Purpose: to investigate pulmonary function in different phases of cardiac valve replacement surgery.Methods: This was a longitudinal study of a quantitative nature. The volunteers were male volunteers aged between 25 and 50 years, with valvar heart disease. Where the peak of expiratory flow (PEF) was evaluated in the preoperative period, in the postoperative period in the intensive care unit (ICU) and in the postoperative period in the ward. Up to eight measurements were performed, and the highest value of three reproducible and acceptable measurements was selected with a maximum variation of 10% of the value obtained. Statistical analysis was performed in the Bioestat 5.0 program, the Shpiro-Wilk test was used to verify normality and the Anova test to analyze the data variance, a significance level of p <0.05 was accepted.Results: peak expiratory flow was higher in the preoperative phase (500.00 ± 82.15) when compared to the evaluation period in the intensive care unit (421.11 ± 46.21) and after discharge from the therapy unit (452.22 ± 46.03).Conclusion: It was possible to observe changes in pulmonary function due to cardiac valve replacement surgery, and even after some time after surgery, pulmonary function did not return to the values prior to surgery.
