The Phase Analyses on the SaO2 variations in SAS

For the phase analyses, we defined T
1
, and T
2
as the delayed times for the patients who suffered with sleeping apnea syndrome (SAS), from which we can find the relationships between gas inhalation and SaO
2
(saturation level of oxygen). The results indicated that the hemoglobin contents and the amounts of red blood cells are some what in accord with the delayed time T
2
and the AHI (Apnea and Hypopnea Index) of SAS patients.
