Hands-off ratio were lower for mechanical CPR both before (p =0.016) and during transport (p =0.002).įor manual CPR, Time without chest compressions during transport and compression rate was lower due to difficult conditions. Quality of cardiopulmonary resuscitation before and during transport in out-of hospital cardiac arrest Īdult patients over 18 years of age suffering from non-traumatic OHCA for all causes and received CPR before and during transportation.Ĭhest compression and ventilation rates, hands-off ratio (time without compressions divided by total CPR time). Working conditions for standard CPR in ambulance transport is undesirable. Mechanical CPR adhered more closely to ERC guidelines. Randomized, cross-over, out-of-hospital study comparing between three type of CPR at cardiac arrests sites and during transportation.Ĭompression depth, frequency, compression – decompression ratio based on European Resuscitation Council Guidelines (ERC).Ĭompression depth, frequency and compression ratio in mechanical CPR device were within recommended guidelines during ambulance transports as compared to other 2 groups. Quality of mechanical, manual standard and active compression-decompression CPR on the arrest site and during transport in a manikin model ģ6 runs conducted on a manikin which runs are split between 3 groups. The device is able to deliver higher number of effective and consistent compression at correct position as compared to manual CPR.ĩ7% rate for the device remains valid for different environment settings while 37% rate for manual CPR varied in different settings. Thumper provided pre-defined correct compressions for 97% of the runs (n = 70) while manual compressions were performed correctly 37% of the runs (n = 27). Prospective observational study comparing between both types of CPR in different environment settings such as vehicle type, road conditions, vehicle speed.Ĭompression adequacy (defined as 1.5 to 2 inches in depth, 60 compressions per min +/- 10% and correct hand position). The recovery rate of Thumper cardiopulmonary resuscitator is more conducive to save manpower and obtain better metabolic effect, which is worthy of clinical promotion and application.Comparing CPR ambulance transport: Manual versus Mechanical methods ġ44 simulated runs conducted on a manikin. In the process of emergency rescue, Thumper cardiopulmonary resuscitator is more successful than bare-handed CPR. The PaO 2 and SaO 2 in the Thumper CPR group were significantly higher than those in the bare-handed CPR group.
There was no significant difference in blood gas index between the two groups after 5 minutes of recovery. Compared with the bare-handed CPR group, the ROSC rate in the Thumper CPR group was significantly increased, but there was no significant difference in return of spontaneous breathing rate.
There was no significant difference in gender, age and cardiac arrest (CA) causes between the two groups. Return of spontaneous circulation (ROSC) and return of spontaneous breathing, and blood gas analysis indexes of recovery for 5 minutes and 15 minutes were collected. Seventy patients who underwent CPR using the Thumper cardiopulmonary resuscitator were included in the Thumper CPR group 80 patients who underwent manual hand-held CPR were included in the bare-handed CPR group. CPR adult patients admitted to the Emergency Room of First Hospital of Qinhuangdao in Hebei Province from January 2015 to January 2017 were enrolled. To objectively and standardly compare the bare-handed CPR and Thumper cardiopulmonary resuscitation CPR recovery effect based on cardiopulmonary resuscitation (CPR) Utstein model.Ī retrospective study was conducted.
