Fundacion CTIC General data
Fundacion CTIC (Information and Communication
Technological Centre) is a private non-profit
institution founded by the Regional Government of
the Principality of Asturias and a Consortium of
regional ICT private companies. Model public
and private participation.

• Working Areas
• Technology (standards and accessibility
  principles for web design).
• Information Society.
• Research, Development and Innovation.

RD department
In addition, some projects are also being
developed due to their importance in terms of
enabling technologies, know-how and
transversality (e.g. RFID). Other working lines
are not discarded in a near future.

Project background (1/3)

• There are a number of common sleep problems which
  are significant public health issues
• Sleep apnea.
• Chronic insomnia, narcolepsy.
• Periodic limb movements and restless legs
  syndrome.
• Moreover there are a number of chronic conditions
  where breathing during sleep is affected (e.g.
  pulmonary hypertension, ).
• In general, disorders of sleep related breathing
  are characterised by a total or partial reduction
  of breathing.
• At present, there is no widely used technique for
  measuring sleep and breathing in the home
  environment.

4
Project background (2/3)

• In clinical practice, a nasal cannula and the
  thoraco-abdominal movements by inductance
  plethysmography is the most widely used method to
  detect and to characterize the different
  breathing events.
• Talking about sleep apnea
• Prevalence.
• There are many people undiagnosed.
• Constitutes a significant public health problem.
• Actual diagnosis methods
• Gold Standard overnight polysomnogram.
• Respiratory polygraphy.

• HW integration, storage of the acquired data,
  data sending.
• Remote data analysis and management based on web
  (hospital ? user home).
• User interaction based on an interactive
  application for DTV.

Conclusions

• The non-contact biomotion sensor is a valid way
  to measure sleep parameters in the home
  environment.
• It can measure both breathing and movement
  simultaneously.
• It is low-cost and robust for users.

• The NC-prototype measures the same information as
  the thoracic-abdominal bands do (the quality of
  the NC-signal is the same that the SUM signal,
  and the NC-signal is valid in all considered
  positions).
• The NC prototype can be used as the usual method
  to detect breathing movements in polysomnography.
  New studies will be necessary in the future to
  demonstrate if the NC sensor used with a nasal
  cannula can characterize apneas, hypoapneas and
  flow limitation.

• Viable integration of the wireless NC sensor with
  iDTV (BT-Ethernet).
• Remote execution of the processing algorithms
  (SOA).
• HMI based on digital TV (user) and web platform
  (medical professionals).
