Incentive spirometer alinear VS linear as a resource to obtain respiratory muscle strength in the postoperative upper abdominal surgery

Abstract

The upper abdominal surgery favor a decrease in pulmonary volumes and capacities, as well as compromising the entire pulmonary function, thus impairing the progress of patients. This study aimed to assess respiratory muscle strength in the comparison between the techniques of incentive spirometry with alinear load versus linear in postoperative upper abdominal surgery, as well as verify that the incentive spirometer load alinear functions as a resource for obtaining respiratory muscle strength. Participants 14 patients, 01 men and 13 women, aged between 18 and 70 years undergoing abdominal surgery at Hospital CONSAÚDE. The volunteers were randomly allocated into two groups, and in group A was performed physiotherapy with incentive spirometer alinear (Respiron®) and in group B, with an incentive spirometer Linear Threshold® PEP, but in both groups were associated techniques such as diaphragmatic retraining, guidance for cough and when necessary, huffing associated with the use of the pillow. The results showed that both techniques favor an increase in MIP, where members of the group A, on average, performed better than Group B, however, considering the standard deviation we can conclude that the group B achieved better results.
