Development of a diagnostic feedback device to assess neonatal cardiopulmonary resuscitation chest compression performance

Neonatal cardiopulmonary resuscitation (NCPR) is an important intervention to save the lives of newborns who suffer from cardiac and respiratory arrest. Despite its importance there is a dearth of NCPR research and no commercially available feedback device suitable for use during NCPR. The aim of this study is to develop a diagnostic feedback device in the form of a patch placed on the infant's chest. The diagnostic feedback patch measures both the compression depth and force during NCPR, while giving audio-visual feedback according to current NCPR guidelines. The patch was systematically evaluated by conducting a series of hardware validation tests to assess the depth, force and feedback performance. The average errors in the depth and force were found to be 10.8% and 12.4%, respectively, with maximal errors below 20.7% and 24.1%. These results along with positive outcome of the feedback test suggest that the device is reliable on a hardware level and is suitable for further evaluation in a clinical setting.
