Airway Clearance Using Non-Invasive Oscillating Device

NIOD will be implemented on four different parts of the chest walls, 3 minutes for each part and 12 minutes in total per each session. Left and right front and posterior chest walls will be stimulated (Figure1), particularly, on the anterior chest, intercostal spaces 1-2 above nipple line and lateral side of the midclavicular line 1-2 below intercostal spaces. The intensity of the NIOD can be selected between 80-100%, which is prespecified on the machine.
