<![CDATA[Pulmonary tuberculosis complicated by human immunodeficiency virus infection may contribute to respiratory impairment, increased work of breathing, secretion retention, and dyspnea. Active Cycle of Breathing Technique (ACBT) is a non-pharmacological respiratory intervention designed to improve breathing control, lung expansion, and airway clearance. This case report evaluated short-term respiratory responses to ACBT in a patient with suspected pulmonary tuberculosis, HIV, dyspnea, and an ineffective breathing pattern. The patient presented with shortness of breath, rapid, shallow breathing, use of accessory muscles, a respiratory rate of 28 breaths/min, and peripheral oxygen saturation of 97% while receiving oxygen via a non-rebreather mask at 10 L/min. ACBT was implemented as part of nursing care, in combination with semi-Fowler's position and standard respiratory management. The intervention was performed for approximately 10–15 minutes over three consecutive days, with respiratory rate and oxygen saturation assessed before and after each session. Respiratory rate generally decreased following ACBT, with the greatest reductions observed on the third day, from 28 to 25 breaths/min and from 26 to 24 breaths/min. Oxygen saturation remained stable or increased, reaching 99% after selected sessions. The patient also demonstrated improved breathing control and reduced respiratory effort. Repeated ACBT sessions were associated with short-term improvements in respiratory rate and with maintenance or modest improvements in oxygen saturation. ACBT may represent a feasible adjunctive nursing intervention for respiratory symptom management, although larger controlled studies are required to confirm its independent and sustained effects.]]>
