Monitoring Respiration
Introduction
Overview
Respiration rate is detected by measuring thoracic impedance changes through ECG
lead I or lead II.
Lead I provides good thoracic (upper chest) breath detection. However, lead I is
more susceptible to cardiogenic artifact.
Lead II provides good thoracic breath detection and abdominal (lower chest)
breath detection. However, lead II is more susceptible to both cardiogenic artifact
and motion (head, neck or arm) artifact.
To enable respiration monitoring, select MORE MENUS > MONITOR SETUP >
PARAMETERS ON/OFF > RR.
A parameter window and waveform display when a patient cable is connected to the
monitor and respiration monitoring is enabled. The display is updated every two
seconds.

NOTE
Using an ESU ECG filter will not adversely affect respiration monitoring.
NOTE
When monitoring CO
2
, a respiration rate is always measured and displayed in the
CO
2
parameter window. Using the respiration rate measurement from CO
2
should be the preferred measurement method as an impedance respiration rate
can be disrupted by many conditions.
