MODEL RELEASED. Blood pressure gauge. Sphygmomanometer used to measure blood pressure in millimetres of mercury (mmHg). An inflatable cuff (brown,bottom right) is placed around the upper arm and inflated using a pump (bottom right) until blood flow in the arm stops. The cuff is then gradually deflated until pulsing blood flow is heard through a stethoscope. The reading on the blood pressure gauge at this point is the systolic pressure,which occurs during a heartbeat. The diastolic pressure,when the heart is relaxed,is taken by deflating the cuff until blood flows smoothly. Blood pressure is an important measure of health | |
