As a medical professional with expertise in cardiovascular health, I can provide you with information on dangerously low blood pressure, which is also known as hypotension.
Blood pressure is typically measured in millimeters of mercury (mmHg) and is expressed as two numbers, with the top number representing systolic pressure (the pressure when the heart beats) and the bottom number representing diastolic pressure (the pressure when the heart is at rest). Normal blood pressure is generally considered to be around 120/80 mmHg.
Dangerously low blood pressure can occur when the systolic pressure falls below 90 mmHg or the diastolic pressure falls below 60 mmHg. However, it's important to note that what is considered "dangerously low" can vary from person to person, and it depends on the individual's baseline blood pressure and overall health condition. For some people, particularly the elderly or those with chronically low blood pressure, a reading of 90/60 mmHg might be normal.
Symptoms of low blood pressure can include dizziness, lightheadedness, fainting, blurred vision, and fatigue. It can be caused by various factors such as dehydration, certain medications, heart problems, or prolonged bed rest.
When blood pressure drops to a level that is not sufficient to maintain adequate blood flow and oxygen supply to the body's organs, it becomes a medical emergency. This is known as orthostatic hypotension, where the drop in blood pressure occurs when a person stands up from a sitting or lying position.
Treatment for dangerously low blood pressure depends on the cause and the severity of the symptoms. It may involve lifestyle changes, adjusting medications, or in severe cases, hospitalization for intravenous fluids or medications.

Hypotension is the medical term for low blood pressure (less than 90/60). A blood pressure reading appears as two numbers. The first and higher of the two is a measure of systolic pressure, or the pressure in the arteries when the heart beats and fills them with blood.
