Comparative studies of new push-pull methods for pole-top resuscitation

All push-pull pole-top methods of resuscitation, evaluated on five apneic subjects, proved 1½ times as effective for pulmonary ventilation as the standard pole-top method. The double-rock push-pull seems best for several reasons. A discussion by E. W. Oesterreich questions the advisability of adopting this new system unless it can be proved conclusively either that the present method is inadequate or the new method more effective and that it does not sacrifice any advantages now obtained.
