Question 3

Fick equation what is CO

Answer 3

VO2 = CO (CaO2-Cavo2)  CO = HR xSV 
VO2= HRxSVx(Ca02-CaVo2)

Question 4

Diffrences in Child vs, Adult in HR, SV, CO, AV difference, BP, HGB concentration, RR, Tidal volume, vital capacity, Blood Lactate levels tell whats higher and lower

Answer 4

HR- higher

SV- lower (not as much needs to be pumped to body cause its smaller)

CO- lower

AV difference - similair

Blood flow to active muscle - higher

BP- lower

RR- higher

Blood Lactate- M >F after puberty

Tidal Volume- Lower

Ventiliation - higher ( pure clean lungs )
