Compliant surfaces beneath a casualty diminish the quality of cardiopulmonary resuscitation (CPR) in clinical environments. To examine this issue in a sporting environment, we assessed chest compression quality and rescuer exertion upon compliant sports safety matting.
Twenty-seven advanced life support providers volunteered (13 male/14 female; mass = 79.0 ± 12.5 kg; stature = 1.77 ± 0.09 m). Participants performed 5 × 2 min, randomized bouts of continuous chest compressions on a mannequin, upon five surfaces: solid floor; low-compliance matting; low-compliance matting with a backboard; high-compliance matting; high-compliance matting with a backboard. Measures included chest compression depth and rate, percentage of adequate compressions, and rescuer heart rate and perceived exertion.
Chest compression depth and rate were significantly lower upon high-compliance matting relative to other surfaces (p<0.05). The percentage of adequate compressions (depth ≥50 mm) was lowest upon high-compliance matting (40 ± 39%) versus low-compliance matting (60 ± 36%) and low-compliance matting with a backboard (59 ± 39%). Perceived exertion was significantly greater upon high-compliance matting versus floor, low-compliance matting, and low-compliance matting with a backboard (p<0.05).
Providers of CPR should be alerted to the detrimental effects of compliant safety matting in a sporting environment and prepare to alter the targeted compression depth and rescuer rotation intervals accordingly.
伤员下方的顺应性表面会降低临床环境下心肺复苏(CPR)的质量。为了在运动环境中研究这个问题,我们评估了顺应性运动安全垫上的胸外按压质量和施救者的用力情况。
27 名高级生命支持提供者自愿参与(13 名男性/14 名女性;体重=79.0±12.5kg;身高=1.77±0.09m)。参与者在模拟人上进行了 5 次 2 分钟、随机的连续胸外按压回合,分别在 5 种表面上进行:实心地板;低顺应性垫;带背板的低顺应性垫;高顺应性垫;带背板的高顺应性垫。测量指标包括胸外按压深度和频率、足够按压的百分比以及施救者的心率和感知用力情况。
与其他表面相比,高顺应性垫上的胸外按压深度和频率明显较低(p<0.05)。高顺应性垫上的足够按压百分比(深度≥50mm)最低(40±39%),低于低顺应性垫(60±36%)和带背板的低顺应性垫(59±39%)。与地板、低顺应性垫和带背板的低顺应性垫相比,高顺应性垫上的感知用力明显更大(p<0.05)。
CPR 的提供者应该意识到顺应性安全垫在运动环境中的不利影响,并准备相应地调整目标按压深度和施救者轮换间隔。
