EKG Machine Cleaning: A Comprehensive Guide for Healthcare Professionals

Rigorous cleaning of ECG machines prevents cross-contamination and ensures signal fidelity.

Materials

Step-by-Step

1. Power off & unplug. Remove all cables/leads.
2. Exterior: wipe housing, screen, buttons with disinfectant per contact time. Avoid liquid ingress.
3. Patient cables/leads: wipe entire length; clean connectors with 70% IPA; dry completely.
4. Electrode contact points: IPA swab; ensure no residue.
5. Printer: clean printhead per manufacturer (cleaning card or IPA swab); remove paper dust from compartment.
6. Inspect: check for cracked insulation, corroded pins, frayed wires. Replace damaged leads.
7. Test recording: verify signal quality, calibration.
