WebThe Normal Range of Wedge Pressure. The nor- mal range of wedge pressure reported in the literature is from 0 to 11.2 mm. Hg above the right atrium [1,3-5]. Our own results in a limited number of "normal" patients suggest that wedge pressure is probably seldom more than 5 to 6 mm. Hg higher than vena caval pressures.
