The ZOLL Company has over fifty years of experience in the field of resuscitation, and the company prides itself in providing good, sound external defibrillators. Most recently, they have come out with the M series, yet plenty of their early models had excellent features.

With the PD 1200, it combines defibrillation, pacing and monitoring, and it can be configured with multi-function electrodes that are "hands-off." It comes with both standard defibrillator paddles and internal ones. Both, of course, have pacing electrodes. As for power, it can use either an AC line or battery, and is completely compatible with all of the ZOLL cardiac resuscitation system models. It also features a pacemaker, non-fade monitor, an ECG monitor and a strip recorder.

In the case of the PD 1400, it also incorporates a pacemaker into its design, and comes with the multi-function electrodes or the standard defibrillation paddles and pacing electrodes. It's been built to allow for ease of use, maximum flexibility, and complete compatibility with other models in the integrated ZOLL system. Like the 1200, it comes with an ECG monitor and strip recorder. The 1600 model offers one of the best features: a voice recording system, and it can switch between semi-automatic and manual defibrillation modes.

In the PD 2000, a Defibrillator Advisory Defibrillator/Pacemaker is a completely integrated system for early defibrillation and advanced cardiac life support in the hospital. The built-in ventricular fibrillation detection system eliminates adapters and a "paddle-free" electrode system is easily applied to speed shock delivery and optional external pacing. It is designed for general floor and remote areas and its ECG analysis provides rhythm recognition.

Finally, there's the 1700 AED Defibrillator. Like other Automated External Defibrillators, the 1700 is intended to mimics the types of defibrillators used in hospitals, but in a way that allows just about anyone to operate it. It has voice-prompts to guide the user in placing the two electrodes against the bare skin. The device also has a manual override switch to allow it to go from semi-automatic to manual.

All of these models from the ZOLL Company make one things clear. If properly used, these defibrillators have the potential to save thousands of people each year
