About

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.

Full description

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.

---

40 participants in 2 patient groups

Group A: Intervention Group (Bubble PEP + Segmental Breathing)

Active Comparator group

Description:

The experimental group will receive Bubble PEP therapy and Segmental Breathing along with conventional chest physiotherapy and mobility training. Bubble PEP will be performed using a bottle device where children exhale through a water-submerged tube, creating resistance to improve lung expansion and secretion clearance (10 repetitions, progressing from 1 to 3 sets over 14 days). Segmental Breathing will focus on localized lung expansion with therapist-guided tactile feedback, performed at six breaths per minute, progressing from 1 to 3 sets. Chest percussion will be applied for 2-5 minutes with rest intervals, and walking distance will increase from 1 to 5 meters. All sessions will be conducted once daily for two weeks.

Treatment:

Other: Bubble PEP

Group B: Control Group (Incentive Spirometry)

Active Comparator group

Description:

Participants in the control group will receive Incentive Spirometry along with conventional chest physiotherapy and mobility training. Incentive Spirometry will be used to encourage sustained maximal inspiration, thereby promoting lung expansion and improving ventilation. Each session will include three repetitions per side during Days 1-3, five repetitions per side during Days 4-7, and ten repetitions per side during Days 8-14, performed in one set per session. Chest percussion will be administered on the contralateral side to facilitate secretion mobilization, performed for two minutes on Days 1-3, three minutes on Days 4-7, and five minutes on Days 8-14, with 15 seconds of rest after each minute. Mobility training will include walking exercises, starting from one meter on Day 1, increasing to three meters by Day 3, and progressing to five meters from Day 4 onward, performed in two sets during Days 8-14. All sessions will be conducted once daily for two weeks.
