Answer:
A stethoscope identifies the precise point when the pulse sound returns and the pressure of the cuff is slowly released. Using the stethoscope enables the person measuring the blood pressure to listen out for two specific points.
Blood pressure readings consist of two figures – the systolic pressure first and the diastolic pressure second. The reading is given as, for example, 140 over 90 mm Hg.
The systolic pressure is the higher figure caused by the heart’s contraction, while the diastolic number is the lower pressure in the arteries, during the brief ‘resting’ period between heartbeats.
