Respiratory 8 Flashcards
What is a Spirometry test?
A pulmonary function test to determine the amount and the rate of inspired and expired air
What does a Spirometer record?
The amount and the rate of air that you breathe in and out over a period of time
What cannot be measured by a spirometry test?
- Residual volume
- Functional residual capacity
- Total lung capacity
What is Atelectasis?
Complete or partial collapse of a lung or lobe of a lung that develops when alveoli become deflated or collapse
What is the Tidal volume?
The amount of air that is breathed in or out during each respiratory cycle
What is the expiratory reserve volume?
The maximum amount of air that you can expel after a normal expiration
What is the inspiratory reserve volume?
The amount of air that you can maximally inhale after a normal inspiratory effort
Why can’t a spirometry test measure the residual volume?
Because no matter how much you exhale there will always be air in the lungs
Why is the residual volume advantageous?
Because it prevents collapsing of the alveoli
What are the Capacities?
Measurements of lung volume. They correspond to the sum of two or more lung volumes
What is Vital Capacity?
The volume of air that can be possibly expelled after a maximal inspiration
What is the equation for Vital Capacity?
VC = TV + IRV + ERV
What is Inspiratory Capacity?
The maximal volume of air that can forcibly inhaled
What is the equation for Inspiratory Capacity?
IC = TV + IRV
What is Functional Reserve Capacity (FRC)?
The volume of air remaining in the lungs at the end of normal expiration
