<P> The technique is also important in possibly preventing insufflation of gas into the stomach . A study concluded that appropriate application of cricoid pressure prevents gastric gas insufflation during airway management via mask up to 40 cm H2O PIP in infants and children . An additional benefit of cricoid pressure occurs in paralyzed patients in whom gastric insufflation occurs at lower inflation pressures . </P> <P> Anterior cricoid pressure was considered the standard of care during Rapid Sequence Intubation for many years . The American Heart Association, until the 2010 science update, advocated the use of cricoid pressure during resuscitation using a BVM, and during emergent oral endotracheal intubation; effective 2010, use of Cricoid Pressure is now discouraged during the routine intubation of cardiac arrest victims . </P> <P> Cricoid pressure may frequently be applied incorrectly . Cricoid pressure may frequently displace the esophagus laterally, instead of compressing it as described by Sellick . Several studies demonstrate some degree of glottic compression reduction in tidal volume and increase in peak pressures . </P> <P> The initial proposal of cricoid pressure as a useful clinical procedure, its subsequent adoption as the lynchpin of patient safety, and its current decline into disfavor represents a classic example of the need for evidence - based medicine, and the evolution of medical practice . </P>
