medical health lung and respiratory healthWhat is the similarity and difference between RER and RQ?
Last Updated: 8th March, 2020
1. Respiratory quotient (RQ) is the proportion of CO2 volume generated to the O2 volume consumption at cellular levels. 2. Respiratory exchange ratio (RER) is the proportion of CO2 volume generated to the O2 volume consumption by using expelled air in the calculation.

In this way, what is the difference between RER and RQ?
RQ and RER are two different scientific methods of measuring the type of metabolic fuel the body is using to produce energy. RQ is a direct measurement taken from the blood and RER in an indirect measurement taken through the breath. RQ is the ratio of CO2 production (Vco2) and O2 consumption (Vo2) in the tissues.
Furthermore, what is an RQ value? Definition. The respiratory quotient (RQ) is the ratio of CO2 produced to O2 consumed while food is being metabolized: RQ = CO2 eliminated/O2 consumed. Most energy sources are food containing carbon, hydrogen, and oxygen. Examples include fat, carbohydrates, protein, and ethanol.
what does an RER of 1.00 indicate?
The respiratory exchange ratio (RER) is the ratio between the amount of carbon dioxide (CO2) produced in metabolism and oxygen (O2) used. A value above 1.0 cannot be attributed to the substrate metabolism, but rather to the aforementioned factors regarding bicarbonate buffering.
What does a high RER mean?
A high RER indicates that carbohydrates are being predominantly used, whereas a low RER suggests lipid oxidation (Simonson and DeFronzo, 1990; Pendergast et al.
