What is the relationship between pressure and resistance?

What is the relationship between pressure and resistance?

In the arterial system, as resistance increases, blood pressure increases and flow decreases. In the venous system, constriction increases blood pressure as it does in arteries; the increasing pressure helps to return blood to the heart.

In which position is blood pressure normally highest?

What is the difference between hypotension and hypertension?

Hypotension is the opposite of hypertension, which is high blood pressure. It is best understood as a physiological state rather than a disease. Severely low blood pressure can deprive the brain and other vital organs of oxygen and nutrients, leading to a life-threatening condition called shock.

What are the symptoms of BP high and low?

If you do get symptoms, they may be identified as any of the following:

• Feeling dizzy, light headed or fainting.
• Blurred vision.
• A rapid or irregular heartbeat.
• Feeling nauseous.
• Confusion.

Why do we give fluids for hypotension?

Hypotensive resuscitation consists of a restrictive approach to the administration of IV fluids and blood with the goal of keeping mean arterial pressures (MAP) high enough for essential organ perfusion but lower than normal in order to limit bleeding.

What is the best medicine for low BP?

The following drugs are often used in treating low blood pressure.

• Fludrocortisone. Fludrocortisone is a medication that seems to help most types of low blood pressure.
• Midodrine. Midodrine activates receptors on the smallest arteries and veins to produce an increase in blood pressure.

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.
