Infusion pumps
Use of an infusion pump may cause artifact in ECG signals. To
determine if the pump is the source of electrical interference in
the signal, turn it off, if possible. If the artifact disappears, it was
probably caused by the pump.
To minimize artifact and improve the signal, try the following:
! Choose ECG lead(s) with the best signal for monitoring or
replace the electrodes.
! Keep ECG cables away from the infusion pump and its wir-
ing.
Defibrillators and Cardioversion
WARNINGS:
! Before attempting a cardioversion, verify the timing
of the sync pulse on your monitor.
! Never place the defibrillator paddles over the ECG
electrodes or cables. The discharge can burn the
patient or the clinician, or fibrillate the clinician and
not defibrillate the patient.
High P-Waves and T-Waves
WARN IN G: The monitor may count high amplitude P or
T-waves (>0.2 mV) of long duration as QRS complexes.
This can result in missed low-rate alarms. If the dis-
played heart rate (HR) is higher than that indicated by the
waveform, the monitor may be counting unusually high
T-waves or P-waves as QRS complexes.
