Do T90 and SaO2 nadir identify a different phenotype in obstructive sleep apnea?

CONCLUSION: The findings demonstrate a correlation between SaO2 nadir < 75% and T90 > 20% and increased severity of OSA. The findings also show a strong association between SaO2 nadir < 75% and T90 > 20% and increased risk for comorbidities of HT and T2DM as well as mortality at 5 years. This analysis suggests that parameters of oxygenation should be used to describe a high-risk phenotype of OSA. PMID: 31081538 [PubMed - as supplied by publisher]
