Figure 3. The
pressure gauge (Digiquartz/model No.6000-15G,
Paroscientific INC.) had the error below 0.01% and was
traceable to the national standard of Korea by ourselves. The
measured signal passed the converter (model No. 6671-003,
Paroscientific INC.) and was recorded in a notebook
computer. The recording was controlled by the software
programmed by Lab-view.
The KRISS simulator was compared with commercial
simulators. The commercial simulators were BP Pump2
(Fluke), Simcube SC-1(Pronk Technologies) and Clinical
Dynamics SmartArmTM (Clinical Dynamics Corporation)
(Figure 4). Each simulator was controlled to generate the
systolic pressure of 120 mmHg, the diastolic pressure of 80
mmHg and the pulse of 75. For the comparison, the
commercial oscillometric BP device (model 770A, Omron
Co.) was connected like Figure 5 and the value of BP at each
time was recorded by 5 times for each simulator.
Finally, we investigated the measurement repeatability of BP
using the 6 models of commercial oscillometric BP devices
from 5 companies and the KRISS simulator. The models were
summarized in Table I. The experimental connection was like
Fig.5 and the KRISS simulator controlled to generate two
conditions; systolic pressure 120 mmHg/diastolic pressure 80
mmHg/pulse 75 and systolic pressure 150 mmHg/diastolic
pressure 94 mmHg/pulse 75. The measurement was
conducted by 5 times for each condition.
