  2. Hunting reaction - Wikipedia

    en.wikipedia.org/wiki/Hunting_reaction

    Approximately five to ten minutes after the start of cold exposure, the blood vessels in the extremities will suddenly vasodilate. This is probably caused by a sudden decrease in the release of neurotransmitters from the sympathetic nerves to the muscular coat of the arteriovenous anastomoses due to local cold. This cold-induced vasodilation ...

    When resulting from blood loss, trauma is the most common root cause, but severe blood loss can also happen in various body systems without clear traumatic injury. [3] The body in hypovolemic shock prioritizes getting oxygen to the brain and heart, which reduces blood flow to nonvital organs and extremities, causing them to grow cold, look ...

    en.wikipedia.org/wiki/Flammer_syndrome

    Flammer syndrome is a described clinical entity comprising a complex of clinical features caused mainly by dysregulation of the blood supply. It was previously known as vascular dysregulation. [1] It can manifest in many symptoms, such as cold hands and feet, and is often associated with low blood pressure.

  5. Vasodilatory shock - Wikipedia

    en.wikipedia.org/wiki/Vasodilatory_shock

    When the blood vessels suddenly relax, it results in vasodilation. In vasodilatory shock, the blood vessels are too relaxed leading to extreme vasodilation and blood pressure drops and blood flow becomes very low. Without enough blood pressure, blood and oxygen will not be pushed to reach the body's organs.

  6. Vasodilation - Wikipedia

    en.wikipedia.org/wiki/Vasodilation

    When blood vessels dilate, the flow of blood is increased due to a decrease in vascular resistance and increase in cardiac output [further explanation needed]. Vascular resistance is the amount of force circulating blood must overcome in order to allow perfusion of body tissues. Narrow vessels create more vascular resistance, while dilated ...

    The hands typically get cold when the body or the hand specifically is exposed to cold.” Most of the time cold hands aren’t a cause for concern — they’re simply the result of less blood ...

  8. Shock (circulatory) - Wikipedia

    en.wikipedia.org/wiki/Shock_(circulatory)

    The severity of hemorrhagic shock can be graded on a 1–4 scale on the physical signs. The shock index (heart rate divided by systolic blood pressure) is a stronger predictor of the impact of blood loss than heart rate and blood pressure alone. [11] This relationship has not been well established in pregnancy-related bleeding. [12]
