Abstract
Systems and methods for measurement of end tidal carbon dioxide, including a device having a body and a tubular gas line. The body is adapted to be attached to a patient airway and has a first gas line securing portion which has an aperture through it and is adapted to secure the gas line to the body. The tubular gas line is secured in the aperture. The tubular gas line has a proximal portion extending from a proximal end of the aperture and has a proximal end which is adapted to be connected to an end tidal CO2 monitor. The tubular gas line also has a distal portion extending from a distal end of the aperture and having a distal end which provides an inlet for end tidal CO2 exhaled by a patient.
Claims16
A system comprising:
- an oral airway having a tubular passageway adapted to be inserted into a patient's mouth in order to enable the patient to breathe through the passageway, the oral airway having a flange at a proximal opening of the tubular passageway;
- a body which is secured to the oral airway,
- wherein the body has a first gas line securing portion adapted to secure a gas line to the body, the first gas line securing portion having an aperture therethrough;
- and
- a tubular gas line secured in the aperture,
- the tubular gas line having a proximal portion extending from a proximal end of the aperture and having a proximal end adapted to be connected to an end tidal CO2 monitor,
- the tubular gas line having a distal portion extending from a distal end of the aperture and having a distal end which provides an inlet for end tidal CO2 exhaled by a patient;
- wherein the first gas line securing portion is positioned near a central opening through the body, thereby securing the tubular gas line in a position in which the distal portion of the tubular gas line extends into the central passageway of the oral airway
- wherein the oral airway comprises a bite block airway, the body having a separation wall connected thereto, wherein the separation wall extends into the central passageway of the bite block airway and partitions the central passageway, creating a first, larger portion and a second, smaller portion, wherein the distal portion of the tubular gas line is positioned in the second portion of the central passageway and wherein the distal end of the tubular gas line is physically separated by the separation wall from the first portion of the central passageway.
A method for providing a conduit in an oral airway to monitor end tidal CO2, the method comprising:
- providing an oral airway having a tubular passageway adapted to be inserted into a patient's mouth in order to enable the patient to breathe through the passageway, the oral airway having a flange at a proximal opening of the tubular passageway, wherein the oral airway comprises a bite block airway, and wherein the body has a separation wall connected thereto;
- providing an attachment body, the attachment body having a conduit therethrough;
- securing the attachment body to the oral airway so that a distal portion of the conduit is secured in a predetermined position with respect to the oral airway, wherein the distal portion of the conduit extends through an opening at a proximal end of the oral airway and into a central passageway of the oral airway, wherein securing the attachment body to the oral airway comprises positioning the body with the separation wall extending into the central passageway of the bite block airway and partitioning the central passageway into a first, larger portion and a second, smaller portion, and positioning the distal portion of the tubular gas line in the second portion of the central passageway with the distal end of the tubular gas line physically separated by the separation wall from the first portion of the central passageway;
- positioning the oral airway in a patient's mouth;
- and
- coupling a proximal end of the conduit to a CO2 monitor.
