  2. Hypovolemic shock - Wikipedia

    en.wikipedia.org/wiki/Hypovolemic_shock

    In the setting of head or neck trauma, an inadequate sympathetic response, or neurogenic shock, is a type of distributive shock that is caused by a decrease in peripheral vascular resistance. [3] This is suggested by an inappropriately low heart rate in the setting of hypotension. [ 3 ]

  3. Vasodilatory shock - Wikipedia

    en.wikipedia.org/wiki/Vasodilatory_shock

    In the cases of cardiogenic shock resulting from heart failure or acute hemorrhagic shock caused by a large volume of blood loss, the body constricts peripheral vessels to reverse the low arterial pressure that causes inadequate tissue perfusion. [22] With vasodilatory shock, it is difficult for the peripheral vascular smooth muscle to ...

  4. Shock (circulatory) - Wikipedia

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

    The diagnosis is generally based on a combination of symptoms, physical examination, and laboratory tests. [2] A decreased pulse pressure (systolic blood pressure minus diastolic blood pressure) or a fast heart rate raises concerns. [1] Shock is a medical emergency and requires urgent medical care.

  5. Distributive shock - Wikipedia

    en.wikipedia.org/wiki/Distributive_shock

    The main goals of treatment in distributive shock are to reverse the underlying cause and achieve hemodynamic stabilization. [9] Immediate treatment involves fluid resuscitation and the use of vasoactive drugs, both vasopressors and inotropes . [ 10 ]

  6. Hypovolemia - Wikipedia

    en.wikipedia.org/wiki/Hypovolemia

    Peripheral vasoconstriction accounts for the cold extremities (hands and feet), increased heart rate, increased cardiac output (and associated chest pain). Eventually, there will be less perfusion to the kidneys, resulting in decreased urine output.

  7. Acute decompensated heart failure - Wikipedia

    en.wikipedia.org/wiki/Acute_decompensated_heart...

    Cardiac symptoms of heart failure include chest pain/pressure and palpitations.Common noncardiac signs and symptoms of heart failure include loss of appetite, nausea, weight loss, bloating, fatigue, weakness, low urine output, waking up at night to urinate, and cerebral symptoms of varying severity, ranging from anxiety to memory impairment and confusion.
