Shock

📖What is Shock?

Shock is a life-threatening medical emergency in which the circulatory system fails to deliver enough oxygen and nutrients to the body's tissues and organs, causing cells to begin malfunctioning and, if uncorrected, leading to organ failure and death. It can result from several distinct underlying mechanisms, including severe blood or fluid loss, as in hemorrhagic shock, the heart's inability to pump effectively, as in cardiogenic shock, widespread infection causing blood vessels to abnormally dilate, as in septic shock, or a severe allergic reaction causing sudden vessel dilation and airway swelling, as in anaphylactic shock. Regardless of the underlying cause, shock represents a critical failure of the body's ability to maintain adequate blood pressure and organ perfusion, requiring rapid identification of the type and immediate, targeted treatment. Untreated shock progresses rapidly through stages of worsening organ dysfunction and can be fatal within a short period.
