ABSTRACT
Noninvasive positive pressure ventilation (NIPPV) has been used in outpatients with sleep apnea, sleep disorders associated with heart failure, restrictive pulmonary diseases (subsuming neuromuscular diseases and thoracic cage deformities), severe stable chronic obstructive pulmonary disease, and the obesity-hypoventilation syndrome. NIPPV in these settings has resulted in significant physiologic benefits, improved quality of life, and in some cases longer survival. We discuss the modes of NIPPV, current indications, and potential benefits.
