Shock
<languages /><translate> Shock is a reduced flow of blood throughout the body, usually caused by severe bleeding or a weak heart; without treatment, can lead to a collapse, coma, and death.
Types[edit | edit source]
- Hypovolemic shock happens when you lose a lot of blood or fluids. Causes include internal or external bleeding, dehydration, burns, and severe vomiting and/or diarrhea.
- Septic shock is caused by infections in the bloodstream.
- A severe allergic reaction can cause anaphylactic shock. An insect bite or sting might cause it.
- Cardiogenic shock happens when the heart cannot pump blood effectively. This may happen after a heart attack.
- Neurogenic shock is caused by damage to the nervous system.
Cardiogenic shock[edit | edit source]
Cardiogenic shock is a serious condition that occurs when your heart cannot pump enough blood and oxygen to the brain, kidneys, and other vital organs. Cardiogenic shock is considered a medical emergency and should be treated immediately. The most common cause of cardiogenic shock is a heart attack. Other health problems that may lead to cardiogenic shock include heart conditions such as heart failure; chest injuries; medicine side effects; and conditions that prevent blood from flowing freely through your heart, such as a blood clot in the lungs.
Without oxygen-rich blood reaching the body’s brain and other vital organs, your blood pressure drops, your pulse slows, and you may experience confusion, loss of consciousness, sweaty skin, and rapid breathing.
Treatment aims to restore blood flow and protect organs from damage. Options include medicines, heart procedures and surgery, and medical devices. Some people may need a heart transplant or a permanently implanted device to help maintain blood flow after cardiogenic shock. If cardiogenic shock was caused by problems in the lungs or by medicine side effects, your doctor will treat those problems. If not treated quickly, cardiogenic shock can lead to life-threatening organ failure or brain injury. </translate>
