TODAY- LESSON 6:

SPIROGRAMS:

Vital capacity

lung volume

residual volume

Spirograms:

• When we breathe air moves into and out of our lungs.
• We can measure how much air moves at a time and put these measurements into a graph.
• These graphs are called Spirograms.
• Take a look at the next slide.

Important words:

You do not need to know all the words in the graph only the most important ones.

• Vital capacity
• Residual volume
• Total lung Capacity
• Tidal volume

Vital Capacity:

• The maximum amount of air you can move with one large inhalation  followed by a large exhalation.
  
• How much is this person's vital capacity?

Vital Capacity

Just under 4 liters.

Residual Volume:

• A small amount of air that always stays behind in the lungs, this is so they do not collapse.
  
• How much is this person's Residual Volume?

Residual Volume

Just over 2 liters.

Total Lung Capacity:

• The maximum amount of air a person's lungs can hold.
• How much is this person's Total Lung Capacity?

Total Lung Capacity

6 liters

Tidal Volume:

• The amount of air a person moves into and out of the lungs when relaxed.
• How much is this person's Tidal Volume?

Tidal Volume

about 0.8 liters
