Long neck, but narrow; massive lungs, 8x the size of a human's; a strong heart that gives it blood pressure twice that of a human's; and a respiration rate 1/3 as slow as a human's.

Essentially: their throat will fill with dead air; it's too big not to. But, their lungs are huge, and they have a respiration rate 1/3 the speed of a human's, sucking as much oxygen out of their air as possible. Their cavernous lungs and ability to sip oxygen out of them, plus their hard-beating heart's ability to efficiently spread that O2 all over their bodies, mitigates the threat of dead air build-up in their throat.
