Sleep Quality Monitoring based on Sleep Stage, Vital Sign, and PSQI

Proper sleep activity is necessary for the body's recovery process to function optimally. Sleeping time in late adolescence (17–25) years old according to the age category determined by the Ministry of Health of the Republic of Indonesia (2009) takes 7–8 hours every day. Most groups at this age often experience sleep disturbances, such as insomnia, waking up frequently at night, tending to wake up later, and others. The research developed aims to monitor the sleep quality of late adolescents using a series of measurements of biological signals such as sleep stages and vital signs. The vital signs measured are heart rate (HR), SpO2, MAP (mean arterial pressure), and blood pressure. The results will be compared with a qualitative evaluation of the Pittsburgh Sleep Quality Index (PSQI). Biological data is collected using a system consisting of a smartwatch commercial device and an android mobile app. To support the system analysis, 10 respondents were asked to use the developed system within 3 days and fill out the PSQI digital questionnaire. Comparative evaluation of biological data results and PSQI results can be done by giving a score based on each measurement. Scoring results from biological data, all respondents had poor sleep quality even though all vital signs showed in good condition. When compared to the PSQI results, there were 4 people who stated that their sleep quality was good and the rest scored very poorly. This suggests that only about 60% of PSQI results correspond to sleep stages when vital signs are ignored. The use of commercial tools for sleep quality can be used if we use other tools to support them in making decisions about their sleep quality.
