Hemodynamic Effects of CPAP
| Increase right atrial pressure |
| Reduce cardiac pre-load |
| Improve oxygenation |
| Suppressed catecholamines |
| Reduced ventricular wall tension or after-load |
| Improved mitral regurgitation |
| Reduce pleural pressure required for inspiration by improving lung compliance |
| Improved right-ventricular after-load through reduced pulmonary vasoconstriction from hypoxemia and catecholamines |
CPAP = continuous positive airway pressure
