Implementation of a mechanical chest compression device

High-quality chest compressions are a key factor in survival from out-of-hospital cardiac arrest (OHCA). Yet, it is widely accepted that the technique used during CPR is frequently inadequate and often provides only 30% of normal perfusion. Several studies have advocated the use of mechanical chest compression devices in the pre-hospital setting; however, there is little definitive information relating to the process and issues associated with implementing such a device into a large urban ambulance system.

Undertaken in Minnesota (United States of America), this study examines the implementation of a mechanical chest compression device (LUCAS™1) in the management of OHCA within Allina Health EMS. The study began with a four-month evaluation pilot. Devices were placed on a limited number of vehicles with crews who were trained to use the device. Feedback from the pilot provided positive results and the LUCAS™1 was subsequently rolled out across the service.

A retrospective case-series of device-eligible OHCAs was carried out between May 2008 and June 2010, with clinical data being extracted from electronic patient care records (ePCR). In addition, qualitative data about staff's experiences with this particular device were obtained from the North American LUCAS™ Evaluation (NALE) between November 2008 and June 2009, via a web-based survey.
