In six dogs with oleic acid respiratory failure, we measured Pes and Ppl in the uppermost, middle, and most dependent lung regions. Each dog was studied at positive end-expiratory pressure (PEEP) of 5 and 15 cm H2O and three levels of tidal volume (Vt; low, medium, and high). For each PEEP\u2013Vt combination, we obtained a computed tomographic (CT) scan at end-inspiration and end-expiration. The variations of Ppl and Pes pressures were correlated (r = 0.86 \u00b1 0.07, p &amp;lt; 0.0001), as was the vertical gradient of transpulmonary (Pl) and superimposed pressure (r = 0.92, p &amp;lt; 0.0001). Recruitment proceeded continuously along the entire volume\u2013pressure curve. Estimated threshold opening pressures were normally distributed (mode = 20 to 25 cm H2O). The amount of end-expiratory collapse at the same PEEP and Pl was significantly lower when ventilation was performed at high Vt. End-inspiratory and end-expiratory collapse were highly correlated (r = 0.86, p &amp;lt; 0.0001), suggesting that as more tissue is recruited at end-inspiration, more remains recruited at end-expiration. When superimposed pressure exceeded applied airway pressure (Paw), collapse significantly increased.<\/jats:p>","DOI":"10.1164\/ajrccm.164.1.2007010","type":"journal-article","created":{"date-parts":[[2013,4,4]],"date-time":"2013-04-04T14:46:16Z","timestamp":1365086776000},"page":"122-130","source":"Crossref","is-referenced-by-count":394,"title":["Recruitment
