WebSep 8, 2013 · But in reality, pulmonary circulation does take up anesthetic from the alveoli and therefore FA always lags behind FI i.e. FA / FI ratio is < 1.0 Greater the uptake, slower the rate of rise of alveolar concentration and lower the FA / FI ratio i.e. longer it takes for induction to achieve. 8. WebThis condition is the narrowing of the aorta close to the ductus arteriosus insertion site. This leads to creater upper extremity perfusion and a decreased lower extremity perfusion.
