Prolonged respiratory disorders in post-COVID-19 patients still exist after patients return to the hospital. Deep breathing exercises are recommended that can increase the vital capacity of the lungs. This study aimed to identify the effect of a deep breathing exercise on vital lung capacity in post-COVID-19 patients. The intervention group (20) received deep breathing exercises, and the control group (20) received standard care. The vital lung capacity was evaluated after two weeks. The findings show that there is increased functional capacity for both groups. There is increasing the functional capacity increased in L from a mean of 1.73 with SD 0.38 to 1.87 with SD 0.37 (p=0.000, CI 95%) in the intervention group, and in the control group, it increases from 1.63 with SD 0.21 to 1.73 with SD 0.21 (p=0.008, CI 95%). The finding of the t-test result showed a significant difference in the average value of the vital lung capacity before and after the intervention between the intervention and the control groups (p=0.008; 95% CI=0.02-0.07). A deep breathing exercise improves the vital lung capacity of post-COVID-19 patients.
