A novel and yet untested memory aid has anecdotally been proposed for aiding practitioners in complying with American Heart Association (AHA) cardiopulmonary resuscitation (CPR) compression rate guidelines (at least 100 compressions per minute).
This study investigates how subjects using this memory aid adhered to current CPR guidelines in the short and long term.
A prospective observational study was conducted with medical providers certified in 2005 AHA guideline CPR. Subjects were randomly paired and alternated administering CPR compressions on a mannequin during a standardized cardiac arrest scenario. While performing compressions, subjects listened to a digital recording of the Bee Gees song "Stayin' Alive," and were asked to time compressions to the musical beat. After at least 5 weeks, the participants were retested without directly listening to the recorded music. Attitudinal views were gathered using a post-session questionnaire.
Fifteen subjects (mean age 29.3 years, 66.7% resident physicians and 80% male) were enrolled. The mean compression rate during the primary assessment (with music) was 109.1, and during the secondary assessment (without music) the rate was 113.2. Mean CPR compression rates did not vary by training level, CPR experience, or time to secondary assessment. Subjects felt that utilizing the music improved their ability to provide CPR and they felt more confident in performing CPR.
Medical providers trained to use a novel musical memory aid effectively maintained AHA guideline CPR compression rates initially and in long-term follow-up. Subjects felt that the aid improved their technical abilities and confidence in providing CPR.
有人提出了一种新颖但未经测试的记忆辅助工具，据传闻它有助于从业者遵守美国心脏协会（AHA）的心肺复苏（CPR）按压速率指南（每分钟至少100次按压）。
本研究调查使用这种记忆辅助工具的受试者在短期和长期内如何遵守当前的心肺复苏指南。
对获得2005年AHA心肺复苏指南认证的医疗服务提供者进行了一项前瞻性观察性研究。受试者被随机配对，并在标准化心脏骤停场景中轮流对人体模型进行心肺复苏按压。在进行按压时，受试者收听比吉斯乐队歌曲《活着》的数字录音，并被要求随着音乐节拍进行按压计时。至少5周后，对参与者进行重新测试，且不再直接收听录制的音乐。通过会后问卷收集态度观点。
招募了15名受试者（平均年龄29.3岁，66.7%为住院医师，80%为男性）。初次评估（有音乐）期间的平均按压速率为109.1，二次评估（无音乐）期间的速率为113.2。平均心肺复苏按压速率不因培训水平、心肺复苏经验或二次评估时间而有所不同。受试者认为利用音乐提高了他们进行心肺复苏的能力，并且他们在进行心肺复苏时更有信心。
接受培训使用这种新颖音乐记忆辅助工具的医疗服务提供者在最初和长期随访中有效地维持了AHA心肺复苏指南的按压速率。受试者认为这种辅助工具提高了他们的技术能力以及进行心肺复苏的信心。
