Does High-Frequency Chest Wall Oscillation Have an Impact on Improving Pulmonary Function in Patients With Smoke Inhalation Injury?

Smoke inhalation results in bronchospasm of the trachea, increasing secretion of mucus, casts formation, and improvement of blood flow of the airway. High frequency chest wall oscillation is a common modality used for clearing mucus secretion in patients suffering from hypersecretion of thick mucus and used also to help cough clearance. This study aimed to detect the effect of high frequency chest wall oscillation in improving pulmonary function in burn patients suffering from smoke inhalation. Sixty smoke inhalation injury patients were randomly distributed into two groups of equal size. Group A: received high frequency chest wall oscillation and conventional chest physical therapy (breathing exercises, early ambulation, and cough training) thrice per week for 8 weeks. Group B: received traditional chest physical therapy (breathing exercises, early ambulation, and cough training) thrice per week for 8 weeks. Pulmonary function test (forced vital capacity, forced expiratory volume in the first second and peak expiratory flow rate) was measured at enrollment and after 8 weeks by using spirometer. Pulmonary function increased significantly posttreatment when compared with that pretreatment in groups A and B (P > .001). Also, they increased significantly in group A compared with that of group B posttreatment (P > .05). High-frequency chest wall oscillation have an impact on improving pulmonary function and should be handled to be a part of the pulmonary rehabilitation plan for smoke inhalation injury patients. © The Author(s) 2020.
