NR 601-Week 1 Note
PFT interpretation:
Step 1
FEV1 normal 80% -120% , FVC 80% -120%, FEV1/FVC ratio >70%
Step 2
Gold 1 (mild) EFV1 > or equal 80% predicted
Gold 2 (Moderate) EFV1 > 50-79% predicted
Gold 3 (severe) EFV1 > 30-49% predicted
Gold 4 (very severe) EFV1 < 30 predicted
Step 3
Reversibility: Reversibility is measured by pre and post bronchodilator spirometry test
Spirometry—short acting bronchodilator- repeat test 10-15 mins after--- significant response in
adult is considered > or equal to 12% improvement in EFV1 or FVC and an absolute
improvement of > or equal 0.2L (This indicate Asthma)
COPD:
Global initiative for COPD (GOLD) criteria: Consider COPD in any patient with the following:
Dyspnea, Chronic cough or sputum production, and/or exposure to any of the previous risk
factors (Smoking, occupational exposure) non modifiable risk factor such as age >40, alpha 1
antitrypsin deficiency and other childhood severe lung infection, h/o TB, low socio-economic
status, and GERD.
Assessment Criteria:
Dyspnea (progressive, worse with exercise, increased effort to breath)
Chronic cough (intermittent or nonproductive)
Chronic sputum production (any pattern)
Histories of exposure to risk factors (smoke, occ. Dust, chemical, fumes, or smoke from cooking
or heating fuels)
Exam: decrease breath sound, wheezes at base, cyanosis, leaning forward with arm support, use
of accessory muscle, neck vein distension
Diagnosis: Spirometry is the gold standard because it helps to distinguish the stage. Can perform
both pre and post bronchodilator. Irreversible airflow limitation I the hallmark of COPD.
Treatment:
