4 major steps of EXTERNAL RESPIRATION.
which are function of pulmonary system? which are of CV system?
ventilation - gas move from air to alveoli
Diffusion - gas move from alveoli to blood
perfusion - gas move thru lung
Transport - lung to tissue (only one that is of CV system)
Total cross sectional area in cm2 of
trachea
bronchioles
alv ducts
2
150
6000
which part of the resp pathway has the highest flow velocity?
upper airway
What is TV? normal volume?
Tidal volume - volume inspired w/ NORMAL BREATH
500 mL
IRV? nornmal value?
Inspiratory reserve volume (inspiration w/ full force) 3100 mL
ERV? normal value?
Expiratory reserve volume - max beyond normal expiratory TV - 1200 mL
RV? normal value?
residula volume - left after forceful expiration. 1200 mL
TLC? value?
total lung capacity 6000 mL
whta 2 values does TLC relate to mathematically?
VC+RV
IC? normal value?
inspiratory capcity - total volume that can be pulled in 3600 mL
What 2 values does Inspiratory Capacity relate to?
TV+IRV
choices:
obstructive/restrictive, alveo-capillary block, VQ mismatch/hypoxemia, ischemia/anemia
a - obstructive/restrictive
b - alv-cap block
c - V-Q/hypoxemia
d -ischemia/anemia
FRC? normal value?
Functional residual capacity - total in lungs after a normal, tidal expiration - 2400 mL
what 2 values does FRC relate to?
ERV + RV
VC? normal value?
Vital capacity - maximum a person can expel after lungs completely filled - 4600 mL
what 2 values does VC relate to?
IC + ERV
What is Respiratory minute volume (RMV) equal to?
Vt x resp rate
What is Va? how does it relate to RMV?
it is the value of what actually goes into lungs
= (Vt -ADS) x Resp Rate
