1

Pulmonary System Function

Exchange of O2 and CO2
Control of pH
Oral communication

2

Ventilation

Product of tidal volume and breathing frequency

3

Mild to Moderate Exercise

Ventilation is increased by tidal volume

4

Vigorous Exercise

Ventilation is increased by breathing rate

5

Light Exercise

Increased tidal volume and respiratory rate

6

70-80% of Peak Exercise

TV and RR both increase up to this point

7

>80 % of Peak Exercise

Increased RR

8

Vital Capacity

TV generally plateaus at 50-60% of VC

9

Respiratory Rate

Increases 1-3x in normal adults
Increases 6-7x in conditioned athletes

10

Anaerobic Threshold

Lactate starts to accumulate in blood
Level above which pyruvate is produced faster than it can be used aerobically, causing exhaustion and intramuscular pain

11

Minute Ventilation

Amount of oxygen brought into lungs per minute

12

Max Inspiratory Level

Most air can take in with one single breath after normal breathing

13

Max Expiratory Level

Big deep breath in and blow all the air out

14

Vital Capacity

Max inspiratory to max expiratory

15

Residual Volume

What's left in lungs after max expiratory breath

16

Total Lung Capacity

Residual volume + vital capacity
