  • Patent number: 10010689
    Abstract: Described herein is a nasal cannula apparatus. The apparatus is configured to detect the pressurized flow of breathable gas to and/or from the airway of a subject through the nose of the subject. The apparatus comprises a body, a first nasal cannula system formed in the body configured to engage a first nostril of a first nasal passage, and a second nasal cannula system formed in the body configured to engage a second nostril of a second nasal passage of the subject. The second nasal cannula system is joined to first nasal cannula system by a bridge such that the first nasal cannula system engages the first nostril and second nasal cannula system engages the second nostril at the same time. The apparatus is configured to transmit expiratory and inspiratory nasal pressurized flow to connective conduits.
