Chapter 8 Respiration Rate (Resp)
8.1 Introduction
For the respiratory measurement (Resp), the monitor measures the thoracic
impedance between two ECG electrodes on the patient’s chest. Changes in the
impedance due to thoracic movement produce the Resp waveform on the
monitor screen. The monitor counts the waveform cycles to calculate the
respiration rate (RR).
8.2 Safety Information
Warning:
For the sake of safety, all the leads on the ECG cable must be
connected to patient.
When monitoring Resp, the ECG cable with electrotome-proof must
not be used.
The measurement of Resp is not applicable for patient with excessive
motion, otherwise it may cause the mistake of Resp alarm.
8.3 Monitoring Procedure
1. Connecting ECG Cable
To monitor Resp parameters, it is unnecessary to use other cables and it is
only necessary to use the ECG cable.
2. Placing Resp Electrodes
S
kin preparation for electrode placement refers to chapter 7.3.1. It is
unnecessary to use other electrodes for monitoring Resp, but it is very
important to place the electrodes. The Resp signal is always measured between
two of the ECG electrodes. If you are using standard ECG electrode placement,
Resp is measured between the RA and LL electrodes or between the RA and LA
electrodes.
