A positive ESAP (easy sleep apnea predictor) is defined as the failure to encircle the neck using hand grasp with a 1cm gap between fingers (Figure 1).
High-risk berlin questionnaire is 2 or more positive categories on the screening questionnaire.
§A positive neck circumference was >16 inches in females and > 17 inches in males.
