Can sleep apnea cause low oxygen level?

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.
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.
