Anatomy and Physiology
What are the hearts 4 chambers?
Right Atrium, Right Ventricle, Left atrium and Left Ventricle.
What is the heart rate of the AV node?
40-60 bpm
Weakness, nausea, sweating, Shortness of breath (dyspnea), Pink, frothy sputum are symptoms of
Acute myocardial infarction
What is the recommended dosage of aspirin?
324 mg
An AED does what to the heart?
Stops the heart so the heart can return to a normal rhythm. i.e. Control alt delete of the heart.
Where does the aorta receive blood from?
The left ventricle
A thromboembolism is a
blood clot floating through blood vessels.
While palpating the radial pulse of a 56-year-old man with chest pain, you note that the pulse rate is 86 beats/min and irregular. This indicates:
dysrhythmia.
What does MONA stand for?
Monitoring, Maintain position of comfort, Oxygen, Nitroglycerin, Aspirin
Where does the green lead go for a 4 lead?
Left Leg or lower left abdomen
What Valve is between the right atrium and right ventricle?
Tricuspid Valve
Atherosclerosis is
the buildup of calcium and cholesterol in the arteries.
A stable angina occurs in response to
exercise or activity that increases oxygen demand.
Nitroglycerin works by
Relaxes blood vessel walls
Increases blood flow and oxygen supply to heart
Decreases workload of heart
Dilates blood vessels
An internal pacemaker does what to the heart?
Helps regulate the heartbeat.
Blood consists of
red blood cells, white blood cells, plasma, and platlets.
hearts lack of oxygen.
Unilateral pulses, sharp chest pain, dizziness, vomiting, abdominal pain, are possible symptoms of
abdominal aortic aneurysm
What are the steps in the chain of survival?
Early recognition and activation of EMS
Immediate bystander CPR
Rapid defibrillation
Basic and advanced EMS
ALS and postarrest care
Recovery
A device used to enhance the pumping of the left ventricle and cause the pt to not have a pulse is a
Left ventricular assist devices (LVADs)
Cardiac output is
the volume of blood that passes through the heart in 1 minute.
How is increased blood delivered to the myocardium?
Dilating the coronary arteries.
Pedal Edema, fatigue, JVD, and possible chronic pulmonary problems are symptoms of
right sided heart failure.
After ROSC you should
Monitor for spontaneous respirations
Provide Oxygen via BVM 10 breaths per minute
Maintain oxygen Saturation
Assess Blood Pressure
Do an 12 Lead EKG
See if pt can follow simple commands

Percutaneous transluminal coronary angioplasty is a
A tiny balloon is inflated inside a narrowed coronary artery.
