(A) Market landscape analysis comparing cost and efficacy of current solutions. Qualitative efficacy was determined from a combination of reported physician importance, intubation success rates for no more than three attempts, and efficacy reports from peer-reviewed journals. Costs were determined using medical device purchasing platforms and clinical reports. Data from these studies.50,52,61–67 (B) Market landscape analysis comparing first-attempt success rate and cost. Note that the data used to populate first-pass success rate has studies pertaining to typical airway management as the upper bounds, and difficult airways as the lower bounds, when applicable. Data from these studies.68–76 (C) Market landscape analysis comparing time for intubation and cost. Note that times may overlap for adjunct devices and respective devices whose insertion they assist. **Indicates device with learning curve in medical trainees as indicated by literature. Data from these studies.71–74,76–79,80
