RESP System Message
When monitoring Respiration using impedance pneumography, the X Series unit may display
the following message:
System Message Cause
RESPIRATION FAULT The impedance measured through the ECG lead is
too high for the unit to detect Respiration changes,
but not high enough to indicate an ECG lead fault
(the impedance may vary between 1800 and 2800
ohms).
