Medical Emergencies

Heart attack, stroke, seizures, and other critical medical conditions.

Heart Attack

What's Happening

Blood flow to part of the heart is blocked. Heart muscle begins to die.

Time is critical. "Time is muscle."

Recognizing Heart Attack

Classic symptoms:

  • Chest pain or pressure (may feel like squeezing, fullness, or aching)
  • Pain radiating to arm(s), jaw, neck, back, or stomach
  • Shortness of breath
  • Cold sweat
  • Nausea
  • Lightheadedness

Atypical symptoms (more common in women):

  • Unusual fatigue
  • Indigestion
  • Anxiety
  • Back pain
  • Jaw pain without chest pain

Treatment

  1. Call 911 immediately

    • Don't drive to hospital (may need CPR en route)
    • Note time symptoms started
  2. Have person rest

    • Sit in comfortable position
    • Loosen tight clothing
    • Stay calm
  3. Give aspirin

    • If not allergic
    • 325 mg regular aspirin OR 4 baby aspirin (81 mg each)
    • Chew, don't swallow whole
  4. If prescribed nitroglycerin

    • Help them take it
    • Follow their prescription instructions
  5. Monitor

    • Be prepared for cardiac arrest
    • Start CPR if they become unresponsive and not breathing normally
  6. Do NOT

    • Let them "wait and see"
    • Let them drive
    • Give anything other than aspirin/nitro

Stroke

What's Happening

Blood flow to part of the brain is interrupted. Brain cells begin to die.

"Time is brain." Every minute matters.

Recognizing Stroke: FAST

LetterSignHow to Check
FFace droopingAsk them to smile. Is one side drooping?
AArm weaknessAsk them to raise both arms. Does one drift down?
SSpeech difficultyAsk them to repeat a simple sentence. Is it slurred?
TTime to call 911Note what time symptoms started

Other Symptoms

  • Sudden confusion
  • Sudden trouble seeing
  • Sudden trouble walking
  • Sudden severe headache (may indicate bleeding stroke)
  • Sudden numbness (especially one side of body)

Treatment

  1. Call 911 immediately

    • Note EXACT time symptoms started
    • Treatment windows are time-sensitive
  2. Keep calm and reassuring

    • Person may be frightened
    • May not understand what's happening
  3. Position

    • If conscious: Comfortable position, usually semi-upright
    • If unconscious but breathing: Recovery position
  4. Do NOT

    • Give food or water (swallowing may be impaired)
    • Give aspirin (could worsen bleeding stroke)
    • Let them "sleep it off"
  5. Monitor

    • Breathing
    • Level of consciousness
    • Be ready for CPR

Mini-Stroke (TIA)

Symptoms that resolve within minutes to hours.

Still an emergency. TIAs often precede full strokes. Seek immediate medical care.

Seizures

Types

TypeAppearance
Generalized tonic-clonic (grand mal)Stiffening, then jerking, loss of consciousness
AbsenceStaring, brief unresponsiveness
FocalTwitching in one area, may spread
AtonicSudden loss of muscle tone, falls

During a Generalized Seizure

  1. Stay calm
  2. Protect from injury
    • Clear area of hard/sharp objects
    • Cushion head if possible
  3. Time the seizure
    • Important for medical decisions
  4. Do NOT
    • Restrain them
    • Put anything in their mouth
    • Try to hold tongue
  5. Turn on side when jerking stops
    • Helps drain secretions
    • Recovery position

After the Seizure

Postictal state (after-seizure confusion):

  • May be confused, tired
  • May not know what happened
  • Stay calm and reassuring
  • Stay with them until fully alert

Call 911 If
