Structural Differences in Respiratory System and Airway of Parturients Ayten Saracoglu<p>Oxygen consumption increases with increased alveolar ventilation and respiratory alkalosis occurs. Thus, PaCO2 becomes 28-32 mmHg in pregnant women, and this amount is compensated with renal bicarbonate absorption. Preoxygenation can be made slower by inhalation of 100% oxygen for 2-5 minutes.&nbsp; Denitrogenation of the lungs occurs after three minutes [1]. Another method can be applied quickly with 4-8 deep breaths of 100% oxygen [2]. However, for pregnant women who will have a cesarean section under&nbsp; general&nbsp;anesthesia, an oxygen fraction of 1 has been shown to increase fetal oxygenation more compared with the 0.3 or 0.5 FiO2 [3]. As this may lead to free oxygen radicals and apsorbtion atalectesia, 80 %&nbsp; oxygen is recommended.</p> Global Journal of Anesthesiology - Peertechz Publications 2015-10-15 Editorial https://doi.org/10.17352/2455-3476.000016 en Copyright © Ayten Saracoglu et al.
