ABSTRACT
Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with
no known cure. Involvement of muscles of the respiratory system, the inspiratory,
expiratory, and upper airway muscles, is the major cause of morbidity and mortality.
Dyspnea, swallowing difficulties, sialorrhea, and impaired cough are all symptoms
that can be palliated with pharmacological and nonpharmacological methods. Noninvasive
positive pressure ventilation (NPPV) in particular is a technique to assist ventilation
that not only relieves dyspnea and ameliorates respiratory failure but may also extend
the lives of patients with this disease. It should be offered to all ALS patients
with a forced vital capacity of less than 50%.
