Abstract

Background: The respiratory symptoms of COVID-19 often persist in most patients with moderate to severe infection after recovery. Respiratory exercises help post COVID-19 in pulmonary recovery/rehabilitation. Aim:  investigate the effect of incentive spirometer on post-COVID-19 patient’s respiratory outcomes. Hypothesis: patients who had successfully used the incentive spirometer will have better respiratory outcomes 6 weeks after the isolation period. Design:Quasi experimental research design (pre and post-test- time serial). Subjects: 30 adult male and female patients with COVID-19 in a convalescent stage. Sample: Apurposive sample. Setting: one of the COVID 19 follow-up outpatient clinics. Results: the mean age of the studied sample was 47 ±2.984. Half of the studied sample had no chronic diseases and 16.7%had a history of hypertension. The majority of the studied sample 90.7% had dyspnea in the first assessment as compared to 40% in the fourth assessment. The current study represents a highly significant statistical difference between the four assessments regarding the numerical Dyspnea Scale and Modified Medical Research Council (mMRC) Dyspnea Scaleandthe use of incentive spirometer (χ2 = 74.98, df=21, P <0.001), (χ2=23, df=3, p=0.001), (χ2 =36.08, df=4,P<0.001)respectively, as well as a highly negative significant statistical correlation between incentive spirometer capacity and the Numerical Dyspnea Scale (rs = -0.867, P<0.001)and a moderate significant statistical negative correlation between incentive spirometer capacity and Modified Medical Research Council (mMRC)rs= -0.672/P=<0.001).and a moderate significant statistical negative correlation between incentive spirometer capacity and age (r= -0.491/P=<0.001). Conclusion:Respiratory exercises using an incentive spirometer have a positive effect on improving respiratory outcomes and decreasing the severity of dyspnea of post COVID 19 patients who had persistent pulmonary symptoms during the recovery phase. Recommendations:Further studies are necessary to establish whetherincentive spirometer is effective for the respiratory rehabilitation of COVID 19 patients.
