Life-supporting first aid self-training.

The authors studied the acquisition of life-supporting first aid knowledge and skills by 230 lay people in self-training group instruction without qualified first aid instructors and self-training at home. The self-training course consisted of audiotape-recorded instructions, flipover charts, an instruction booklet, first aid materials and a "Resusci Anne" training mannikin. The same instruction booklet and first aid materials were used for self-training at home. The two teaching systems were equally effective in providing theoretical first aid knowledge, but the course proved superior in teaching practical skills.
