WebNov 2, 2016 · An ABG had been performed, revealing a PaO2 of 54 mm. The medicine team was alarmed by this low PaO2, so they titrated up her oxygen while monitoring serial … WebOct 29, 2024 · The PAO 2 calculation is an estimated value using the following equation: PAO2 = FiO2 (PB-PH2O) – PaCO 2 /RQ FiO 2 = concentration of oxygen the patient is breathing PB = barometric pressure (usually kept at 760 mmHg) PH 2 O = partial pressure of water vapor (assumed to be 47 mmHg)

Web6-step approach: Step 1: Assess the internal consistency of the values using the Henderseon-Hasselbach equation: [H+] = 24 (PaCO2) [HCO 3 -] If the pH and the [H+] are inconsistent, the ABG is probably not valid. Step 2: Is there alkalemia or acidemia present? pH < 7.35 acidemia pH > 7.45 alkalemia This is usually the primary disorder WebAn arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) ...
