Oxygen Extraction Ratio (O2ER)

Oxygen Extraction Ratio (O2ER)

Oxygen Extraction Ratio (O2ER) is the amount of oxygen extracted by the peripheral tissues (CaO2-CvO2) divided by the amount of oxygen delivered (CaO2) to the peripheral tissues. Normal O2ER is around 0.25 or 25% O2ER: Oxygen Extraction Ratio CaO2: Arterial oxygen...
