Implementasi alat ukur tekanan darah (sphygnomanometer) otomatis dengan bantuan personal komputer - Digital Collection of Petra Christian University

For years blood pressure meter depends only on feeling and skills from
medical operator, now automation has been introduced. SBP (Systolic Blood
Pressure) and DBP (Diastolic Blood Pressure) measurements on patient become
more easily nowdays, thanks to the invention of MOTOROLA pressure sensor.
MOTOROLA pressure sensor has two outputs, one is used as the cuff
pressure while the other is used to extract cuff pressure oscillations. The first
output directly interfaced with ADC (Analog to Digital Converter) to Personal
Computer using PPI (Programmable Peripheral Interface) Card. The other output
will be filltered and amplified before finally interfaced with ADC to PC through
the same PPI Card. Electronic Cuff Inflater will be controlled from PC using PPI
Card, the cuff pressure can also be monitored by bar mdicator on computer
screen. Meanwhile, for cuff exhaustion can be done manually by the patient.
Oscillations that occur during the measurements become the basic idea to
calculate SBP and DBP. Main menu software that will controll the entire
measurement system from PC has been made user friendly with extra information
for each command icons.
Digital result from the measurement on computer screen has made this
method can easily be read. In fact, the results after doing many measurement
experiments are less accurate plus there are instability on measurement results
during measurement. Measurement results vary in errors for different object of
measurement. Further development and research on wiring, repositioning
components and using very low noise components hopefully will improve
accuracy and stability of this electronic blood pressure meter.
