摘要：
An anesthesia delivery and ventilation system (ADVS) includes an expiratory section, a circulation flow system (CFS), an inspiratory section, a ventilation drive system (VDS), and an anesthesia delivery system (ADS). The expiratory section receives gases from a patient and the inspiratory section and fresh gases from a fresh gas supply system. An elastic mixing reservoir receives and mixes the gases circulated by the CFS with residual gases via a connector element. The inspiratory section connects to the expiratory section at one end and to a patient connector tube at the other end. The ADS infuses an anesthetic agent into the mixed gases in the inspiratory section. The VDS delivers the mixed gases with the anesthetic agent to the patient. The VDS and the CFS are controlled and operate independently of each other to provide positive end-expiratory pressure control and ventilation control to the patient without use of a proportional valve.
