Fig. 1From: The physiologic response to epinephrine and pediatric cardiopulmonary resuscitation outcomesTiming 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-respondersBack to article page
