About the Oscillometric Method
The oscillometric method measures the blood pressure by detecting the
pulse oscillation change with the cuff pressure. The cuff connects to the
NIBP cuff connector on the monitor via the air hose. The air pressure
inside the cuff is converted to electrical voltage by the pressure sensor,
converted into a digital signal (A/D conversion), and communicated to the
CPU section. Measurements operate according to the following cycle.
1) The cuff inflates to the set value and inhibits the arterial blood flow
at the measured site.
2) The cuff gradually deflates.
3) The arterial blood flow of the patient will return when the cuff
pressure is decreased sufficiently.
4) The oscillation (pulse signal) caused by the restricted blood
circulation is transmitted to the pressure sensor via the air hose,
and converted to an electric signal.
5) From the pulse signal and cuff pressure detected at the pressure
measurement circuit, the systolic, diastolic, average blood pressure
and pulse rate will be measured at the CPU.
Memo
The systolic, diastolic, mean blood pressure will be displayed on the
monitor. The measurement will start with the following factor.
1) When the (NIBP Start/Stop) key is pressed.
2) At the selected measurement interval.
3) If "NIBP Measurement at Alarm" is set ON, and an alarm is
generated.
Procedure for Periodic Measurement
NIBP measurement will be performed automatically at selected time intervals.
1 Press the (Menu) key and select “Parameter Setup” >“NIBP
Setup”>”Measurement Interval Setup”.
Or, press the
(NIBP Auto Mode) key.
The "Measurement Interval Setup"
window will be displayed.
2 Select from [Cont.]/[1]/[2]/[2.5]/[5]/[10]/[15]/[30]/[60]/[120] (Min.).
