WebChronic obstructive pulmonary disease (COPD) is the collective term for a number of lung diseases that prevent proper breathing.

When the gas reaches the alveoli the partial pressure of oxygen will again decrease as some oxygen is absorbed and CO2 is excreted. The partial pressure at this point in the oxygen cascade can be determined by using the alveolar gas equation. PAO 2 = PIO 2 – PACO 2 /RQ.
