Definition Rate of uptake is dependent on 1) alveolar ventilation rate 2) partial pressure of gas (concentration effect) 3) breathing system For poorly soluble anesthetic agents (ex. N2O, desflurane), an increase in FA/Fi depends very little on alveolar ventilation. For soluble anesthetic agents (ex. isoflurane), an increase in FA/Fi depends significantly on alveolar ventilation.
