COPD Flashcards
a chronic obstructive pulmonary disease that is generally progressive and may be accompanied by airway hyperactivity
chronic obstructive pulmonary disease
when are chronic bronchitis and emphysema considered “reversible”?
during acute exacerbations
what is emphysema known as?
pink puffer
what is chronic bronchitis known as?
blue bloater
a patient presents with minimal V/Q mismatch since both alveoli and vessels are damaged, no hypoxemia, hypercapnia, hyperventilation to compensate for CO2, and muscle wasting due to decreased cardiac output. what are they likely experiencing?
emphysema
what would chest imaging show for a patient with emphysema? (3)
enlarged lungs
large, irregular bullae
flattened diaphragm
a patient presents with V/Q mismatch since airways are damaged but capillaries are intact, hypoxia, cyanosis, acidosis that leads to cor pulmonale, leading to right heart failure and peripheral edema. what are they experiencing?
chronic bronchitis
what would chest imaging show for a patient with chronic bronchitis? (2)
increased vascular markings
cardiomegaly
what is the #1 risk factor for COPD?
smoking
how would a patient present with COPD that has been present for over 10 years and today they just feel worse? (3)
worsening SOB, cough, and sputum
what can COPD exacerbations lead to?
respiratory distress / failure
what does a COPD exacerbation mimic?
asthma exacerbation
what are most COPD exacerbations triggered by?
respiratory infections
a patient presents with dyspnea worsening with exertion, digital clubbing, chronic productive cough with SOB. what are they likely experiencing?
COPD
what 6 diagnostics should/can be order for a patient with suspected COPD?
blood gas
CBC
spirometry
chest xray
chest CT
doppler echocardiogram
what would be seen in a blood gas for a patient with COPD?
normal pH (compensation)
increased CO2
increased HCO3
