Right-to-left shunt and inhalation induction
WebAnatomic right-to-left shunt (Fig. 19-2) occurs when venous blood enters the aorta through anatomic structures that bypass the pulmonary circulation. This includes desaturated blood from the bronchial and thebesian veins as well as abnormal extrapulmonary shunts (intracardiac shunts and shunts via the ductus arteriosus) and intrapulmonary shunts. WebHydrogen bromine redox flow batteries (RFB) are considered to be one of the most promising storage alternatives, as this technology offers both high energy and high-power density. In this work a printed circuit board type of segmented current collector for the measurement of locally resolved current density was developed. This analytical tool was …
