Brief summary
The investigators conducted a randomized, controlled, single-blinded study of patients undergoing CPR for cardiac arrest in the mixed medical-surgical ICUs of four academic teaching hospitals in Tehran, Iran from June 1 to October 31, 2014. Patients were randomized to receive CPR with either standard manual compression, or compression with real-time audiovisual feedback using the Cardio First Angel™ device.
Detailed description
The investigators sought to determine if the addition of a CPR feedback device to routine manual CPR would impact the quality and consistency of chest compression and patient survival. We conducted a randomized, controlled, single-blinded study of patients undergoing CPR for cardiac arrest in the mixed medical-surgical ICUs of four academic teaching hospitals. Patients were randomized to receive either standard manual CPR or CPR using the Cardio First Angel™ (CFA; INOTECH, Nubberg, Germany) feedback device. Recorded variables included return of spontaneous circulation, adherence to CPR guidelines and quality of CPR, nurse satisfaction and CPR associated morbidity.
Interventions
DEVICECompression with Feedback
Patients in the intervention group received CPR in accordance to published guidelines using the CFA device per manufacturer instructions. The Cardio First Angel™ (CFA; INOTECH, Nubberg, Germany) is a lightweight device that consists of three components . Application of400 ± 30 Newtons of force (41 kg or 90 lb of pressure), which correlates toa sternum compression depth of 50-60 mm, is followed by an audible click sound to alert the rescuer to cease compression. The click sound is also audible upon spring decompression alerting the rescuer to resume compression. The device does not require an electrical power supply.
OTHERStandard chest compression
CPR in accordance with published international guidelines using standard manual chest compression.
