Calibration Test Blood Pressure For Baumanometer Instruments Kit Black Each

Description

TESTING INSTRUMENT ACCURACY

Your goal is to test instrument accuracy, not the process of blood pressure measurement. You will need a Baumanometer® instrument (mercury-gravity standard) and a “Y” connector with an inflation bulb and valve attached (see below for Test Kit ordering information). Connect one leg to the Baumanometer® instrument and the other to the blood pressure instrument to be tested.

Note: Cuffs and Bags are not used when conducting this test. 

  The Pressure Standard: A Baumanometer® instrument is functioning correctly and should be used as the pressure standard if:

The mercury meniscus is at zero with no pressure applied to the instrument.

The instrument is in a vertical position. note: The Standby model is calibrated at a 20o angle

The instrument responds promptly to pressure changes.

Any two Baumanometer® instruments, regardless of age, will provide accurate linear pressure readings at every pressure level if they meet the stated criteria for a correctly functioning manometer.

Test Procedure: Check each instrument to be sure that it is at zero. Slowly inflate the instruments to 250 mmHg and compare the readings. They should be the same, however a deviation of +/- 3 mmHg is acceptable. Repeat this procedure at 200 mmHg, 150 mmHg, 100 mmHg, 50 mmHg and 0 mmHg. If the deviation is greater than +/- 3 mmHg at any of these points, the instrument being tested is inaccurate and needs adjustment or repair.
