What's the difference between Oxygen Tension And Partial Pressure

Homework Equations


.....uh....rules of grammar ?

The Attempt at a Solution


If I knew the solution I wouldn't be here now would I ?
Links?

Pardon me ?
You're pardoned. What do you find when you type those terms into Google? I think most of us are familiar with the term Partial Pressure, but I've never heard of Oxygen Tension (but I'm not a chemist). To save a few dozen people all having to use Google to try to contribute to the thread, it would be good if you could do that Google search yourself to save us all of that cumulative time.

Heck, you might even be able to answer your own question with the results of that search. Let us know what you find. Thanks. :smile:

Basically they are saying that
oxygen tension is partial pressure of oxygen
Which is funny because today in class sir disagreed with that statemwnt somewhat and asked us to go deeper.

oxygen tension is partial pressure of oxygen
Actually they are being more specific than that. What is more specific about oxygen tension than the more general definition of partial pressure? :smile:

Good news !!!
We discused the problem with our Awesome proffesor.

So here it goes
Basically Oxygen tension is specific to oxygen disolved in blood plasma while partial pressure is the indepent pressure exerted by a gaseous components of a multi gaseous mixture

Secandly partial pressure refers to gases while oxygen tension is of DISSOLVED blood plasma oxygen.

Yep, that's what I saw in the links you posted. Now we all learned something new! :smile:

For me that's hair splitting, if you express concentrations as mmHg you are referring to the equilibrium partial pressure of the gas. Dissolved gas doesn't exert any pressure that you could measure.

Sadly, this is nothing unusual, in many sciences people use simplified ways of expressing values and are ready to "explain" what they "really" mean, while what they use is actually only some proxy (sometimes even a misunderstood one).

Precisely !
