10 - 2 BeneVision N22/N19 Patient Monitor Operator’s Manual
10.1 ECG Introduction
The electrocardiogram (ECG) measures the electrical activity of the heart and displays it on the monitor as
waveforms and numerics. The monitor’s ECG module is integrated into the MPM module. ECG monitoring
provides 3-, 5-, 6-, and 12-lead ECG monitoring, ST-segment analysis, arrhythmia analysis, and QT/QTc
measurements.
10.2 ECG Safety Information
• This equipment is not intended for direct cardiac application.
• Make sure the conductive parts of electrodes and associated connectors for applied parts, including
the neutral electrode, should not contact any other conductive parts including earth.
• Use defibrillation-proof ECG cables during defibrillation.
• Do not touch the patient or metal devices connected to the patient during defibrillation.
• To reduce the hazard of burns during high-frequency surgical procedure, ensure that the monitor’s
cables and transducers never come into contact with the electrosurgery unit (ESU).
• To reduce the hazard of burns during use of high-frequency surgical unit (ESU), the ECG electrodes
should not be located between the surgical site and the ESU return electrode.
• Only use parts and accessories specified in this manual. Follow the instructions for use and adhere to
all warnings and cautions.
• Periodically inspect the electrode application site to ensure skin quality. If the skin quality changes,
replace the electrodes or change the application site.
• Interference from a non-grounded instrument near the patient and electrosurgery interference can
cause problems with the waveform.
• After defibrillation, the screen display recovers within 10 seconds if the correct electrodes are used
and applied in accordance with the instructions for use.
