ECG Safety Information
CAUTION
Interference from instruments near the patient and ESU interference can cause problems with the
ECG wave. See the monitor specifications for more information.
WARNING
Defibrillation and Electrosurgery:
Do not touch the patient, or table, or instruments, during defibrillation.
After defibrillation, the screen display recovers within 10 seconds if the correct electrodes are used and
applied in accordance with the manufacturers instructions.
ECG cables can be damaged when connected to a patient during defibrillation. Check cables for
functionality before using them again.
According to AAMI specifications the peak of the synchronized defibrillator discharge should be
delivered within 60 ms of the peak of the R wave. The signal at the ECG output on the IntelliVue
patient monitors is delayed by a maximum of 30 ms. Your biomedical engineer should verify that your
ECG/Defibrillator combination does not exceed the recommended maximum delay of 60 ms.
