8 Monitoring Respiration Rate (Resp)
188
Changing the Speed of the Respiration Wave
Resp waveforms are usually viewed at a slower speed than other waveforms. For this reason, the Resp
measurement has its own speed control and is not affected by the wave speed settings of the other
measurements.
• Select the Resp wave to enter the
Resp Wave menu, then select Change Speed. Choose the
required speed from the pop-up list. This defines the speed at which the wave is drawn across the
screen in millimeters per second (mm/s).
Using Resp Alarms
Resp alarms can be switched on and off and the high and low alarm limits can be changed just like
other measurement alarms, as described in the Alarms chapter.
Changing the Apnea Alarm Delay
The apnea alarm is a high priority red alarm used to detect apneas. The apnea alarm delay time defines
the time period between the point where the monitor cannot detect any respiration activity and the
indication of the apnea alarm.
1 In the Setup Resp menu, select Apnea Time.
2 Select the appropriate setting.
Resp Safety Information
WARNING
Respiration detection level
If you do not set the detection level for the respiration correctly in manual detection mode, it may not
be possible for the monitor to detect apnea. If you set the detection level too low, the monitor is more
likely to detect cardiac activity, and to falsely interpret cardiac activity as respiratory activity in the case
of apnea.
Apnea
The respiration measurement does not recognize obstructive and mixed apneas - it only indicates an
alarm when a pre-adjusted time has elapsed since the last detected breath.
The 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.
Interference
If operating under conditions according to the EMC Standard EN 60601-1-2 (Radiated Immunity 3V/
m), field strengths above 1V/m may cause erroneous measurements at various frequencies. Therefore
it is recommended to avoid the use of electrically radiating equipment in close proximity to the
respiration measurement unit.
Resp Accessories
To monitor respiration, use only the non-OR ECG accessories listed in the Resp section of the
accessories chapter. You cannot measure respiration if you are using an orange OR ECG cable set.
