['To prospectively evaluate the effects of compressive vests on the pulmonary function of infants with thoracic burn scars.', 'Between April 2000 and October 2005, all infants aged 2 years or less and all those aged between 2 and 3 years if they had concomitant pulmonary pathology, who were in need of a compressive vest for the treatment of burn scars to the thorax, underwent comparative pulmonary function testing under sedation with the vest closed and then opened.', 'Of the 23 infants who met the inclusion criteria, 19 had complete data. There were significant differences in oxygen saturation, respiratory rate, tidal volume/kg body weight, respiratory compliance and peak tidal expiratory flow /tidal volume, with or without vest compression.'] Do effects of compressive vests on pulmonary function of infants with thoracic burn scars?
