Catalina Island's Casino Point is a popular scuba diving site and is located 11.6 nautical miles from the University of Southern California Catalina Hyperbaric Chamber. We sought to determine the best method of providing high-performance CPR during a dive emergency, comparing manual cardiopulmonary resuscitation (CPR) with 2 mechanical compression devices during a simulated boat transport.
This study was performed on a Los Angeles County Lifeguard rescue boat using 3 manikins and comparing 3 arms: 1) manual compressions with 2 rescuers, 2) mechanical CPR with the Autopulse (ZOLL, Chelmsford, MA), and 3) mechanical CPR with the LUCAS III (Stryker, Kalamazoo, WI). CPR data were collected using ZOLL Stat Padz with an accelerometer connected to ZOLL X Series monitor/defibrillators. The manikins were filmed using mounted cameras. Data were reviewed using ZOLL Case Review.
In video footage, all 3 arms appeared to provide high-performance CPR during the 30-minute transport. The compression fractions for manual CPR, the Autopulse, and the LUCAS were 99.57%, 95.51%, and 98.4%, respectively. Engine noise (94.6-101.3 dB) prevented the manual arm from hearing their audio prompts, and motion caused significant artifact on the accelerometers.
High-performance CPR can successfully be performed on a rescue boat by either manual or mechanical methods. Mechanical CPR offered many logistical advantages.
卡特琳娜岛的 Casino Point 是一个很受欢迎的水肺潜水地点，距离南加州大学卡特琳娜高压舱 11.6 海里。我们旨在确定在潜水紧急情况下提供高性能心肺复苏术的最佳方法，比较手动心肺复苏术（CPR）与 2 种机械压缩设备在模拟船只运输中的效果。
这项研究在洛杉矶县救生员救援船上进行，使用 3 个人体模型，并比较 3 种方法：1）由 2 名救援人员进行手动按压，2）使用 Autopulse（ZOLL，马萨诸塞州切姆斯福德）进行机械 CPR，3）使用 LUCAS III（Stryker，密歇根州卡拉马祖）进行机械 CPR。使用连接到 ZOLL X 系列监测除颤器的加速度计的 ZOLL Stat Padz 收集 CPR 数据。使用安装的摄像头拍摄人体模型。使用 ZOLL Case Review 查看数据。
在视频中，所有 3 种方法在 30 分钟的运输过程中似乎都提供了高性能的 CPR。手动 CPR、Autopulse 和 LUCAS 的压缩分数分别为 99.57%、95.51%和 98.4%。发动机噪音（94.6-101.3 dB）阻止了手动方法听取其音频提示，运动导致加速度计上出现明显的干扰。
通过手动或机械方法都可以在救援船上成功进行高性能心肺复苏术。机械 CPR 具有许多后勤优势。
