Sponsor delivery record (1)
Enrollment hit target: the share of this sponsor's lead-sponsored trials whose actual enrollment reached the planned enrollment. On time: the share whose actual primary completion date was no later than the planned date. Each share counts only trials where we observed an estimated figure before the actual one, and n is that number of trials. Below 5 trials the count is shown as a fraction, not a percentage.
| Enrollment | Timeline |

| Brand Name: ZOLL Product Name: Powerheart G5 AED Model/Catalog Number: (1) G5A-00A, (2) G5A-01A, (3) G5A-02A, (4) G5A-03A, (5) G5A-19A, (6) G5A-80A, (7) G5A-80A-TSO. Software Version: NA Product Description: The Powerheart G5 automated external defibrillator (AED) is designed for treating life-threatening heart beat irregularities, such as ventricular fibrillation, that cause Sudden Cardiac Arrest (SCA). There are two models available fully automatic and semi-automatic. After the defibrillations pads are applied to the patient, the fully automatic model evaluates the heart rhythm and, if a shockable rhythm is detected, delivers a shock without any rescuer assistance. The semi-automatic model evaluates the heart rhythm and requires the rescuer to press the shock button if a shockable rhythm is detected. Both models have voice and text instructions that guide the rescuer through the entire defibrillation process. Note: Not all configurations described in this document are available in all areas. | Class II | 2025-02-13 |
