title: Automatic physiotherapy instruction.
abstract: An automatic tape-recorder system constructed to provide intermittent physiotherapy instruction for postoperative patients is described. Eighty patients, who had been given nitrous oxide and relaxant anaesthesia, were observed during the first 4 postoperative hours. Those who had received pre-operative physiotherapy instruction, responded well. They followed the programme and blood-gas analysis demonstrated elevations of arterial blood oxygen tensions after they had followed the instructions. The system can be recommended as a supplement to physiotherapy in a busy post-operative ward. It also protects the patient from unpleasant noises in the environment.
