... Branson ventilation. Recent work suggests that the work of breathing postextubation may actually increase compared with work of breathing through the ET tube, raising questions about the conclusion of the study ... advantages of ATC over PSV are reduced work of breathing as patient demand varies, preservation of a normal, variable breathing pattern, and improved synchr...
