A patient monitor is an electronic medical device used to continuously measure and display a patient's vital signs. They are essential in ICUs, operating rooms, emergency departments, and general hospital wards.

Common monitored parameters

ECG / Heart rate and rhythm
Blood pressure (non-invasive and invasive)
SpO2 - blood oxygen saturation
Respiration rate
End-tidal CO2 (EtCO2)
Temperature

💡 Buying tip: When purchasing a refurbished patient monitor, confirm it includes all original modules, a valid calibration certificate, and a minimum 90-day warranty from the vendor.

Bedside vs. transport monitors

Bedside monitors are designed for stationary use in patient rooms and ORs, offering larger screens and more parameter options. Transport monitors are compact and battery-powered, designed to maintain monitoring during patient movement.

Major manufacturers

Leading patient monitor manufacturers include Philips, GE Healthcare, Mindray, Nihon Kohden, and Spacelabs. Each offers distinct product lines suited for different acuity levels and facility types.

New vs. refurbished

Refurbished patient monitors can offer savings of 40-70% compared to new list prices. When sourced from a certified vendor, refurbished units are fully tested, recalibrated, and include all necessary accessories.
