Pulmonary tuberculosis (TB) is an infectious disease that can impair respiratory function and reduce oxygen saturation. Benson relaxation therapy represents a simple non-pharmacological approach that combines relaxation, controlled breathing, and focused concentration to support physiological comfort and oxygenation. This study aimed to describe the application of Benson relaxation therapy in improving oxygen saturation among pulmonary TB patients at Warungasem Public Health Center, Batang. A descriptive case study design was applied involving five pulmonary TB patients who met the predetermined inclusion criteria. Benson relaxation therapy was administered for 10–15 minutes per session over three consecutive days, while oxygen saturation was measured before and after the intervention using a pulse oximeter. Data were analyzed descriptively by comparing individual and mean oxygen saturation values before and after therapy. Before the intervention, all participants had mild hypoxemia, with oxygen saturation values ranging from 90% to 92% and a mean of 91.2%. After the intervention, oxygen saturation increased to a range of 94%–96%, with a mean of 95.2%, and four participants reached the normal category. All participants experienced an increase of four percentage points. These findings indicate a consistent descriptive improvement following Benson relaxation therapy and support its potential use as a simple complementary nursing intervention for pulmonary TB patients.
