WebJun 16, 2015 · So, with the normal" atmospheric pressure of 760 mm Hg, one's entire native respiratory circuit is under 10 metres of water pressure. Similarly, 10 metres below the surface of the sea one's lung experiences an extra 1 atmosphere of pressure, and with deeper submersion, the pressure increases by 1 atmosphere for every 10 metres. 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. WebCPAP will provide a constant pressure helping to stint open the alveoli.
