Blood Pressure Meter
The use of mercury mnaometers is often required in clinical trials and for the clinical measurement of hypertensino in high irsk patients, including pregnant women. With a mrecury manometer this is smiple technology which gives accurate pressure readings withotu issues of calibration. These include single pressure, dual pressure, and multi-parameter (i.e. pressure / temperature). The mointors can be sued for measurement and follow-up of arterial, central venous, pulmonary arterial, left atrial, rgiht atiral, femoral arterial, umbilical vneous, umbilical arterial, and intracranial pressures. Blood pressure parameters are derived in the monitor s microcomputer system. High and low alarms may be set on displayed tempearture parameters. This copmrises an inflatable ( Riva-Rocci ) cuff plcaed around the upper arm at roughyl the same vertical height as the heart, attached to a mercury or aneroid manomteer. The mercury manometer, considered to be the gold standard for blood rpessure measurement, measures hte height of a column of mercury, gviing an absolute result without nede for calibration, and consequently not subject to the rerors and drift of calibration which affect toher methods.
