ECG Monitoring
Inputs: Single channel ECG may be viewed on display and printed. Pads
ECG is obtained through two multifunction defibrillation electrode pads.
Lead I, II, or III are obtained through the 3-lead ECG cable and separate
monitoring electrodes. With a 5-lead cable, leads aVR, aVL, aVF, and any one
of the V (1-6) leads can also be obtained.
Lead Fault: LEADS OFF message and dashed line appear on the display if
an electrode or lead wire becomes disconnected while a lead is selected.
Paddle Fault: NO PADDLES CONNECTED message and dashed line
appear on the display in Manual Mode if paddles become disconnected.
Pad Fault: PADS OFF message and dashed line appear on the display if a pad
becomes disconnected.
