Filter by: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
Sleep apnea is a common sleep disorder characterized by temporary stops in breathing during sleep and has been associated with the development of cardiovascular disease. This research will investigate one potential mechanism leading to the development of cardiovascular disorder, specifically, the blockage of blood vessels called "vascular occlusion", in subjects with sleep apnea. A group of healthy controls will be used for comparison. All subjects will undergo clinical evaluation followed by an overnight sleep study and a morning blood draw. Subjects with sleep apnea will be treated according to standard clinical management and followed under the research protocol for one month. At the end of one month, a repeat blood draw will be performed on the sleep apnea subjects for comparative analysis. If a control subject is found to have any abnormality during this research study, he or she will be referred for further clinical evaluation.
This trial will test the hypothesis that the 6 minute walk test (6MWT) is not reproducible as a measure for oxygen desaturation.
Subjects undergoing elective ERCP and EUS will receive standard monitoring and sedation. In addition, capnography which measures carbon dioxide levels and can graphically assess respiratory activity will be used. Subjects will be randomized to either a capnography blinded or titration arm. In the capnography titration arm, the endoscopy team would be made aware of capnographic abnormalities as they arise throughout the procedure. In the capnography blinded arm, this information will not be available to the endoscopy team and represents standard of care. It is our hypothesis that using capnography can prevent low oxygen levels known as hypoxemia, during these procedures.
Critically ill patients are predisposed to oxyhaemoglobin desaturation during intubation. For the intubation of hypoxemic patients, preoxygenation using non invasive ventilation (NIV) is more effective at reducing arterial oxyhaemoglobin desaturation than standard method. Objectives: To find out whether NIV, as a preoxygenation method, is more effective at reducing the degree of organ dysfunction/failure than standard preoxygenation during the week following endotracheal intubation.
