Realtime detection of spontaneous circulation in humans during cardiopulmonary resuscitation using a continuous hands-free carotid Doppler: a pilot study.

ABSTRACT:

Background

The resuscitation society calls for precision-guided cardiopulmonary resuscitation (CPR), as current methods are inaccurate and time-consuming. RescueDoppler, a novel hands-free Doppler ultrasound system, continuously measures carotid blood flow during CPR. This pilot study assessed its performance, safety, and ability to detect chest compression-generated blood flow, spontaneous circulation, and return of spontaneous circulation (ROSC).

Method

We investigated RescueDoppler in adult cardiac arrest patients at two centres, in-hospital (IHCA) and out-of-hospital (OHCA). The cardiac arrest team placed the RescueDoppler probe over the left common carotid artery with a self-adhesive patch, collecting blinded data during CPR. Data were later interpreted and time-synchro
