Right-to-left shunt and inhalation induction
Webperfusion study may also be used to quantify the right-to-left shunt fraction [12]. Lung scintigraphy allows correct interpretation of radiological hyperlucent areas, as in partial obstruction due to missed foreign body inhalation; it is also highly sensitive in detecting the late sequelae of it [13]. The A right-to-left shunt occurs when: 1. there is an opening or passage between the atria, ventricles, and/or great vessels; and, 2. right heart pressure is higher than left heart pressure and/or the shunt has a one-way valvular opening. Small physiological, or "normal", shunts are seen due to the return of bronchial artery blood and c…

Webon speed of induction; right-to-left (R-L) shunting significantly slows induction of N2O and halothane anesthesia; and adding an L-R shunt to a preexisting R-L shunt will attenuate the slowing of induction caused by the R-L shunt. Address correspondence to Dr. Tanner, Department of Anesthesiology, Veterans Administration Medical Center, West Spring … WebCardiac shunts may be: Left-to-right (acyanotic): This type of shunt doesn't affect the process of oxygenation in your lungs. Right-to-left (cyanotic): This type of shunt interrupts blood flow and oxygenation in your lungs. In these situations, you may have lower oxygen saturation in your blood or a bluish tinge to your skin.
