The quality of chest compression (CC) is influenced by the surface supporting the patient. The present study compared chest compression depth with and without a rigid backboard on an operating table with a pressure-distributing mattress. We hypothesized that the presence of a backboard would result in an increased depth of chest compression on the operating table with a pressure-distributing mattress. In a randomized crossover trial, we simulated in-hospital cardiac arrest in a Resusci Anne SkillReporter model placed on a standard operating table with a 6-cm-thick pressure-distributing mattress. A total of 25 male doctors performed CC 30 times, with or without the rigid backboard. Mean chest compression depth increased from 4.9 ± 0.4 to 5.4 ± 0.3 mm (P < 0.0001) when a backboard was present. Mean proportion of compressions >50 mm increased significantly with the presence of a backboard (53.6% ± 32.3%-81.8% ± 15.0%, P < 0.0001). Applying a backboard significantly increased CC depth during cardiopulmonary resuscitation of a manikin model on an operating table with a pressure-distributing mattress.
胸外按压（CC）的质量受到支撑患者的表面的影响。本研究比较了在带有压力分布床垫的手术台上使用和不使用硬板时的胸外按压深度。我们假设使用背板会导致在带有压力分布床垫的手术台上进行胸外按压的深度增加。在一项随机交叉试验中，我们在标准手术台上使用 Resusci Anne SkillReporter 模型模拟院内心搏骤停，该手术台配有 6 厘米厚的压力分布床垫。总共 25 名男性医生进行了 30 次 CC，有和没有使用硬板。当存在背板时，平均胸外按压深度从 4.9 ± 0.4 毫米增加到 5.4 ± 0.3 毫米（P < 0.0001）。当存在背板时，按压深度大于 50 毫米的比例显著增加（53.6% ± 32.3%-81.8% ± 15.0%，P < 0.0001）。在带有压力分布床垫的手术台上使用背板可显著增加心肺复苏期间对男性模型的 CC 深度。
