Abstract:
Pulmonary complications are the most common causes of mortality in patients with severe inspiratory and/or expiratory muscle weakness. An inspiratory tidal volume below 1500 ml and a peak cough flow below 160 L/min result in mucus retention and increase the risk of pneumonia. An intact cough function is pivotal for airway clearance during acute and chronic airway infections with increased mucus production as well as for protection against endotracheal aspirations. Effective cough requires that all of its phases work or are effectively supported. Non-invasive assistance of inspiration can be provided by manual hyperinflation, air stacking, glossopharyngeal breathing or mechanical insufflation. Safe and effective methods of expiration assistance include manual thorax and abdominal compression, manual self-assistance as well as mechanical insufflation-exsufflation. The use of these non-invasive inspiratory and expiratory muscle aids can decrease the risk of pulmonary complications in patients with severe ventilatory muscle weakness.

Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...

Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed.
