Initial Deflation Test
In this test, the Press-Mate will inflate the 220 cc dummy cuff to about 180 mmHg, then slowly deflate the cuff
while calculating the operating parameters as follows:
COUNTS
Time from the beginning of the deflation period to the point at which the cuff pressure is
25 mmHg below the initial inflated cuff pressure (180 mmHg).
MAXPRESS
Maximum deflation rate from the beginning of the deflation period to the point at which the cuff
pressure is 40 mmHg below the initial inflated cuff pressure.
a. Connect the 220 cc dummy cuff to the cuff connector.
b. Press the START/STOP switch to start the test.
c. The 220 cc dummy cuff will inflate to 180 mmHg and then slowly deflate the cuff while calculating
the operating parameters. The initial deflation parameters, COUNTS, and MAXPRESS are
displayed in the SYSTOLIC and DIASTOLIC windows (MEAN window for model 8800 Press-
Mates). The acceptable range is as follows:
COUNT
5 — 13
MAXPRESS
4 — 10
60
Deflation Test
a. Attach the 220 cc dummy cuff to the cuff connector (See Figure 7.2).
b. Press the START/STOP switch to start the test.
c. The 220 cc dummy cuff will inflate to about 300 mmHg, then slowly deflate while calculating the
deflation rate.
d. When the test is complete, results will be displayed in the SYSTOLIC, DIASTOLIC, PULSE, and
TEMP windows (SYSTOLIC, MEAN, DIASTOLIC, and PULSE windows in model 8800 Press-
Mates) in mmHg/sec, less the decimal points (e.g., 40 = 4 mmHg/sec). Acceptable ranges are as
follows:
