Disordered breathing and oxygen desaturation during daytime naps.

J W Wynne, A J Block, L A Hunt

    The Johns Hopkins Medical Journal
    |July 1, 1978
    PubMed
    Summary

    Patients with chronic obstructive pulmonary disease (COPD) frequently experience disordered breathing and oxygen desaturation during naps. While individuals without COPD also showed disordered breathing, it was less severe and less common.

    Area of Science:

    • Pulmonary Medicine
    • Sleep Medicine
    • Respiratory Physiology

    Background:

    • Chronic obstructive pulmonary disease (COPD) is a progressive lung disease.
    • Sleep disturbances and breathing abnormalities are common in COPD patients.
    • The impact of daytime naps on breathing and oxygenation in COPD is not fully understood.

    Purpose of the Study:

    • To investigate the occurrence of disordered breathing and oxygen desaturation during daytime naps in patients with and without COPD.
    • To compare the frequency and severity of these events between the two groups.

    Main Methods:

    • Prospective observational study.
    • Inclusion of 20 participants: 10 with diagnosed COPD and 10 healthy controls.
    • Monitoring of breathing patterns and oxygen saturation levels during monitored daytime naps.

    Main Results:

    • Disordered breathing events were frequently observed during naps in patients with COPD.
    • These breathing events in COPD patients were often accompanied by significant oxygen desaturation.
    • Disordered breathing occurred less frequently and with less severe desaturation in non-COPD participants.

    Conclusions:

    • Daytime naps can precipitate disordered breathing and oxygen desaturation in COPD patients.
    • These sleep-related breathing abnormalities may contribute to nocturnal hypoxemia in COPD.
    • Further research is warranted to explore the clinical implications and management strategies for nap-related respiratory events in COPD.
