4.7.6 NIBP Pneumatics
How to check Interval 20 mmHg -> 185 mmHg
Select Start pump at different combinations of the valves open/closed and push the
ComWheel. The module counts the time it takes for the pressure to go up from 20 mmHg to
185 mmHg and displays it. When all the valves are closed, the pump should be able to pump
the pressure in about 1 to 4 seconds into an adult cuff wrapped around a rigid cylinder or pipe.
The pump does not stop without selecting
Stop Pump by pushing the ComWheel.
Start Pump/Stop Pump: A manual control for the
pump. The selection changes to Stop Pump when the
pump turns on.
Open Exh1/Close Exh1: A manual control for the
exhaust valve 1. The selection changes to Close Exh1
when the valve is opened. This function is not used
with E-PRESTN and E-PSM(P) modules.
Open Exh2/Close Exh2: A manual control for the
exhaust valve 2. The selection changes to Close Exh2
when the valve is opened.
Open Zero valve: A manual control for the zero valve.
This function is not in use with E-PRESTN and E-
PSM(P) modules.
Set Valve: The opening of the pulse valve is adjusted
between 0 and 255 (0 for fully closed and 255 for fully
open). First push the ComWheel, then turn it to adjust
the value on the screen and finally push to set the
value.
Reset Clock will zero the time on the display. This
function is not in use with E-PRESTN and E-PSM(P) modules.
