Monitoring Resp
10.1 Resp Introduction
Impedance respiration is measured across the thorax. When the patient is breathing or ventilated, the volume of
air changes in the lungs, resulting in impedance changes between the electrodes. Respiration rate (RR) is
calculated from these impedance changes, and a respiration waveform appears on the equipment screen.
Resp monitoring is intended for adult, pediatric and neonatal patients.
10.2 Resp Safety Information
WARNING
•
When monitoring the patient’s respiration, do not use ESU-proof ECG cables.
•
The respiration measurement does not recognize obstructive and mixed apneas: it only indicates an
alarm when a pre-adjusted time had elapsed since the last detected breath. The safety and
effectiveness of the respiration measurement method in the detection of apnea, especially the
apnea of prematurity and apnea of infancy, has not been established.
10.3 Resp Display
10.4 Placing Resp Electrodes
As the skin is a poor conductor of electricity, preparing the skin is necessary for a good respiration signal. For
details, refer to
5.4.1 Preparing the Patient Skin .
As the Respiration measurement adopts the standard ECG electrode placement, you can use different ECG
cables (3-lead or 5-lead). Since the respiration signal is measured between two ECG electrodes, if a standard ECG
electrode placement is applied, the two electrodes should be RA and LA of ECG Lead I, or RA and LL of ECG Lead
II.
