C. SpO2 WAVEFORM AND BAR GRAPH
• The SpO2 waveform sweep speed can be selected from: 6.25, 12.5, 25, 50 and 100 mm/sec
in TRACE menu.
• The amplitude of the pulse waveform is automatically adjusted in screen.
• The Bar graph indicates the pulse signal height and varies from 1 to 8. Increasing the signal
amplitude increases the Bar graph value. Bellow number 2 in bar graph, the message WEAK
PULSE is displayed.
D. SpO2 ALARM LIMITS
• SpO2 Alarm Limits are set by default to:
SpO2 Upper Limit: OFF
SpO2 Lower Limit: 88 %
• Change the SpO2 Alarm Limits in the SpO2 menu.
SpO2 Upper Limit Range: 1 to 100 % – or OFF - non overlapping.
SpO2 Lower Limit Range: 0 to 99 % – or OFF - non overlapping.
• Pulse Alarm Limits are set by default to:
Pulse Upper Limit: 140 PPM
Pulse Lower Limit: 60 PPM
• Change the Pulse Alarm Limits in the SpO2 menu.
Pulse Upper Limit Range: 5 to 450 PPM – or OFF - non overlapping.
Pulse Lower Limit Range: 0 to 445 PPM – or OFF - non overlapping.
• The values selected are stored by the unit after power-off.
• To return to the factory default values, go to the SYSTEM menu and select the Load Factory
Default Settings.
E. SpO2 ALARM MESSAGES
SENSOR SpO2 -
Indicate that SpO2 probe is disconnected from the patient or the patient
cable is disconnected from the monitor or a malfunction in sensor or in
patient cable.
SpO2 LOW AND HIGH ALARM LIMITS - Indicate that SpO2 value overlap the LOW or HIGH
ALARM LIMIT selected.
WEAK PULSE -
Indicate the pulse signal amplitude is low causing instability in SpO2
monitoring. Check the probe installation, site perfusion and body
temperature.
CHECK SITE -
Indicate instability in the SpO2 readings. Verify the probe installation and
change probe site.
NO PULSE - Indicate the SpO2 pulse amplitude is smaller then the minimum pulse.
