Supraglottic jet oxygenation and ventilation flow diagram. A total of 102 patients with BMI > 30 receiving hysteroscopy were randomly divided into three groups: the mask oxygen group (control group) maintaining oxygen absorption via face mask (N = 33), the WNJ oxygen group maintaining oxygen absorption via WNJ(N = 33) and the WNJ SJOV group maintaining SJOV via WNJ(N = 34). One patient in the control group was excluded because of stuffy nose due to a cold(N = 1). The other patient in WNJ oxygen group was abandoned intervention due to change of the operative mode during operation(N = 1)
