Noninvasive ventilation has been shown to:
- Improve gas exchange with increased PO2 and decreased PCO2.
- Improve hemodynamics with decreased pulmonary artery pressure and increased right ventricular function.
- Reduce work of breathing.
- Normalise sleep patterns with fewer apnoeic episodes.
- Reduce hospitalisations and improved quality of life.
- Provide relief from dyspnea.
