Abstract
Children and adults suffering from Upper Airway Obstructions (UAOs) are nowadays examined using an invasive endoscopy. Because this diagnostic technique unavoidably exposes the patient to certain health risks, there exists a clear need for a non-intrusive diagnostic tool. Several research programs have been initiated that aim at the development of such a tool. One of these initiatives attempts to determine the nature of the obstruction based on an analysis of the patient’s stridor, a characteristic high-pitched breathing sound that often accompanies UAOs.
