😱 Types of Shock Flashcards
Cardiogenic Shock
Heart’s inability to pump effectively, causing reduced blood flow.
MI/CHF
Hypovolemic Shock
Severe blood or fluid loss, reducing blood volume and increased heart rate.
Anaphylactic Shock
A severe allergic reaction causing dialated blood vessels.
Septic Shock
Severe infection, dilating blood vessels and causing low blood pressure.
The body releases histamines when an infection is detected, which dialate the vessels to increase blood flow to the infected area.
Neurogenic Shock
Nerve damage or spinal injury, causing blood vessel dilation.
Not from histamines. The dilation is due to the lack of nerve signals that normally keep the blood vessels constricted.
Obstructive Shock
Obstructed blood flow, preventing normal circulation.
Distributive Shock
Blood vessels relax too much, lowering blood pressure.
Phsycogenic Shock
Emotional stress or trauma, causing fainting. From reduced blood flow to the brain.
What are the three sub-shocks of Distributive Shock?
- Anaphylactic Shock
- Septic Shock
- Neurogenic Shock
What does every patient in shock receive?
Rapid Transport → O₂ + Keep Warm
(Let hospital know shock patient incoming immediately)
What do dilated blood vessels cause?
Low Blood Pressure
What is the main sign a patient is in shock?
Low Blood Pressure
What are three results of obstructive shock?
- Tension Pneumothorax (Air trapped in chest, collapsing lung, compressing heart)
- Pulmonary Embolism (Blood clot blocking pulmonary artery, reducing O₂)
- Cardiac Tamponade (Fluid compresses heart, hindering blood pumping)
What are two common causes of cardiogenic shock?
- Myocardial Infarction (heart attack)
- Congestive Heart Failure (heart can’t pump blood)
What are three common causes of hypovolemia?
- Trauma
- Blood Loss
- Fluid Loss
