I was recently having a discussion with one of the agencies in charge of training lifeguards in our area. For years, lifeguards have put patients in a lateral position when performing Artificial Respirtation on a near drowning patient. The agency was told by one of their advisors that lateral AR (out of hospital) is not as effective as supine resuscitation do to limitations of chest expansion. However, their reasoning for using the lateral position (as stated by the agency) is because of the high rate of vomitting following a near drowning experience. Could someone please provide accurate information in this regard (articles relating to lateral ventilation would be greatly appreciated)? Thanks.
