10 - 15 mm Hg.
Arterial values should be between 85 and 100 mmHg, Venous values should be between 30 and 40 mmHg.
The normal partial pressure of oxygen in arterial blood is 75-100 millimeters of mercury. In comparison the partial pressure of oxygen at sea level is 750 millimeters of mercury.
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.
There are many measures of Arterial Blood Gases. The most common measure oxygen (by PaO2) and carbon dioxide (by PaCO2) levels. Normal PaO2 is 80-100 mmHg. Normal PaCO2 is 35-45 mmHg. Bicarbonate is sometimes measured and its value is 22-26 mmHg. Other measurements are also taken depending on the situation. Source: http://en.wikipedia.org/wiki/Arterial_blood_gas

PaO2 is the partial pressure of oxygen in arterial blood. Pa is the abbreviation of partial.
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.
The normal values for Areterial blood gas (for adults!) are as follows;Pao2 >> 12-15kPa (90-110mmHg)Paco2 >> 4.5-6.1kPa (34-46mmHg)Bicarbonate >> 21-27.5mmol/lH+ ions >> 36-44mmol/l (7.35-7.45 pH units)I also referred to the Baillière's Nurses Dictionary to check!
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...... Then PaO2 would be low........ Then low SaO2.....then low content CaO2..... Then low DO2.... Then Hypoxia.....lactic acidosis( anaerobic glycolysis), isn't it?
