Verify status

After the transmitter leadwires have been properly attached to the patient's electrodes,

verify lead quality, electrode status and transmitter function.

Maintaining quality ECG signal

Electrodes are disposable and applied only once. Attempts to replace a loose

electrode guarantees excessive motion artifact and results in false alarms. Regardless

of patient type, electrodes should be replaced at least every 48 hours to maintain

quality signals during long-term monitoring. Over the course of 48 hours, the

electrode gel will start to dry out and the adhesive will age. This may irritate the

patient’s skin.

The transmitter must be carried securely on the patient. Stabilize the electrode and

leadwire with a leadwire stress loop near the electrode. Tape the stress loop to the

patient. A secured stress loop prevents the leadwire rotation about the electrode snap,

leadwire tugging at the electrode and ECG artifact.

306A

If the transmitter is allowed to dangle or jostle as the patient moves, then the weight

of the device will tug on the electrodes, causing degradation of the signal. Even if the

electrodes are in good contact, excessive tugging on the electrodes will change the

physical structure of the gel, thereby generating motion artifact signals. Transmitters
