Patient and Operational Safety Notes
Your cardiograph isolates all connections to the patient from electrical ground
and all other conductive circuits in the cardiograph. This reduces the
possibility of hazardous currents passing from the cardiograph through the
patient’s heart to ground. To ensure the patient’s safety and your own, observe
the following reminders:
l When operating your cardiograph from AC power, be sure it and all
other electrical equipment connected to or near the patient are
effectively grounded.
l Use only grounded power cords (three-wire power cords with
grounded plugs). Also make sure the outlet accepts the plug and is
grounded. Never adapt a grounded plug to fit an ungrounded outlet by
removing the ground prong or ground clip. Should an ungrounded
plug adapter be necessary, use a ground strap to connect the
equipotential connector at the rear of the instrument to the power
source ground.
l The patient cable should be routed away from power cords and any
other electrical equipment. Failure to do so can result in AC power
line frequency interference on the ECG trace.
WARNI NG The patient cable supplied with this cardiograph, or an Agilent Technologies
approved substitute patient cable, is an integral part of the cardiograph’s safety
features. Using any other patient cable may compromise defibrillation protection as
well as cardiograph performance.
Only qualified personnel may service the cardiograph.
WARNI NG Do not use this cardiograph near flammable anesthetics. It is not intended for use in
explosive environments.
Do not touch the patient, patient cable or cardiograph during defibrillation. Death or
injury may occur from the electrical shock delivered by the defibrillator.
Be sure that the electrodes or lead wire tips do not come in contact with any other
conductive materials, including earth-grounded materials, especially when
