n CME : Your SA Journal of CPD - Assessment of cough
Cough remains one of the most common complaints that motivate patients to seek medical attention.
Cough is caused by stimulation of irritant receptors in the central airways and / or stretch receptors in the distal airways or the lung interstitium. It is a normal protective mechanism, which may be lost with local or general anaesthesia, other causes of decreased level of consciousness, or neuromuscular problems (especially bulbar). Cough is abnormal if it is persistent, painful or productive.
