Arterial Blood Gases and Dialysis

I was wondering if anyone knew exactly how long after a patient has had dialysis, would drawing a blood gases be sufficient. I figure since Dialysis filters the blood, that it could possibly change the pH, Pao2, PaCo2, but how significantly? One Pulmonoligist said 2 hrs, and the other said it would not matter. Has anyone ran across info in this subject, or studies ?

personnaly I have found an hour after dialysis ABG'S project a great clinical picture if not a precise or accurate clinical picture but a look into a trend hopefully going to an optimal clinical picture. I would place it in the same category as after bicarb entering the system a good 1 hour time fromm administration to analysis
