A normal blood gas should be memorized using single values rather than a range: pH 7.40, pCO2 40, pO2 100, BE 0, HCO3 24. Our patient's arterial blood gas (ABG) shows that the partial pressure of oxygen (pO2) is slightly low, but satisfactory.n arterial blood gas obtained with the patient breathing room air shows pH 7.35, pCO2 33, pO2 80, BE -7, HCO3 16, O2sat 93%. He is placed on 6 L oxygen by mask, an IV fluid infusion is begun, and antibiotics are administered.
For example, an SpO2 of 85% equals a PO2 of 60mmHg. From this it is easy to see that an oxygen saturation of 90% gives a PO2 of 70mmHg. You will also notice that at this point an increase in FiO2 will not affect PO2 in a major way compared to increasing FiO2 when a patient has an SpO2 of 85%.
