Abstract
System and method for prevention of surgical fires inside a patient's airway. The system includes a specially adapted endotracheal tube which carries sublines (in addition to the main line carrying anesthetic gases) for carrying an air sample back from the distal end of the tube to a remote oxygen sensor. Upon the sensor sensing an undesirably or dangerously high level of oxygen within the patient's airway, the system operates alarms to alert the surgical personnel, and also operates a controllable valve to admit an inert gas into other sublines associated with the endotracheal tube and which deliver the inert fire suppressing gas to the distal end of the tube, proximal to the cuff, inside the patient's airway.
