Echocardiography Techniques II Exam 1 Practice

Mean left atrial pressure reflects the left-sided filling pressure and is typically around 8–12 mmHg in a resting state, with 10 mmHg often cited as a representative mean value in standard references. The value mentioned in this context is 10 mmHg, which fits squarely as that commonly used average. This is why it’s the best choice: it embodies the typical mean LAP used as a reference for normal filling pressures and diastolic function assessment. Wedge (PAWP) pressure obtained during right heart catheterization approximates the left atrial mean pressure in stable conditions, linking this value to practical measurements. The other options either describe a lower end or a broad range, rather than the specific mean value highlighted in the material.
