Functional residual capacity - Wikipedia
Functional residual capacity (FRC) is the volume of air present in the lungs at the end of passive expiration. [1] At FRC, the opposing elastic recoil forces of the lungs and chest wall are in equilibrium and there is no exertion by the diaphragm or other respiratory muscles.

2022年12月26日 · Functional residual capacity (FRC) is the volume remaining in the lungs after a normal, passive exhalation. In a normal individual, this is about 3L. The FRC also represents the point of the breathing cycle where the lung tissue elastic recoil and chest wall outward expansion are balanced and equal.
Functional Residual Capacity (FRC): An Overview (2024)
2024年9月24日 · What is Functional Residual Capacity? Functional residual capacity (FRC) is the volume of air remaining in the lungs after a normal, passive exhalation. It’s a critical measurement in respiratory physiology, combining expiratory reserve volume (ERV) and residual volume (RV).
Functional Residual Capacity Tests and Lung Function
2022年6月26日 · Functional residual capacity (FRC) is the volume of air left in your lungs after a normal, passive exhalation. This test is used to evaluate your lung function, and you may need to have your FRC measured before lung surgery or if you have a lung disease such as emphysema or chronic obstructive pulmonary disease (COPD) .
Functional Residual Capacity - an overview - ScienceDirect
Functional residual capacity (FRC) is the lung volume at the end of normal expiration. It is significantly reduced in the anaesthetized patient, and, depending on factors such as position (e.g. head down), obesity, late pregnancy, and restrictive …

Functional Residual Capacity - an overview - ScienceDirect
Functional Residual Capacity refers to the volume of gas remaining in the lungs after normal exhalation. It decreases by about 20% during sleep and anesthesia, leading to potential issues with gas exchange, especially in older or obese individuals.
