Effect of Cough Assist Device on Hemodynamic Status and Oxygen Saturation for Ventilated Children

ABSTRCT Background:Coughing is an important protective mechanism for cleaning airways from fluids and foreign substances.Life-threatening situations may emerge when coughing loses its efficiency due to muscular weakness or impaired mucociliary function.Objective: This study aimed to investigate how a cough assist device affects hemodynamic monitoring and oxygen (O 2 ) saturation in children using mechanical ventilation (MV).Patients and methods: Fifty children who had pneumonia and receiving MV, from both gender with age ranged from 4 to 9 years old, were included in this research study.The children were divided into two equal groups using a random way: The intervention group received both a cough assist device and conventional chest physiotherapy, while the control group received only conventional chest physiotherapy.Results: Compared to the control group, the intervention group had a substantial reduction (p < 0.05) in respiratory rate (RR) and a significant rise (p < 0.01) in O 2 , VTe, and Cdyn following treatment.Conclusion: Children on MV had improved respiratory parameters, oxygen saturation, and chest condition when a cough assist device was used combined with conventional chest physical therapy.
