Question

You have a patient with a very low blood pressure of 80/60 mm hg. What are the possible consequences of this low blood pressure on capillary function?

Answer 1

Low blood pressure means that their is less force on the capillary walls and and therefore less gaseous exchange. This can cause cold extremities.

Low blood pressure causes drowsiness. And in some cases, serious brain damage. As brain is deprived of oxygen and brain tissues can barely survive for 4-5 seconds without the oxygen.
