Sciatica is a medical condition characterized by pain going down the leg from the lower back.[1] This pain may go down the back, outside, or front of the leg. Typically, symptoms are only on one side of the body. Certain causes, however, may result in pain on both sides.
respiratory quotient (RQ) the ratio of the volume of expired carbon dioxide to the volume of oxygen absorbed by the lungs per unit of time. Called also respiratory exchange ratio (above).
The ratio is determined by comparing exhaled gasses to room air. Measuring this ratio can be used for estimating the respiratory quotient (RQ), an indicator of which fuel (carbohydrate or fat) is being metabolized to supply the body with energy.This estimation is only valid if metabolism is in a steady state. RER is about 0.8 at rest with a modern diet.May 2007). The respiratory exchange ratio (RER) is the ratio between the amount of oxygen (O 2) consumed and carbon dioxide (CO 2) produced in one breath. Humans typically inhale more molecules of oxygen than they exhale of carbon dioxide.
