Introduction

When using stainless steel or silver electrodes, a defibrillator discharge current may cause the electrodes to retain a residual charge causing a polarization or DC offset voltage. This electrode polarization blocks acquisition of the ECG signal. To avoid this condition, if there is a situation where a defibrillation procedure might be necessary, use non-polarizing electrodes (which do not form a DC offset voltage when subjected to a DC current) such as silver/silver-chloride types. If you use polarizing electrodes, GE Healthcare recommends disconnecting the leadwires from the patient before delivering the shock. Electrode defibrillation recovery is the ability of the electrode to allow the ECG trace to return after defibrillation. GE Healthcare recommends using non-polarizing disposable electrodes with defibrillation recovery ratings as specified in AAMI EC12 5.2.2.4. AAMI EC12 requires that the polarization potential of an electrode pair does not exceed 100 mV 5 seconds after a defibrillation discharge. Refer to the supplies and accessories reference guide for this system for a list of approved electrodes.

Accuracy of Input Signal Reproduction • Overall System Error meets AAMI EC11 3.2.7.1 requirements. Overall System Error is between or within ±5% or ±40 µV, whichever is greater. • Frequency Response meets AAMI EC11 3.2.7.2 requirements, using testing methods A and D. Frequency response is between or within ±10% between 0.67 and 40 Hz and between +0 and -10% for 20 ms, 1.5 mV triangular input.

Modulating Effects in Digital Systems This device uses digital sampling techniques that may produce some variation in amplitudes of Q, R, and/or S waves from one heart beat to the next, which may be particularly noticeable in pediatric recordings. If you observe this phenomenon, be aware that the origin of amplitude variations is not entirely physiological. For measuring voltages of Q, R, and S waves, GE Healthcare advises using the QRS complexes with the largest deflection of the particular waves.

EMI/EMC/RF Safety Information This system is designed and tested to comply with applicable regulations regarding EMC and must be installed and put into service according to the EMC information stated in the Electromagnetic Compatibility appendix of the Service and/or Operator’s manual. Changes or modifications to this system not expressly approved by GE Healthcare could cause EMC issues with this or other equipment. Mains power should be a standard commercial or hospital environment. Before installing or using the device or system, be aware of the proximity of known RF sources, such as the following: • Radio and TV stations • Portable and mobile RF communication devices (cell phones, two-way radios) • X-ray, CT, or MRI devices
