Q

Signs and Symptoms of a Heart Attack

A

Main Sign:

  • Persistent chest pain or discomfort described as pressure, squeezing, tightness, aching, constricting or heavy; localized in the center of the chest behind the sternum.
  • Pain can radiate to the shoulder, arm, neck or jaw
  • Pain is constant and not relieved with rest
  • If the pain lasts longer than 10 minutes or presents with other signs of miocardial infarction, seek advanced medical care

Soft Signs:

  • Tiredness
  • Gastric discomfort
  • Flu
  • Mild, unfocused chest pain
  • Pain that comes and goes or gets worse with activity or time

Other Signs:

  • Dyspnea
  • Tachypnea / bradypnea
  • Tachycardia / bradycardia
  • Cyanosis
  • Profuse Sweating (Hyperhydrosis)
  • Nausea / Vomiting (Emesis)

Q

Congestive Heart Failure

A

When the heart loses it’s pumping ability; the left ventricle doesnt pump as effectively due to chronic hypertension and blood backs up causing pulmonary edema.

  • Pale, Cool, Clammy Skin
  • Panic, restlessness, agitation
  • Hypertension

19
Q

Right Sided Heart Failure

A

Usually occurs with left sided heart failure and causes blood to back up in the veins, resulting in swelling of the extremities.

20

21
Q

Cardiac Arrest

A

When the heart stops beating or beats too irregularly or too weak to circulate blood effectively.

22
Q

Signs and Symptoms of Cardiac Arrest

A
  • Unconscious
  • No Breathing
  • No Pulse
23
Q

Care for Cardiac Arrest

A
  • Cardiopulmonary Resuscitation
  • Defibrillation
  • Advanced Medical Care
24
Q

Normal Sinus Rhythm

A

The normal conduction of electrical impulses without any disturbances.

25
Q

Ventricular Tachycardia

A

Arrhythmia of the heart in which the heart muscle contracts too quickly for adequate pumping

26
Q

Ventricular Fibrillation

A

Arrhythmia in which the heart muscle quivers rather than pump

27
Q

Asystole

A

Absence of electrical activity in the heart. AED is unable to shock

28
Q

Using an AED on hypothermic patient

A

Check the pulse for 45 seconds

Give only one shock

29
Q

AED Pad Placement - Pacemakers and Implanted Cardioverter-Defibrillators

A
  • Reposition electrodes at least 2.5 centimetres away

- Allow the ICD time to finish delivering a shock before delivering a shock from the AED

30
Q

Pad Placement - Trauma

A

Place pads on the chest if the trauma does not interfere with placement.

31
Q

AED precautions

A
  • Remove jewelry before AED use

- Do not use or administer an AED in water, wet surfaces or in rain

32
Q

CPR compression depth

A

Adult: At least 5cm
Child: At least 5cm or 1/3 - 1/2 chest depth
Infant: At least 4cm or 1/3 - 1/2 chest depth

33
Q

CPR Compression : Breath Ratio

A

30:2 for all

34
Q

Transient Ischemic Attack

A

(Angina for the brain) A temporary reduction of blood flow to part of the brain.

35
Q

Cerebrovascular Accident

A

A Stoke; A disruption of blood flow to the brain that is sever enough to cause damage

36
Q

The Types of Stroke

A

Embolic
Thrombolic
Hemhorrage

37
Q

Embolic Stroke

A

Embolism carried by the blood vessels becomes trapped

38
Q

Thrombolic Stroke

A

Thrombus carries by the blood vessels becomes trapped

39
Q

Hemhorrage

A

Bleeding from a ruptured artery in the brain

A tumor or swelling can also lead to a stroke by compressing an artery

40
Q

Signs and Symptoms of TIA and Stroke

A
  • Sudden Weakness
  • Difficulty Talking
  • Blurred or Dimmed vision
  • Unequal Pupil size
  • Sudden, severe headache

  • Incontinence
41
Q

F A S T

A

Facial numbness or weakness
Arm numbness or weakness
Speech is slurred or incomprehensible
Time to get advanced medical help

42
Q

Assessing Stroke

A

Facial Droop
Have the patient show her teeth or smile, it will be abnormal for one side not to move

Arm Weakness
Have the patient close both eyes and hold her arms out straight for 10 seconds.
It will be abnormal for one arm to not move or to drift downward

Speech Abnormalities
Have the patient say “You can’t teach an old dog new tricks”
Incorrect wording, slurring or unable to speak are abnormal signs

43
Q

Care for TIA and Stroke

A
  • Maintain and open airway and care for any life threats
  • If unable to maintain airway, place them on their side to let fluids drain
  • Patient in position of comfort and resting
  • Administer oxygen
  • Obtain advanced medical care
