Abstract 166: Brief Compression Only Cardiopulmonary Resuscitation Training Video and Homemade Manikin Improves CPR Skills in Untrained Individuals
Each year in the United States over 300,000 people experience cardiac arrest outside of the hospital. Only about 40% of these people initially receive cardiopulmonary resuscitation (CPR) from a bystander. We assessed the hypothesis that a brief 6-minute internet-based video and homemade manikin would improve compression-only CPR skills.
Methods: This was a parallel-design study with pre and post training evaluations of compression rate, depth, and whether the emergency number (911) was called for help. We recruited subjects currently certified and never certified in CPR. Our video provided compression-only CPR instruction using a homemade manikin reproduced by viewers using common items (towel, t-shirt, and toilet paper roll). Chest compression skills were objectively judged using a Resusci Anne Skillreporter.
Results: Twenty-four subjects were recruited: 12 currently CPR certified and 12 never-certified in CPR. Prior to viewing the video, never-certified subjects had an initial average compression rate per minute of 64.3 +/- 43.6 (mean +/- SD), compression depth of 26.8 +/- 17.1 mm, and 4 subjects (33%) called for help. After viewing the video, never-certified subjects had an increase in average compression rate to 103.9 +/- 20.7 per minute (p=0.006), a non-significant increase in depth to 35.4 +/- 11.1 mm, and 9 subjects called for help (75%). CPR certified subjects had an initial (pre-video) average compression rate of 119.3 +/- 15.2 per minute, compression depth of 46.3 +/- 10.4 mm, and 8 subjects (67%) called for help. After viewing the video, CPR certified subjects had a non-significant increase in average compression rate to 120.7 +/- 12.8 per minute, clinically insignificant compression depth decrease to 43.8 +/- 9.8 mm (p=0.022), and all 12 subjects (100%) called for help. One-factor analysis of variance testing revealed a significantly increased compression rate in never-certified compared with certified subjects (p=0.004).
Conclusions: The use of a brief video and homemade CPR tool can significantly improve chest compression rate and increase calls for help in previously untrained individuals, compared with CPR certified individuals. Compression depths remained overall inadequate (<50 mm) in both the untrained and certified groups.
