Mean blood pressure (MBP) was calculated from systolic and diastolicpressures for the 5 patients (P₁–P₅). MBP was measured before Ado infusion (time 0), and then every 2 min for the next 10 min, except in P₃ in which a 10 min MBP was not obtained. Ado infusion caused MBP to decrease at some point during the infusion in all subjects, but the pressure did not decrease below 69 mmHg in any of the subjects.
