Spontaneous versus spontaneous timed mode of assisted ventilation in extrathoracic restrictive lung disease

Abstract

Restrictive lung disease can be divided into intrathoracic restriction due to parenchymal causes and extrathoracic restriction due to chest wall disease or neuromuscular disease. Patients with extrathoracic lung restriction suffer from shortness of breath, disturbed sleep and eventually type two respiratory failure when their condition progresses. Type two respiratory failure is characterised by hypoxaemia and hypercapnia. Effective treatment of this type of respiratory failure involves ventilatory support in the form of assisted mechanical ventilation. Non-invasive positive pressure ventilation has been a major advance in delivering mechanical ventilation since the late 1980’s. This can be..
