WebIn order to hasten denitrogenation, it is advisable to washout (flush) the anesthesia circuit by a high O 2 flow before applying the face mask to the patient. On preoxygenation of the patient, an O 2 flow per minute that eliminates rebreathing should be used. Therefore, three steps are required to enhance preoxygenation: WebAbstract Oxygenation, or rather denitrogenation, prior to apnea during anesthetic induction attempts to replace alveolar nitrogen with oxygen to achieve an intrapulmonary oxygen …
WebDuring emergence from anesthesia, residual effects of anesthetics and inadequate reversal of neuromuscular blockade can lead to hypoventilation, hypoxemia, and loss of airway patency.

This suggests that gas absorption plays an important role in the genesis of the atelectasis. A mathematical model was developed that combined models of gas exchange from an ideal lung compartment, …
WebAug 31, 2024 · The institution of hyperoxia (PaO 2 ≫13 kPa) gradually leads to nitrogen displacement (denitrogenation). The arteriovenous oxygen difference (i.e. PaO 2 – PvO 2) reflects the gradient favouring nitrogen absorption. A nitrogen bubble, 4 mm in diameter (i.e. 0.025 ml), takes more than 10 hours to be absorbed while breathing air, but less than ...
