Ensure that the patient is not shivering.
Check the filter through
Check the electrodes and cables and their placement. See

Change the lead.
Remove the ECG cable from the connector and reinsert it.
Check that:
The pacer markers have been selected ON.
The pacemaker has been adjusted correctly and not above R.
The pacemaker functions correctly: ECG cables, electrodes and
setups are correct.
Check the electrode quality and positioning.
Adjust the detection limits. During ventilator-supported breathing, the
respiration calculation may count only ventilator-produced
inspirations and expirations.
Other electrical devices may interfere with the measurement.
Make sure there are no air bubbles in the transducer system. Flush
