NIBP (Non-Invasive Blood Pressure) Function
A stepping motor and piston pressure engine is used to generate the output waveforms. A
precision pressure sensor is used to measure the pressure of the cuff. The pressure
sensor is read by a 16-bit differential Analog to Digital converter.
The cuff pressure is monitored and the motor/piston assembly reacts to provide the correct
response based on the selected mode.
IBP (Invasive Blood Pressure) Function
A Digital to Analog converter is used to generate the IBP waveforms. The output circuit is
fully isolated and capable of switching between the two standard sensitivities (5
µV/V/mmHg and 40 µV/V/mmHg).
Temperature
There is an 8-pin mini-DIN plug connector on the right side of the unit for connection of
a Temperature cable. Temperatures are simulated for both YSI 400 and YSI 700 probe
types. There are seven different temperatures selectable for each.
