The aim of this study was to determine the effect of preoperative use of different respiratory exercise devices on postoperative outcomes in elderly lung lobectomy patients.

This study was retrospectively conducted between 03.12.2024 and 5.02.2025 in the Thoracic Surgery Clinic of a university with 82 patients using 41 Triflow and 41 Acapella. The information obtained from the online files of the patients was entered into the SPSS program using the Patient Introduction Form and Patient Follow-up Form. Descriptive analyses, independent sample t-tests, Mann-Whitney U tests, and chi-square tests were used to evaluate the data.

In the study, the postoperative hospitalisation time of the acapella group was higher than that of the triflow group, and this difference was statistically significant (p: 0.042). In addition, the saturation value on the 3rd postoperative day (p:0.023) was significantly higher in the triflow group than in the acapella group. On postoperative days 4 and 7, the pain score (p:0.012) was significantly lower in the Triflow group than in the Acapella group.

In the study, it was determined that the hospitalisation period was shorter, the saturation value was higher on the 3rd postoperative day, and the pain score was lower on the 4th and 7th postoperative days in the Triflow group compared to the Acapella group as a respiratory exercise device in elderly patients with lung lobectomy.
