Nasal oxygen therapy did not improve cognitive function in men who snore heavily. While it improved oxygen levels, it did not reverse nocturnal hypoxemia or enhance neuropsychologic performance.

Area of Science:

  • Sleep Medicine
  • Pulmonology
  • Neuropsychology

Background:

  • Heavy snoring is often associated with nocturnal hypoxemia.
  • Hypoxemia during sleep can potentially impact cognitive function.

Purpose of the Study:

  • To investigate if nasal oxygen therapy can reverse nocturnal hypoxemia.
  • To assess the effect of nocturnal oxygen on neuropsychologic function in heavy snorers.

Main Methods:

  • A double-blind, crossover study involving 17 asymptomatic heavy snorers.
  • Participants received either nocturnal air or oxygen (2 L/min) for one month each.
  • Neuropsychologic testing was conducted before and after each treatment month.

Main Results:

  • Oxygen therapy improved oxygenation during screening but did not improve obstructive sleep apnea.
  • No significant benefits were observed in neuropsychologic function after one month of nocturnal oxygen therapy.

    • Conclusions:

    • Nocturnal nasal oxygen therapy at 2 L/min does not improve neuropsychologic function in men who snore heavily.
    • The study suggests oxygen therapy is not an effective intervention for cognitive deficits related to heavy snoring.
