Abstract
We evaluated cardiopulmonary resuscitation CPR performed by persons with no previous experience on a resuscitation dummy Subjects were randomized into four groups one of which had no instruction The other three groups were instructed for 3 min in mock CPR by a supervisor using a telephone a video link or directly in person They were compared with a group which had had previous CPR training The main outcome measures were the number of correct ventilations chest compressions and compressions with correct hand position Video link instruction was associated with significantly higher median scores for all three outcome measurements P Under 0 05 whereas telephone instruction and previous CPR training were associated with higher scores on only one namely ventilations P Under 0 05 Video link instruction was comparable with direct observer instruction There was no significant difference between previously trained subjects and the intervention groups Video link instruction can produce significant improvements in the quality of CPR in mock resuscitations for persons with no resuscitation training
