SJOV in hysteroscopic surgery

This study investigates whether Supraglottic Jet Oxygenation and Ventilation (SJOV) can prevent hypoxemia during hysteroscopic surgery，and this single-center, randomized controlled trial demonstrates that the proactive application of SJOV using the Wei nasal jet tube is significantly more effective than standard nasal cannula oxygenation in maintaining oxygenation during hysteroscopic surgery under sedation. In the table, N represents the use of nasal cannula oxygen therapy, and S represents the use of SJOV (Surgical Jaw Opening Ventilation) therapy. In the sheet “N Group”, cell BG34 indicates that the patient in row 34 experienced intraoperative hypoxemia (75% ≤ SpO? < 90%) 3 times. Cell BF34 refers to the lowest SpO? value among these three hypoxemic episodes. Cell BH34 refers to the duration (in seconds) of each of these three hypoxemic episodes. Other cells follow the same logic.
