Effect of incentive spirometry on pulmonary function test in post COVID-19 pneumonia patients

Background. COVID-19 caused by SARS-CoV-2 virus was assigned as a pandemic WHO. Fever, breathlessness, cough and expectoration indicates lung involvement in the form of pneumonia its most common complications are pulmonary fibrosis, chronic respiratory failure reduced quality life. Incentive spirometry is relevant therapy to enhance normal function improve Aim. To find effect incentive on test post patients. Methodology. An experimental study with simple random sampling (lottery method) 24 patients age group (18-68 years). The participants were randomly divided into 2 groups. Group A received pharmacotherapy B only pharmacotherapy. Computerized Diffusion capacity for carbon monoxide (DLCO) used diagnostic tool measure pre & values both Intervention given 4 weeks after weeks, analyze post-test taken Outcome measures. Forced expiratory volume first second (FEV1), vital (FVC), FEV1/FVC &DLCO. Results. Statistical analysis shows significant improvement (p < 0.05) between pretest Pulmonary Function Tests (PFT) A&B whereas there increase intervention than control group. Conclusion. improved capacities PFT also these have mainly restrictive pattern use DLCO.
