OCEMT EMT Cardiology Study Guide
What is the mitral valve? Correct Answer-Located between left atrium
and left ventricle. Allows blood to flow from the lungs into the left
atrium. Prevents backward flow from the left ventricle to the left atrium.
What is the aortic valve? Correct Answer-Located between the aorta and
left ventricle. Allows blood to flow from the left ventricle to the aorta.
Prevents backward flow from the aorta into the left ventricle.
What is the pulmonary valve? Correct Answer-Located between the
right ventricle and pulmonary artery. Allows blood to pump from the
right ventricle to the pulmonary artery. Prevents blood from going
backward from the pulmonary artery to the right ventricle.
What is systolic blood pressure? Correct Answer-Measurement.
Measures blood pressure in arteries when the heart beats.
What is diastolic blood pressure? Correct Answer-Measurement.
Measures blood pressure in arteries when the heart rests.
What is the main function of pulmonary arteries? Correct Answer-
Function. Carries oxygen-poor blood from the heart to the lungs.
What is the depth of compression during CPR? Correct Answer-
Compression depth. 2 inches/5 cm for adults and children. 1.5 inches/4
cm for infants.
, What are the lethal cardiac rhythms that an AED will shock? Correct
Answer-Rhythms. Ventricular fibrillation (V-Fib). Pulseless ventricular
tachycardia (V-Tach).
When should CPR be initiated? Correct Answer-Indications. No definite
pulse within 10 seconds. No breathing or gasping.
Which patients will benefit most from an AED? Correct Answer-
Beneficiaries. Patients in cardiac arrest.
What is PEA? Correct Answer-Definition. Pulseless electrical Activity
(PEA) is a type of irregular heart rhythm. Organized or semi-organized
electrical activity of the heart persists. Product of systemic vascular
resistance and the increase in systemic arterial flow generated by the
ejection of the left ventricular stroke volume is not sufficient to produce
a clinically detectable pulse.
What are the possible abnormal vitals in electrocution patients? Correct
Answer-Possible vitals. Possibility of cardiac arrest.
What are the signs of shock? Correct Answer-Tachypnea, severe
shortness of breath, tachycardia, decreased level of consciousness or
unresponsiveness, weak pulse, hypotension, diaphoresis, cold
extremities, pale skin
