In other studies we have observed only a slight effect of cell volume on furosemide-sensitive K+ influx in whole blood, but much larger effects in cells which had been washed

If the original blood sample was not pre-equilibrated prior to tonometry, the intersection point for true plasma buffer lines of different Ht corresponded closely to the expected
