Non-Invasisve Blood Pressure Monitor
(Includes Pressure Cuff)
Product #: V72-34
|
Like the auscultatory method, the non-invasive, oscillometric method of measuring blood pressure employs a cuff. However this method does not use a microphone to "listen" for Korotkoff sounds as pressure falls. Rather, the oscillometric method senses the oscillations in the artery wall caused by turbulent blood flow and computes pressure from changes in the oscillations. A major advantage is that there is no microphone to place. Just place the cuff with its single tube . It is easier to use, more reliable and has no microphone to pick up ambient acoustic noise to render signal error. An empirically-developed, proprietary algorithm analyzes the oscillations over the course of the cuff deflation cycle and produces the measure. The pressures reported correlate very well with measured values from noninvasive transducers. The unit has both manual and computer controlled capabilities and displays systolic, diastolic, and mean arterial pressure as well as heart rate.
The V72-34 consists of the V-module, a remote cuff control unit (Cuff Linc) which contains the pump and a microprocessor to perform the analysis on the pressure signal, and an air-line-connected cuff. The module contains a second microprocessor to generate the display information and synthesize the analog outputs reflecting the measure.
A nice feature of this unit is that after the first cycle, the microprocessor remembers the pressure and pumps only to that level plus a 50 mm Hg margin rather than pumping to the initial target pressure of 180 mm Hg. When taking the first reading, it inflates to 180 mm Hg and if it detects no pulse, begins the deflate routine. If it does detect a pulse it will increase pressure in 40 mm Hg increments until it detects no pulse.
After 50 seconds, if the initial or subsequent target pressure is not reached, the unit will display the "Air Leak" message.
