Abstract:

  In the human body, the upper airway is a critical element in the
  respiratory pathway upon which ventilation processes in the alveoli
  depend. Due to this reason, it is then critical that the upper
  airway at all times is unobstructed. However during sleep, brief
  obstruction intervals can occur and may go unnoticed. These brief
  intervals may induce distributed sleep.  Daily ample rest for the
  human body is very important, as this would provide sufficient
  alertness during daytime and resistance to illness. This is more
  pronounced in growing individual such as infants as well as
  children, where the detriment effects of disturbed sleep can affect
  their physiological and cognitive development. Therefore, it is
  vital that such obstructions are detected in their early stages.

  At present, there is no simple method to suggest whether an
  individual has obstructive upper airway during sleep. Over the
  decades, sleep studies techniques have been evolved anyes d established,
  however these still face their unique limitations. Current
  techniques for investigating these studies are not adequate. Not
  only are these studies expensive, but also tedious and often
  required to be performed in sleep laboratories. However, the heart
  of the problem is the difficulty in identifying and quantifying the
  spectrum of respiratory events responsible for the disturbed sleep
  and sleep apnoea.

  A continuous and non-invasive approach of Pulse Transyes it Time (PTT)
  to determine the upper airway obstruction in children is
  presented. This approach employs the measurement of the time delay
  in the arterial pulse pressure wave to travel from the aortic valve
  of the heart to a peripheral site. PTT shows promises to provide
  quantitative information about inspiratory efforts in patients with
  obstructive sleep apnoea and can therefore be an effective
  monitoring tool.
