Breathing Rate Flashcards
What is a spirometer?
A machine that can be used to investigate breathing rate, vital capacity, tidal volume and oxygen uptake
What is vital capacity?
The maximum volume of air that can be breathed in or out in one breath
What is residual volume?
The remaining volume of air in the lungs
What is tidal volume?
The volume of air breathed in or out at rest
What is oxygen uptake?
The amount of oxygen consumed by the subject (dm3/min)
How can the oxygen uptake be increased?
Increased breathing rate or deeper breaths
What precautions should you take when using a spirometer?
•Wear loose, comfortable clothing that doesn’t squeeze your chest.
•Refrain from eating a large meal at least two hours before the test.
•Avoid any heavy exercise at least 30 minutes before the test.
What removes the carbon dioxide from the spirometer tube?
Self-indicating soda-lime granules
How do you calculate the maximum value for tidal volume?
Max tidal vol - min tidal vol
What is the thorax?
The medical term for the chest
