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. WebApr 15, 2024 · Causes — Development of hypervolemia is generally due to excessive volume administration. In many cases, intraoperative fluid is administered to treat hemodynamic instability due to vasodilation, surgical bleeding, myocardial dysfunction, or vascular permeability. This often results in postoperative fluid overload.

WebSep 25, 2013 · The rate of induction is more rapid in infants and children than adults and corresponds to a more rapid increase in alveolar towards inspired anaesthetic partial pressure. This has been attributed to a larger ratio of alveolar ventilation to functional residual capacity, increased cardiac output, and greater delivery of cardiac output to … WebMar 28, 2024 · 2. Alveolar blood flow: if there is no pulmonary shunting, alveolar blood flow is equal to the cardiac output (CO). Increase in CO → more rapid uptake of agent → slower rise in F A /F i.; Low CO → less uptake → ↑ rise in F A /F i → quicker induction.; Change in …
