Recognize a list of conditions which can be assessed with the measurement of all lung volumes and capacities correct answer: A. FRC - (functional residual capacity) 1. volume of gas remaining in the lungs at the end of a quiet breath 2. AKA resting expiration level - normal exhalation. *3. RV (residual volume) - is the volume of gas remaining in the lungs at the end of a maximal expiration, regardless of the lung volume at which exhalation was started 4. An important diagnostic tool in ...
