Summary Introduction

To review:

Match the hemodynamic parameter, that is, the mean pulmonary artery pressure with the most closely related normal range from the options given below.

a) 4-8 L/min

b) 800-1500 dynes $\times$ sec $\times$ cm^-5

c) 60-130 mL

d) 2-8 mm Hg

e) 20-120 dynes $\times$ sec $\times$ cm^-5

f) 9-18 mm Hg

g) 30-65 mL/beat/m²

h) 80 mm Hg

i) 2.5-4.2 L/min/m²

j) 4-12 mm Hg

k) 40-60 g m/m²

l) 7-12 g m/m²

Introduction:

Hemodynamic status of a person is determined on the bedside itself. It is checked to determine the circulation of blood flow inside the body. It is measured with a pulmonary artery catheter. Hemodynamic status includes right atrial pressure (RAP), central venous pressure (CVP), mean pulmonary artery pressure, cardiac output, and pulmonary capillary wedge pressure (PCWP).

Explanation of Solution

Pulmonary hypertension is a condition in which the mean pulmonary arterial pressure increases. The normal range of mean pulmonary artery pressure is 9-18 mm Hg (millimeter of mercury). When the range reaches above 25 mm Hg, it is known as pulmonary hypertension. This arises as a complication of the pulmonary or cardiac disease.

Conclusion

Therefore, it can be concluded that the mean pulmonary artery pressure can be correctly matched with option (f).
