title: An evaluation of some mechanical resuscitators for use in the ambulance service.
abstract: The requirements for a mechanical resuscitator intended for use in the ambulance service are set out in detail. Seven resuscitators in current use (4 volume-cycled, 3 pressure-cycled) were subjected to a series of tests of efficiency, reliability, and robustness and their portability and foolproof qualities were evaluated. Although 3 of the machines met the functional requirements for resuscitation, only one, the volume-cycled Pneupac, fulfilled all the criteria laid down.
