6-2 ECG and Arrhythmia Monitoring
ECG Safety Information
Warnings
The MX40 operates exclusively via a wireless network connection,
therefore, it should not be used for primary monitoring in applications
where momentary loss of the ECG is unacceptable at the Information
Center. It sends ECG and optionally pulse oximetry data to the
Information Center, where the Information Center displays real-time
patient data, provides alarm annunciation, data storage and review
applications. The ECG waveform data, alarms and optionally SpO2 can
always be viewed on the MX40 regardless of the connection to the
Information Center.
Always confirm MX40 and Information Center observations with
clinical observation of the patient before administering interventions.
To avoid patient injury, assure that the patient cable is not positioned
where leads could become entangled around the patient, or cause
choking, strangulation, or inhibit circulation in extremities.
Every lead must be secured to an electrode on the patient. Conductive
parts of electrodes must not contact earth or other conductive parts.
EASI derived 12-lead ECGs and their measurements are
approximations to conventional 12-lead ECGs. As the 12-lead ECG
derived with EASI is not exactly identical to the 12-lead conventional
ECG obtained from an electrocardiograph, it should not be used for
diagnostic interpretations.
EASI lead placement is supported for adult patients only.
Ensure that the patient cable is properly connected to the MX40.
Do not mix and match electrodes of different types. In particular, do not
use electrodes of dissimilar metals. This helps ensure optimal signal
quality.
Non-manufacturer supplied accessories and supplies can corrupt the
performance of the equipment. Use only AAMI EC-12 compliant
electrodes with this device. Use of electrodes that are non-compliant
may provide erroneous results.
During complete heart block or pacemaker failure (to pace or capture),
tall P-waves (greater than 1/5 of the average R-wave height) can be
erroneously counted by the arrhythmia algorithm, resulting in missed
detection of cardiac arrest.
