Analysis of respiratory status There was a small, gradual increase in CBF when PaO2 was lowered in steps from 130 to 55 mm Hg, and a more pronounced increase at PO2 values below 50 mm Hg. At PaO2 25 mm Hg CBF increased to values of 500% of normal. According to the oxy-hemoglobin saturation curve, the arterial pO2 should be ~40 mm Hg when the hemoglobin saturation is 75% (figure 1). However when you … constant tissue PO2 Alveolar PO2 between 60 – 500 mmHg still tissue PO2 does not vary more than few mmHg from the normal(40mmHg) 2010-10-26 The pre-membrane gas is analogous to a mixed venous oxygen saturation, and the PO2 is typically 40-60 mmHg. The PaO2 of post-membrane gas should be very high, in the range of 350-500 mmHg, anything lower should raise suspicion that the oxygenator is malfunctioning and needs to be replaced. 2015-10-11 A look at the oxyhemoglobin dissociation curve helps explain why the (A-a)PO2 difference is so high.

For example, a patient on room air is breathing 21% oxygen and so the PaO2 should be ~ 105 mmHg. A patient on 100% oxygen should have a PaO2 of ~500 mmHg. A patient on 40% FIO2 should have a PaO2 of ~200 mmHg. P a O 2 – Partial pressure of oxygen at sea level (160 mmHg in the atmosphere, 21% of standard atmospheric pressure of 760 mmHg) in arterial blood is between 75 mmHg and 100 mmHg.

what happens to the PO2 as that air enters the trac A patient's PaO2 (at sea level) should be 5 x the inspired oxygen percentage (FIO2). For example, a patient on room air is breathing 21% oxygen and so the PaO2 should be ~ 105 mmHg. A patient on 100% oxygen should have a PaO2 of ~500 mmHg. A patient on 40% FIO2 should have a PaO2 of ~200 mmHg. P a O 2 – Partial pressure of oxygen at sea level (160 mmHg in the atmosphere, 21% of standard atmospheric pressure of 760 mmHg) in arterial blood is between 75 mmHg and 100 mmHg.

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 For example, increasing the arterial pO2 from 80 to 500 mmHg floods the arterial-end tissues with oxygen and increases the axial gradient . This increased axial gradient then results in axial vectors that can extend into the lethal corner area, helping to suppress the formation of an anoxic lethal corner until adequate blood flow can be restored. This is the genesis of the oxygen window.

Change of atmospheric o2 concentration markedly the buffer effect of HB still maintain almost constant tissue PO2 Alveolar PO2 between 60 – 500 mmHg still tissue PO2 does not vary more than few mmHg from the normal(40mmHg) Last modified by: A pO2 <60 mm Hg or SpO2 (pulse oximetry) <91% breath-ing room air pCO2 >50 mm Hg and pH <7.35 (hypercapnic) P/F ratio (pO2 / FIO2) <300 pO2 decrease or pCO2 increase by 10 mm Hg from base-line (if known). 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.

Breathing air under normal conditions at 1 ATA, the average arterial-venous (a-v) difference in PO2 is about 50 mmHg, meaning that venous PO2 (PvO2) is about 50 mmHg less than PaO2. As PO2 is reduced 50 mmHg, PCO2 increases only 5 mmHg from the arterial to venous blood. - 2 75 mmHg (PaO) 7.2 mmHg (A-a PO2 gradient) VD physiologic VDphysiologic = PaCO2 - PECO2 PaCO2 x VE VD VT = PaCO2 - PECO2 PaCO2 VDphysiologic = 40 - 27 40 x 500 VD FiO2 can also affect an ABG reading. The PaO2 on your ABG should equal FiO2 x 500. If it doesn’t, there’s probably an A-a gradient. The PaO2/FiO2 ratio (or P/F ratio) is useful for categorizing hypoxia as potentially severe (when applied to ARDS). So what about the patient above?
