Defibrillator HEARTSTART MRx

HeartStart MRx: Advanced Defibrillator-Monitor for Critical Care

The Philips HeartStart MRx is a comprehensive defibrillator-monitor designed to meet the demanding needs of emergency medical services (EMS), hospitals, and military settings. Built to be rugged, reliable, and easy to use, the MRx combines powerful resuscitation therapies with advanced patient monitoring to deliver critical care in a variety of challenging environments. Whether used in an ambulance, on a military helicopter, or in a hospital, the HeartStart MRx offers the technology, performance, and durability that healthcare professionals need to make lifesaving decisions with confidence.

At the core of the HeartStart MRx is Philips' industry-leading DXL 12-lead ECG algorithm. This advanced technology provides comprehensive diagnostic measurements that aid in the detection and treatment of cardiac conditions, particularly ST-elevation myocardial infarction (STEMI). The DXL algorithm enhances clinical decision-making by delivering predictive tools and precise data, enabling healthcare providers to accelerate triage and treatment times. In addition to the 12-lead ECG, the MRx supports continuous monitoring of essential parameters such as SpO2, non-invasive blood pressure (NBP), CO2, and more. These capabilities ensure that clinicians have access to the rich clinical information necessary to drive patient care and improve outcomes.

The HeartStart MRx is designed with a focus on effective resuscitation. It offers both manual defibrillation and automated external defibrillation (AED) modes, with biphasic truncated exponential waveforms optimized for patient impedance. In AED mode, the device delivers a consistent 150 Joules of energy to patients, guided by shock advisory features that meet stringent AAMI DF-39 guidelines. For more advanced cases, the MRx includes noninvasive pacing with adjustable current pulse amplitudes and demand or fixed-rate pacing options, giving clinicians the flexibility to stabilize critical patients.

One of the standout features of the HeartStart MRx is the Q-CPR measurement and feedback tool. This system helps improve the quality of cardiopulmonary resuscitation (CPR) by providing real-time feedback on compression depth, rate, and ventilation, ensuring that CPR is administered correctly and effectively. By guiding rescuers through proper technique, the MRx plays a key role in increasing survival rates for cardiac arrest patients.

The HeartStart MRx is engineered to withstand the most extreme conditions. Its rugged design has earned Airworthiness Certification from the U.S. Army, signifying that it meets strict standards for vibration, mechanical shock, and environmental exposure. The MRx can endure everything from water spray to helicopter vibrations, high-altitude operations, and wide temperature variations ranging from freezing cold to intense heat. 

The HeartStart MRx offers flexible data storage and transmission options, making it easier for healthcare teams to access and share critical patient data. The device stores up to 12 hours of continuous ECG waveforms and events, along with 50 12-lead ECG reports. Data can be stored internally or on a CompactFlash memory card for added convenience. Additionally, the MRx supports wireless data transmission via Bluetooth®, allowing for the seamless transfer of information to hospital systems or remote care providers.

Philips designed the HeartStart MRx with a scalable platform, meaning that it can be easily upgraded in the field to incorporate the latest technological advancements without increasing the size or weight of the device. This ensures that healthcare providers can continue to benefit from Philips’ innovations while maintaining the same reliable performance and ease of use. The MRx’s backward compatibility also allows for the use of existing accessories and software, providing a cost-effective solution for organizations looking to modernize their emergency response equipment.

The HeartStart MRx features a simple and intuitive interface that makes it easy to operate in high-stress situations. Its clear indicators, buttons, and operating modes are designed to help users quickly access the necessary functions. In addition, the MRx can be paired with the Philips HeartStart FR3 AED for hands-free operation, streamlining the resuscitation process and allowing healthcare providers to focus on other critical tasks. This integration eliminates the need to change paddles between devices, further enhancing the efficiency of emergency care.
