P/F RATIO The P/F ratio equals the arterial pO2 divided by the FIO2 (the fraction of inspired oxygen expressed as a decimal) the patient Thus, a 40-year-old should have an A–a gradient around 12.5 mmHg. The value calculated for a patient's A-a gradient can assess if their hypoxia is due to the dysfunction of the alveolar-capillary unit, for which it will elevate, or due to another reason, in which the A-a gradient will be at or lower than the calculated value using the above equation. normal < 15 mmHg AlveolargasAlveolargas-Gleichung PAO 2 = PIO 2– (PaCO 2/RQ) PIO 2 = FiO 2 (PB - pH 2O) RQ = CO2-Abgabe/O2 Aufnahme = 0.85 PAO 2 = 0,21x(760-47)-(40/0,85)= 103 mmHg Hypoxämie – respiratorische Ursachen Ursache P(A-a)O 2 Pulmonaler rechts-links Shunt V/Q-Störung Diffusionsstörung Hypoventilation normal Niedriges FiO 2 normal (mm Hg) [0.0225 X PO2 (kPa)] i.e., directly proportional to the partial pressure of O 2 – at typical PO2’s, it is negligible: 0.003 x 100 mm Hg = 0.3 mL/dL 0.0225 x 13.3 kPa = 0.3 mL/dL (vs Hgb-bound O 2 of 19.6 ml/dL, which we just calculated) P50 is the PO2 corresponding to 50% saturation of Hb (half-saturation point = 27 mm Hg) CaO2 - CvO2 represents the total amount of O2 extracted (mL O2/dLblood) body wide. total O2 content in the blood computes as the sum of O2 bound to hemoglobin (HbO2) and O2 dissolved.

As one descends below sea level, as in ocean diving, the total pressure increases by one atmosphere for every 33 feet. At 33 feet therefore, the pressure equals 2 x 760 = 1,520 mmHg.

Thus, a 40-year-old should have an A–a gradient around 12.5 mmHg. The value calculated for a patient's A-a gradient can assess if their hypoxia is due to the dysfunction of the alveolar-capillary unit, for which it will elevate, or due to another reason, in which the A-a gradient will be at or lower than the calculated value using the above equation.

PO2 (Partial Pressure of Oxygen) reflects the amount of oxygen gas dissolved in the blood. It primarily measures the effectiveness of the lungs in pulling oxygen into the blood stream from the atmosphere. Elevated pO2 levels are associated with: Increased oxygen levels in the inhaled air; Polycythemia
