It depends on your personal therapy needs. If you need static, go with CPAP. And if it's a pressure range, go with APAP.

RE: tired and yawning
Your tidal volume is constantly varying through the night. Your body is constantly accounting for this increased and decreased airflow through the night. Respiratory rate is a little high with inhales slightly longer than exhales. Your not showing much of any events on the machine accept for flow limitation. Maybe try increased min pressure
Maybe min pressure 7, max pressure 10?
