Lab 10 Pulmonary Physiology Flashcards
Dead air space
Air that cannot be completely inhaled into the lungs and the air that cannot be fully exhaled from our body
Residual volume
The volume of a remaining in the lungs after a Maximal exhalation
1.2 L
Alveoli
Small pouches of the lungs with capillaries
Respiration Rate
The number of breaths each minute when breathing normally
T2-T1
Tidal volume
Is the average amount of air you breathe in and out when breathing normally
V2-V1
Alveolar tidal volume
The average amount of air reaching her lungs when breathing normally
Average tidal volume - dead air space
Minute alveolar ventilation rate
The amount of air reaching your lungs each minute when breathing normally
Alveolar tidal volume• respiration rate
Vital capacity
The maximum amount of air you can breathe in and out when taking a larger breath
V2-V1
Total lung capacity
The total amount of air in your lungs can hold
Residual volume + vital capacity
Forced vital capacity
The maximum amount of air you can forcefully breathe in and out when taking a large breath
Forced expiratory volume at 1 second
This is the maximum out of air you can forcefully exhale in one second
Percent expiratory flow
The ratio of FEV1/FVC
