Abstract

A respiratory apparatus airflow tube configured to deliver an airflow from an airflow generator machine to a patient interface includes a flexible tube, a patient interface connector and a machine interface connector. The flexible tube includes a machine end, a patient end, and first and second heater wires extending from the machine end toward the patient end. The patient interface connector is attached to the patient end and is configured to attach to a patient interface. The machine connector is attached to the machine end and is configured to attach to an airflow generator machine. The machine connector includes an airflow housing having an interior wall defining an airflow pathway through which an airflow may be delivered into the machine end of the flexible tube and a temperature sensor located outside the airflow pathway.
