How does positive pressure ventilation help in heart failure?
Answer
The positive airway pressure splints the airways open, driving transudated fluid out of the alveoli
-this decreases preload to LV, reducing the work of breathing
-decreases LV preload by minimizing venous return to the LA & LV
-may increase afterload of RV
