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

Abstract

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 (O2) 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 O2, 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.
