What is the functional residual capacity in milliliters?

Functional residual capacity (FRC) is a key respiratory parameter representing the volume of air that remains in the lungs after a normal expiration. This capacity is crucial for understanding lung function and assessing respiratory health.

The normal range for functional residual capacity for an adult is typically around 2400 mL to 3000 mL, depending on factors such as body size and health status. The value of 2400 mL aligns perfectly with the typical average for many adults, making it a cornerstone figure in pulmonary physiology.

Understanding FRC helps perfusionists and medical professionals gauge not only lung mechanics but also the effect of certain conditions and treatments on lung function. Therefore, selecting 2400 mL as the functional residual capacity reflects an accurate understanding of this vital lung measurement.
