I, IIMechanical insufflation-exsufflation is a technique used to help clear secretions from the airways, particularly in patients who have difficulty coughing due to neuromuscular disorders or other conditions. If the glottis collapses during exsufflation, the effectiveness of the technique is compromised because air cannot flow freely out of the lungs, preventing the removal of secretions. Similarly, the presence of a fixed airway obstruction would also hinder the effectiveness of this technique, as the obstruction would block the flow of air and secretions out of the airways. However, the presence of a chronic neuromuscular disorder is actually an indication for the use of mechanical insufflation-exsufflation, as these patients often have difficulty generating sufficient cough strength on their own.
