Abstract
This invention is a method, and device, suitable for use without professional medical supervision, for screening for sleep apnea. All elements of the device are housed in a small, flexible, plastic housing which is placed on the user's philtrum. A thermistor acquires data describing the respiratory pattern. A processor analyzes the respiratory pattern in real time and outputs a study result, describing the occurrence of any episodes of apnea, to a non-volatile colored marker on the plastic housing. A flashing LED display informs the user when placement of the device is appropriate. A lithium battery, which powers all elements of the device, is activated by a pull-tab removed by the user.
