Sleep apnea: One of the features of sleep apnea is that the oxygen level and hemoglobin-oxygen saturation (the amount of oxygen carried in the blood to the tissues) declines

Yes,: Both obstructive and central sleep apnea can lead to a decreased gas exchange in the lung through either decreased airflow or disturbed ventilation during the sleep and subsequently result in low oxygen level in blood.
