from hjrbiturate administration ts characterised by decreased tidal volume and increased ventilatory rate. Potent inhaled anesthetics displace the carbon dioxide response curve lo the right and decrease ihe slope, ihe degree of whxh depends on the anesthetic dose and thr Iciel of surgical stimulation, l-ike barbiturate*, the vennlatoey panern following adminntra- tKin of potent inhaled anesthetics is initially represented hv a decreased tidal volume and increased icntilatoey rate. As more potent anesthetic agent is administered, however, ventilatory rate decreases toward an apncK end point. This clinical response ocsurs when the carbon dmside response curse eventually becomes horiiontal iskipe = 0), resultinit in essentially no ventilatory response to Pa CO.
