Pulse oxygen saturation (SpO2), mean arterial pressure (MAP) and heart rate (HR) of aged patients. The SpO2 during EGD under sedation was higher in the airway group than in the mouthpiece group among aged patients (*P < 0.001). MAP and HR between the airway group and the mouthpiece group showed no difference (P > 0.05)
