title: Body plethysmographic measurements in children with an accompanying adult.
abstract: If a child refuses to enter the body plethysmograph, he may be accompanied by a relative or an assistant. Measurements are possible after the companion has stopped breathing and box pressure has stabilized. The reliability of this procedure is proved by a comparative examination of 25 children performed without and with a companion.
