As a subject matter expert in the field of respiratory physiology, I can explain the differences between hypoxia and hypoxemia. Hypoxemia is a specific medical condition where the arterial oxygen tension or partial pressure of oxygen (PaO2) in the blood is below normal levels, which is typically considered to be between 80 and 100 mmHg. This is a quantifiable measurement that can be directly assessed through laboratory tests. read more >>

Hypoxemia can be defined as a condition where arterial oxygen tension or partial pressure of oxygen (PaO2) is below normal (normal value is between 80 and 100 mmHg). On the other hand, hypoxia is defined as the reduction of oxygen supply at the tissue level, which is not measured directly by a laboratory value.read more >>
