The Performance of Two Oxygen Delivery Devices Used After General Anesthesia.
The Performance Comparison of Two Oxygen Delivery Devices [Nasal Cannula and Mask] Used After General Anesthesia.
After general anesthesia, there are the risks for airway obstruction, hypoventilation, atelectasis, ventilation-perfusion mismatch, hypercarbia and hypoxemia,so oxygen supplement in PACU seems necessary.
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.
