Hypoxemia Clinical Trial
Official title:
The Effect of Different Oxygen Delivery Methods of Nasal Catheter on the Incidence of Hypoxemia in Patients With High Risk of Hypoxia During Painless Gastroscopy
In this study, patients undergoing painless gastroscopy were selected to change the nasal catheter oxygen delivery mode to oral oxygen delivery after endoscope implantation, in order to explore the effect of this oxygen delivery mode on the incidence of hypoxemia during general anesthesia gastroscopy.
This study was a randomized controlled study in which patients undergoing elective painless gastroscopy were selected and grouped by random number table. The control group used conventional nasal cannula oxygen method: nasal cannula was used before and after gastroscopy was implanted and after withdrawing from the gastroscopy. Test group: nasal cannula nasal oxygen before gastroscopy placement, nasal cannula oxygen delivery after gastroscopy placement, nasal cannula nasal oxygen delivery after exit gastroscopy, nasal cannula nasal oxygen after exiting gastroscopy. The incidence of intraoperative hypoxemia was observed. ;
