What happens when your blood pressure drops to 70 over 40?

However, 70/40 is a rather low reading, and could definitely cause the need to sit down or feel a little lightheaded. Unusually low readings should be evaluated to rule out medical causes such as orthostatic hypotension, endocrine disorders, fainting, dehydration, severe infection and shock.

The symptoms of shock include cold and sweaty skin that may be pale or gray, weak but rapid pulse, irritability, thirst, irregular breathing, dizziness, profuse sweating, fatigue, dilated pupils, lackluster eyes, anxiety, confusion, nausea, and reduced urine flow. If untreated, shock is usually fatal.

What are the four stages of hypovolemic shock?

There are four stages of hypovolemic shock:Loss of up to 750 cubic centimeters (cc) or milliliters (mL) of blood, up to 15% of your total volume. … Loss of 750 to 1,500 cc of blood. … Loss of 1,500 to 2,000 cc of blood, about a half-gallon. … Loss of more than 2,000 cc of blood, more than 40% of your total blood volume.Apr 30, 2020

What type of shock causes poor distribution of blood?

Distributive shock results from excessive vasodilation and the impaired distribution of blood flow. Septic shock is the most common form of distributive shock and is characterized by considerable mortality (treated, around 30%; untreated, probably >80%).

Does blood pressure increase during shock?

A narrow pulse pressure in a hypovolemic shock patient indicates a decreasing cardiac output and an increasing peripheral vascular resistance. The decreasing venous volume from blood loss and the sympathetic nervous system attempt to increase or maintain the falling blood pressure through systemic vasoconstriction.

What happens to heart rate during shock?

Patients in compensated shock will have an increase in heart rate and pale skin caused by vasoconstriction. Their blood pressure may be normal. Epinephrine also causes anxiety and sweating (diaphoresis).

What are the 3 stages of shock?

What is the lowest blood pressure that is safe?

Most doctors consider blood pressure too low only if it causes symptoms. Some experts define low blood pressure as readings lower than 90 mm Hg systolic or 60 mm Hg diastolic. If either number is below that, your pressure is lower than normal. A sudden fall in blood pressure can be dangerous.

Can you have shock without hypotension?

Unfortunately, shock may present in a variety of ways, so diagnosis isn’t always so simple. For example, shock is typically associated with hypotension and reduced cardiac output, but it can also occur with normal blood pressure and an increased cardiac output.

Does shock lower blood pressure?

If shock is suspected call 911 or get to an emergency department immediately. The main symptom of shock is low blood pressure. Other symptoms include rapid, shallow breathing; cold, clammy skin; rapid, weak pulse; dizziness, fainting, or weakness.

Why does shock cause low blood pressure?

If blood pressure drops too low, the body’s vital organs do not get enough oxygen and nutrients. When this happens, low blood pressure can lead to shock, which requires immediate medical attention. Signs of shock include cold and sweaty skin, rapid breathing, a blue skin tone, or a weak and rapid pulse.
