Monitoring Resp
10.1 Overview
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.
10.2 Safety
WARNING
z
When monitoring the patient’s respiration, do not use ESU-proof ECG cables.
z
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.
