A computer implemented method of evaluating patient candidacy for an implantation of a nerve stimulation device, the method comprising: providing sleep data to a server, the sleep data including a log of respiratory events for a sleep period of the patient, the sleep data further including blood oxygen data correlated with said respiratory events; and receiving a response from the server, the response including an indication, based on the sleep data, as to whether the patient is a candidate for the implantation of the device; and wherein the blood oxygen data correlated with said respiratory events supports a mean oxygen desaturation value, and wherein: either a) the indication is positive when the mean oxygen desaturation value is at least one of less than 3%, less than 4%, less than 5%, less than 6%, less than 7% and less than or equal to 8%, and the indication is negative when the mean oxygen desaturation value is greater than 8% or b) the indication is positive when the mean oxygen desaturation value is less than 5%, and the indication is negative when the mean oxygen desaturation value is at least one of greater than 6%, greater than 7%, greater than 8%, greater than 9%, greater than 10%, greater than 11%, greater than 12%, greater than 13%, greater than 14%, greater than 15%, greater than 16%, greater than 17%, greater than 18%, greater than 19%, greater than 20%, greater than 21%, greater than 22%, greater than 23%, greater than 24%, and greater than 25%. providing sleep data to a server, the sleep data including a log of respiratory events for a sleep period of the patient, the sleep data further including blood oxygen data correlated with said respiratory events; and receiving a response from the server, the response including an indication, based on the sleep data, as to whether the patient is a candidate for the implantation of the device; and wherein the blood oxygen data correlated with said respiratory events supports a mean oxygen desaturation value, and wherein: either a) the indication is positive when the mean oxygen desaturation value is at least one of less than 3%, less than 4%, less than 5%, less than 6%, less than 7% and less than or equal to 8%, and the indication is negative when the mean oxygen desaturation value is greater than 8% or b) the indication is positive when the mean oxygen desaturation value is less than 5%, and the indication is negative when the mean oxygen desaturation value is at least one of greater than 6%, greater than 7%, greater than 8%, greater than 9%, greater than 10%, greater than 11%, greater than 12%, greater than 13%, greater than 14%, greater than 15%, greater than 16%, greater than 17%, greater than 18%, greater than 19%, greater than 20%, greater than 21%, greater than 22%, greater than 23%, greater than 24%, and greater than 25%. either a) the indication is positive when the mean oxygen desaturation value is at least one of less than 3%, less than 4%, less than 5%, less than 6%, less than 7% and less than or equal to 8%, and the indication is negative when the mean oxygen desaturation value is greater than 8% or b) the indication is positive when the mean oxygen desaturation value is less than 5%, and the indication is negative when the mean oxygen desaturation value is at least one of greater than 6%, greater than 7%, greater than 8%, greater than 9%, greater than 10%, greater than 11%, greater than 12%, greater than 13%, greater than 14%, greater than 15%, greater than 16%, greater than 17%, greater than 18%, greater than 19%, greater than 20%, greater than 21%, greater than 22%, greater than 23%, greater than 24%, and greater than 25%. the indication is positive when the mean oxygen desaturation value is less than 5%, and the indication is negative when the mean oxygen desaturation value is at least one of greater than 6%, greater than 7%, greater than 8%, greater than 9%, greater than 10%, greater than 11%, greater than 12%, greater than 13%, greater than 14%, greater than 15%, greater than 16%, greater than 17%, greater than 18%, greater than 19%, greater than 20%, greater than 21%, greater than 22%, greater than 23%, greater than 24%, and greater than 25%.
