Types of Emergency

Pulmonary Embolus
Shock
Diabetic Reactions
Seizure
CVA
Syncope

3

Fainting also called

Syncope

4

Dizziness also called

Vertigo

5

Emergency Cart is also called

“Crash Cart”

6

Medical Imaging Professional’s Role

Preserve life
Avoid further harm to the patient
Obtain appropriate medical assistance as quickly as possible
Must be able to recognize emergency situation and initiate emergency measures

7

What does AED stand for?

automatic external defibrillator

8

What is Glasgow Coma Scale?

Address three (3) areas of neurological functioning
1. Eyes open
2. Motor response
3. Verbal response
Total of 15 pts possible

9

A failure of the circulatory system to support vital body functions
Body’s reaction to illness, trauma or to severe physiologic or emotional stress

Shock

10

Shock is caused by

Loss in body fluid, cardiac failure, decrease blood vessel tone, or an obstruction in blood flow to vital organs

11

4 Classes of Shock

Neurogenic Shock
Hypovolemic Shock
Cardiogenic Shock
Vasogenic Shock

12

Caused by spinal anesthesia or damage to the upper spinal cord
Spinal cord injury, severe pain, neurologic damage
Blood vessels become relaxed and dilated
Pooling of blood in venous system

Neurogenic Shock

13

Caused by loss of blood or tissue fluid
Hemorrhage, burns, prolonged vomiting, diarrhea or medications, GI bleeding, bleeding after surgery
Insufficient amount of fluid & heart unable to pump enough to body

Hypovolemic Shock

14

Caused by a variety of cardiac disorders
Failure of heart to pump an adequate amount of blood to organs
7% of patient die from heart attack – most common cause is cardiogenic shock

Cardiogenic Shock

15

Caused by sepsis, deep anesthesia, or anaphylaxis
Peripheral vascular dilation produced by factors such as toxins that directly affect blood vessels

Vasogenic Shock

16

Most common type of shock encountered in radiology dept is?

Anaphylactic Shock

17

Anaphylactic Shock is also a

Vasogenic shock

18

Anaphylactic Shock may occur

with contrast media administration
Meticulous history/questionnaire form

19

Signs & symptoms of Anaphylactic shock

must be monitored as routine procedure with contrast studies
Alert physician when signs occur (sneezing/itching……call nurse)
Mild/Moderate/Severe reactions

20

Localized itching
Injection site
Urticaria (hives)
Nasal congestion
Sneezing, coughing
Swelling – eyes, face
Tearing of eyes
Flushed, feeling of warmth (common site effect)
Nausea & vomiting

Mild Reaction

21

PE is

Occlusion of a pulmonary arteries by a thrombus
Blood clot forms and becomes lodged in the pulmonary artery

22

Decreased BP
Weak, thready pulse (rapid or shallow)
Bronchospasm, laryngeal edema, severe dyspnea, cyanosis
Dysphasia, abdominal cramping, vomiting, and diarrhea
Seizures, respiratory & cardiac arrest

Severe Reaction

23

Anaphylactic Shock Reaction

Stop the procedure & injection
Do not remove IV access
Notify the radiologist and nursing staff
Obtain crash cart
Place patient in a Semi-Fowler’s position or in a sitting position to facilitate breathing
Document reaction (important)

24

PE stands for

Pulmonary Embolus

25

PE is

Occlusion of a pulmonary arteries by a thrombus
Blood clot forms and becomes lodged in the pulmonary artery
Originates in the lower extremity and travels to the lungs (DVT)

26

PE originates

in the lower extremity and travels to the lungs (DVT)

27

PE caused by

Trauma, surgical procedures (orthopedic & abdominal), pregnancy, CHF, prolonged immobility (airplane or long car rides)
Swelling in lower extremities, pain, sudden onset

28

PE result in

50,000 deaths each year

29

A group of metabolic diseases which result from a disorder of carbohydrate metabolism

Diabetes Mellitus

30

Diabetes Mellitus is caused from

insufficient production of insulin or inadequate utilization of insulin
