Value of incentive spirometry in routine management of COPD patients and its effect on diaphragmatic function

Abstract Background Incentive spirometry (IS) is mostly used postoperatively to avoid pulmonary complications, but its effect on COPD patients and diaphragmatic functions are still not fully studied. The current study aimed evaluate the value of IS arterial blood gases, mMRC dyspnea scale, spirometry, by ultrasound in hospitalized for exacerbation. Methods Forty (37 males, 3 females) were admitted exacerbations divided randomly into 2 groups: Group1 (G1) =20 (mean age 60.7±5.99) incentive months with medical treatment. Group as a control group (G2) = 20 60.3±6.44) given treatment only. ABG, assessed admission after groups. Results There statistically significant differences between G1 G2 regarding PaCO , FEV1/FVC ( p =0.001 0.042, respectively), Lt excursion diaphragm thickness ratio. was increase results PaO FEV1/FVC, PEFR, all findings I before no difference FVC scale. Conclusion seems improve together improving functions. Trial registration ClinicalTrials.gov NCT05679609. Retrospectively egistered 10 January 2023
