Zoll Pro has one of the highest IP ratings in the industry and features a large LCD monitor that displays an SCA victim's 3 lead ECG directly on the screen. The Zoll AED Pro also includes many advanced features like Real CPR Feedback. This aids the rescuer in performing better CPR because the AED can give real-time feedback which informs you whether you need to press harder or pick up your pace. The Zoll AED Pro's ability to function in manual mode with an override function makes it ideal for professional rescuers. The Zoll AED Pro also offers the unique See-Thru CPR ability. This allows the rescuer to view the patient's ECG rhythm without interference from artifact noise caused by CPR, while continuing to perform continuous CPR at the same time. Uninterrupted CPR accompanied by quick utilization of the AED gives Sudden Cardiac Arrest victims their best chance of survival. Additionally, after the Zoll AED Pro is used, event rescue data can be downloaded easily from the device and used to improve future SCA outcomes. Zoll's free RescueNet software makes it simple.
