WARNING
1 Do not apply it during electro-surgery or MRI; otherwise it might result in harming the
patient or the operator.
2 Always check if the alarm settings are appropriate for your patient before starting
monitoring.
3 Check for any fault of the transducers before applying them to the patient.
NOTE:
This feature is only available on F6 Express.
9.1 Maternal ECG Monitoring
9.1.1 Introduction
ECG monitoring produces a continuous wave form of the patient’s cardiac electric activity to
enable an accurate assessment of current physiological state. Only proper connection of ECG
cables can ensure a satisfactory measurement.
The parts needed are ECG lead and electrodes.
A 20-second monitor stabilization period shall be allowed before testing. The monitor has Tall
T-wave rejection capability.
The response time of heart rate meter to change in heart rate is less than 10s.
The minute heart rate display is updated at an interval of 1s.
The monitor does not have capability of detecting or rejecting pacemaker pulse, nor does it
provide a pulse to synchronize a defibrillator discharge.
The monitor does not give alarm for tachycardia.
The d.c. offset voltage tolerance of the monitor is from -500mV to +500mV. If the d.c. offset
voltage of the detected ECG signal is out of this range, the monitor issues a high level alarm:
ECG SINGNAL EXCEEDS LIMIT.
WARNING
1 When connecting the cables and electrodes, make sure no conductive part is in
contact with the ground. Verify that all ECG electrodes, including neutral electrodes,
are securely attached to the patient.
2 The electrodes should be made of the same metal materials.
CAUTION
A different type of electrodes may produce higher offset voltage. Therefore, only use the
ECG leads supplied by the manufacturer when using the monitor for ECG monitoring.
