WebPatients were categorized into two groups for analysis, group 1: SaO 2 nadir < 75%, and group 2: T90 > 20%. Results: Of the 365 patients, 163 (45%) recorded SaO 2 nadir < 75% and 127 (35%) recorded T90 > 20%. These oxygenation parameters were associated with more severe OSA by AHI (p < 0.001). T90 > 20% was associated with an increased risk … WebExercise for Desaturation Test. If you are doing the exercise for desaturation test, you will be asked to walk on a treadmill at a comfortable pace for a maximum of 6 minutes per exercise period. Multiple 6 minute walking exercise periods may be required. You may be asked to wear oxygen during the testing periods.

Here arises the misconception that saturation should hence fall. But these binding sites still retain their affinity for oxygen and “saturate” themselves as previously. candytoft wynd hamilton
