Timing of blood pressure sampling. Figure depicts timing of blood pressure sampling relative to epinephrine administration. For this theoretical patient who received epinephrine two minutes into CPR, the 30-s data epochs of that minute of CPR (e.g., 90 s through 150 s) are considered the epinephrine administration period and not included in blood pressure analyses. The immediately preceding 30-s epoch (e.g., 60 s through 90 s) is utilized for pre-epinephrine BP determination. If unavailable, the prior is used (e.g., 30 s through 60 s). The mean BP from the four post-epinephrine epochs following the epinephrine administration period (e.g., minutes 2.5 through 4.5) are utilized for post-epinephrine BP determination. The difference between the mean DBP from this 2-min period and the mean DBP from the pre-epinephrine epoch was used to classify patients as epinephrine responders or non-responders
