SECONDARY outcome

Timeframe: Every 30 seconds during sedation; this is on average 30 minutes (range 10-240 minutes)

While there were 77 patients per group, each patient had vital signs measured every 30 seconds for the duration of their stay. This resulted in a variable amount of time points (data points) recorded per patient. Our event frequency was the number of events (outcome measure of abnormal vital signs) per number of time points for each patient. This is presented as an event rate.
