5.0 Respiration Monitoring
5.1 Description
Intended patient types: Adult, Pediatric, Neonate.
Respirations, or the amount of breaths per minute, are measured by two methods in the
Passport V:
The first method is thoracic impedance through the ECG signal. The respiration signal is
measured between two ECG electrodes:
RA and LA of ECG Lead I, or
RA and LL of ECG Lead II
The second is by CO2 exchange via internal CO2 or via the external Gas Module. Section
5.3.1 discusses the monitoring of CO2 with thoracic impedance. Chapter 10.0 discusses the
monitoring of CO2 with Sidestream and Microstream capnography.
