A method for one-lung ventilation of a lung comprising:
- inserting a single lumen endobronchial tube into in a trachea of a patient and a left main stem bronchi of a left lung of the patient, the single lumen endobronchial tube comprising:
- a medical tube comprising an endotracheal portion and a bronchial portion having a common single lumen extending between a proximal end and a distal end of the medical tube, wherein the proximal end of the endotracheal portion includes a first opening adapted for connection to an external mechanical ventilation device and the distal end of the bronchial portion includes a second opening adapted for delivery of a medical gas;
- a first endotracheal inflatable cuff positioned around an external surface of the endotracheal portion and adapted to expand radially outward for sealing against a trachea of a patient;
- a second endotracheal inflatable cuff positioned around an external surface of the endotracheal portion and located at a position distal to the first endotracheal inflatable cuff, the second endotracheal inflatable cuff adapted to expand radially outward for sealing against the trachea of the patient, wherein the first endotracheal inflatable cuff and the second endotracheal inflatable cuff are tapered in a same direction so that a proximal portion of the first endotracheal inflatable cuff and the second endotracheal inflatable cuff has a larger diameter than a distal portion of the first endotracheal inflatable cuff and the second endotracheal inflatable cuff;
- a bronchial inflatable cuff positioned around an external surface of the bronchial portion distal to the first endotracheal inflatable cuff and the second endotracheal inflatable cuff, the bronchial inflatable cuff adapted to expand radially outward against the left main stem bronchi of the patient;
- an aperture positioned between the first endotracheal inflatable cuff and the second endotracheal inflatable cuff and adapted to deliver an amount of medical gas to a second lung of the patient, wherein the aperture is beveled such that an interior aspect of the medical tube wall is at a 35-degree to 55-degree angle to an exterior aspect of the medical tube wall, and wherein the bevel is formed in a semi-lunar shape along a portion of the circumference of the aperture;
- an intraluminal balloon blocker positioned along an inner surface of the bronchial portion distal to the aperture and adapted to expand from a deflated state to an inflated state, wherein, when in an inflated state, the intraluminal balloon blocker forms an air-tight seal with the inner surface of the bronchial portion and has a rigidity sufficient to form an impassible member for instrumentation passing through the distal end of the medical tube, thereby directing the instrumentation out of the aperture and into the patient's lung;
- and
- wherein the common single lumen defines a single passageway that fluidly connects the aperture, the first opening, and the second opening with one another to selectively ventilate the left lung, a right lung, or both lungs of the patient;
- positioning the medical tube in a pulmonary airway of a patient such that a di bronchial inflatable cuff is in a left main stem bronchus, and the first endotracheal inflatable cuff and the second endotracheal inflatable cuff are in the trachea;
- connecting the proximal end of the medical tube to the external mechanical ventilation device;
- inflating the bronchial inflatable cuff radially outwardly to seal against a surrounding bronchus of the left lung;
- inflating at least one of the first endotracheal inflatable cuff and the second endotracheal inflatable cuff radially outwardly to seal against a surrounding trachea of the patient;
- and
- guiding an instrumentation through the common single lumen.
