Setting up Spirometry
The following settings can be accessed through the Setup Spirometry menu.
Optimizing Scale Settings
In the Setup Spirometry menu, select Optimize Scales. The scale settings for all three spirometry
waves (AWF, AWP, AWV) will be optimized.
Spirometry Values Window
You can view all spirometry measurement data in the spirometry data window. In the Setup
Spirometry
menu, select Show All Values.
Alarms and Alarm Limits
Alarms can be derived from PEEP, PIP, MV and RRspir. In the Setup Spirometry menu you can set
the alarm limits. Refer to the Alarms chapter of this manual for details on alarm settings.
Changing the Apnea Alarm Delay
This determines the time limit after which the monitor alarms if the patient stops breathing.
1 In the Setup Spirometry menu, select RRspir.
2 In Setup RRspir 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.
• If an apnea occurs during a zero calibration or purge, the time delay between the start of apnea and
the activation of the apnea alarm could be up to 10 seconds plus the configured apnea delay time.
Automatic Alarm Suppression
If the automatic alarm suppression is switched on, all spirometry alarms are suppressed until breathing
activity has been detected. This setting must be made in configuration mode.
