Perhaps the short answer was already given on tidal volume and I missed it:
The average male adult (whatever one of those looks like), at rest, when awake: 500 mL
The average female adult, at rest, awake: 25% less than that.
Naturally, size does matter (height, width, weight, anatomy) as well as general health, age, condition, and all that stuff. And sleep confuses the issue, I think.
Yeah, I know, the above is merely a layman's ballpark middle-of-the-road figure, so it may be next to useless in the grand scheme of things. But I am a layman, and here in NYC, our layman's ballparks ARE the middle of the road whenever a game of stickball breaks out using the nearest cars' hubcaps for bases.

What is a normal tidal volume and Peak flow
Re: What is a normal tidal volume and Peak flow
normal tidal volumes have nothing to do with weight.... if you get fatter, do your lungs get bigger too???? I don't think so.... the normal tidal volumes can be based on IBW but not the patients current weight.... that figure, 10-15 ml/kg is pretty old calculation, the new calculation is based on "less is more".... 4-6ml/kg is ideally a better fit..Strapparatus wrote:Normal tidal volume for individuals is based on weight in kg (10-15 ml/kg).
peak flow is based on age and height and gender. Peak flows decrease incrementally with age, height and gender.
google: nomogram for peak flows and seek out a chart to determine your normal.

Still, watch out, your feeling may sometimes fool you.Slinky wrote:Hey, Guest, "ain't" nuttin' in this world 100% guaranteed in this life but death and taxes and I'm beginning to wonder 'bout death, but have plenty of faith in the taxes. These xPAPs give us some info to work with, we don't necessarily take it as gospel. H*ll, an xray, CT scan or MRI result is only as good as the radiologist reading it. In the end, I always believe how I FEEL more than I do any of those test results.

Re: What is a normal tidal volume and Peak flow
tv is the volume of air inhaled or exhaled in one respiratory cycle.. its 10-15 ml per kg so for a healthy adult it will be 500ml

PLEASE stop posting that value and go back and reread the rest of this thread.Guest wrote:tv is the volume of air inhaled or exhaled in one respiratory cycle.. its 10-15 ml per kg so for a healthy adult it will be 500ml
Normal resting tidal volume in a spontaneouly breathing adult is 5 - 7 ml/kg.
