View Full Version : flow rate vs minute ventilation?

05-04-2010, 02:16 AM
hello.. i know that it might be a foolish thing to ask this, but in my place, we are not talking much about this, so my understanding about this basic thing is very little,,

i am learning about oxygen therapy and i realize that it involves talking about inspiratory peak flow rate and minute ventilation...now, my question is :
1. what is the difference between them?
2. why should we consider peak inspiratory flow rate in oxygen therapy?
3. what relationship does the peak inspiratory flow and minute ventilation have? i mean, how can they affect each other?

please help...thx u

do you mean flow vs ventilation ? ?? if so maybe i can help

if you are , what u have to take in to consideration is gravity .
b/c of gravity it will pull the blood down so flow will increase at base of lung vs apex , but ventilation will be better at apex than base, key word BETTER NOT MORE there for there will be more oxygen at apex
