B30 Patient Monitor
RESP - WAVE - NORM
RATE - 20
OHMS - 1.0
RATIO - 1/1
APNEA - OFF
SHIFT - OFF
Check that the RESP waveform is shown and the RR value is 20 (±5). Change the position
of the BASELINE IMPEDANCE switch and check that appropriate RESP waveform and RR
value are shown again within 30 seconds.
RESP - APNEA - 32 S
Check that the monitor activates the APNEA alarm.
NOTE: Make sure that only the ECG leads are connected to the simulator during the
apnea test. If other cables are connected at the same time, the respiration signal from the
simulator may be disturbed, and therefore, the APNEA alarm may not be activated.
NOTE: When you have the ECG service menu open, spikes will appear on the respiration
waveform. These spikes represent the threshold level for detecting inspiration and
expiration.
Temperature measurement
9. Communication and memories
Enter the PSM: STP service menu:
Parameters - STP
Check that the Time-outs, Bad checksums and Bad c-s by mod values do not increase
faster than by 5 per second. Check also that the STP board memories have passed the
internal memory test, i.e. the RAM, ROM and EEPROM show all OK.
10. Temperature probe detection
Check that the 'Cable' and 'Probe' show OFF for both channels, T1 and T2, when no
probes are connected.
Connect the temperature adapter cable to the module temperature connector and a
temperature test plug to the adapter cable. Check that the Cable and Probe for T1 show
ON and the corresponding temperature value appears on the monitor screen.
11. Calibration check
Check the temperature calibrations using temperature test plugs.
If the deviation on a temperature reading on the screen is more than 0.1°C, calibrate the
temperature channels according to the instructions in chapter
12. Temp test
