Abstract

Patients with chronic respiratory conditions, such as COPD, neuromuscular diseases, kyphoscoliosis, and obstructive sleep apnoea-obesity hypoventilation syndrome (OSA-OHS), are more likely to experience decompensation in the form of hypercapnia respiratory failure, which can result in admission to the intensive care unit (ICU) and an increase in the patient's likelihood of passing away. Domiciliary noninvasive ventilation (NIV) in patients with diseases that cause chronic ventilatory failure is examined in this article, along with its mechanism of action.
