Flashcards in Mod 4 Cardiac Emergencies Deck (32):
1

Acute Coronary Syndrome

-Sometimes known as cardiac compromise.
-A blanket term
that refers to anytime the heart is not getting enough oxygen.

2

Tachycardia

-A pulse rate faster than 100 beats per minute.

3

Bradycardia

-A pulse rate slower than 60 beats per minute.

4

Hypotensive

-Systolic blood pressure less than 90

5

Hypertensive

-Systolic blood pressure greater than 140 or diastolic blood pressure greater than 90.

6

Acute coronary syndrome signs and symptoms

-Pain, Pressure, or discomfort in the chest or upper abdomen (Epigastrium)
-Difficulty breathing
-Palpitations
-Onset of nausea, vomiting, or sweating
-Anxiety (feeling of impending doom)
-Weakness
-Abnormal pulse
-Abnormal blood pressure

7

When to give a repeat dose of nitroglycerin

-Patient experiences no or partial relief
-Systolic pressure remains greater than 90 to 100.
-Medical direction requires additional dosage.

8

When to give a patient asprin

-Has no history of asthma
-Not already taking medications that prevent clotting of the blood.
-No contraindications to asprin.

9

Coronary Artery Disease (CAD)

-When coronary arteries become narrowed or blocked.
-Build up of fatty on artery inner walls.
-There are things that can be done to prevent CAD.
-Change in diet, stop smoking, weight loss to lower blood pressure.

10

Myocardiam

Heart muscles

11

Aneurysm

-The dilation, or ballooning, of a weakened section of the wall of an artery
-Artery can burst causing rapid life threatening internal bleeding.
-Common sites are in the aorta and brain.

12

Occlusion

-Blockage, as an artery, by fatty deposits.

13

Thrombus

-A clot formed of blood and plaque attached to inner artery or vein wall.

14

Embolism

-Blockage of a vessel by a clot or foreign material brought by blood current.

15

Dysrhythmia

-A disturbance in the heart rate and rhythm.
-An electrical malfunction of the heart can result in dysrhythmia.

16

Angina Pectoris

-Pain in chest when blood to heart is reduced and portion of heart muscle is not receiving enough oxygen.
-Advised to take Nitroglycerin.

17

Acute mycardial infarction (AMI)

-The myocardium dies as a result of oxygen starvation.
-Often called a heart attack.

18

Sudden death

-A cardiac arrest that occurs within 2 hours of onset of symptoms.
-May have no prior symptoms.

19

Congestive heart failure (CHF)

-Failure of heart to pump efficiently leading to build up of fluids or blood in the lungs, body, or both.
-Causes edema (swelling)
-Caused by diseased heart valves, hypertension.

20

Pedal Edema

-Accumulation of fluid in the feet or ankles.

21

Chain of survival

-Immediate recognition
-Early CPR
-Rapid defibrillation
-Effective advanced life support
-Integrated post cardiac arrest care

22

Types of AED

-Semi automatic. The more common type. Prompts user to press a button to administer a shock through pads.
-Fully automatic. Does not advise a shock and sends a shock automatically once enough energy has been accumulated.

23

Ventricular fibrillation (VF)

-Hearts electrical impulses disorganized preventing heart muscles from contracting normally.
-Shockable rhythm

24

Ventricular tachycardia (V-tach)

-Heart beat is rapid. Does not allow hearts chambers to refill with enough blood between beats.
-Shockable rhythm.

25

Pulseless electrical activity (PEA)

-Electrical rhythm is normal but yet mechanical pumping activity fails to follow electrical activity.
-Non-Shockable rhythm

26

Asystole

-A condition in which the heart has ceased generating electrical impulses.
-Commonly known as flatline
-Non-shockable rhythm

27

AED cardiac arrest treatment sequence for shock indicated (SI)

-Deliver 1 shock if indicated
-If patient does not wake up do 2 mins or 5 cycles of CPR.
-Press analyze button
-Deliver shock if indicated
-After 3 shocks prepare for transport.

28

AED cardiac arrest treatment sequence for no shock indicated (NSI)

-Do 2 mins or 5 cycles of CPR
-Press analyze button
-No shock indicated
-Perform 2 mins or 5 cycles of CPR

29

When to transport patient

-You have administered three shocks
-You have received 3 consecutive NSI messages separated by 2 mins of CPR
-Patient regains pulse

30

Do not defibrillate

-If anyone is touching patient
-If patient is wearing nitro patch
-If patient is lying under water (Dry patient)
-If patient is touching metal

31

The only contraindication to using defib pads

-If pads wont fit on patient without touching each other.

32

Implants and surgeries

-Cardiac pacemaker
-Implanted defibrillator
-Ventricular assist device
-Cardiac bypass surgery
