title: Gas and vapor delivery.
abstract: Technology for gas and vapor delivery has not changed substantively in decades. Technology possessing greater precision and reliability has been in use by nonmedical industries to regulate gas flows and to vaporize liquids. Adaptation of existing technology to the needs of anesthesia delivery systems requires stimulus from the anesthesia community and commitment from the anesthesia device industry. No insurmountable problems are evident, but the perennial problem of inertia has prevented progress consistent with that seen in other fields of biomedical technology.
