RESUMEN

Objective To observe the effect of air mattress bed on the quality of chest compression during cardiopulmonary resuscitation (CPR). Methods This was a self-controlled study and included twenty formally CPR-trained doctors. According to the 2015 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care, chest compression was randomly tested on a manikin for two minutes in A, B, C group. Group A was tested in ordinary bed, group B was compress in air mattress and hard backboard, and group C was tested in air mattress bed. There was a ten minutes rest between each compression. All compression data, including compression rate, depth, incomplete recoil and shallow number, were collected via real-time feedback device. Statistical analysis was performed using SPSS 22.0. Multiple groups were compared with One-way ANOVA and within groups were compared with t test. The enumeration data was analyzed by chi-square test. Results There was no statistically significant difference between groups in mean chest compression rates (107.9±5.1 vs. 107.7±4.56 vs. 109.7±4.86, P=0.6). Mean compression depth was significantly better in group A and B than in group C [(53.45±2.04) mm and (52.65±2.13) mm vs. (48.45±1.36) mm, all P<0.05)]. The number of shallow compression in group C was significantly higher than those in group A and B [(97.3±23.4) vs. (23.6±19.3) and (35.3±33.9), all P<0.05)]. The retention rates in group A was better than those in group B and C [(58.43±4.17%) vs. (62.51±4.37)% and (62.63±4.22)%, all P<0.05]. The compression depth of group C in the second minute was significantly less than that in the first minute (46.45±1.43 mm vs. 50.05±1.64 mm, P<0.05), and the number of shallow compression was more than the first minute (62.1±16.4 vs. 35.3±8.5, P<0.05). Significant difference in accuracy was observed among the three groups (33.64% vs. 28.66% vs. 19.24%, P<0.05). Conclusions The use of air mattress bed in CPR has a significant impact on the quality of manual chest compression. Eliminating the elasticity of air mattress bed would effectively improve the quality of chest compressions.
