Abstract P52: Resuscitation Blanket During CPR for “Hands-on” Defibrillation
Background Uninterrupted chest compression has been recognized as a important factor for improving cardiopulmonary resuscitation (CPR) outcomes. We therefore introduced a resuscitation blanket made from insulating material which allows for uninterrupted chest compressions during shock delivery. We hypothesized that the resuscitation blanket used during CPR is safe, feasible and efficient to protect the rescuer from the risk of receiving current during defibrillation and therefore allowing performance of continuous chest compressions during CPR.
Methods Fifteen pigs weighing between 22–40 kg were investigated. CPR was performed with the interposition of the blanket between the rescuer’s hands and the chest of the animal. Defibrillation voltage and current below and above the blanket were measured. Hemodynamics, including coronary perfusion pressure (CPP), end-tidal CO2 (EtCO2) and 50% successful defibrillation threshold (DFT50) were investigated. The results were compared to those measured during CPR without the blanket.
Results The voltage measured above the blanket was 42.0V, 56.6V and 105V and mean leakage current above the blanket was 1.1 μA, 1.4 μA and 3.3 μA, respectively for 150, 200 and 360 J defibrillation. The average CPP and EtCO2 in the animals during chest compression with the resuscitation blanket were not significantly different compared to those measured without the blanket. However, when the blanket was not utilized, CPP decreased to near 0 (P<0.05) during the 15-second hands-off interruption prior to defibrillation. The DFT50 was significantly lower when the blanket was used.
Conclusion The resuscitation blanket allows for continuous precordial compression without interruption for delivering a defibrillation shock. It therefore minimizes the hands-off interruptions of chest compression and improves hemodynamics prior to delivering of an electrical shock and ultimately increases the defibrillation success.
