3-12 BeneVision N22/BeneVision N19 Patient Monitor Service Manual
3.4.2 Resp Performance Test
Tools required:
 Medsim300B patient simulator or other equivalent simulator
1. Connect the patient simulator to the module using a non ESU-proof cable and set lead II as the respiration lead.
2. Configure the simulator as follows: lead II as the respiration lead, base impedance line as 500 Ω; delta impedance
as 1 Ω, respiration rate as 20 rpm.
3. Verify that the Resp wave is displayed without any distortion and the displayed Resp value is within 20±1 rpm.
3.4.3 SpO
2
Test
Tools required:
 None.
1. Connect SpO
2
sensor to the SpO
2
connector of the monitor. Set Patient Category to Adult and PR Source to SpO2
on the monitor.
2. Apply the SpO
2
sensor to the ring finger of a healthy person.
3. Check the Pleth wave and PR reading on the screen and make sure that the displayed SpO
2
is within 95%
and100%.
4. Remove the SpO
2
sensor from your finger and make sure that an alarm of SpO
2
Sensor Off is triggered.
Measurement accuracy verification:
The SpO
2
accuracy of the MPM module has been verified in human experiments by comparing with arterial blood
sample reference measured with a CO-oximeter. Pulse oximeter measurements are statistically distributed and about
two-thirds of the measurements are expected to come within the specified accuracy range compared to CO-oximeter
measurements.
NOTE

A simulator cannot be used to assess the accuracy of a pulse oximeter monitor or a SpO
2
sensor. Instead, it can only verify that whether the monitor is functional. The accuracy of a
pulse oximeter monitor or a SpO
2
sensor needs to be verified by clinical data.
