Time Frame |
---|---|---|
Correlation of POCUS measurements with AHI and/or STOP-Bang Scores
Time Frame: 1 day
|
The study is designed to assess if there is a correlation of one or a combination of point-of-care-ultrasound measurements with the severity of OSA as denoted by apnea-hypopnea index (AHI) from previous sleep study and/or STOP-Bang scores noted for the presence of OSA in screening exam prior to surgical procedures that require intubation. STOP-Bang denotes Snoring, Tired, Observed (anyone observed you stop breathing), Pressure (high blood pressure), Body mass index (more than 35 kg/m2), Age (older than 50), Neck size, Gender |
