  • Five-point Likert scale rating: handling of equipment (very difficult to very easy), visibility during performing the procedure (very poor to very good), confidence in achieving successful intubation (not confident to very confident), degree of movement (very limited to no limitation) and perception of risk of exposure to contamination (very low to very high).
