To the Editor.—
Dr. Stolfi illustrated an interesting mechanical adjunct to cardiopulmonary resuscitation (CPR) (216:678, 1971).A fundamental concept in CPR instruction is that instrumentation is unnecessary for emergency resuscitation techniques. Utilization of a mechanical device would decrease the number of persons qualified to offer CPR (qualified by virtue of possession of such a device) as well as limit the number of patients whose body build would be compatible with a specific device. Children or patients with unusual jaw structure would be examples. One would wonder about potential air leakage around and within the stainless steel collapsible and folding device. One would wonder if any such device could have universal application. If not, in what percentage of the population would such a device be appropriate?A well-trained person can offer closed chest cardiac massage and respiratory support without the benefit of a nose clip.
