A sphygmomanometer (/ ˌ s f ɪ ɡ m oʊ m ə ˈ n ɒ m ɪ t ə r / SFIG-moh-mə-NO-mi-tər), also known as a blood pressure monitor, or blood pressure gauge, is a device used to measure blood pressure, composed of an inflatable cuff to collapse and then release the artery under the cuff in a controlled manner, [1] and a mercury or aneroid manometer to measure the pressure.
Mercury is a useful material to use in a manometer because of its high density. This means that a much shorter column is needed compared to water. [ 2 ] For instance, the pressure represented by a column of 100 mm of water is just under 7.4 mm of mercury ( mmHg ).
Pressure sensors can alternatively be called pressure transducers, pressure transmitters, pressure senders, pressure indicators, piezometers and manometers, among other names. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area.
It is a marker of respiratory muscle function and strength, [4] represented by cmH 2 O and measured with a manometer. MIP is an important and noninvasive index of diaphragm strength and an independent tool for diagnosing many illnesses. [5] Typical MIPs in adult males can be estimated from the equation M IP = 142 - (1.03 x Age) cmH 2 O, where ...
A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution. [10] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a ...
Duct leakage test in the US. A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork.
Scuba diver of the late 1960s. The history of scuba diving is closely linked with the history of the equipment.By the turn of the twentieth century, two basic architectures for underwater breathing apparatus had been pioneered; open-circuit surface supplied equipment where the diver's exhaled gas is vented directly into the water, and closed-circuit breathing apparatus where the diver's carbon ...
