    "description": "A test of how well oxygen crosses from the air sacs into the bloodstream. The patient takes in a single deep breath containing a trace of carbon monoxide, holds it for about ten seconds, then blows out; the amount of that gas absorbed shows how effectively the lung membrane and the blood supply behind it are working. It is done alongside other pulmonary function testing in the same sitting rather than on its own, so it is recorded in addition to the main breathing study.",
