Hello Guys Welcome to this my blog today I am going to write a some answer What pressure is considered lethal If, when measuring blood pressure, the tonometer regularly shows a pressure of 140/90 mmHg. Art. and above, then the person is at risk of premature death. But both high blood pressure and low blood pressure have dismal prognoses for patient survival.
It is believed that normal blood pressure for a person is 120/80 or less. Anything 140/90 or higher is pathological.
What is a hypertensive crisis and why is it dangerous?
Untreated hypertension can lead to a hypertensive crisis. A hypertensive crisis is a sharp increase in pressure in the blood vessels to 180/120 mmHg. Art. and higher. It can lead to heart attack, stroke, or damage to other internal organs such as the kidneys.
In a hypertensive crisis, the aorta, which distributes blood from the heart throughout the body, can also rupture. This condition is called aortic dissection. An artery supplying blood to the brain may also rupture, causing a hemorrhagic stroke.
If a person with a blood pressure of 180/120 mm Hg. Art. and above, severe headache, speech problems, nausea and convulsions, nosebleeds or shortness of breath occur, you should immediately call an emergency ambulance.
What low blood pressure is considered fatal?
A blood pressure of 90 to 60 millimeters of mercury or lower is considered dangerous. If a person encounters such indicators for the first time, it is necessary to call a doctor. However, due to the nature of the autonomic nervous system, low blood pressure may be normal for some people.
Dangerous symptoms of hypotension occur in combination with cold sweat, chest pain, shortness of breath and tachycardia, and in some cases, loss of consciousness.
When low pressure persists for a long time, the efficiency of blood circulation deteriorates; internal organs do not receive enough oxygen, which affects their work and human well-being.
