“…Respiratory mechanics has been extensively studied during the last century ( RAHN et al, 1946 ; Otis, 1977 ; Collett et al, 1985 ; Bates, 2005 ) with resultant improvement in our understanding of the function of the respiratory system in health and disease states ( MEAD et al, 1955 ; Reinert and Trendelenburg, 1972 ; Dodd et al, 1988 ; Mador, 1991 ). Newfound knowledge of respiratory mechanics has also been applied to different animal models of respiratory disease ( Wanner and Abraham, 1982 ; Wanner et al, 1990 ; Irvin and Bates, 2003 ).…”
