The purpose of this study was to analyse the effects of sitting, supine and laterals positions on arterial oxygen tension (Pa02) and arterial carbon dioxide tension (PaC02), in 22 adults patients, carier of some pulmonary bilateral disfunction, in recent post-operative cardiac surgery. The diagnosis of the pulmonary disfunction was done through radiographic torax evaluation. The patients stayed during 15 minutes in each position and after this, the arterial blood gases were measured. Based on Friedman test and Multiple Comparation test (a — 0,05), no significant changes in Pa02 and PaC02 were noted.
