Figure 32-32 Temporal relationships between normal systemic arterial pressure (ART), pulmonary artery pressure (PAP), central venous pressure (CVP), and pulmonary artery wedge pressure (PAWP). Note that the PAWP a-c and v waves appear to occur later in the cardiac cycle than do their counterparts on the right side of the heart seen in the CVP trace. The ART scale is on the left, and the PAP, CVP, and PAWP scales are on the right. (Redrawn from Mark JB: Atlas of Cardiovascular Monitoring. New York, Churchill Livinstone, 1998, Fig. 3-3.)
