No study has examined the effectiveness of backboards and air deflation for achieving adequate chest compression (CC) depth on air mattresses with the typical configurations seen in intensive care units. To determine this efficacy, we measured mattress compression depth (MCD, mm) on these surfaces using dual accelerometers. Eight cardiopulmonary resuscitation providers performed CCs on manikins lying on 4 different surfaces using a visual feedback system. The surfaces were as follows: A, a bed frame; B, a deflated air mattress placed on top of a foam mattress laid on a bed frame; C, a typical air mattress configuration with an inflated air mattress placed on a foam mattress laid on a bed frame; and D, C with a backboard. Deflation of the air mattress decreased MCD significantly (B; 14.74 ± 1.36 vs C; 30.16 ± 3.96, P < 0.001). The use of a backboard also decreased MCD (C; 30.16 ± 3.96 vs D; 25.46 ± 2.89, P = 0.002). However, deflation of the air mattress decreased MCD more than use of a backboard (B; 14.74 ± 1.36 vs D; 25.46 ± 2.89, P = 0.002). The use of a both a backboard and a deflated air mattress in this configuration reduces MCD and thus helps achieve accurate CC depth during cardiopulmonary resuscitation.
尚无研究检查背板和空气放气在重症监护病房中常见的典型气垫床配置下实现充分的胸部按压 (CC) 深度的效果。为了确定这种效果,我们使用双加速度计测量这些表面上的床垫压缩深度 (MCD,mm)。八名心肺复苏提供者使用视觉反馈系统对躺在四个不同表面上的模拟人进行 CC。这些表面如下:A,床架;B,放置在床架上的泡沫床垫上的放气气垫;C,充气气垫放置在床架上的泡沫床垫上的典型气垫配置;D,C 带有背板。气垫的放气显着降低了 MCD(B;14.74 ± 1.36 与 C;30.16 ± 3.96,P < 0.001)。使用背板也降低了 MCD(C;30.16 ± 3.96 与 D;25.46 ± 2.89,P = 0.002)。然而,气垫的放气降低 MCD 的效果大于使用背板(B;14.74 ± 1.36 与 D;25.46 ± 2.89,P = 0.002)。在这种配置中同时使用背板和放气气垫会降低 MCD,从而有助于在心肺复苏期间实现准确的 CC 深度。
