Abstract
A method and apparatus for endotracheal intubation with simultaneous oxygenation/ventilation employs a curved guide and a light wand to ensure proper placement of the endotracheal tube in the patient's airway. The light wand has an elongated flexible member with a light source at its distal tip. The wand is inserted through an endotracheal tube until the light is adjacent to the distal end of the endotracheal tube. A curved guide is inserted into the patient's mouth and upper airway so that its distal end is positioned above the larynx. The wand and endotracheal tube are then advanced along the guide until the distal end of the endotracheal tube passes through the larynx and the light source is externally observable at a predetermined location through the anterior tracheal wall.
