Question

1. CPT = 6000 cm³
CV = 4500 cm³
VC = 500 cm³
VIR = VER

VR? DIR? D.R.? - 18 resp./min.


2. VC = 500 ml
VIR = 2500 ML
VR = 1500 ml
CV = 50% D.R.

D.R.? F.R. = 20 respiratii/min.
VER? CPT?


3. CV = 5000 ml
VC= 500 ml
VIR = 2500 ml
VR = 50% VER

VR? CPT?


4. VC = 600 ml
VER = 2200 ml
VER = VIR
VR = 3VC

CV? CPT? D.R.? FR = 20 respiratii/min.

Answer 1

1) CPT= CV + VR
6000= 4500 + VR
VR = 600-4500 = 1500 ml

DR= VC x FR
DR= 500 x 18 = 9000ml => 9 l

2) DR= VC x FR
DR= 500 x 20 = 10.000ml => 10 l

CV= 50/100 x 10.000 = 5000ml
CV= VIR+VER+VC
5000=2500+VER+500
5000=3000+VER
VER=5000-3000=2000ml

CPT=CV+VR
CPT= 5000+1500= 6500ml

3) CV=VIR+VER+VC
5000=2500+VER+500
VER=2000ml
VR=50/100 x 2000= 1000ml

CPT=CV+VR
CPT=5000+1000= 6000ml

4) VR=3x600=1800ml

CV=VIR+VER+VC
CV=2000+2000+600
CV=4600ml

CPT=CV+VR
CPT=4600+1800=6400ml

DR=VCxFR
DR=600x20
DR=12.000ml => 12 l
