Respiratory System #3 Flashcards
1
Q
Spirometry
A
measures respiratory volumes
2
Q
Total lung volume
A
total lung capacity varies on
1. Height
2. Age (age increases, TLC decreases due to the loss of elasticity)
3
Q
Tidal volume
A
amount of air inhaled or exhaled when resting
- 500 mL
4
Q
Inspiratory Reserve Volume
A
amount of air that you can forcefully inhale after a tidal inhalation
5
Q
Expiratory Reserve Volume
A
amount of air you can forcefully exhale a tidal exhalation
6
Q
Vital Capacity
A
max amount of exhalation after a maximal inhalation
7
Q
FEV 1.0
- Force Expiratory Volume
- 1.0 seconds
A
how much you can exhale in 1 second
- 80% of vital capacity
- ex: 4L of vital capacity = about 3.2 FEV 1.0
- less than 80% can be due to Obstructive Pulmonary Disease; Chronic Bronchitis
