A breathing tube support device for holding and supporting one or more flexible breathing tube(s) of a breathing circuit during provision of anesthesia, assisted and artificial ventilation and/or spontaneous ventilation has a flexible support arm formed of a length of flexible axially extendable and collapsible corrugated tubing, a mounting base at a bottom end thereof for attachment to the patient or a support surface, and a breathing tube holder a top end thereof for receiving and supporting a section of the breathing tube(s). The flexible support arm can be expanded to increase its length longitudinally and collapsed upon itself to shorten its length longitudinally, and is sufficiently flexible to assume a bent or curved configuration, and sufficiently stable to retain the bent or curved configuration, whereby breathing tube(s) held and supported by the device can be optimally positioned relative to the patients head and neck area.
