Efficacy and safety of remimazolam tosylate for sedation during upper gastrointestinal endoscopy: study protocol for a multicenter randomized controlled trial

Table 3 Perioperative respiratory-related adverse events and treatment records

SpO₂ before the procedure (no oxygen)		Lowest SpO₂ during the procedure		Is SpO₂ <90% during the procedure?	Yes □ No□
Duration of SpO₂ <90%		Did oxygen flow increase during the procedure?	Yes □ No □	Is the patient's mandible lifted?	Yes □ No□
Is mask ventilation required?	Yes□ No□			Is endotracheal intubation performed?	Yes □ No □

Treatment of respiratory-related adverse events: When SpO₂ is <95%, the participant will be lifted to the mandible. If SpO₂ is <90%, the oxygen flow of the nasal catheter will be increased to 6L/min. If SpO₂ is still <90%, the procedure will be stopped, the upper gastrointestinal endoscope will be pulled out, and positive pressure ventilation will be performed using a mask. If SpO₂ cannot be corrected, laryngeal mask airway or tracheal intubation will be performed to control breathing
