Signs and symptoms of shock include passing out or losing consciousness, feeling dizzy or lightheaded, accelerated breathing even while at rest, and weakness or difficulty standing up, according to WebMD. Other symptoms include lack of alertness, confusion, restlessness and inability to respond to questions.
Shock is a medical condition that is characterized by the body and its functions shutting down when it is unable to supply enough blood to vital organs, such as the heart or the brain, notes Healthline. Types of shock include cardiogenic, which involves heart damage that causes reduced blood flow; anaphylactic, caused by an allergic reaction; septic, the result of bacteria in the bloodstream; and hypovolemic, brought on by blood loss. Shock has many causes, including dehydration, low blood pressure, heart failure and nerve damage.
Shock is an extremely serious condition and requires immediate medical attention. Treatment options include lying the patient down and elevating the legs and feet, avoiding unnecessary movement and keeping the patient as still as possible, initiating CPR if the patient displays no visible signs of life, loosening clothing, and covering the patient with a blanket to maintain comfort, explains Mayo Clinic. Should the patient experience vomiting or bleeding from the mouth, he must be turned on his side to prevent the risk of choking.
