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

Overview

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.

Pleural effusion is the pathological accumulation of excess fluid in the pleural cavity, compromising lung function by limiting expansion and reducing compliance. This condition leads to symptoms such as dyspnea and impaired gas exchange, which can significantly affect pediatric patients. Treatment often includes physical therapy techniques to facilitate lung expansion and improve respiratory function. The present study comprises Bubble Positive Expiratory Pressure, which involves exhalation through water to create resistance and improve expiratory volume, and Segmental Breathing, which enhances inspiratory volume for lung expansion. In contrast, Incentive Spirometry provides visual feedback to guide deep inhalation; it includes both upside and upside-down usage of the spirometer for the maintenance of pulmonary function and preventing alveolar collapse.
