Refining Extracorporeal Support Strategy: Oxygen Pressure Field Theory IX

OPFT Part IX:   Using OPFT to Refine Extracorporeal Support Strategy. The anion gap is the difference in the measured cations and the measured anions in serum, plasma, or urine. The magnitude of this difference (i.e. “gap”) in the serum is often calculated in medicine when attempting to identify the cause of metabolic acidosis. If the […]
