Table 1.
Respondent demographics and rapid sequence induction (RSI) usage by analysis subset. Categorical variables are summarized as percentages and counts (if missing data were present, then denominators are also provided) while continuous variables are characterized by the 10, 25, 50 (median), 75 and 90th percentiles.

Gate restrictions correspond to survey items 8–11 (Appendix), while gate and follow-up restrictions correspond to both survey items 8–11 along with the additional items related to each item. For example, the gate question for Item 9 is “In preparation for a modified RSI, do you usually preoxygenate prior to induction?” while the follow-up items investigate oxygen administration durations.
