Alveolar tension of a hypothetical anesthetic gas of low solubility after 10 breathing cycles. Alveolar tension approaches inspired tension.

doses of anesthetic must be administered to avoid excessive CNS depression. The use of significantly lower doses of IV anesthetic drug also should be a consideration in elderly patients, since they have low cardiac output, low lean body mass, and frequently a reduced capacity for drug clearance.

The effect of increased cardiac output on the administered dose of anesthetic is opposite that discussed for reduced cardiac output. Intensely anxious patients and those who have such diseases as thyrotoxicosis usually require larger doses of anesthetic to induce anesthesia.
