Portable pulse meter. Man's wrist wearing a portable digital sphygmomanometer displaying his resting pulse rate. Pulse rate is a measurement,expressed in beats per minute,of the heart pumping blood through the arteries. An inflatable cuff (grey) around the wrist is connected to a digital electronic device. The cuff is inflated exerting pressure which stops blood flow in the arm. The pressure is released,and the pulse rate (66) is displayed. Measurements for systolic and diastolic blood pressures are also displayed (not shown here),expressed in millimetres of mercury (mm Hg). (See M390/258 for a photo of this machine displaying blood pressure measurement.) | |
