Abstract
Embodiments include a screening method for evaluating patient suitability for an implanted hypoglossal nerve stimulation (HGNS) device. The screening method evaluates blood oxygen data relating to respiratory events, with the blood oxygen data providing mean blood oxygen desaturation values for comparison to severity thresholds to identify patients who are likely or unlikely to benefit from the implantation of the HGNS device.
Claims56
A method of evaluating and treating a patient using a nerve stimulation device, the method comprising:
- receiving, by a server, preconditioned sleep data for analysis, the sleep data including a log of respiratory events for a sleep period of a patient, the sleep data further including blood oxygen data correlated with said respiratory events, wherein the blood oxygen data supports a mean oxygen desaturation value and an oxygen desaturation distribution curve, plotted against desaturation rate, having a slope between two points on the curve;
- comparing, by the server, at least one of the mean oxygen desaturation value or the slope of the oxygen desaturation distribution curve with a threshold;
- determining, by the server, that the at least one of the mean oxygen desaturation value or the slope of the oxygen desaturation distribution curve is below the threshold;
- providing, by the server, an indication that the patient is a candidate for the implantation of the nerve stimulation device to be displayed to a user via a user interface, the indication being based on the determination that the at least one of the mean oxygen desaturation value or the slope of the oxygen desaturation distribution curve is below the threshold;
- implanting the nerve stimulation device within the patient based on the indication;
- and
- delivering nerve stimulation therapy to the patient via the nerve stimulation device.
