Disease Process Flashcards
Infectious vs Degenerative Disease
Infectious: when bacteria enters the body
Degenerative: aging process causing tissue to wear down
Acute vs Chronic Disease
Acute: sudden onset-mostly- quick recovery time
Chronic: 6 months or longer, requires ongoing medication and treatment
Describe the 3-step infection process

COPD stands for ?
Chronic Obstructive Pulmonary Disease
What is COPD? What are the 2 main causes of COPD? Symptoms?
group of chronic lung diseases
smoking and air pollution
coughing, hypoxia, dyspnea, fatigue
Reduced supply of oxygen to tissue
hypoxia
Consistently high blood pressure(silent killer)
hypertension
CAD vs Heart Failure
-narrowing of coronary arteries due to plaque buildup, resulting in heart not receiving adequate oxygen and nutrients
-heart not being able to pump adequate amount of blood to the body
Heart Attack(aka?) vs Stroke
