Q

Asthma

-diagnosis, how to confirm, best way to assess exacerbation

A

H&P, PE findings

CONFIRM diagnosis is w/ PFT– need to stop bronchodilators before test—will show obstructive pattern– decreased FEV1/FVC

best way to assess exacerbation is peak expiratory flow rate

Q

COPD

  • define
  • diagnosis–gold standard
  • labs and why
  • tx—- WHATS THE ONLY TX TO REDCE MORTALITY
A

chronic cough that is productive occuring on most days of 3 months of the year for at least 2 or more consecutive yrs w/o defined acute cause

DX

  • GS—- PFTs—–> show V/Q mismatch and FEV1/FVC ration less than 0.7
  • CXR— only used to r/o pneumonia or pneumothorax… can also be useful in exacerbation

LABS
-incr hgb and hematocrit bc of the chronic hypoxic state

TX
1st step: quit smoking and give pneumococcal vaccine
2. bronchodilators—- anticholinergics, beta ags, corticosteroids
3. OXYGEN IS THE ONLY THERAPY TO REDUCE MORTALITY and quiting smoking
4. alpha 1 anti tyrpsin def— lung transplant only tx
5. azithromycin can be helpful in exacerbations/inflammation
