Lunc Capacities/ Pulmonary DD Flashcards
FEV1?
Forced expiratory Volume in 1 second
-used to diagnose obstructive diseases
Residual volume?
The amount of air remaining in lungs once expiration has occurred
Functional residual capacity?
ERV+RV
Obstructive: overall is effected ERV and RV decreased
Restrictive: NOT AFFECTED IN THIS CONDITION
Vital capacity?
TV+IRV+ERV
Obstructive: TV and ERV are decreased
Restrictive: Inspiratory reserve volume decreased
Total lung capacity
TV+IRV+ERV+RV
Obstructive: RV is increased
Restrictive: all decreased
Inspiratory capacity
TV+IRV
Obstructive: not affected
Restrictive: IRV decreased
What are the obstructive pulmonary DD?
COPD, Emphysema, Chronic bronchitis
What are the restrictive DD?
Idiopathic disease, sarcoidosis, occupational exposure, pregnancy
SCI breathing C3,4,5
Portable respiratory
SCI breathing T1-6
Stage 1 Gold stage COPD ?
-FEV1 > = 80
-With or without symptoms
-Sputum production
GOLD Classification COPD Stage 2
Moderate
FEV1 50-80%
SOB with exertion
W/ or w/o cough and sputum
Gold Classification COPD Stage 3
Severe
FEV1 30-50%
Greater SOB with exertion
Decreased exercise capacity, fatigue, repeated exacerbations disease
Gold Classification COPD Stage 4
Very severe
FEV1 <30% or FEV1 <50%
Chronic respiratory failure
What is COPD?
Slowly progressing, chronic disease that limits expiratory airflow due to abnormalities in alveoli or airways usually from environmental exposure (smoking or pollutions)
