Area of Science:

  • Sleep Medicine
  • Respiratory Physiology

Background:

  • Assessing upper airway function during sleep is crucial for diagnosing sleep-related breathing disorders.
  • Existing techniques for evaluating airway mechanics during sleep have limitations.

Purpose of the Study:

  • To propose a standardized protocol for measuring critical pressure (Pcrit) during sleep.
  • To establish Pcrit as a key indicator of upper airway collapsibility.

Main Methods:

  • Utilizing the Starling resistor concept for airway pressure measurements.
  • Developing a standardized protocol for Pcrit assessment during sleep.

Main Results:

  • Pcrit quantifies upper airway collapsibility during sleep.
  • Literature data demonstrates the impact of interventions like weight loss and surgery on Pcrit.

Conclusions:

  • Measurement of Pcrit offers a standardized approach to assess upper airway collapsibility.
  • Implementing Pcrit measurement in clinical practice can guide therapeutic decisions for sleep-related breathing disorders.
