Abstract: Techniques for automated titration of CPAP device for a subject include receiving multiple ultrasound images representing a cross section of an airway in a neck of the subject at corresponding different times. Multiple different positive pressure values imposed by a device on the airway of the subject are also received at each of the corresponding times. For each of the ultrasound images, a mask of pixels associated with an air-tissue interface is automatically formed, and a value of a statistic of pixels within the mask is automatically determined. A titration pressure for a continuous positive airway pressure (CPAP) device is automatically determined based on the positive pressures and the value of the statistic for each of the ultrasound images. Output data that indicates the titration pressure for the CPAP device is presented on a display device, such as by operating the CPAP device itself at the titration pressure.

Abstract: A method and system detects a hypoxic condition during an obstruction of an airway of a subject to detect and treat obstructive sleep apnea (OSA) in the subject. The method and system includes an organ stimulating transducer configured for placement in a vicinity of an organ of the subject to stimulate the organ and remove the obstruction when OSA is detected.

Abstract: Techniques for ultrasound location of obstructions during OSA include an ultrasound transducer array configured, upon receipt of a signal, to obtain first data that supports a plurality of ultrasound images representing a corresponding plurality of cross sections of an airway in a neck of a subject. Second data is received automatically on a processor, from an apnea event sensor set that is configured to collect automatically the second data sensitive to an apnea event in the subject. An apnea event is detected automatically on the processor based on the second data. In response to detecting the apnea event, the signal is automatically sent to the ultrasound transducer array, wherein the signal is the signal that causes the ultrasound transducer array to obtain the first data. Image data based on the first data is automatically stored in a computer-readable medium.
