Cardiology/Resuscitation Flashcards
You should check a patients pulse for no longer than how many seconds?
10 seconds
What is the adult dose of aspirin?
324mg
After travels through the right atrium, blood goes through which valve into and then into the right ventricle?
Tricuspid valve
Blood flows from the pulmonary veins into where?
Left atrium
How is the pain of angina described?
Pain occurs with exertion and subsides with rest.
In PULMONARY CIRCULATION, what carries oxygenated blood from the lungs to heart and what carries deoxygenated blood from the heart to the lungs?
Veins/Arteries
In SYSTEMIC CIRCULATION, what carries oxygenated blood from the lungs to heart and what carries deoxygenated blood from the heart to the lungs?
Arteries/Capillaries
What is Becks Triad?
Low blood pressure, distension of the jugular veins and decreased or muffled heart sounds on cardiac auscultation. Signs of Cardiac Tamponade.
If a patient becomes unresponsive enroute to the ER and is in cardiac arrest, what should you do?
Request additional resources. Pull over and help partner with CPR.
What are some signs and symptoms of a hypertensive emergency?
Headache, nausea, bounding pulse, epistaxis
If you DO NOT witness a patient going into cardiac arrest, how do you proceed?
5 cycles of CPR then apply AED.
The ascending aorta arises from the left ventricle and consists of two branches, the right and left ______________?
Main coronary arteries
Blood flows from arteries to capillaries through which vascular structure?
Arterioles
Depth of chest compressions
At least two inches not more than 2.4
What is a physical sx associated with cardiogenic shock?
Hives
Symptom most commonly associated with aortic aneurysm?
Chest pain
What is the pericardium?
Fibrous layer surrounding the heart (NOT A COMPONENT OF THE HEART WALL)
What can cause an SPO2 reading to be falsely low?
Ambient Light
What are receptors that respond to changes in BP?
Baroreceptors
What does normotensive mean?
Normal BP
What is considered a high diastolic BP?
Greater than 80
What is the definition of endocarditis?
Inflammation affecting the innermost layer of the heart (endocardium)
The ventricle is responsible for what action?
Pumping blood to the body
If a neonate’s heart rate falls below what value do you start compressions?
60
What is the term that defines force exerted on the ventricle walls at the end of diastole?
Preload
Brain damage after a patient experiences cardiac arrest becomes irreversible after roughly how long?
8-10mins
What is the correct ranking of CPR importance with a pediatric patinet?
Chest compressions, airway, breathing
What is the first action that should be taken when a neonates HR is less than 100bpm?
Administer positive pressure ventilations
The SA node is located where?
Right atria
A bradycardic heart rhythm can be classified as what?
Less than 60bpm
What to do when arriving at a scene with a bystander already doing CPR?
Have them stop and check a pulse
What 3 sx are associated with hypotension?
Pallor, diaphoresis, tachycardia
A combination of difficulty breathing, feet and ankles feel tight, and relief in condition when sitting up suggests what issue?
Chronic heart failure (heart’s inability to pump blood efficiently results in fluid backing up in the lungs and causes difficulty breathing while at rest or lying flat in bed.)
Becks triad is a set of vitals that indicates what condition?
Cardiac Tamponade
Crackles in lungs, peripheral edema, and chest pain suggest what condition?
Congestive heat failure
What type of shock is seen in a patient with a cardiac tamponade?
Obstructive
When providing ventilations to an intubated patient, what is the delivery method?
Deliver each breathe over 1 second at a rate of 8 to 10 breathes per minute
If the tricuspid valve could not close properly, where would blood back up into?
Right atrium
What is the first action taken for a neonate whose HR is less than 100bpm?
Administer positive-pressure ventilations
Automaticity of cardiac cells refers to what?
The cells ability to spontaneously depolarize
What two major vessels does the right atria collect blood from?
Vena Cava
Which structure of the heart has the thickest myocardial section?
Left ventricle
