NCT04711083

Brief Summary

Nocturnal reduction in blood oxygen is expected independently associated with the development of worsened glycemic control in individuals with type 2 diabetes mellitus. The aim of the present study is to assess the correlation between nocturnal oxygen desaturation assessed by overnight pulse oximetry and glycemic control in diabetic patients with obstructive sleep apnea.

Outcome Measures

Primary Outcomes (1)

  • correlation between nocturnal oxygen desaturation and glycemic control

    measurements of blood glucose control and nocturnal oxygen level.

    1 year

Interventions

Wrist worn Overnight oximetry was performed using portable Nonin 2500 (Nonin Medical Inc., USA) pulse oximeters. The test was explained to the subjects and their caregiver by experienced health-care staff from the sleep unit. The recording was done at home and started just before going to bed and ended on awakening; the recommended duration was a minimum of 5 h and a maximum of 7 h. The awake SpO2, mean SpO2. The data were analysed to calculate the overnight minimum SpO2, mean SpO2, dip frequency (defined as a fall in SpO2 of \> 4%), the percentage of oximetry sleep time spent with a SpO2 of \< 90%, and the total oximetry time. Recordings were classified as "normal" (\< 4.9 desaturation events an hour), "equivocal" (5 to 14.9 desaturation events an hour), or "abnormal" (\> 15 desaturation events an hour) according to the severity and pattern of nocturnal desaturation observed .
