Q

Oxygen

A
  • The most frequently used “drug” in medical emergency
  • The ideal agent for resuscitation of a patient who is unconscious, but still breathing

Q

Postural Hypotension

A

Also referred to as orthostatic hypotension
- a level of altered consciousness that may lead to loss of consciousness
- results from insufficient blood flow to the brain and may occur in a patient immediately after a sudden change in positioning

26
Q

Syncope

A

Caused by an imbalance in the distribution of blood to the brain and to the larger vessels within the body
- this reduced blood flow to the brain causes the patient to lose consciousness

27
Q

What are the psychological factors that can contribute to syncope?

A
  • Stress
  • Apprehension
  • Fear
  • Sight of blood or sight of a certain instrument
28
Q

What are the physiological factors that can contribute to syncope?

A
  • Remaining in one position for a long time
  • Being in a confined environment
  • Skipping meal or being hungry
  • Experiencing fatigue or exhaustion
  • The patient may complain of symptoms and the signs may be noticed for several minutes before the patient loses consciousness
29
Q

Prevention for syncope

A

If patient tells you they feel like they may faint:
- seat them in a supine position
- lie them down and elevate patient’s legs

30
Q

Syncope Management

A
  1. Place patient in supine position with feet elevated slightly
  2. If patient does not respond, call EMS: 911, loosen any constrictive clothing and begin basic life support as required
  3. Provide supplemental oxygen as required
    - nasal cannula
    - nonrebreather mask
  4. Be prepared for vomiting
    - if vomiting occurs turn the patient onto their side to protect their airway
  5. Provide additional treatment as required if other injuries occurred as a result of syncopal episode
31
Q

List a few cardiovascular emergencies

A

1) Angina Pectoris
- chest pain caused by insufficient blood supply or oxygen to the heart
- can be aggravated by exercise, tension, cold weather or large meal

2) Myocardial Infarction (Heart attack)
- the muscles of the heart are damaged because of an insufficient oxygen supply

32
Q

Angina

A
  • Chest pain caused by insufficient blood supply or oxygen to the heart
  • Can be aggravated by exercise, tension, cold weather, or a large meal
  • Patient feels severe chest pain
  • Sensation of severe constriction or pressure on chest
  • Signs and symptoms are similar to myocardial infarction (heart attack)
  • Pain usually lasts 3-8 minutes
    When an attack strikes, it is important to remember that the patient could be having a heart attack
  • Pain relieved or eased promptly by administration of a commonly prescribed drug, nitroglycerin
33
Q

Signs and Symptoms of Angina

A
  • Chest pain (most common)
  • Diaphoresis (sweating)
  • Nausea
  • Pallor (pale)
  • Apprehension (anxiety, fear)
  • Levine sign (holding a clenched fist over chest)
  • Elevated pulse
  • Elevated blood pressure
34
Q

Angina - Management

A
  1. Stop dental treatment
  2. Place the patient in a semi-supine or upright position
  3. Circulation, airway, and breathing should be assessed and monitored
  4. Assist patients with administration of nitroglycerin (vital signs must be taken prior to and after each nitroglycerin administration. NEVER give nitroglycerin if systolic bp is below 90mmHg or 30mmHg below baseline or in patients who are extremely bradycardic (less than 50 bpm) or tachycardic (over 100 bpm)
35
Q

Myocardial Infarction

A

Commonly referred to as a heart attack
- muscles of the heart are damaged because of an insufficient oxygen supply
- if this damage is severe enough, the patient will die; however prompt medical treatment can limit damage to the heart
- any unexplained chest pain should be treated as a potential acute myocardial infarction

36
Q

Signs and Symptoms of Myocardial Infarction

A
  • Chest pain
  • Respiratory
  • Behavioural
  • Pale, cool, diaphoretic skin
  • Nausea, vomiting

37
Q

Myocardial Infarction - Management

A
  1. Call EMS: 911
  2. Stop all patient activity and place the patient in a position of comfort (semi or high fowlers)
  3. Loosen restrictive clothing, especially around the neck and chest
  4. Assess vitals
  5. If patient has a history of angina, assist patients with the administration of nitroglycerin.
    - if no history of angina, nitroglycerin from emergency kit should be administered
  6. Administer high flow oxygen via nonrebreather
  7. Administration of aspirin should be initiated as soon as the symptoms of acute myocardial infarction are identified
  8. If the patient goes into full cardiac arrest, CPR should begin immediately
38
Q

Allergic Reactions

A
  • Can come on suddenly and can easily become life-threatening
  • If symptoms do not subside after initial treatment with antihistamines, call ambulance so that more extensive treatment can be rendered as the patient is transported to the hospital emergency dept.

A

Anaphylaxis or anaphylactic shock

40
Q

  5. Instruct the patient to breathe into cupped hands
46
Q

Asthma

A

A respiratory disorder characterized by the narrowing of the upper airway

Two factors contribute to this narrowing:
1. The bronchial tubes constrict during an allergic-type reaction, severe emotional stress, or presence of infection
2. The mucosa that lines the airway may also become inflamed

  • The constriction and inflammation lead to difficulty breathing, coughing, and wheezing
47

  4. Assess and record vital signs
  5. Call 911 if breathing does not improve after administering medication
49
Q

Cerebrovascular Accident (Stroke)

A

When blood vessels that carry oxygen to the brain are blocked significantly

  • depending on the location of the damage in the brain, a stroke could present as mild or transient loss of concentration, loss of gross or fine motor coordination, loss of speech or vision, or other neurological manifestations
  • Key factor in treating a suspected stroke is to transport the patient as quickly as possible to a hospital’s emergency dept.
50
