Functional Residual Capacity
*** Define TV ***
The amound of air that moves into or out of the lungs in quiet respiration, about 500mL
The additional amount of air that can be inhaled after a normal quiet inspiration.
*** Define ERV ***
The additional amount of air that can be exhaled after quiet expiration.
The amount of air left in the lungs after a maximal forced expiration.
The total amount of air lungs can contain.
*** Define VC ***
The amount of air in the lungs that can be exhaled after a maximal forced inspiration.
- The amount of air in the lungs that can be inhaled after a quiet exhalation.
- Its the sum total of tidal volume and inspiratory reserve volume.
The amount of air left in the lungs after a quiet expiration. It is the sum of expiratory reserve volume and residual volume.
Maximum voluntary expiration
***What is the Formula for Vital Capacity and how is it measured?***
- VC = TV + IRV + ERV
- Measurement is the difference between forced inhalation and forced exhalation
*** How is Expiratory Reserve Volume measured? ***
Measurement is the difference between quiet exhalation & forced exhalation.
