I remmeber that u had posted a question of Acid Base Status in COPD
Can u pls confrim or correct the following:
If the pt has an acute asthma attack -- Initially High PaCo2 -- Resp Acidosis
As this progresses into a Severe Asthma Attack (i.e. Weak of Resp Muscle, the PaCO2 decreases almost to normal) -- Resp Alkalosis
Is this the same concept applied to acute prob in COPD pts as well??
thx.
What is the Acid Base in COPD and how is it if COPD pt has an acute exacerbation?

From what I understand, during an acute COPD exacerbation, the patient is dyspneic, so he is putting a lot of CO2 out, he has low pCO2, so: respiratoty alkalosis. Then later, with exhaustion of the respiratory muscles, he is less dyspneic, pCo2 starts to elevate (retain CO2), so pH starts to normalize, one could think the patient is getting better when actually he is getting worse, is about to have respiratory failure. So normalizing pCO2 and pH is not always a good sign.
Is that what you are asking about?
