ECG AND HR SAFETY CONSIDERATIONS
VF6 Infinity Vista 8-17
To minimize interference from ESUs, we recommend the following:
z Place the electrodes as far from the surgical incision as possible while
maintaining a clinically useful configuration.
z Place the cable and lead wires as far from the ESU as possible and
perpendicular to the ESU cables.
z Use an ESU neutral electrode with the largest possible contact area.
z When possible, place the ESU neutral electrode close to and directly under the
surgical site, avoiding bony protuberances.
z Replace the electrodes at regular intervals.
z Read the instructions provided with the ESU for additional information.
z For patients without a pacemaker, turn the pacer detection off. If pacer
detection is on, the ESU interference may be detected as pacer spikes that
display on the ECG.
The ECG waveform(s) and the HR value may be affected during electrosurgery.
However, after discontinuing the use of electrosurgery equipment, the waveform(s)
and value are displayed as normal.
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:
z Choose ECG lead(s) with the best signal for monitoring or replace the
electrodes.
z Keep ECG cables away from the infusion pump and its wiring.
Defibrillators and Cardioversion
WARNING:
z Before attempting a cardioversion, verify the timing of
the sync pulse on your monitor.
z 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.
