2. Fig 1
Examples of data fits of the effect of remifentanil on breathing obtained in three volunteers. Each blue open circle is one breath; the green line is the predicted ventilation; and the pink filled trangle is the remifentanil bolus administration (50 µg). (a and b) Data sets obtained during air breathing. (c) Data set obtained during breathing of high inspired oxygen.

Simulation of the effect of administration of multiple remifentanil boluses (30 µg) on ventilation during conditions of no pain (green) and during conditions of constant mild to moderate pain (blue), causing an increase in baseline ventilation of ∼50%.
