19 Monitoring Maternal Heart / Pulse Rate
160
Adjusting the Heart Rate / Pulse Alarm Limits
To adjust the pulse alarm limits:
1 In the Setup SpO₂ menu, select Pulse (SpO₂). This opens the Setup Pulse (SpO₂) menu.
2 Ensure Pulse (SpO₂) is On. Select Pulse (SpO₂) to toggle between On and Off.
3 Set the pulse alarm limit:
– Select
High Limit then choose the upper alarm limit for tachycardia from the pop-up list.
– Select
Low Limit then choose the lower alarm limit for bradycardia from the pop-up list.
Average Pulse Rate from Noninvasive Blood
Pressure
WARNING
No alarm is possible when noninvasive blood pressure is the source of the pulse rate.
When you are measuring noninvasive blood pressure, the monitor can also calculate the average pulse
rate. This occurs in either manual or automatic mode, when neither MECG, SpO
2
nor pulse from
Toco MP is being measured. The value is displayed on the screen, and printed on the trace. It is not the
actual pulse value, but an average pulse rate, taken during the most recent noninvasive blood pressure
measurement. The value is updated after each successive measurement. If you need a continuous
measurement, you should monitor using MECG, SpO
2
or pulse from Toco MP.
Troubleshooting
Testing MECG Mode
Refer to the monitor's Service Guide.
