"WebCPAP will provide a constant pressure helping to stint open the alveoli. This will also recruit more alveoli that were previously closed, due to atelectasis, and open them to participate in Oxygenation. CPAP also increases intrathoracic pressure, which will decrease venous return to the heart and reduce preload. " - Bipap intrathoracic pressure
