    I know that the standard measurements for restrictive lung dz. is as follows.
    ABG: decrease p02= increase RR, decrease pCO2, increase pH. Is there any way to rank these indicators? Reason I am asking is because I saw a question where the patient has a decrease in pH and an increase in pCO2. :eek:

    I think you are asking the wrong question

    Restrictive lung disease is diagnosed by the pulmonary function tests, the FEV1/FVC being normal or elevated, while the FEV1 and all other lung volumes are decreased.

    The ABG changes in acid-base oriented diseases. While a smaller lung volume may induce an increased respiratory rate to satisfy oxygen requirements, leading to low Co2 and high pH, it is not characteristic, nor diagnostic, of restrictive lung diseases.
