  Purpose

Respiration failure type 2 is loss of the lungs ability to take up oxygen (O2) and get rid of carbon dioxide (CO2). The diagnosis is based on blood gas measurement of pressures of O2 and CO2. Patients with COPD is often seen to have co-morbidity with cardiac diseases. Chronic systemic inflammation is seen in both COPD and cardiac diseases. The investigators will investigate the sleep quality, CO2-retention, O2-saturation, cardiac arrythmias and markers of inflammation in 120 patients with COPD in different stages of the disease. Our hypotheses are:

  • that the first signs of respiration failure type 2 is seen during sleep with alteration of sleep patterns and greater and more long-lasting retention of CO2 in the blood compared to those with a normal lung function
  • that the use of alcohol, zopiclone or supplementary oxygen will make these differences even greater
  • that cardiac arrythmias correlates with hypoxemia
  • that cardiac arrythmias and respiration failure correlates with degree of inflammation

Enrollment: 150
Study Start Date: May 2009
Study Completion Date: July 2011
Primary Completion Date: July 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1 supplementary oxygen
participant receives supplementary oxygen one night, polysomnography with capnography will be compared to no treatment another night
Drug: supplementary oxygen
Supplementary oxygen 2 L/min if SpO2 < 90%. If SpO2 < 90 % the oxygen dose is titrated until SpO2 reads 88-92%. For patients on LTOT the oxygen dose is doubled for intervention.
Other Name: 100% oxygen gas with continous flow from wall outlet
Active Comparator: 2 Zopiclone
participant receives 5 mg zopiclone one night, polysomnography with capnography will be compared to no treatment another night
Drug: zopiclone
5 mg sedative given approximately 1 hour before sleep
Other Name: Imovane, Zopiklon
Active Comparator: 3 Alcohol
participant receives 0,5 mg alcohol /kg body weight before sleep one night, polysomnography with capnography will be compared to no intervention another night
Other: alcohol
5 mg alcohol/kg body-weight approximately 1 hour before sleep
Other Name: 96% ethanol
