Repiratory Flashcards
What is the importance of measuring the volumes and the capacities of an individual
It’s useful in assessing an individuals respiratory
What is a spirometer?
Used to determine the volumes of air that moves in and out of the lungs during the various phases of respiration
Define tidal volume
The amount of air that moves in or out of the lungs during normal respiratory
What’s the normal tidal volume?
Male: 500ml
Female: 500ml
Define ERV
The amount of air that can exhale beyond tidal volume
What the normal ERV
Male: 1200 ml
Female: 700 ml
Define VC
The largest amount of air an individual can move in or out of the lungs in one respiratory cycle
What are the normal VC values?
Males: 4800 ml
Females: 3100 ml
Define IRV
The amount of air that can be forcibly inhaled beyond tidal volume
What is the normal IRV
Males: 3100 ml
Females: 1900 ml
What cannot be directly measured when it comes to respiratory
Inspiratory reserve volume (IRV)
What is the formula to calculate IRV
VC=TV+ERV+IRV
When a person inhales normally and exhales normally and then exhales further to give what?
ERV
When a person inhales normally and exhales as much ad possible that gives?
ERV
A person inhales as much as possible and exhales as much as possible to give?
VC
