Total Lung Capacity (TLC) = Inspiratory Reserve Volume (IRV) + Tidal Volume (TV) + Expiratory Reserve Volume (ERV) + Residual Volume (RV)
Vital Capacity (VC) = Inspiratory Reserve Volume (IRV) + Tidal Volume (TV) + Expiratory Reserve Volume (ERV)
Inspiratory Capacity (IC) = Tidal Volume (TV) + Inspiratory Reserve Volume (IRV)
Functional Residual Capacity (FRC) = Expiratory Reserve Volume (ERV) + Residual Volume (RV)
Determining Lung Capacities Values are calculated for an individual patient based on variables such as height, weight, sex, and age. A value is usually considered abnormal if it is less than 80% of the reference value
Tidal Volume = 500 mL
Expiratory Reserve Volume = 1000 mL
Vital Capacity = 4000-5000 mL
Inspiratory Capacity = 3000-4000 mL; 75-80% of vital capacity; 55-60% of total lung capacity
Forced Expiratory Volume in one second (FEV1) = 83% of VC
Forced Expiratory Volume in two seconds (FEV2) = 94% of VC
Forced Expiratory Volume in three seconds (FEV3) = 97% of VC

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
