Outcome Measures

Primary Outcomes (1)

  • Change in breathlessness intensity (Borg CR10) between control and intervention at iso-time

    Change between conditions in breathlessness intensity using the Borg Category Ratio scale (Borg CR10), where 0 indicates no exertion and 10 indicates maximum exertion, at iso-time (defined as the time of the latest similar time point during both conditions (control and intervention) during a constant rate cycle cardiopulmonary exercise test (CPET).

    Measured during post-control and post-intervention exercise tests, spaced 7 days to 6 weeks apart

Secondary Outcomes (20)

  • Change in breathlessness unpleasantness (Borg CR10) between control and intervention

    Measured during post-control and post-intervention tests, spaced 7 days to 6 weeks apart

  • Change in time to the limit of tolerance (tLIM) between control and intervention

    Measured during post-control and post-intervention tests, spaced 7 days to 6 weeks apart

  • Change in oxygen consumption between control and intervention (absolute)

    Measured during post-control and post-intervention tests, spaced 7 days to 6 weeks apart

  • Change in oxygen consumption between control and intervention (%pred)

    Measured during post-control and post-intervention tests, spaced 7 days to 6 weeks apart

  • Change in workload (W) between control and intervention

    Measured during post-control and post-intervention tests, spaced 7 days to 6 weeks apart

  • +15 more secondary outcomes

Study Arms (2)

Intervention: One night's sleeplessness

EXPERIMENTAL

A night without sleep. No daytime sleeping the day before the test. Participants are observed by staff at the trial unit during the night before the test.

Behavioral: One night's sleeplessness

Control: One night's normal sleep

NO INTERVENTION

A normal night's sleep (at least six hours) in the patient's home.

Interventions

A night without sleep. No daytime sleeping the day before the test. Participants are observed by staff at the trial unit during the night before the test.

Intervention: One night's sleeplessness

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age 18 years or older
  • COPD diagnosed by physician in accordance with Global Initiative For Chronic Obstructive Lung Disease (GOLD) guidelines (GOLD 2021), with a spirometric ratio of the forced expired volume in one second (FEV1) / forced vital capacity (FVC) \< 0.7 and a FEV1 \< 80% of predicted post bronchodilator at baseline.
  • Self-reported average sleep time of six hours or longer during a normal night.
  • No regular treatment with sleep medication or anxiolytics.
  • Able to cycle
  • Able to talk and write Swedish well enough to participate in the study procedures, as judged by the Investigator.

You may not qualify if:

  • Resting peripheral oxygen saturation (SpO2) \< 92%
  • Night shift worker
  • Hospitalization or clinical instability during the last four weeks
  • Treatment with supplementary oxygen at rest or during exercise
  • Sleep disturbance, defined as a Pittsburgh Sleep Quality Index \>5 at baseline
  • Contraindication to exercise testing in accordance with clinical practice guidelines (ATS/ACCP Statement on cardiopulmonary exercise testing. Am J Respir Crit Care Med 2003; 167:211-277)
  • Expected survival shorter than six months as judged by the Investigator.

CROSSOVER
Model Details: Performed in randomized order on two separate days, at least seven days apart and no more than six weeks apart. * Intervention: A night without sleep. No daytime sleeping the day before the test. Participants are observed by staff at the trial unit during the night before the test. * Control: Normal night's sleep (at least six hours of sleep) in the patient's home. The participants wear an actigraph during 48 hours before the test to ensure adherence to the allocated condition (sleep deprivation or control).
