ECG and Heart Rate Monitoring
CAUTION – To avoid large offset potentials due to polarization of
electrodes, be sure to use pregelled, Ag/AgCl disposable electrodes, and
be sure that all electrodes used on a patient are of the same type.
Note – The HR/PR numeric is displayed in green when sourced from ECG (default). The
color changes to cyan or green respectively when sourced from SpO2 or an ART-labeled
IBP.
–
Note If an ECG waveform is not displaying on the PPM3, follow the instructions in the
chapter Working With Menus to select one or more ECG waveforms for display.
Note – Visually inspect the ECG cables on a daily basis and follow the instructions in the
Cleaning and Maintenance chapters as needed. Also, check for an inoperable ECG
circuit which would manifest itself as a blank ECG waveform and a "HR lead off"
message.
