Artificial respiration is an important part of cardiorespiratory resuscitation. Mouth-to-mouth or mouth-to-nose breathing, or both, are considered the most effective methods if special equipment is not available. Instances of resuscitation, which can be analyzed on purely medical grounds, are described in the Bible. On the basis of early postbiblical literature it is shown that the prophet Elisha, contrary to general belief, was not the first to use mouth-to-mouth breathing, and that the origins of artificial respiration are in ancient Hebrew folkloric medicine.
