Discussion of article on comparative studies of new push-pull methods for pole-top resuscitation

QUESTIONS HAVE BEEN RAISED, mostly by safety engineers of electric power supply companies, as to whether the basic principle of the recently accepted Holger-Nielsen push-pull prone method of artificial respiration is applicable as an advantageous revision of the pole-top method of artificial respiration. As a result of the authors´ interest in the general problem of artificial respiration, there now is available for study and analysis, data based on well-planned and courageously executed laboratory tests. However, when a change from the time-proved practice is contemplated, serious consideration must be given to two factors of primary importance, namely, whether the present practice is inadequate, either from an application or efficiency viewpoint, or whether the present practice can be replaced by another which is more effective without greatly sacrificing any advantages of the one being replaced.
