| Research Abstract |
Sleep depth is typically assessed by polysomnography ; however, the method is not easy to use for either subjects or researches. Therefore, we conducted this research to develop an algorithm for assessing sleep depth using power spectral indices of heart rate variability data. As a result, the agreement rate between polysomnography and our method was 56% for data obtained from a group of healthy women. The accuracy was lower when the algorithm was used for data from senior and young people who have sleep problems. A further refinement is necessary before our sleep assessment method will be ready for application.
