Pulmonary Flashcards
what is the function of the lunges
transport O2 into air sacs (alveoli) and transport CO2 from the tissues to the atmosphere
ventilation equation
TV x RR
with activity, both increase
chronic bronchitis
-over production of mucus causes an occlusion of airways
-blue bloaters
emphysema
-destruction of elastic fibers in lungs can keep O2 sat high usually
-pink puffers
causes of emphysema
-heredetary
-smoking
s/s of COPD
-SOB
-DOE
-orthopnea
-wheezing
-increased RR
- peripheral cyanosis
-digital clubbing
-pursed lip breathing
-elbow changes
-malaise
-chronic cough
-barrel chest
-weight loss
-accessory muscles to expiration
-prolonged epxiration
-decreased FEV1/FVC ratio
-anxiety
-depression
what is the differential test for function of the lungs
pulm function tests being FVC, FEV1, FEV1/FVC
exercise and COPD
-obstructive disease impedes lung emptying (requires more time)
-increased breathing leads to hyperinflation and smaller TV
- impairment of gas exhcange
restrictive lung disease
-diminished lung volune
-NM disorders, chest wall disorders, pleural disorders
pathologies/conditions affecting pulmonary circulation
-body position
-stenosis or incompetence of heart valves
-CHF
-PE
supplemental oxygen
if oxygen saturation <88%, then oxygen supp necessery to improve survival and cognition
