In alveolar air its 569.0 mm Hg. In expired air its 566.0 mm Hg. This is per Guyton & Hall's Textbook of Medical Physiology (1996)

What is the partial pressure of CO2 in the arterial and venous blood?

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.


What is the partial pressure of oxygen in blood gas a mixture of N2 O2 and CO2 if the partial pr. of Nitrogen 630 mm of Hg and partial pressure of CO2 is 39 mm of Hg?

To find the partial pressure of oxygen, we need to subtract the partial pressures of nitrogen and CO2 from the total pressure of the mixture, which is typically around 760 mmHg at sea level. Therefore, the partial pressure of oxygen would be 760 - 630 - 39 = 91 mmHg.


At sea level what is the normal partial pressure of oxygen in the systemic veins?

The normal partial pressure of oxygen in the systemic veins at sea level is around 40 mmHg. This value indicates the pressure exerted by oxygen molecules in the blood and corresponds to the oxygen content in the venous blood returning to the heart.


What is co2 blood level?

CO2 in the blood stream can be measured from bicarbonate in the blood or pCO2 (partial pressure). Normal CO2 measured from bicarbonate is 22-28 mEq/L Normal pCO2 is 35-45 mmHg

If nitrogen were pumped into your lungs at high pressure what would happen to its solubility in your blood?

If nitrogen were pumped into your lungs at high pressure, its solubility in your blood would increase due to Henry's Law, which states that the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid. This could lead to nitrogen bubbles forming in the bloodstream, causing decompression sickness or "the bends."


What is the normal partial pressure of carbon dioxide in pulmonary arteries?

That depends on whether you are asking about the red blood cells themselves, or the blood as a whole. The fluid portion of the blood will have a O2 partial pressure around 20%, but the red blood cells will have an O2 partial pressure nearing 100%.

What numbers represent normal blood pressure?

Normal blood pressure is measured by two numbers that represent how much mercury is in your blood. A completely normal blood pressure reads: Below 120 / below 80.


What is the normal pressure of blood?

Normal blood pressure in an adult would be 120/80


Why is the partial pressure of oxygen in tissue lower than the partial pressure of oxygen in the blood?

The partial pressure of oxygen in tissue is lower due to oxygen being delivered from the blood to the tissues for cellular respiration. As tissues consume oxygen for metabolic processes, the partial pressure decreases. Additionally, factors like distance from capillaries and tissue oxygen consumption rate impact the partial pressure of oxygen in tissues.
