Calculate Plasma Volume



Formula

The formula to calculate the Plasma Volume is:

\[ \text{PV} = \frac{\text{Hct} \cdot \text{TBV}}{1 - \text{Hct}} \]

What is Plasma Volume?

Plasma volume refers to the amount of plasma, the liquid component of blood, circulating in the body. Plasma makes up about 55% of total blood volume and is composed primarily of water, but also contains proteins, glucose, clotting factors, electrolytes, hormones, carbon dioxide, and oxygen. It plays a crucial role in maintaining blood pressure and regulating body temperature.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \text{PV} = \frac{0.45 \cdot 5000}{1 - 0.45} \approx 4090.91 \, \text{mL} \]

The Plasma Volume (PV) is approximately 4090.91 mL.
