Abstract
Improved system for delivering a controllable concentration of anesthetic gas to a patient by eluting with a carrier gas a solid polymeric adsorbent previously loaded with an anesthetic, the concentration being dependent only on the adsorbent temperature and the initial quantity of adsorbed anesthetic. Preferred embodiments utilize the polymeric adsorbent's capability of delivering a broad range of concentrations at low flow rates in a recycle delivery system.
