Right atrial pressure meaning
WebSep 11, 2024 · The relationship between unstressed and stressed blood volume and mean systemic pressure ( Pms) and its independence from mean arterial pressure ( MAP) and right atrial pressure ( Pra ). Pra is important because the driving pressure for venous return ( Pvr) is the pressure difference between Pms and Pra. WebRight-Atrial Waveform The normal right-atrial pressure is 2–6 mmHg and is characterized by a and v waves and x and y descents ( Fig. 2.4 ). The a wave represents the pressure rise within the right atrium due to atrial contraction and follows the P …
