Question

The regular BP cuff is a non – invasive method of measuring blood pressure.

(a) True

(b) False

This question was posed to me in a national level competition.

The origin of the question is Measuring Blood Pressure & Pulse Oximetry in portion Diagnostic Investigation in Neurology and Cardiology of Clinical Science

Answer 1

The correct option is (a) True

To explain I would say: BP cuff is a non invasive method of measuring blood pressure. The measuring is done by checking the pressure being applied to the mercury column due to the inflated cuff. When the cuff is inflated, it is in close contact with the arteries. Thus, the flowing blood in the arteries puts pressure on the inflated cuff which is recorded and represented by the mercury column.
