The guy above is right. To get that high of a pa02 you would have to be on alot of supplemental 02 . A nonrebreather mask could do that....or are they intubated? The nurse is WAY wrong.

all three previous answers are wrong, including the nurse.
the human pao2 at sea level breathing room air is no more than 110mmhg under the best conditions. most typically it is about 96 to 100 mmhg (that's a pressure measurement)or about 97% saturated. room air (earths atmosphere) of course contains no more than 21% oxygen (actually 20.93%), it all works out mathematically and scientifically.
now how does one get a pao2 of 357mmhg?, breath oxygen at about 40 to 60%. so the answer to your question is that the patient is breathing supplemental oxygen. i wont go into the physics and physiology of it all but trust me that is the only way, uh except of course if the patient is placed in a hyperbaric chamber (say at 2 to 3 atmospheres) in which case the pa02 can be increased using less than 30% oxygen, again the physics nothwithstanding it has all been tested over the last 50 years.

Lots of reasons. Medical history details?
details: ok the guy below me is right but the medical condition in which it applies to can be lots of things the patient could be in a coma or on oxygen from emphysema... and it is spelled RESPIRATORY

copd, or pulmonary embolus, either can do that.
