EMT Exam 10

Angina Pectoris & Causes *chest pain from ischemia (lack of O2) to cardiac muscle , difficult to distinguish between angina pectoris and myocardial infarction
Coronary Artery Disease (CAD) *condition that reduces blood flow through the coronary arteries to the heart muscle
Shock *inability for the blood to circulate throughout the body to cells and provide: 02, glucose, removal of waste. When cells can't circulate hypoperfusion syndrome shock can develop
What are the stages of shock? Compensated, Decompensated and irreversible shock
What is compensated shock? heart rate and respiratory rate may increase but patient will continue to perfuse
What is decompensated shock? compensating mechanisms begin to fail and heart rate and respiratory rate initially increase but blood pressure will drop, and patient will exhibit more severe signs and symptoms of shock.
What is irreversible shock? no resuscitative effort will preserve life
Classifications of shock Hypovolemic (classic) shock, obstructive, cardiogenic and distributive shock.
What is hypovolemic (classic) shock? the standard by which other forms of shock are diagnosed and treated
What is obstructive shock? blockage prevents blood flow to the heart
What is cardiogenic shock? inadequate pumping of the heart reduces circulation
What is distributive shock? abnormal distribution of blood in the body prevents perfusion
What are the signs and symptoms of decompesated (progressive) shock? breathing slows, becomes labored and is irregular. circulatory- bp decreases and there are weak or absent pulses. skin is ashen, mottled or cyanotic. eyes are dull and pupils are dilated
