Effect of Combination of Different Postures and Pursed Lips Breathing on Dyspnea and Pulmonary Parameters among Patients with Asthma

Abstract

Objective: To evaluate the effects of combining prostration position with pursed-lip breathing in adult asthma patients. Study Design: A quasi-experimental study Place and Duration of Study: This study was conducted at the at Emergency Department, Imam Hussein Medical City Karbala from 1st April 2025 to 30th September 2025. Methods: 60 patients of intervention n=30 and control n=30. The patient's contribution to the study was positive, as the nursing intervention was implemented by the patient himself. Results: The intervention group demonstrated significant improvements: respiratory rate decreased from (24.7) to (20.1) breaths/min (p=0.001), SpO2 increased from 91.7% to 93.5% (p<0.001), and dyspnea scores reduced from 15.4 to 14.1 (p=0.014). No significant changes occurred in controls. Participants were predominantly middle-aged (46.7-50% aged 30-49), obese (36.7% Class I), with chronic asthma (40% duration 11-20 years) using ICS+LABAs (40%). Conclusion: Prostrate position enhances diaphragmatic function and pursed-lip breathing reduces hyperinflation, supporting their integration into asthma care and education as a safe, effective intervention.
