Easy airway: unassisted mask ventilation, ventilation without the need for an airway, achieving oxygen saturation above 90% during mask ventilation, and unassisted intubation with less than three attempts.

Difficult airway: assisted mask ventilation, need for airway during ventilation, oxygen saturation falling below 90% during mask ventilation, assisted intubation, intubation attempt three and above

The STOP-Bang Questionnaire is intended to give physicians an easy-to-use tool to identify people who might have obstructive sleep apnea (OSA). The questionnaire consists of eight yes-or-no questions based on the major risk factors for OSA. A STOP-Bang score of 2 or less is considered low risk, and a score of 5 or more is high risk for having either moderate or severe OSA. For people who score 3 or 4, doctors may need to perform further assessment to determine how likely they are to have OSA.
