Hypovolemic shock is a form of shock caused by severe hypovolemia (insufficient blood volume or extracellular fluid in the body). [1][2] It can be caused by severe dehydration or blood loss. [3][2] Hypovolemic shock is a medical emergency; if left untreated, the insufficient blood flow can cause damage to organs, leading to multiple organ failure.
Hypothermia is defined as a body core temperature below 35.0 °C (95.0 °F) in humans. [ 2 ] Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. [ 3 ] In severe hypothermia, there may be hallucinations and paradoxical undressing, in ...
Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. [ 1 ] Hypoxia may be classified as either generalized, affecting the whole body, or local, affecting a region of the body. [ 2 ] Although hypoxia is often a pathological condition, variations in arterial oxygen ...
Neurology. Neurogenic shock is a distributive type of shock resulting in hypotension (low blood pressure), often with bradycardia (slowed heart rate), caused by disruption of autonomic nervous system pathways. [1] It can occur after damage to the central nervous system, such as spinal cord injury and traumatic brain injury.
t. e. Normal human body temperature (normothermia, euthermia) is the typical temperature range found in humans. The normal human body temperature range is typically stated as 36.5–37.5 °C (97.7–99.5 °F). [8][9] Human body temperature varies. It depends on sex, age, time of day, exertion level, health status (such as illness and ...
Human thermoregulation. As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [ 1 ] Humans have been able to adapt to a great diversity of climates, including hot ...
35094-2. Blood pressure (BP) is the pressure of circulating blood against the walls of blood vessels. Most of this pressure results from the heart pumping blood through the circulatory system. When used without qualification, the term "blood pressure" refers to the pressure in a brachial artery, where it is most commonly measured.
Chronic kidney disease. Chronic kidney disease (CKD) is a type of long-term kidney disease, in which either there is a gradual loss of kidney function occurs over a period of months to years, or abnormal kidney structure (with normal function). [2][5] Initially generally no symptoms are seen, but later symptoms may include leg swelling, feeling ...
