Abstract
BackgroundCardiopulmonary resuscitation (CPR) training has traditionally involved classroom-based courses or, more recently, home-based video self-instruction. These methods typically require preparation and purchase fee; which can dissuade many potential bystanders from receiving training. This study aimed to evaluate the effectiveness of teaching compression-only CPR to previously untrained individuals using our 6-min online CPR training video and skills practice on a homemade mannequin, reproduced by viewers with commonly available items (towel, toilet paper roll, t-shirt).MethodsParticipants viewed the training video and practiced with the homemade mannequin. This was a parallel-design study with pre and post training evaluations of CPR skills (compression rate, depth, hand position, release), and hands-off time (time without compressions). CPR skills were evaluated using a sensor-equipped mannequin and two blinded CPR experts observed testing of participants.ResultsTwenty-four participants were included: 12 never-trained and 12 currently certified in CPR. Comparing pre and post training, the never-trained group had improvements in average compression rate per minute (64.3 to 103.9, p = 0.006), compressions with correct hand position in 1 min (8.3 to 54.3, p = 0.002), and correct compression release in 1 min (21.2 to 76.3, p < 0.001). The CPR-certified group had adequate pre and post-test compression rates (>100/min), but an improved number of compressions with correct release (53.5 to 94.7, p < 0.001). Both groups had significantly reduced hands-off time after training. Achieving adequate compression depths (>50 mm) remained problematic in both groups. Comparisons made between groups indicated significant improvements in compression depth, hand position, and hands-off time in never-trained compared to CPR-certified participants. Inter-rater agreement values were also calculated between the CPR experts and sensor-equipped mannequin.ConclusionsA brief internet-based video coupled with skill practice on a homemade mannequin improved compression-only CPR skills, especially in the previously untrained participants. This training method allows for widespread compression-only CPR training with a tactile learning component, without fees or advance preparation.
Highlights
Cardiopulmonary resuscitation (CPR) training has traditionally involved classroom-based courses or, more recently, home-based video self-instruction
Significant improvements were seen in compression rate, correct hand position, correct compression release/recoil, and hands off time
A statistically significant difference remained after training, both groups performed at adequate compression rates (>100 per minute, per American Heart Association (AHA) guidelines)
Summary
Cardiopulmonary resuscitation (CPR) training has traditionally involved classroom-based courses or, more recently, home-based video self-instruction. These methods typically require preparation and purchase fee; which can dissuade many potential bystanders from receiving training. Cardiopulmonary resuscitation (CPR) initiated by bystanders can significantly improve survival outcomes, only 46.1% of cardiac arrest victims initially receive CPR from a bystander [1,2,3]. Abbreviated training methods providing video instruction and practice on an inflatable mannequin have proven to be effective [11,12,13,14,15]. While instructor-led training is recommended, European guidelines suggest that self-instruction with hands-on practice appears to be an “effective alternative” [11]
