What is p02?
P02 is the partial pressure that oxygen exerts on a vein, artery or any other blood vessel.
Explain one of the reasons why a person changing quickly from a horizontal to vertical position temporarily may feel dizzy?
The reason has to do with how blood flows through the body, and blood pressure. When lying down, blood pressure to the brain is fairly low, since there is less pressure required to pump blood to the brain in a horizontal body - it's not fighting gravity as the entire body is on the same level plane. However, when a person stands up too quickly, the body doesn't have enough time to react to the rapid increase in gravity that short distance causes, and therefore doesn't have enough time to increase blood pressure flow to the brain. So the reason a person can feel dizzy is that when they stand up, there isn't enough blood flow to the brain yet - it takes a couple of seconds for the heart to catch up. It can also happen even if a person is just stiting down and stands up.
What is A math problem used by doctors?
Doctors use math daily: - measuring height and weight (percentages, ratios) - measuring blood pressure and heart rate (fractions) - measuring dosages of medications - measuring levels of blood, urine, saliva, or other samples
What is hypotense?
Hypotension is considered low blood pressure. Anything under the established 120/80 is considered hypotension, whether systolic or diastolic. Systolic is the 120 and measures the pressure of the arteries when the heart contracts and diastolic is the 80 and measures the pressure of the arteries when the heart is at rest.
Example of normal distribution?
Male and female blood pressure, IQ, SAT and other test scores, life of a light bulb, weight and height, shoe sizes... Hope this helps!
