Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study aim is to compare the two methods of oxygen supplement which are 1.nasal cannula at O2 flow 4 L/min. 2.oxygen mask with O2 flow 5 L/min. The hypothesis in this study is the 2 methods can equally provide effective oxygen supplement to prevent anesthesia-related hypoxemia. Choosing nasal cannula would be reasonable because it is cheaper and more comfortable to patient.
