wk 2 COPD ppt/1 Flashcards
what can cause emphysema
2
- cigs
2. steroids
COPD leading cause of death
3rd
RF - hypercapnic
PaCO2 > 45 mmHg and pH < 7.35
continual bronchial irritation and inflammation leads to
CB
COPD - keep sats where
> 90%
one of the first signs of hypoxemia
restlessness
rhonchi and coughing is to
CB
50/50 club
CO2 and bicarb will be in the 50s
ABGs of COPD patients
pH - normal
CO2 - high
bicarb - high
RF - hypoxemic
Pa02 < 60 mmHG on 60% oxygen
COPD blood vessels
thicken
doesn’t get SOB while eating
CB
what is a1-trypsin
substance that protects the lungs and liver from enzyme breakdown
COPD alveoli surface area
diminishes
hypercapnic RF aka
ventilatory failure
a1-antitrypsin deficiency leads to a
breakdown of elastin in CT of lungs
Right HF is common in emphysema why
from capillary beds getting thick
right HF emphysema + pulmonary HTN leads to
5
- edema in ankles and legs
- edema in liver
- JVD
- hepatosplenomegaly
- distended stomach
hypoxemic RF aka
oxygenation failure; low oxygen levels
two types of respiratory failure
- hypoxemic
2. hypercapnic
emphysema - why the weight loss?
3
- sores in mouth
- don’t taste as much
- too short of breath to eat
obstructive pulmonary disorders stem from
increased resistance to airflow
COPD - if CO2 retainer, what is oxygen sat usually kept at
about 88%
COPD primary process is
inflammation; inhalation of noxious particles
