EMT - Types of Shock

Cardiogenic

Caused by inadequate function of the heart, or pump failure

Examples:

Heart Attack / MI, Congestive Heart failure, Infection, abnormal heart rhythms, valvular disease

(Pump Failure)

Obstructive

Results when conditions that cause mechanical obstruction of the cardiac muscle also impact pump function

Causes: Cardiac Tamponade, Pulmonary Embolism, Tension Pneumothorax

(Pump Failure)

Septic Shock

Occurs as a result of severe infections, usually bacterial

Notes: plasma leaks out of the vascular system and normally into respiratory system, and causes huge vasodilation

(Pipe Problem)

Neurogenic Shock

Result of damage to spinal cord, particularly at the upper cervical levels, may cause significant injury to the part of the nervous system that controls the size and muscular tone of the blood vessels

(Pipe Problem)

Anaphylactic Shock

Occurs when a person reacts violently to a substance to which he or she has been sensitized

Histamine causes widespread vasodilation

(Pipe Problem)

Psychogenic Shock

Occurs because a patient has had a sudden reaction of the nervous system that produces a temporary, generalized vascular dilation, resulting in fainting or syncope

Causes: brain aneurysm, receiving of bad news

(Pipe Problem)

Hemorrhagic Shock

Result of an inadequate amount of fluid or volume in the system

Causes: Trauma, Burns

(Blood Problem)

Non-hemorrhagic Shock

Result of an inadequate amount of fluid or volume in the system

Causes: Dehydration, Vomiting, Diarrhea,

(Blood Problem)
