To change the imCO
2
high limit:
•Select
imCO₂ High and choose the high alarm limit from the pop-up list that opens.
Changing the Apnea Alarm Delay
This determines the time limit after which the monitor alarms if the patient stops breathing.
1 In the Setup CO₂ menu, select awRR.
2 In Setup awRR menu, select Apnea Time.
3 Choose the apnea alarm delay time.
WARNING
Safety and effectiveness of the respiration measurement method in the detection of apnea,
particularly the apnea of prematurity and apnea of infancy, has not been established.
Prolonged delay: The selected apnea alarm delay may be prolonged by up to 17 seconds, if an apnea
occurs during the automatic zero process. This applies to the Microstream (M3015A) measurement
only.
Deriving Alarms From awRR
1 In the Setup CO₂ menu, select awRR.
2 In the Setup awRR menu, select Alarms.
3 Choose On to derive alarms from the airway respiration signal or Off to disable them.
Changing awRR Alarm Limits
1 In the Setup CO₂ menu, select awRR.
2 Select High Limit to set the upper alarm limit.
Select
Low Limit to set the lower alarm limit.
3 Select the appropriate setting.
Changing IPI Alarm Limits
1 In the Setup CO₂ menu, select IPI.
2 Select Low Limit to set the low alarm limit.
3 Select a value between 2 and 9.
If you also have monitors with earlier software revisions than J.0, the IPI low alarm will not be
generated after a transfer to one of these monitors, or when a monitor/MMS with the IPI functionality
is connected to one of these monitors in companion mode. In this case, do not rely only on the IPI
low alarm but leave the individual alarms switched on (etCO
2
, awRR, pulse rate and SpO
2
) so that
these alarms can be generated in such situations.
