What causes sudden shock?

Could it be caused by cerebral ischemia or malformation of blood vessels in the brain, it is recommended to do a CT examination.

There is also the uncommon form of feigned death, which has an ultra-low incidence.

Shock is an abnormal pathophysiological condition that endangers human life. There are many causes of shock, including: 1. Distributed shock

It accounts for about 66%, of which septic shock accounts for 62%, and the chance of death can reach 50%; 2. Cardiogenic shock: about 17%, which is related to impaired cardiac function; 3. Hypovolemic shock: about 16%, which is caused by the reduction of blood supply due to blood loss; 4. Obstructive shock:

About 2%. Once shock is detected, you should go to the hospital for emergency treatment in time to avoid life-threatening. Frequent shock is caused by the following:

1. It may be caused by a serious infection. When a serious infection occurs, failure to take anti-infection in time will lead to serious discomfort symptoms in the human body, so there will also be frequent shock.

Second, when a severe allergy occurs, it can also lead to frequent shock symptoms. If there is a severe allergy, it is necessary to take anti-allergy** in time. It is also necessary to take protective measures at ordinary times to avoid contact with food and items that are prone to allergies.

3. It is also possible that there has been a serious trauma or burns. After severe traumatic burns, the person will lose fluids and will also show signs of shock.

Frequent shock? Do you often get dizzy?

Shock is a systemic critical pathological process in which various strong hormones act on the body, causing a sharp decline in circulatory function, serious insufficiency of microcirculation perfusion in tissues and organs, and serious disorders of the function and metabolism of important vital organs.

Classified according to ** (7 types): hemorrhagic, burn, traumatic, infectious, allergic, cardiac, neurogenic

Haven't heard of transient shock.

Low blood pressure, I used to too, I used to squat down near the mound and talk to people, and after a long time I stood up, and suddenly it was dark in front of my eyes, and I fainted, and then I quickly recovered again. In fact, it is caused by low blood pressure, when squatting, the heart does not need a lot of load to supply blood to the brain, and when standing suddenly, the heart can not adapt immediately, which causes insufficient blood supply to the brain, and in severe cases, it can temporarily go into shock!Need to pay attention!

The remedy is: increase physical activity, eat more nutritious things, and get enough sleep! I believe it will be fine soon, mine will be fine!

Low blood pressure or low blood sugar.

You didn't even eat breakfast.

It is recommended that you get your blood pressure and blood sugar checked.

It's best to eat breakfast and don't sit down or squat suddenly.

The causes of shock are complex, but from the perspective of its occurrence and development, it is mainly caused by a sharp decrease in the effective circulating blood volume, which makes the blood perfusion of important tissues and organs insufficient.

1) Decreased blood volume throughout the body.

All kinds of acute blood loss, extensive burns, sweating, severe diarrhea, etc., will directly or indirectly cause a decrease in the total amount of blood.

2) Decreased cardiac output.

When acute heart failure, myocarditis, myocardial infarction, hydropericardium and other heart diseases occur, it can cause incomplete cardiac function to compensate, myocardial contractility is weakened, diastolic is limited or diastolic period is shortened, and blood cardiac output can be reduced.

3) Increased vascular volume.

Due to some factors (trauma, allergies, poisoning, etc.), the closed arterioles, veins and microcapillaries are widely dilated, and the blood volume of the blood vessels increases, although the total body blood volume does not decrease, but due to the stagnation of part of the blood in the dilated microvessels, the amount of blood returning to the heart is reduced, the output of cardiac blood is reduced, and the effective circulating blood volume of the whole body is reduced, causing shock.

Hello landlord.

Early symptoms of shock are as follows:

In the case of primary symptoms and signs, there are mild signs of excitement, such as consciousness is still clear, but irritability and anxiety, nervousness, paleness, mild cyanosis of the lips and nails, increased heart rate, increased respiratory rate, cold sweat, rapid pulse, blood pressure can drop suddenly, or slightly, or even normal or slightly high, pulse compression is small, and urine output is reduced.

Symptoms in the middle stages of shock are as follows:

Patients are irritable, unconscious, superficial breathing, decreased temperature in the extremities, muffled heart sounds, thin and weak pulses, progressively low blood pressure that may be less than 50 mm Hg or undetectable, pulse pressure less than 20 mm Hg, clammy and cold hair, little or no urine [6].

Symptoms of late shock are as follows:

Presents with DIC and multi-organ failure.

1) DIC manifestations: refractory hypotension, cyanosis or extensive bleeding, nail bed microcirculation congestion, poor efficacy of vasoactive drugs, often coexisting with organ failure.

2) Manifestations of acute respiratory failure: progressive dyspnea that is difficult to correct with oxygen, progressive hypoxemia, shortness of breath, cyanosis, pulmonary edema and decreased lung compliance.

3) Manifestations of acute heart failure: shortness of breath, cyanosis, increased heart rate, low and dull heart sounds, galloping rhythm, arrhythmia. If there is a slow heart rate, a dull complexion, and cold extremities, it is also a sign of heart failure, and the central venous pressure and the pulse pulmonary artery wedge pressure are elevated, and in severe cases, pulmonary edema may be manifested.

4) Manifestations of acute renal failure: oliguria or anuria, azotemia, hyperkalemia and other water-electrolyte and acid-base balance disorders.

5) Other manifestations: The degree of consciousness impairment reflects the cerebral blood supply. Jaundice occurs in the liver failure department, blood bilirubin increases, and the incidence of hepatic encephalopathy is not high due to the strong compensatory function of the liver.

Gastrointestinal disorders often manifest as abdominal pain, dyspepsia, hematemesis, and melena.

What does shock mean? What is the shock index?

Clinical manifestations of shock include pallor, decreased blood pressure, irritability, cold sweats, and coma. Factors such as massive blood loss, severe diarrhea, extensive burns, poisoning, fatal arrhythmias, etc., can cause shock in a person.

Shock is an acute circulatory failure caused by a variety of strong causes of ** on the body, characterized by microcirculation disorders, insufficient perfusion of important organs and cell function and metabolism disorders, the clinical manifestations of shock are blood pressure drop, systolic blood pressure less than 90mmHg, pulse velocity: both weak pulse, and increased frequency, clammy limbs, ** pale mucosa.
