Abstract
Induction speed: alveolar pressure (PA)-arterial pressure (Pa)-Pbrain, thus PA is only an approximation of Pbrain. Blood passes though the capillaries of the lungs and the anesthetic partial pressure equalizes between the alveolar and arterial pressure. Then, due to the movement of arterial blood throughout the body, and after a short period of equilibration, the alveolar partial pressure of the gas equals the brain partial pressure. Alveolar partial pressure can be increased by increasing minute ventilation, increasing flow rates at the level of the vaporizer, and by using a nonrebreathing circuit.
