Effect of Bubble Positive Expiratory Pressure and Segmental Breathing Versus Incentive Spirometry in Pleural Effusion

Conducted as a randomized clinical trial, this study will include 40 pediatric participants aged 5-16, recruited from Gulab Devi Chest Hospital and Children\'s Hospital, Lahore. Participants will be randomly divided into two groups: one receiving Bubble PEP with Segmental Breathing and the other using Incentive Spirometry, both combined with conventional chest physiotherapy and mobility. Outcome measures, including lung expansion (via X-ray), dyspnea (assessed using the Pediatric Dyspnea Scale), chest expansion (measured with a measuring tape), oxygen saturation (SpO₂), and respiratory rate, will be recorded pre- and post-intervention. The study hypothesises that the Bubble PEP and Segmental Breathing approach may offer a cost-effective and efficient alternative to Incentive Spirometry, particularly for patients who cannot afford mechanical devices. Statistical analysis will be performed using SPSS version 2023 to determine the intervention\'s effects.
