- An extreme, possibly life-threatening systemic allergic reaction that may include shock and respiratory failure.
- A swelling or enlargement of a part of an artery, resulting from weakening of the arterial wall.
autonomic nervous system -
- The part of the nervous system that regulates functions, such as digestion and sweating, that are not controlled voluntarily.
cardiogenic shock -
- A state in which not enough oxygen is delivered to the tissues of the body, caused by low output of blood from the heart. It can be a severe complication of a large acute myocardial infarction, as well as other conditions.
compensated shock -
- The early stage of shock, in which the body can still compensate for blood loss
- A bluish-gray skin color that is caused by reduced levels of oxygen in the blood.
decompensated shock -
- The late stage of shock, when blood pressure is falling.
- A state in which fluid losses are greater than fluid intake into the body, leading to shock and death if untreated.
- The presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area.
- A balance of all systems of the body
- A condition in which the internal body temperature falls below 95 degrees F (35 degrees C) after exposure to a cold environment.
hypovolemic shock -
- A condition in which low blood volume, due to massive internal or external bleeding or extensive loss of body water, results in inadequate perfusion.
irreversible shock -
- The final stage of shock, resulting in death.
neurogenic shock -
- Circulatory failure caused by paralysis of the nerves that control the size of the blood vessels, leading to widespread dilation; seen in spinal cord injuries.
- The circulation of oxygenated blood within an organ or tissue in adequate amounts to meet the cells'' current needs.
psychogenic shock -
- Shock caused by a sudden, temporary reduction in blood supply to the brain that causes fainting (syncope).
- Developing a sensitivity to a substance that initially caused no allergic reaction.
septic shock -
- Shock caused by severe infection, usually a bacterial infection.
- A condition in which the circulatory system fails to provide sufficient circulation so that every body part can perform its function; also called hypoperfusion.
- Circular muscles that encircle and, by contracting, constrict a duct, tube, or opening.
- Fainting spell or transient loss of consciousness.
