Abstract: Cannula holders for holding a nasal cannula are described. The cannula holders may also be configured to hold a CPAP mask, BIPAP mask, nebulizer mask, or any other piece of medical equipment. The cannula holders may be used to help prevent a nasal cannula from coming into contact with unclean surfaces when not in use, helping to keep the nasal cannula clean. The cannula holders may help prevent a nasal cannula from falling onto the floor or elsewhere when not in use. The cannula holders provide an alternative to placing or hanging a nasal cannula on equipment, furniture, or elsewhere.
