Abstract

A medical device may include a gas delivery apparatus, a patient interface, a connection system, and an electrical circuit. The gas delivery apparatus may be configured to deliver gas to a patient. The patient interface may be configured to interface with the patient to deliver gas communicated by the gas delivery apparatus to the patient. The connection system may be configured to communicate gas from the gas delivery apparatus to the patient interface. The electrical circuit may be configured to communicate electrical signals between the patient interface and the gas delivery apparatus, and may including one or more first electrical conductors at least partially integral with the patient interface and one or more second electrical conductors at least partially integral with the connection system.
