Popis: ABSTRACT The main objective of this study is to associate the healthy area of the lung (evaluated by radiography) with the data of respiratory mechanics in children with atelectasis after cardiac surgery, under mechanical ventilation in the assisted controlled mode. Altogether, 46 children were selected, but 16 were excluded due to irregular respiratory waves or lack of the data on arterial blood gases. A group of 30 children under assisted controlled mode were analyzed, and 10 from this group developed atelectasis. The data were analyzed before and after the onset of atelectasis, and respiratory mechanics was correlated to radiography. We also analyzed the data related to arterial blood gas of these children - who initially had no pulmonary complication - to verify possible changes due to assisted controlled cycles. Atelectasis may modify some parameters of respiratory mechanics. In the association of the healthy area of the lung with the respiratory mechanics, the Spearman correlation results showed statistical significance of the lung area with airway resistance (ρ=−0.648 and p=0.043). Our results show that it is possible to analyze respiratory mechanics waves by selecting controlled cycles in the assisted controlled mode, since we found insignificant changes in potential ionic hydrogen. The analysis of respiratory mechanics allows checking lung function and undesired lung injuries; the analysis of respiratory mechanics can be daily performed in these children to have important information on the pulmonary function. Our research also showed that under the assisted controlled mode is also possible to evaluate respiratory mechanics.
