To answer the question whether a previously detected breath profile in patients suffering from obstructive sleep apnoea (OSA) can be found in a cohort of patients with suspected OSA using mass spectrometry (validation study).
Clinical trial in patients with obstructive sleep apnoea that are randomised to either continue or withdraw continuous positive airway pressure therapy to identify a disease-specific exhaled breath pattern by mass spectrometry.
Studies have shown high prevalence (60-94%) of obstructive sleep apnoea (OSA) among patients undergoing bariatric surgery. Fifteen studies are published investigating the effect of bariatric surgery on OSA. All of them conclude a highly positive effect on OSA by bariatric surgery and weight loss. However these studies are biased by a huge number of drop outs. The drop out rate in the studies are around 60 percent. The Investigators state that the prevalence of OSA among patients undergoing bariatric surgery in Denmark is high. The Investigators state that the effect of bariatric surgery is significant on severity of OSA. The Investigators state that we can perform a study without a huge number of dropouts.
As continuous positive airway pressure is the treatment of choice for OSA, a mask is vital in ensuring the effectiveness of therapy delivery. The study will evaluate the performance and usability of the new mask vent. This is done by comparing the apnea-hypopnea index (AHI) of patients, who will apply 2 different washing procedures to the new mask, at the end of the study and their baseline data obtained at the beginning of the study.The study will also assess the breathing comfort as well as obtaining subjective data on the usability of the new mask vent system.
