Lung volumes Flashcards
What piece of equipment do we use to measure lung volumes
Spirometer
What is tidal volume
The volume of air that is breathed in and out during a normal breath
What is expiratory reserve volume
The volume of air that can be forcibly exhaled after a normal breath
What is inspiratory reserve volume
The volume of air that can forcibly inhaled after a normal breath
What is residual volume and what is its purpose
The volume of air that is left in the lungs after a maximal expiration
Prevents the lungs from collapsing
How do we calculate vital capacity
EV+IRV+RV
What is minute ventilation
The volume of air that leaves and enters the lungs per minute
How do we work minute ventilation
tidal volume x breathing rate/frequency
