Abstract
An anesthetic system and a transportation ventilation system include a breathing circuit which is isolatable from ventilator machines and anesthesia machines. The breathing circuit is connectable to the patient and includes a respiration bag within an actuator bag which is translucent and inelastic. The ventilation machine supplies signals so that the respiration bag collapses and expands within the actuator bag through a multi-port valve structure.
