1: review respiratory pathophysiology Flashcards
information learned prior in order to expand on advanced topics with different comorbidities
residual volume (RV)
volume of the air remaining in the lungs after maximum expiration
expiratory reserve volume (ERV)
maximum volume of air expired from the resting end-expiratory level
tidal volume (Vt)
volume of air inspired/expired with each breath during quiet breathing
inspiratory reserve volume (IRV)
maximum volume of air inspired from the resting end-inspiratory level
inspiratory capacity (IC)
IRV + Vt
maximum volume of air inspired from the end-expiratory level
vital capacity (VC)
IRV + Vt + ERV
maximum volume of air expired from the maximum inspiratory level
functional residual capacity (FRC)
(ERV + RV)
volume of air remaining in the lungs at the end-expiratory level
total lung capacity
IRV + Vt + ERV + RV
volume of air in the lungs after maximum inspiration
name the core muscles of inspiration
external intercostals
diaphragm
external intercostals
1/2 core muscles of inspiration
contract to elevate the ribs
diaphragm (inspiration)
1/2 core muscles of inspiration
contracts to expand thoracic cavity
name the accessory muscles of inspiration
scalene
sternocleidomastoid
pectoralis minor
scalene
helps to elevate clavicle and sternum
sternocleidomastoid
contracts to elevate sternum
pectoralis minor
contracts to pull ribs outwards
