Comparison of Mechanical Insufflation-Exsufflation and Endotracheal Suctioning in Mechanically Ventilated Patients: Effects on Respiratory Mechanics, Hemodynamics, and Volume of Secretions.

Context: Cough assist (CA) is a device to improve bronchial hygiene of patients with secretion in the airways and ineffective cough.

Aims: To compare the physiological effects and the volume of secretion of mechanical insufflation-exsufflation (CA device) with isolated endotracheal suctioning in mechanically ventilated patients.

Settings And Design: Randomized crossover trial.
