CMS surveyors specifically look for PM documentation, calibration records, and PCREE test reports when conducting Life Safety reviews. A monitor delivering inaccurate readings is not only a clinical risk — it's a citation waiting to happen.
Medical Equipment Repair Network connects skilled nursing facilities, hospitals, and clinics with biomedical technicians who carry calibrated patient simulators for all major vital sign monitor brands. We provide output verification, electrical safety testing, and CMS-ready written documentation for every device we service.

Frequently Asked Questions
Proper calibration requires a calibrated patient simulator that supports the specific channels in your monitor — SpO2, NIBP, temperature, and ECG/heart rate. The simulator itself must have a current calibration certificate traceable to NIST standards. Our technicians carry appropriately calibrated simulators for all major monitor brands.
Most manufacturers recommend annual PM and calibration. Monitors used in high-acuity or continuous monitoring settings benefit from semi-annual review. Any monitor that has been repaired or shows suspect readings should be re-verified before returning to patient care.
Each monitor receives a written service record documenting calibration results per channel, PCREE electrical safety measurements, any repairs performed, technician credentials, and service date. This record is formatted to meet CMS survey documentation requirements.
Patient-applied pulse oximeters used in direct patient care settings are subject to NFPA 99 PCREE testing requirements. This includes standalone bedside units and handheld oximeters in SNF and clinical settings. Battery-only oximeters with no AC connection are generally lower risk but should still be documented in your PM program.
