Best Answer

A decrease in PO2 can occur due to factors such as high-altitude exposure, lung diseases like COPD or pneumonia, breathing difficulties, or oxygen deficiency in the air. Inadequate ventilation, poor oxygen exchange in the lungs, or reduced oxygen-carrying capacity of the blood can also lead to decreased levels of PO2.

PO2 in blood is the amount of gases in your blood. In medical terms, this is commonly called the Alveolar-arterial.


The relative PO2 and PCO2 in pulmonary arteries and veins and systemic arteries and veins?

In pulmonary arteries, PO2 is around 40 mmHg and PCO2 is around 46 mmHg. In pulmonary veins, PO2 is around 100 mmHg and PCO2 is around 40 mmHg. In systemic arteries, PO2 is around 100 mmHg and PCO2 is around 40 mmHg. In systemic veins, PO2 is around 40 mmHg and PCO2 is around 46 mmHg.

What would be the pH of a solution when H3PO4 equals H2PO4?

When H3PO4 equals H2PO4-, the solution is a buffer system. The pH of the solution would be around the pKa of the H3PO4/H2PO4- buffer system, which is around 7.2-7.4 for the first dissociation of phosphoric acid.


What would be the value of PO2 in the humidified air?

The partial pressure of oxygen (PO2) in humidified air would depend on the concentration of oxygen in the air and the vapor pressure of water at the given temperature. As humidity increases, the partial pressure of oxygen may decrease slightly due to the presence of water vapor. An oxygen partial pressure of around 21% is typical in dry air at sea level.
