value of blood pressure pump will recover the initial settings. When blood pressure pump is
not working properly but the monitor does not question why, this is the recommended key.
Because it allows self checking of blood pressure pumps, allowing automatic recovery of
pump exception due to some accident.
CONTINAL : After select continuous measurement, the menu will disappear automatically
and continuous measurement starts immediately; If you want to stop it, press the key of blood
pressure measurement on the shell.
CALIBRATE :
(pressure calibration)
For calibration of NIBP pressure, it should be carried out at least every two years or when do
you think the value is not accurate.
PENUMATIC
(Leak detection):For detecting the closed conditions of NIBP gas path
DEFAULT: Select this item to enter "NIBP default settings" dialog box, the user can choose
"no" or "Yes" to exit or select "the default configuration is to be used, the original
configuration will be overwritten."
14.5 NIBP Pressure Calibration
The manufacturer recommends to use pressure meter or mercurial sphygmomanometer with
calibrated precision higher than 1mmHg for calibration. Users can select the Calibration item to
start calibration, while this item turns to be “Stop calibration”; if at such moment press the button,
the system will stop calibration.
Warning
Calibration for NIBP measurement should be done every two years (or conducted
following the maintenance plan of your hospital). Please follow the following details to
check its performance.
14.5.1.1 Calibration procedures of a pressure sensor:
Use a metal container of 500ml±5％ to replace cuff. Connect a calibrated standard pressure meter
with inaccuracy less than 0.8mmHg, T-interface ball pump and the pumping tube into the NIBP
holes on the module. Set the monitor to be under “Standard” mode, then take the ball pumps to
pump the metal container to be 0, 50 ad 200mmHg; in such cases values of standard pressure
meter and press values indicated on the monitor will differ within 3mmHg, otherwise please
contact with our Maintenance engineers.
