A new method to increase the quality of cardiopulmonary resuscitation in hospital

In order to ensure that high-quality cardio-pulmonary-resuscitation (CPR) is performed, many kinds of feedback devices have been developed that are helpful for achieving correct chest compression (CC) in manikin studies. However, the mattress compression depth (MCD) can cause overestimation of chest compression depth (CCD) during CPR using a feedback device. Herein, we propose a new method using a vinyl cover that encloses the foam mattress and is compressed by vacuum pump just before performing CPR, which could increase the performance of CCs during CPR. For the verification, nine CPR providers performed CCs on manikin lying on five different surfaces, with the manikin's visual feedback system as follows: (surface A) no mattress on a bed frame, (surface B) on a foam mattress laid on a bed frame, (surface C) Surface B with backboard, (surface D) on a compressed foam mattress with a vacuum pump laid on a bed frame, and (surface E) Surface D with backboard. Two accelerometers were used to measure the mattress compression and chest compression depths through double integration and subtraction of the acceleration signals. The mean (s.d.) of MCD was 5.7mm (0.6mm) on surface A, .14.9mm (1.4mm) on surface B, 14.0mm (1.3mm) on surface C, 7.0mm (0.6mm) on surface D, and 7.0mm (0.7mm) on surface E. The MCD decreased from 14.9mm (1.4mm) on Surface B to 7.0mm (0.6mm) on Surface D (p <; 0.001), which did not differ from the MCD on Surface A (p=0.13). Use of a mattress compression cover and a vacuum pump appears to increase the stiffness of the mattress. This method could decrease the mattress compression depth and help correct chest compression in hospitals.
