12-4 Dash 2000 Patient Monitor Revision C
2005873-001
Checklist
When starting respiration monitoring, the monitor ”learns” the patient’s
respiration pattern. Eight breaths are averaged and the average amplitude of
the respiration waveform is found. Detection sensitivity is automatically set at
40% of the average amplitude.
NOTE: The message ”LEARNING” is displayed in the RR values window
during this process.
Markers displayed on the waveform show this 40% detection range. One
marker is at inspiration, the other at expiration. The detection sensitivity can be
manually adjusted by using the SENSITIV option from the respiration menu.
The waveform size is also set automatically during the learning process, but
may be adjusted if necessary.
NOTE: Respiration detection is not dependent on the size of the
waveform. Size is for visual purposes only.
Even though the same electrodes are used for ECG and respiration monitoring,
it is possible to get a lead fail message for respiration without one for ECG.
The impedance may be too high for respiration detection, but the electrode is
still good for ECG. (Refer to Smart-Lead Fail in the ECG Monitoring chapter.)
Since respiration monitoring is so closely linked with ECG monitoring, patient
preparation and electrode placement are important. Please refer to the ECG
Monitoring chapter for guidelines.
1. Electrodes have been placed on the patient following proper skin
preparation.
2. Leadwires are attached to electrodes on the patient.
3. Leadwires are connected to patient cable and patient cable is connected
to the monitor.
4. Respiration setup is adjusted, if necessary. Follow detailed procedures
within this chapter.
