An interventional study of Pursed-Lip Breathing (PLB) in Pneumonia, sponsored by Ataturk University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 3 Years to 4 Years. Per ClinicalTrials.gov, last updated 2026-09-28.
Sponsored by Ataturk University · Not applicable, Interventional, and Treatment
This study aims to evaluate the effects of Pursed-Lip Breathing (PLB) exercises on physiological parameters (such as respiratory rate, heart rate, and oxygen saturation) and discharge readiness in children diagnosed with pneumonia. The study is designed as a randomized controlled trial involving pediatric patients between the ages of 3 and 4. The intervention includes guided PLB exercises performed twice daily for three consecutive days. Data will be collected before and after each session to assess changes in physiological measures and readiness for hospital discharge.
Pneumonia remains one of the leading causes of hospitalization and morbidity in early childhood, often requiring supportive respiratory interventions. Pursed-Lip Breathing (PLB) is a simple, non-pharmacological respiratory technique that has shown promise in improving respiratory function by increasing exhalation time, enhancing oxygenation, and reducing respiratory workload.
This randomized controlled trial aims to evaluate the effects of PLB exercises on physiological parameters (respiratory rate, heart rate, and oxygen saturation) and readiness for hospital discharge in children aged 3-4 years diagnosed with community-acquired pneumonia. Participants will be randomized into intervention and control groups. The intervention group will receive PLB exercises using a toy-based blowing device (saxophone ball blower) twice daily for three consecutive days under supervision, while the control group will receive standard care.
Physiological parameters will be measured immediately before and after each PLB session using standardized methods. In addition, parental perception of discharge readiness will be assessed using the Pediatric Readiness for Hospital Discharge Scale - Parent Form (Ped-RHDS) on the first and third days of hospitalization.
The study hypothesizes that PLB exercises will lead to improved oxygen saturation, reduced respiratory and heart rates, and increased readiness for discharge in the intervention group compared to controls. This research will contribute to the evidence supporting non-pharmacological nursing interventions that can enhance respiratory outcomes and discharge processes in pediatric pneumonia patients.

Exclusion Criteria:
Children aged 3-4 years diagnosed with pneumonia will receive only standard hospital care. No additional respiratory exercise will be applied. Physiological parameters will be measured at the same intervals as the intervention group for comparison.
Children aged 3-4 years diagnosed with pneumonia will receive Pursed-Lip Breathing (PLB) exercises under nurse supervision, twice daily for three consecutive days. PLB will be performed using playful methods with a toy (e.g., saxophone ball). Respiratory rate, heart rate, and oxygen saturation will be measured before and after each session.
Behavioral: Pursed-Lip Breathing (PLB)
Children in the intervention group will receive Pursed-Lip Breathing exercises twice daily for three days under nurse supervision. Exercises will be applied using playful techniques with a toy (e.g., saxophone ball). Physiological parameters will be measured before and after each session.
Change in Respiratory Rate
Respiratory rate will be measured before and after each PLB session to evaluate the intervention's effect on pulmonary function.
Time frame: Before and after each PLB session over a 3-day intervention period
Change in Heart Rate
Heart rate will be recorded before and after each PLB session to assess changes in cardiovascular response.
Time frame: Before and after each PLB session over a 3-day intervention period
Change in Oxygen Saturation (SpO₂)
Peripheral oxygen saturation (SpO₂) will be evaluated before and after each PLB session to determine its impact on oxygenation.
Time frame: Before and after each PLB session over a 3-day intervention period
Change in Pediatric Readiness for Hospital Discharge Scale - Parent Form (Ped-RHDS) Scores
The Pediatric Readiness for Hospital Discharge Scale - Parent Form (Ped-RHDS) will be administered to parents by an independent nurse on Day 1 (morning) and Day 3 (evening) of hospitalization. The scale evaluates parents' perceptions of their child's readiness for discharge. The total score ranges from 0 to 100, with higher scores indicating a greater perceived readiness for hospital discharge. This outcome measure will be used to assess the effect of the PLB intervention on discharge preparedness.
Time frame: Day 1 (morning) and Day 3 (evening)
