Why does the doc. other asks me to cough?
Answers: 1) In checking the lungs there are repeatedly adventitious sounds or rhonchi caused by minor secretion or mucus in the bronchi. Coughing clears these sounds, so the physician can hear cleaner (or clearer) breath sounds.
2) Coughing briefly increases the intra-abdominal pressure. Thus if a manly has a small inguinal hernia, the examining physician may be aware of a bulge in that region when the long-suffering coughs.
They check for wheezing and signs if respiratory problems. Such as asthma.
