Sensitivity Setup
The blood pressure values displayed on the monitor are resulting by averaging data sampled within a given
period of time. A shorter averaged time represents higher response speed of the monitor yet lower measuring
accuracy when the animal‘s blood pressure values are changing. Contrarily, a longer averaged time
represents lower response time of the monitor yet higher measuring accuracy when the animal‘s blood
pressure values are changing. A relatively short averaged time is conducive to analysis of conditions of
critical animals thatare being monitored.
Select [Sensitivity]: High, Mid and Low, and corresponding averaged time is about: 1s, 8s and 12s.
6.7.6 Sensor Zero-Calibration
The monitor needs an effective zero point to produce accurate pressure data, and please conduct zero calibrations
for sensors by following the hospital‘s rules and regulations. Zero calibration must be done in the following cases:
New sensors or sensor cables are used.
The monitor is restarted.
Reconnect the sensors‘ cables and the monitor.
The pressure data of the monitor is suspicious in its accuracy.
Zero Calibration Procedures:
1.
Connect the pressure sensors, sensor cables and the monitor as referred to Figure 6.26.
Figure 6.26 IBP Zero Calibration
2.
Close the animal‘s valve in the T-valve and expose the sensors to the air through the T-valve.
3.
Select IBP parameter region, e.g. Art-[Art Setup]-[Art Zero >>]-[Art Zero]. The option [Art Zero] is
displayed gray while zero calibrating; calibrated results are displayed when it is done and the [Art Zero]
is displayed normally.
4.
When zero calibration is completed, close the valve toward the air and open the one toward the animal.
