9 Monitoring SpO2

Understanding SpO2 Alarms

Understanding SpO2 Alarms

This refers to SpO2 specific alarms. See the Alarms section for general alarm information. SpO2 offers high and low limit alarms, and a high priority desat alarm. You cannot set the low alarm limit below the desat alarm limit.

CAUTION If you measure SpO2 on a limb that has an inflated NBP cuff, a non-pulsatile SpO2 INOP can occur. If the monitor is configured to suppress this alarm there may be a delay of up to 60 seconds in indicating critical patient status, such as sudden pulse loss or hypoxia.

Alarm Delays

There is a delay between a physiological event at the measurement site and the corresponding alarm at the monitor. This delay has two components:

•The time between the occurrence of the physiological event and when this event is represented by the displayed numerical values. This delay depends on the algorithmic processing and the configured averaging time. The longer the averaging time configured, the longer the time needed until the numerical values reflect the physiological event.

•The time between the displayed numerical values crossing an alarm limit and the alarm indication on the monitor. This delay is the combination of the configured alarm delay time plus the general system delay time (see “Monitor Performance Specifications” on page 342).

Adjusting the Alarm Limits

In the Setup SpO2 menu:

•Select High Limit then choose the upper alarm limit.

•Select Low Limit then choose the lower alarm limit.

WARNING High oxygen levels may predispose a premature infant to retrolental fibroplasia. If this is a consideration do NOT set the high alarm limit to 100%, which is equivalent to switching the alarm off. Transcutaneous pO2 monitoring is recommended for premature infants receiving supplemental oxygen.

Adjusting the Desat Limit Alarm

The Desat alarm is a high priority (red) alarm notifying you of potentially life threatening drops in oxygen saturation.

1In the Setup SpO2 menu, select Desat Limit.

2Adjust the limit.

Pleth Wave

The Pleth wave is autoscaled to maximum display size. It decreases only when the signal quality becomes marginal. It is NOT directly proportional to the pulse volume. If you need an indication of change in pulse volume, use the perfusion indicator.
