FDA Product Code MHX: Monitor, Physiological, Patient(with Arrhythmia Detection Or Alarms)

Detecting life-threatening arrhythmias in real time is one of the most critical functions in patient monitoring. FDA product code MHX covers physiological patient monitors with integrated arrhythmia detection.

These systems continuously measure and display vital signs — including ECG, heart rate, blood pressure, and oxygen saturation — while automatically alerting clinicians to dangerous rhythm abnormalities. They are used in intensive care units, cardiac telemetry wards, and operating rooms.

MHX devices are Class II medical devices, regulated under 21 CFR 870.1025 and reviewed by the FDA Cardiovascular panel.
