Term
Calc: VC (vital capacity)
Given:
TV=500 ml
ERV=300 ml
IRV= 1900 ml
Are these values normal?
or restrictive/obstructive diseases pattern? |
|
Definition
TV:yes
ERV: low,
=less air being expelled
IRV= yes
VC= TV+ ERV+IRV
500 +300 +1900= 2700
which is a low VC
b/c ERV is low=less air expelled=
lungs lost elasity=restrictive disease |
