Shock occurs when inadequate blood flow threatens the function of multiple organs. Shock is a potentially life-threatening condition. The sooner it is treated, the better the outcome. If you suspect someone is in shock, call for medical help right away.
Some causes of shock include:
Factors that may increase your chance of shock include:
- Pre-existing heart or blood vessel disease
- Impaired immunity
- Severe allergies
- Severe trauma
The symptoms of shock depend on the cause.
Symptoms may include:
- Altered mental status
- Cool and clammy skin
- Pale or mottled skin color
- Low blood pressure
- Decreased urination
- Weak and rapid pulse
- Slow and shallow or rapid and deep breathing
- Lackluster (dull) eyes
- Dilated pupils
- High or low body temperature
A physical exam will be done.
Tests may include the following:
- Breathing assessment
- Blood pressure measurement
- Heart rate monitoring
- Other testing depending on the cause of shock
- Blood tests and cultures
- Imaging studies
Treatment options include the following:
If you are having trouble breathing, your doctor will clear your airway. Oxygen and breathing assistance may be provided if you need it.
Optimizing Blood Pressure and Heart Rate
You will receive an IV for fluids and/or blood transfusions. These will stabilize your blood pressure and heart rate.
You may be given vasopressors. These medications constrict your blood vessels to increase blood pressure. Drugs may also be used to increase your heart contractions. Other medications may be used depending on the underlying cause.
To help reduce your chance of shock:
- Prevent or control heart or vascular disease.
- Avoid activities that put you at risk of falls or other injuries.
- Carry an epinephrine pen with you if you have a severe allergy.
- Manage conditions, such as diabetes, as advised by your doctor.
