Introduction The incentive spirometer helps pulmonary ventilation and the cardiorespiratory changes of its use are controversial. Objective To evaluate the effect of sets and repetitions on cardiorespiratory parameters using a spirometer alinear flow (SAF). The sample group consisted of 50 young people, healthy and sedentary. The evaluated parameters were: systolic blood pressure (SBP), diastolic (DBP), heart rate (HR), respiratory rate (RR), oxygen saturation (SaO2), minute volume (VE), tidal volume (VT), vital capacity (VC), maximal inspiratory pressure (Pimax), maximal expiratory pressure (Pemax), and peak expiratory flow (PEF). The moments of study were: initial evaluations (M1); 3 sets of 10 repetitions using SAF (M2); 3 sets of 15 repetitions using SAF (M3); and final evaluation (M4). Statistical analysis was made by t test, ANOVA and Tukey test (p < 0.05). Results SBP and HR decreased in M2 after the 2nd set. In the 3rd set, SBP and RR decreased. Comparing the initial and final variables in M2, SBP and RR decreased, and Pemax increased. After 1st set in M3, SBP and SaO2 decreased. The 2nd set: SBP, HR, RR, and SaO2 decreased. After the 3rd set: SBP, HR, SaO2, and RR decreased. Comparing the initial and final variables in M3, SBP, HR, RR decreased, and Pimax and Pemax increased. Comparing M4 to M1, Pimax, Pemax, and VC increased, and RR decreased. Conclusion There are changes in cardiorespiratory parameters after the use of a spirometer alinear flow, especially in the sets with more repetitions.
