|
Atherosclerosis
|
Damage to endothelium->inflammation->fatty streak->fibrous plaque->complicated lesion
|
|
|
Arteriosclerosis
|
Chronic disease characterized by abnormal thickening and hardening of the vessel walls.
|
|
|
Embolism
|
Can consist of fat, bacteria, foreign substances or air.
|
|
|
Pathogenesis of ACS
|
Atherosclerotic plaque ruptures->thrombus formation over lesion plus vasoconstriction of vessel->unstable angina or MI
|
|
|
Importance of seeking help stat with MI
|
After 20 minutes of ischemia, cellular death and tissue necrosis occurs.
|
|
|
Acute Pericarditis
|
Sudden chest pain that increases with respirations & lying down. May c/o anxiety dysphagia, restlessness, irritability & weakness.
|
|
|
What is happening in cardiac tamponade
|
Cardiac compression caused by fluid.
|
|
|
Heart Failure
|
A general term used to describe several types of cardiac dysfunctions that result in inadequate perfusion of tissues.
|
|
|
Shock
|
The common pathway in all types is impaired cellular metabolism – cells switch from aerobic to anaerobic metabolism.
|
|
|
Hypercapnia
|
Increased carbon dioxide in the arterial blood.
|
|
|
Hypoxemia
|
Reduced oxygenation of arterial blood.
|
|
|
Hypoxia
|
Reduced oxygenation of cells in tissues.
|
|
|
Acute Respiratory Failure
|
Inadequate gas exchange where PaO2 ≤ 50 mm Hg or where PaCO2 ≥ 50 with pH ≤ 7.25
|
|
|
Atelectasis
|
Collapse of lung tissue that can usually be prevented (and treated) by deep breathing and using a spirometer.
|
|
|
Emphysema
|
Enlargement and destruction of alveolar walls with loss of elasticity and trapping of air.
|
|
|
Asthma
|
Thick mucus, mucosal edema and smooth muscle spasm causing obstruction of small airways.
|
|
|
Pulmonary Hypertension
|
This condition results from constriction, or tightening, of the blood vessels on the right side of the heart.
|
|
|
Cor Pulomale
|
Right ventricular enlargement caused by chronic Pulmonary Hypertension. It progresses to right ventricular failure if the PH is not reversed.
|
|
|
Chronic Bronchitis
|
Inflammation and thickening of mucous membrane with accumulation of mucus and pus leading to airway obstruction.
