WebSep 19, 2013 · Concerns about denitrogenation atelectasis are more than balanced by the increased safety provided by improving the time to desaturation. Application of continuous positive airway pressure (CPAP) during preoxygenation can overcome these effects and minimize atelectasis. Positive pressure WebJul 14, 2024 · Preoxygenation is the removal of nitrogen from the body by oxygen. “Is preoxygenation the same as denitrogenation ?” The answer is not exactly. With …
