Philips Heartstart MRx

The Philips Heartstart MRx is a lightweight, portable monitor/defibrillator. with the capability to offer four different modes of operation; monitor, manual Defibrillate, AED, and pacing. The Heartstart MRx defibrillator was designed to provide both monitoring and resuscitation by using mutual-parameter functions, including algorithms and options for transferring data to, a full range of defibrillation therapies. The Heartstart MRx is fast and reliable with 12-lead ECG and advanced STEMI support. The MRx has a large 8-inch color screen that can display up to 4 waveforms and numerics. The Philips Heartstar MRx additionally monitors other parameters: arrhythmia detection, SpO2, NIBP, IBP, EtCO2, and temperature.
