The Philips Heartstart MRx is a compact and portable device that serves as a monitor/defibrillator. It boasts the ability to operate in four different modes: monitor, manual defibrillate, AED, and pacing. The primary goal of the Heartstart MRx defibrillator is to combine monitoring and resuscitation capabilities through the utilization of mutual-parameter functions. These functions include algorithms and options for transferring data, thus providing a comprehensive range of defibrillation therapies.

When it comes to performance, the Heartstart MRx is both swift and dependable, thanks to its 12-lead ECG and advanced STEMI support. The device is equipped with a sizable 8-inch color screen that can display up to four waveforms and numeric data. Additionally, the Philips Heartstart MRx has the ability to monitor various other parameters, such as arrhythmia detection, SpO2, NIBP, IBP, EtCO2, and temperature.
