75 mm Hg to kPa = 9.99918 kPa. 100 mm Hg to kPa = 13.33224 kPa ›› Under optimal conditions during O2 breathing at 1 ATA, PaO2 would be about 500 mmHg. Because of the greater difference between alveolar and arterial PO2, arterial blood is undersaturated by 166 mmHg. As blood moves through tissue, the same 4.5 mL O2/dL blood is extracted, and PO2 falls to 57 mmHg in venous blood. pO2: Partial pressure of oxygen, or oxygen content, in mmHg: pO2 > 80 mmHg: pCO2: Partial pressure of carbon dioxide, or carbon dioxide content, in mmHg: 35 – 45 mmHg: pH: Measure of the degree of acidity: 7.35 – 7.45: SaO2: Oxygen saturation (percent of hemoglobin carrying oxygen) as reported on ABG and is relatively proportional with pO2 > 95%: SpO2 2010-04-28 · Normal PaO2 values = 80-100 mmHg; Estimated normal PaO2 = 100 mmHg – (0.3) age in years; Hypoxemia is PaO2 < 50 mmHg; PaO2/FiO2. The PaO2 rises with increasing FiO2. Inadequate or decreased oxygen exchange decreases the ratio.

30 mm Hg to kPa = 3.99967 kPa. 40 mm Hg to kPa = 5.3329 kPa.

pO2-värdena minskar med (2 mmHg + 6 %) per 100 mmHg barometertryck under N-acetylcystein har ingen signifikant effekt upp till 500 µM (8,2 mg/dl).

2021-03-17 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. [4] [5] [6] Venous blood oxygen tension (normal) A patient's PaO2 (at sea level) should be 5 x the inspired oxygen percentage (FIO2).

Venous PO2= 60 mmHg. arterial, tissue, venous PO2 at muscle with normal blood flow and increased metabolism. Arterial PO2= 100 mmHg Muscle PO2= 20 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. at PO2 < 333 mm Hg, O2 dissolved can be ignored Online calculator to convert atmospheres to millimeters of mercury (atm to mmHg) with formulas, examples, and tables.

Det transpulmonella trycket blir då +4mmHg eftersom 0 - (-4) = 4 mmHg Man inandas ca 500 mL men endast 350 mL deltar i gasutbytet. När pO2 sjunker till <80mmHg (vi har oftast runt 100mmHg) börjar det bli känsligt, då skickar  (mikrogram/ml). Infusionshastighet.
