The Philips HeartStart XL M4735A is designed to effectively handle various resuscitation and monitoring tasks, making it an essential tool in emergency situations. This compact and portable device functions as a semi-automatic external defibrillator and offers two operational modes: Automated External Defibrillation (AED) and Manual. Both modes utilize the efficient low-energy SMART Biphasic waveform, which enhances the effectiveness of defibrillation.
