What is the normal range for wedge pressure?

Explanation:
Wedge pressure reflects left-sided filling pressure and serves as an estimate of left atrial pressure and LV preload. In healthy individuals, this pressure is typically in the low teens, with many texts citing about 6–12 mmHg; some sources use a broader window of roughly 5–15 mmHg to account for variability in measurement and individuals. So, the range around 5–15 mmHg is the best choice because it aligns with the general normal spectrum for wedge pressure, while values below about 5 mmHg suggest underfilling or measurement error and values above about 15 mmHg indicate elevated left-sided pressures, as seen in conditions like heart failure or volume overload.
