Impact of different hypopnea definitions on obstructive sleep apnea severity and cardiovascular mortality risk in women and elderly individuals

Sleep Study and Oximetry Parameters for Predicting Postoperative Complications in Patients With OSA

“…The North American AASM criteria allow for two differing scoring methods for hypopneas. 23,52 The criteria for decrease in oxyhemoglobin desaturation can be > 3% or 4%, which can result in variability in the AHI. Details about the type of oximeters used to determine the oxygen parameters often were not provided.…”

Sleep apnea in relation to metabolism: An urgent need to study underlying mechanisms and to develop novel treatments for this unmet clinical need

“…OSA is a relatively common problem with about 20% of adults presenting with at least mild OSA and about one in 15 presenting with moderate or severe OSA [3]. OSA often occurs as a comorbidity of obesity and DM, but it also contributes to worsening of DM, at least in part independently from obesity, and leads to increased morbidity and mortality from DM, cardiovascular disease, and accidents caused by excessive daytime sleepiness [4–7]. Indeed, the risk of OSA increases with both age and BMI with a prevalence of up to 80% in the highest risk categories [8] for this unmet clinical need.…”

The effects of undiagnosed nocturnal hypoxia on the intensive care unit admission scores

“…Yet, the different hypoxia definitions in OSAS have been still discussed [19] . In the present study, we didn't find any relationship between AHI and each of CCI, APACHE II score and length of hospital stay (r 2 =0.04 p=0.118; r 2 =0.06 p=0.068; r 2 =0.05 p=0.092 respectively).…”
