These results underline the importance of developing the assessment of OSA severity beyond the AHI.Parameters considering characteristic properties of desaturations have a significant association with impaired vigilance, highlighting the importance of developing methods beyond the AHI for a more detailed assessment of OSA severity http://bit.ly/2veqxD9 %U //www.qdcxjkg.com/content/erj/55/4/1901849.full.pdf
