Transmitter Non-RF Application
Problems
LEADS OFF INOP
This INOP generally means that one of the patient leads
has fallen off the patient. It can also indicate a fault
within the transmitter.
1. A lead may have become disconnected from the
electrode. Go to the transmitter generating the
INOP and make certain that all leads are connected
to the electrodes on the patient’s body. The LEDs
on the front of the transmitter should be off if all
lead wires are attached properly.
If the leads are correctly connected, use the
Telemetry Service Tool or Wave Viewer at the
bedside to make certain there is a good waveform.
The transmitter can also be connected to a patient
simulator, if this is more convenient. Using the
Telemetry Service Tool or Wave Viewer, check the
following:
a. All available leads. If there is an ECG waveform
but no LEADS OFF-Check Transmitter INOP
on the Telemetry Service Tool or Wave Viewer,
the leads are connected.
b. If there is not a good waveform, check the leads
again and make certain they are applied properly
before continuing with the procedures. Proper
application of electrodes includes:
– Proper skin preparation.
– Using “moist electrodes”. If the gel on the
electrodes is not moist, the electrodes are too
dry to get a good signal.
– Making certain the connections are not dirty.
