To protect the MX40 from damage during defibrillation, to ensure
accurate ECG information, and to provide protection against signal
noise and other interference, use only ECG electrodes and cables
specified by Philips.
Philips recommends that you change the lead label only to reflect the
physical placement of electrodes. This will ensure a match between the
monitored lead and the label, and prevent any possible confusion.
Note— When switching from EASI to standard monitoring, there is a
momentary loss of data.
For Paced Patients
The output power of the MX40 and other sources of radio frequency
energy, when used in the proximity of a pacemaker, can be sufficient to
interfere with pacemaker performance. Due to the shielding effects of
the body, internal pacemakers are somewhat less vulnerable than
external pacemakers. However, caution should be exercised when
monitoring any paced patient.
In order to minimize the possibility of interference, position electrodes,
electrode wires, and the MX40 as far away from the pacemaker as
Consult the pacemaker manufacturer for information on the RF
susceptibility of their products and the use of their products with the
MX40. See the IntelliVue Information Center Instructions for Use for
additional information on monitoring paced patients.
When an external pacemaker is being used on a patient, arrhythmia
monitoring is severely compromised due to the high energy level in the
pacer pulse. This may result in the arrhythmia algorithm's failure to
detect pacemaker non-capture or asystole.
Pacemakers that create fusion beats (pace pulse on top of the QRS
complex) cannot be detected by the monitor's QRS detector.
