What is the normal value of PaO2?
Arterial values should be between 85 and 100 mmHg, Venous values should be between 30 and 40 mmHg.
In a normal adult what is the approximate value of PAo2?
Hi 10-13 kPa is the normal range, but that is a bit of an over simplification.

How do you calculate SO2?
(H2PO2)- is the chemical formula of the hypophosphite anion.
Blood gases?
DefinitionBlood gases is a measurement of how much oxygen and carbon dioxide is in your blood. It also determines the acidity (pH) of your blood.Alternative NamesArterial blood gas analysis; ABGHow the test is performedUsually, blood is taken from an artery. The blood may be collected from the radial artery in the wrist, the femoral artery in the groin, or the brachial artery in the arm.The health care provider may test circulation to the hand before taking a sample of blood from the wrist area.The health care provider will insert a small needle through the skin into the artery. You can choose to have numbing medicine (anesthesia) applied to the site before the test begins.In rare cases, blood from a vein may be used.After the blood is taken, pressure is applied to the site for a few minutes to stop the bleeding. The health care provider will watch the site for signs of bleeding or circulation problems.The sample must be quickly sent to a laboratory for analysis to ensure accurate results.How to prepare for the testThere is no special preparation. If you are on oxygen therapy, the oxygen concentration must remain constant for 20 minutes before the test.How the test will feelYou may feel brief cramping or throbbing at the puncture site.Why the test is performedThe test is used to evaluate respiratory diseases and conditions that affect the lungs. It helps determine the effectiveness of oxygen therapy. The test also provides information about the body's acid/base balance, which can reveal important clues about lung and kidney function and the body's general metabolic state.See also:AcidosisDiabetic ketoacidosisLactic acidosisMetabolic acidosisRespiratory acidosisRespiratory alkalosisNormal ValuesValues at sea level:Partial pressure of oxygen (PaO2) - 75 - 100 mmHgPartial pressure of carbon dioxide (PaCO2) - 35 - 45 mmHgA pH of 7.35 - 7.45Oxygen saturation (SaO2) - 94 - 100%Bicarbonate - (HCO3) - 22 - 26 mEq/LNote: mEq/L = milliequivalents per liter; mmHg = millimeters of mercuryAt altitudes of 3,000 feet and above, the oxygen values are lower.Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What abnormal results meanAbnormal results may be due to lung, kidney, or metabolic diseases. Head or neck injuries or other injuries that affect breathing can also lead to abnormal results.What the risks areThere is very little risk when the procedure is done correctly. Veins and arteries vary in size from one patient to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.Other risks associated with this test may include:Bleeding at the puncture siteBlood flow problems at puncture site (rare)Bruising at the puncture siteDelayed bleeding at the puncture siteFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)Special considerationsTell your health care provider if you notice bleeding, bruising, numbness, tingling, or discoloration at the puncture site. Also let your doctor know if you are taking any blood-thinning medications (anticoagulants) or aspirin.ReferencesGold WG. Pulmonary function testing.

What is the formula for AA gradient?
PAO2 - PaO2 ****************************************** PAO2 is the Alveolar Air Equation: PAO2 = FiO2 (Pb- Ph20) - PACO2/R Notes: Pb = 760 mmHg Ph20 = 47 mmHg R = 0.8
If PAO2 is low and bicarb is low what is the problem?
If PAO2 is low...... Then PaO2 would be low........ Then low SaO2.....then low content CaO2..... Then low DO2.... Then Hypoxia.....lactic acidosis( anaerobic glycolysis), isn't it?
What is the normal range of PAO2 - PaO2 for healthy young adults breathing room air?
10 - 15 mm Hg.
What is importance of PaO2?
A PaO2 is the level of oxygen in your arterial blood. If it is too low, it can cause significant loss in brain function. It can also cause organ failure. If the PaO2 is low, it will cause shortness of breath and also confusion.
What is the pao2 when the Oxygen Saturation 90 percent?
60
Is pao2 and po2 the same?
yes they are just the same
What are the normal ranges for PaO2 and PaCO2?
95-100
How do you increase pao2 with mechanical ventilation?
In manual ventilation you can increase the PaO2 by hyperventilating the patient, by increasing the respiratory rate and/or by increasing the volume of air that you deliver to the patient. If using a BVM for example, compressing the bag faster and/or harder will increase the arterial oxygen pressure, but there is a limit to what you can do with manual ventilation. Perfusion in the lungs has a major impact on PaO2. Also, the blood chenistry (anemia or CO2 poisoning) for example will dramatically decrease the PaO2. Sometimes no matter how much you hyperventilate the person, low PaO2 can't be corrected.
What is the highest PAO2 one could expect to observe in an individual?
140mmHg
Does oxygen react with protactinium?
Oxides of protactinium are formed: PaO, PaO2, Pa2O5.
How do you calculate PAO2?
{(Pb-47)FIO2} - (PaCO2 X 1.25) "only use the 1.25 if FIO2 is >60%"
What is the highest PaO2 one could expect to observe in an individual breathing room air at sea level?
159.6
