basic science of sedation Flashcards
1
Q
tidal volume
A
amount of air moving in or out of lungs with each respiratory cycle
usually 400-500ml
2
Q
residual volume
A
volume left in lung even after maximum expiration
3
Q
FEV1
A
forced expiration volume in 1 second
4
Q
what do restrivtive pulmonary diseases make it harder to do
A
inhale
normal rates of respiration but at smaller volumes
5
Q
what do obstructive pulmonary diseases make it difficult to do
A
exhale
6
Q
conducting zone of airways
A
anatomical dead space, no gas exchange taking place
compromised of trachea, bronchi and terminal bronchioles
7
Q
respiratory zone of airways
A
region of gas exchange
compromised of respiratory bronchiole, alveolar duct and alveolar sac
8
Q
ventilation
A
flow of air in and out of alveoli from atmosphere
9

A
flow of blood to alveolar capillaries
