Trace a drop of blood
Sup / Inf Vena Cava
What is Arteriosclerosis
Narrowing of the arteries caused by hardening/thickening of arterial walls (loss of elasticity)
What is Agina Pectoris
Heart's blood supply temporarily cut off
Caused by ischemia to the heart muscle
Commonly following strenuous activity
Increased oxygen intake
Insufficient oxygen to the heart that leads to cell infarction
Results from persistent ischemia
What is Congestive Heart Failure (CHF)
Inability of one or both sides of heart to pump blood out
Cardiogenic Shock (pump failure)
Commonly presents with pulmonary edema and/or edema in the ankles, hands, or feet
What are symptoms of Cardiac Compromise
Sudden onset of weakness, nausea, and sweating
Chest pain or discomfort
Pain in lower jaw, arms, or back
Anxious or irritable
Feeling of impending doom
What are types of pain
i.e. cut finger
Cannot be localized
Typical cardiac pain
What is a pacemaker
Pulse generator and wires to the heart.
Externally can be seen and felt under the skin
What is a AUTOMATED INTERNAL CARDIAC DEFIBRILLATOR (AICD)?
In patients with recurrent arrhythmias.
Wires attached directly to the heart.
Senses an "event" and delivers a shock.
Only requires 5-15 joules.
What is a Normal Sinus Rhythm?
NSR is a "happy" rhythm
If part of the heart becomes injured or dies (i.e. heart attack), the electrical conduction system can become damaged and it can compromise the mechanical function as well.
An "Irritated" Heart?
An irritated heart may show "funny little beats."
These are called Premature Ventricular Complexes.?
What are the 2 Shockable rhythms?
Pulseless Ventricular Tachycardia (VT) may be the initial rhythm for a patient in cardiac arrest.
Ventricular Fibrillation (VFib) is the most frequent rhythm present when a patient is found in cardiac arrest.
What is V Tach?
AEDs can also detect Ventricular Tachycardia (aka V-Tach).
It is similar to V-fib but (unlike V-fib) it has an organized rhythm can sometimes have a pulse
What is V Fib
V-Fib is an unorganized electrical rhythm which interferes with the heart's normal pumping activity.
V-Fib is a useless quivering of the heart that results in no blood flow, therefore no pulse.
Immediately after shocking with the AED, your next step is to __________.
Begin CPR. (Follow prompts of your AED)
Before delivering a shock, you must say, "________" while looking around the patient
I'm clear, you're clear, everybody clear!
As an EMT, you are granted STANDING ORDERS to deliver ______ number of shocks with a LP 12 / 15.
As an EMT, you are granted STANDING ORDERS to deliver ______ number of shocks with a LP 1000.
If you had a patient who is found pulseless and unresponsive at a pool. No CPR has been initiated prior to your arrival. Should you initiate CPR or connect an AED first?
CPR, then connect AED
The correct position on the adult patient for the electrodes with the AED is ___ and _____.
Apex - Sternum
One of three things must occur before you transport the patient connected to the AED. They are:
1.3 shocks are delivered
2.Three "No Shock Advised"
3.Patient regains a pulse
You are transporting a patient in the ambulance, when the patient collapses. What do you do FIRST?
Reassess Initial Assessment(LOC & ABCs)
You arrive to assist a patient in cardiac arrest with an AICD. What do you do?
Treat them the same, just try not to put the AED pads directly over the AICD
