Spirometer:
If a person breathes , removes air from the box, the lid will drop causing the pen to drop. This is halation.

When they breathe out, the lid will and pen rises. This is halation.

Over time, the chamber air content will as the CO2 is absorbed by lime and oxygen is removed. Then O2 consumption can be calculated.

The graph line will go as oxygen decreasesin the chamber. One curved "u-shape" is one , showing inhalation and exhalation.

People with aa or COPD (chronic obstructive pulmonary disease) should not take part.

What happens to oxygen consumption as a result of excercise? Can you explain why?

Selecione uma das seguintes:

  • O2 consumption decreases as muscles respire less and require less O2.

  • O2 consumption remains the same as muscles have reserves of O2.

  • O2 comsumption increases as muscles respire more and require more O2.
