Audiovisual compression feedback
DeviceThe Cardio First Angel™ (CFA; INOTECH, Nubberg, Germany) is a handheld device consisting of three components. The rescuer-side has a red palm-sized push-button with a pictogram illustrating proper use. The center unit is composed of a stable plastic base containing an arrangement of springs, and the patient-side consists of liquid-absorbent polyurethane foam. Application of 400 ± 30 Newtons of force results in an audible click alerting the rescuer to cease compression, and an additional click on decompression alerts the rescuer to resume compression.
