In a cardiac emergency, the intervener is not always sure whether they are pressing hard enough or fast enough. The ZOLL AED Plus corrects this hesitation with the Real CPR Help function, which monitors compressions in real-time and uses voice and on-screen prompts to indicate if more pressure is needed or if the pace should be changed. The shock uses ZOLL's Rectilinear Biphasic technology.

• CPR-D-padz electrodes are a single piece, with the two contact areas already positioned to prevent placement errors
• These same electrodes last for 5 years, so replacement is infrequent
• The 7-year warranty covers parts and labor
