Question 1

Respiratory

Answer 1

achea position, lymph nodes
Shape, scars, respiratory rate
Expansion, vocal fremitus
For presence of dullness
Breath sounds, presence of wheezes or crackles, vocal resonance
The time taken to expire a given volume or a given fraction of vital capacity during
measurement of forced vital capacity. Aims to quantify airway obstruction at the
bedside by measuring the time taken for forced expiration. It is measured over the
trachea with a stethoscope, take a deep breath in and breathe out as quickly as
they can. More than 6 seconds suggests airway obstruction. Three consistent
readings are needed. Forced expiratory time has been found to correlate weakly
with spirometric parameters with a sensitivity of 61% and a specificity of 79% in
predicting obstructive airway disease when compared with simple spirometry. On
the other hand, the sensitivity and the specificity of forced expiratory time in predicting small airway disease were 47% and 86%, respectively.
