ● This type of breath sound is associated with consolidation.
94
What would quiet breath sounds indicate during a respiratory exam?
● Suggest reduced air entry into that region of the lung (e.g pleural effusion, pneumothorax).
95
What is a wheeze?
● A continuous, coarse, whistling sound produced in the respiratory airways during breathing.
96
What is stridor?
● A high-pitched extra-thoracic breath sound resulting from turbulent airflow through narrowed upper airways.
97
What is coarse crackles?
● Discontinuous, brief, popping lung sounds
98
What is fine end-inspiratory crackles?
● Often described as sounding similar to the noise generated when separating velcro.
99
What would a wheeze indicate during a respiratory exam?
● Wheeze is often associated with asthma, COPD and bronchiectasis.
100
What would stridor indicate during a respiratory exam?
● Stridor has a wide range of causes, including foreign body inhalation (acute) and subglottic stenosis (chronic).
101
What would coarse crackles indicate during a respiratory exam?
● Typically associated with pneumonia, bronchiectasis and pulmonary oedema.
102
What would fine end-inspiratory crackles indicate during a respiratory exam?
● Fine end-inspiratory crackles are associated with pulmonary fibrosis.
103
Describe the technique for assessing vocal resonance during a respiratory exam?
1. Ask the patient to say “99” repeatedly at the same volume and in the same tone. 2. Auscultate all major regions of the anterior chest wall, comparing each side at each location.
104
What is the assessment of vocal resonance used for in a respiratory exam?
● The presence of increased tissue density or fluid affects the volume at which the patient’s speech is transmitted to the diaphragm of the stethoscope.
105
What would increased volume indicate during a vocal resonance assessment in a respiratory exam?
● Increased volume over an area suggests increased tissue density (e.g. consolidation, tumour, lobar collapse).
106
What would decreased volume indicate during a vocal resonance assessment in a respiratory exam?
● Decreased volume over an area suggests the presence of fluid or air outside of the lung (e.g. pleural effusion, pneumothorax).
107
What is an alternative method for assessing conduction of sound through lung tissue rather than by a vocal resonance assessment?
● Tactile vocal fremitus
108
What is an alternative method for assessing conduction of sound through lung tissue rather than by tactile vocal fremitus?
● Vocal resonance assessment
109
Describe the method of tactile vocal fremitus during a respiratory exam?
● Involves feeling for sound vibrations on the chest wall with your hands as the patient speaks.
110
Describe the method of palpating the lymph nodes during a respiratory exam?
1. Position the patient sitting upright and examine from behind if possible. Ask the patient to tilt their chin slightly downwards to relax the muscles of the neck and aid palpation of lymph nodes. You should also ask them to relax their hands in their lap. 2. Inspect for any evidence of lymphadenopathy or irregularity of the neck. 3. Stand behind the patient and use both hands to start palpating the neck. 4. Use the pads of the second, third and fourth fingers to press and roll the lymph nodes over the surrounding tissue to assess the various characteristics of the lymph nodes. By using both hands (one for each side) you can note any asymmetry in size, consistency and mobility of lymph nodes. 5. Start in the submental area and progress through the various lymph node chains.
111
Name some respiratory causes of lymphadenopathy?
● Lung cancer with metastases ● Tuberculosis ● Sarcoidosis
112
Describe how you would perform a posterior chest assessment during a respiratory exam?
● With the patient still sitting forwards, ask them to fold their arms across their chest so that their hands are touching the opposite shoulder. This results in rotation of the scapulae to better expose the underlying chest wall for assessment. ● Assess the posterior chest including inspection, chest expansion, percussion, tactile vocal fremitus (or vocal resonance) and auscultation.
113
What are the final steps to be perform during a respiratory exam?
● Assess for evidence of pitting sacral and pedal oedema (e.g. congestive heart failure). ● Assess the calves for signs of deep vein thrombosis (e.g. swelling, increased temperature, erythema, visible superficial veins) as the patient may have shortness of breath secondary to pulmonary embolism. ● Inspect for evidence of erythema nodosum, which can be associated with sarcoidosis.
114
How would you complete a respiratory examination?
● Explain to the patient that the examination is now finished. ● Thank the patient for their time. ● Dispose of PPE appropriately and wash your hands. ● Summarise your findings.
115
What further assessments and investigations could be performed, depending on your findings, during a respiratory exam?
● Check oxygen saturation (SpO2) and provide supplemental oxygen if indicated. ● Check other vital signs including temperature and blood pressure. ● Take a sputum sample. ● Perform peak flow assessment if relevant (e.g. asthma) ● Request a chest X-ray (if abnormalities were noted on examination) ● Take an arterial blood gas if indicated (also see ABG interpretation) ● Perform a full cardiovascular examination if indicated (e.g. cor pulmonale)
