| Abstract |
People with pulmonary tuberculosis often experience ventilation disorders
due to lung tissue damage, leading to decreased elasticity and increased
airway resistance. This condition reduces tidal volume and disrupts gas
exchange and oxygenation. One nonpharmacological intervention that can
help improve tidal volume is deep breathing exercise, which enhances lung
ventilation and oxygenation. This study aimed to analyze the effect of deep
breathing exercise on tidal volume in pulmonary tuberculosis patients at the
Main Clinic of Purwokerto Community Lung Health Class A. A quasi-
experimental design with one group pre-test and post-test was used,
involving 28 patients in the intensive phase selected through total sampling.
The intervention was conducted for three days. Tidal volume was measured
via interactive video calls at the patients' homes using balloons and
calculated with the formula V = πr2t. Each session was measured three
times, and the highest value was recorded. The mean tidal volume increased
from 2834.32 ml before intervention to 5365.00 ml after. Wilcoxon test
results showed a p-value of 0.001, indicating a significant difference. In
conclusion, deep breathing exercise is effective in increasing tidal volume in
pulmonary tuberculosis patients and can be considered a supportive
therapy. |
