9. Adjusting Deflation Rate
Your ADC ® Blood Pressure Instrument is equipped with an automatic deflation valve that releases air at the fac-
tory preset rate of approximately 2-5 mmHg per second in accordance with the recommendations of the American
Heart Association. Correct deflation rate is essential to accurate readings.
The deflation rate is influenced by cuff size. If using a cuff other than the one shipped with the unit, you may have
to adjust the deflation rate.
1. To check the rate, begin the measurement procedure by following the instructions listed
on pages 12-16.
2. Observe the positions of the indicator needle for a 10 second period during deflation.
Subtract the reading at the end of the test from the reading at the beginning and
divide by 10. If the rate is 2-5mmHg no further adjustment is needed.
For example, if at the beginning of the test the reading was 180 and at the end
the reading was 130, during a 10 second period, the rate of deflation is 5.
(180-130=50, 50 /10=5).
If the deflation rate is not within this range, the valve should be adjusted as follows:
1. The deflation rate adjustment screw is located on the push button of the automatic valve. With a small, flathead
screwdriver, rotate adjusting screw approximately 1/8 turn clockwise to increase deflation speed, or counterclockwise to
decrease speed.
2. Repeat test to determine deflation rate.
3. Continue this process until the deflation rate is between 2-5mmHg.
Note: The adjustment screw is very sensitive and should be rotated gradually.
10. Ordering A Different Cuff
Use of a correctly sized cuff, along with proper positioning of the cuff, are essential to accurate measurements.
The ADCUFF TM , with its proprietary Size Guide TM marking system, simplifies correct cuff application and helps
prevent ”miscuffing.“ The ADCUFF TM for Home is available in three sizes. If you need to order a size other than
the one included with the instrument, call 1-800-ADC-2670.
