Table 2.

AoS indicates aortic systolic pressure; AoD, aortic diastolic pressure; RAD, right atrial diastolic pressure; CPP, coronary perfusion pressure; ET CO₂, end tidal carbon dioxide. Depth 33 (D33) and Depth 51 (D51) refer to depth-guided CPR at 33mm and 51 mm, respectively. CPP-20 refers to CPR directed to attain coronary perfusion pressure >20 mmHg. Data presented as mean (SEM).
