Abstract: An anesthesia machine that integrates the presence and charge status of another medical device, such as a video laryngoscope, into the operation. The anesthesia machine communicates with the medical device to determine the presence and charge status and present this information to the user as part of the checkout procedure. A medical device holder is associated with the anesthesia machine to receive and charge the medical device. The medical device holder can include both a medical device charging holder and a battery charging holder that receives and charges a replacement battery. The medical device holder can communicate with the anesthesia machine to provide the charge and presence status of the medical device. During the checkout procedure for the anesthesia machine, the user can be presented with the presence and battery status information or could be prompted to manually enter this information into the anesthesia machine.

Abstract: A method for an anesthesia system includes flowing ventilator drive gas through a bellowless plenum separating a ventilator drive gas circuit from an inspiratory gas circuit; and providing the ventilator drive gas flowing through the bellowless plenum to an inspiratory port of the inspiratory gas circuit.

Abstract: A patient transfer device is configured for use with at least one host device which is capable of providing respiratory support to a patient. The patient transfer device includes an inspiratory port and an expiratory port which are configured to pneumatically connect to the host. An inspiratory connection is pneumatically connected to the inspiratory port and an expiratory connection is pneumatically connected to the expiratory port. An inspiratory valve is coupled between the inspiratory port and the inspiratory connection and expiratory valve is coupled between the expiratory port and the expiratory connection. The inspiratory valve and the expiratory valve are operable between first configurations that permit flow there though and second configurations that occlude flow through the valves. The inspiratory valve and the expiratory valve are configured to operate in the second configuration when the patient transfer device is disconnected from the at least one host device.
