  1. Establishment of Analysis System for Sleep Respiratory Activities Presenter：Yu-Hsiang Yen Advisior：Dr.Chun-JuHou Date：2013.10.23 睡眠呼吸活動分析系統之建立

  2. Outline • Problems and Rationale • Purpose and Specific Aims • Background and Literatures Review • Materials and Methods • Preliminary Results • References • Future Work

  3. Problems and Rationale • Sleep disorders • Taiwan Society of Sleep Medicine (2013)

  4. Problems and Rationale • Sleep Apnea • Obstructive Sleep Apnea(OSA) • Central Sleep Apnea(CSA) • Mixed Sleep Apnea(MSA)

  5. Problems and Rationale • Symptom of Sleep Apnea • Snoring :Affecting 67.9% of the general population. • Evaluation indexes • Apnea- hypopnea index AHI : • (a). 5–15/ hr = mild, • (b).15–30/ hr = moderate, • (c). > 30/ hr = severe

  6. Problems and Rationale • Physiology • Hypertension • Atherosclerosis • Coronary arterydisease • Cognitive impairments • Sudden death during sleep • Psychosis • Tired • Sleepiness • Inattention • Grumpy • Dejection

  7. Problems and Rationale • Technology for sleep measurement • PSG • Actigraphy • Oximeter Source: Philips Source: Labsystem Source: myhealthyfeeling

  8. Problems and Rationale • The global homecare respiratory market had generated 15% compound annual growth from the year of 2009 to 2015. Source:工研院 IEK (2009)

  9. Purpose and Specific Aims • To develop analysis system for sleep respiratory activities • To develop the analysis algorithm for sleep respiratory activities • To establish database management system

  10. Background and Literatures Review • Relative Thresholding With Under-Mattress Pressure Sensors to Detect Central Apnea Daphne Townsend, Student Member, IEEE, Megan Holtzman, Student Member, IEEE, Rafik Goubran, Senior Member, IEEE, Monique Frize, Senior Member, IEEE, and Frank Knoefel IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT, VOL. 60, NO. 10, OCTOBER 2011

  11. Background and Literatures Review • Moving variance • Parameter selection framework

  12. Background and Literatures Review

  13. Background and Literatures Review • Validation of Unobtrusive Pressure Sensor Array for Central Sleep Apnea Screening • Daphne Townsend, Student Member, IEEE, Rafik Goubran, Fellow, IEEE, Frank Knoefel, and Judith Leech • IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT, VOL. 61, NO. 7, JULY 2012

  14. Background and Literatures Review • ANTHROPOMETRIC INFORMATION FOR STUDY PARTICIPANTS

  15. Background and Literatures Review • Block diagram of prevalidation work

  16. Background and Literatures Review

  17. Materials and Methods • System Architecture

  18. Materials and Methods • Event tagging • PSG data • Pressure sensing data

  19. Materials and Methods • Signal processing(49 channel)

  20. Materials and Methods • Signal proccessing(Matlab)

  21. Materials and Methods • Tagging Resipiratory event (PSG)

  22. Materials and Methods • Resipiratory event report

  23. Materials and Methods Apnea Type • Database(MSSQL) Medical Information Pressure Signal& DateTime Database Device Imformation Body Movement

  24. Materials and Methods • Database(MSSQL) Medical Information Device Imformation Pressure Signal Body Movement Apnea Type

  25. Preliminary Results • Basic data of 40subjects

  26. Preliminary Results

  27. Preliminary Results • Right lying Central sleep apnea(Pressure sensing signal vs PSG)

  28. Future Work • Establishment of analysis algorithm • Signal fusion • Feature extraction • Database management system • Create table
