ECG/RESP Monitoring

11.7 RESP Monitoring
11.7.1 Overview
Respiration is detected by measuring thoracic impedance. The monitor measures the
change of the impedanec between the RA and LA electrodes of the ECG lead I, or
the RA and LL electrodes of the ECG lead II, and produces a respiration waveform
as shown below.
Figure 11-31 Respiration Waveform and Parameter
1. Waveform name.
2. RESP lead: I or II
3. Waveform gain: 7 options are available: ×0.25, ×0.5, ×1, ×2, ×3, ×4, ×5. If the
gain is too large, the upper part of the waveform may not be normally
displayed.
4. RESP label: Selecting this label, you can open the RESP SETUP menu.
5. RR: Respiration rate numerics.
NOTE
z
Respiration monitoring is not recommended on patients who are very
active, as this will cause false alarms.
z
It is recommended to set Waveform gain to 1 when external
electromagnetic interference is great.
