BEN-GURION UNIVERISTY OF THE NEGEV FACULTY OF ENGINEERING SCIENCES DEPARTMENT OF ELECTRICAL AND COMPUTER ENGINEERING Detection of One Lung Intubation Incidents

During general anesthesia, voluntary breathing is stopped and the patient needs to be ventilated. The most common and the only method that suits long-term period of anesthesia is ventilation using an endotracheal tube, which is placed in the trachea. The location of the tip of tube is critical: it should be placed, and maintained above the bifurcation. A correct position of the tube, in which both lungs are ventilated, is called Tracheal Intubation (TRI). If the tube is misplaced or shifted due to patient movements, cases of One Lung Intubation (OLI) may occur. Prolonged cases of OLI should be avoided since it may cause insufficient oxygenation and may damage the non-ventilated lung. OLI was found to be the most probable cause of
