Abstract
Assessment of the esophageal pressure technique for measuring dynamic lung compliance (Cdyn) showed that accurate results were obtained in only 5 of 15 studies of sick intubated infants, whereas they were obtained in 6 of 6 studies of convalescent nonintubated infants. In sick infants, inaccuracy was due to large variations in esophageal pressure change (APes) at different esophageal depths and difficulties validating Pes using the occlusion test. Methods of assessing lung stiffness that depend on the measurement of esophageal pressure are unreliable and should not be used in sick intubated infants.Keywords
