Here’s a little Oboe Sonata. Published as “by Vivaldi” in 1737, but in fact by the French composer Nicholas Chédeville.
No Noteperformer: just Dorico playing back the notation as written.
Apart from the fact that the oboist doesn’t take a breath, 
I think it’s rather good. Some of the trills are better than others: some are a bit mechanical.
Well, I’ve read somewhere[1] that oboists breath not so much to take air in for playing, but rather to keep the accumulating carbon dioxide in their lungs from reaching critical levels, so this might not be that far from what they would at least be capable of. 
(To all oboists around here: Please do correct me if I’m wrong.)
True, but the advantage is that an oboist rarely escapes a minor stroke during his career. Here, at least, the medical risk is completely eliminated. 
In a recent piece I’ve played on oboe, I actually had to go through and mark where to breathe OUT because the composer didn’t leave enough time to both breathe OUT stale air and breathe IN new air.
It was both very tiring and very tiresome. Some composers are just idiots.
EDIT: To clarify - I had to breathe OUT enough air to not pass out, while still saving enough air to get to the next break in the line so I could breathe IN.
I had to lay out the next piece just to equalize the correct amount of Oxygen and Carbon Dioxide in my system so as to not also pass out.
I play (used to, it’s still in the cupboard) Cor Anglais (English horn). I describe it as blowing though a straw where it is blocked at the other end with hardened glue, where you managed to drill a small hole in it to pass out a little air.
The amount of air you are blowing has to be controlled (related to volume, phrasing, slurs, dynamics etc.) but it is a small amount of air going through.
You might be thinking, then just take a smaller breath in but this does not give enough push/control capacity (you are using your diaphragm for control), so this is why you have to take a reasonable breath in.
So imagine blowing out only through your straw for a while, the volume in your lungs goes down a little, but you need to take in a fresh breath. In order to do this, you need to breathe (push) out air (sometimes quickly) so you can have a good refreshing, controllable breath back in as @hautboisbaryton has mentioned.
I also play flute and there is quite a contrast in the way you have to approach breath/diaphragm for each instrument.
A trio sonata where the basson is as prominent, if not more so, than the hautbois.
[edit] After some further research, this is a Pastorale from the „Il pastor fido“ sonatas by Nicolas Chédeville. There is a reason why they were published as pieces by Vivaldi:
Chédeville made a secret agreement in 1737 with Jean-Noël Marchand to publish a collection of his own compositions as Vivaldi’s. Chédeville supplied the money and received the profits, all of which was attested to in a notarial act by Marchand in 1749. Long attributed to Vivaldi, the set of sonatas are actually the work of Chédeville.
I flirted with oboe for a little while. I was fascinated by the problem of breathing. As others have said, you have to learn to breathe out before breathing in because the likelihood of you exhausting your lung capacity before needing to breathe again is almost nil. I also found that I burped a LOT for the first 10 minutes of playing as all the pressure in your abdomen forces the air out of your stomach too. It’s all quite odd, and a far cry from singing or playing brass.
Well, I could have told you that.. 
I was just wanting to see what people thought of Dorico’s own ‘phrasing’, just with humanization and pitch contour emphasis, given all the talk of Noteperformer’s direction.
Nicely done. Here is a work of mine I posted awhile ago (created with Dorico, of course), but here I used NP 5.0.0 and your wonderful GPO5 playback engine . You have given my Garritan library new life. SO much better than NP’s strings. Except for a touch of ‘Analog Warmth’ EQ from Izotope’s Ozone 11 EQ (free with Kontakt Start) it’s just NP 5.0.0 and your GPO5 engine. Thank you! 
Oops, sorry for hijacking your thread by shifting the focus to physical air compound and pressure management.
