respiratory volumes and capacities
Cards (20)
- The tidal volume is the volume of air inspired during normal breathing.
- inspiratory reserve volume is the maximum additional volume of air that can be inspired by a forcible inspiration
- expiratory reserve volume is the additional volume that can be exhaled beyond tidal volume when needed, such as during coughing or sneezing (forcible expiration).
- value of erv1000 ml to 1100 ml
- residual volume is the amount of air remaining in the lungs at the end of a forcible expiration. It cannot be voluntarily exhaled.
- value of rv1100 ml to 1200 ml
- value of irv2500 mL to 3000 mL
- inspiratory capacity is the total amount of air that can be inspired into the lungs after a normal expiration
- value of ic3000 ml to 3500 ml
- expiratory capacity is the total volume of air a person can expire after a normal inspiration
- value of ec1500 ml to 1600 ml
- functional residual capacity is the volume of air that remains in the lungs after a normal expiration
- frc= erv + rv
- ec= erv + tv
- vital capacity is the maximum volume of air a person inspire after a forceful expiration
- vc= erv + tv + irv
- value of frc2100 ml to 2300 ml
- total lung capacity is the total volume of air in the lungs at the end of a forceful inspiration
- tlc= rv + erv + irv + tv
- value of tlc5100 ml to 5800 ml
