There May Be a Reversal of the Usual Relationship of Simultaneous Recordings of Radial and Aortic Blood Pressures (Prebypass) in the Early Period after Separation from Cardiopulmonary Bypass (Postbypass)

There may be a reversal of the usual relationship of simultaneous recordings of radial and aortic blood pressures (prebypass) in the early period after separation from cardiopulmonary bypass (postbypass).
