COPD Flashcards
Structural changes of the airway and alveoli that results in chronic respiratory symptoms and airflow limitations that is NON-REVERSIBLE
COPD
What two diseases fall under COPD?
Chronic Bronchitis
Emphysema
Patients with COPD typically have a history of?
Smoking
Pathological term describing destruction of gas exchanging surfaces on the lung alveoli resulting in a reduction of normal elastic recoil of the lung parenchyma.
Emphysema
Cough and sputum production for more than 3 months a year for at least 2 consecutive years in the absence of other conditions that might cause symptoms.
Chronic Bronchitis
Do patients with COPD have a difficult time getting air in or out of their lungs?
Out
What is the basis of diagnosis for COPD?
Spirometry
If a patient has reduced FEV1 and the ratio of FEV1/FVC is low, what does this indicate?
Airflow Obstruction
An increase in residual volume and total lung capacity indicates what?
Air Trapping and Hyperinflation
A test used to measure how effectively the lungs transfer oxygen from inhaled air in the blood.
DLCO
What are the indications to measure ABGs?
Hypoxemia or Hypercapnia
FEV1 or DLCO less than 40% of predicted.
Oxygen concentration typically higher in the Alveoli (PA) or in the Arteries of the Lungs (Pa)? By how much?
Alveoli (PA)
5 - 10 mmHg
For a patient with COPD who is an active smoker, what is the primary treatment?
Smoking Cessation
What vaccines can be given to patients with COPD to help prevent exacerbation?
Flu
COVID
Pneumococcal
Post-Bronchodilator FEV1/FVC of less than what would indicate COPD?
Less than 0.7
COPD Gold 1
FEV1 of 80% or greater
COPD Gold 2
FEV1 50 - 79%
COPD Gold 3
FEV1 30 - 49%
