Respiratory Quotient (Rq)

Respiratory Quotient (Rq) is the ratio of the volume of carbon dioxide entering the alveoli of the lungs from the blood to the volume of oxygen absorbed by the alveoli. This coefficient shows what proportion of the oxygen consumed is used for the oxidation of organic substances, and what part is used for the oxidation of inorganic compounds.

Usually the respiratory coefficient is about 0.8, since compared to the carbon dioxide released, most of the oxygen is consumed. This is due to the fact that the main source of energy for the body is organic substances - proteins, fats and carbohydrates. When they oxidize, carbon dioxide and water are formed.

Thus, the value of the respiratory coefficient reflects the relationship between the oxidation of organic and inorganic substances in the body. Its changes may indicate metabolic disorders.



Respiratory Quotient (Rq) is one of the most important indicators characterizing the process of gas exchange between the body and the environment. It reflects the ratio of the volume of carbon dioxide (CO2) moving from the blood into the lungs to the volume of oxygen (O2) consumed.

The respiratory coefficient plays an important role in maintaining homeostasis in the body. It allows you to regulate the acid-base balance (pH), which is an important indicator of health. A high respiratory quotient indicates elevated levels of CO2 in the blood, which can lead to diseases such as asthma and other respiratory diseases.

Typically the respiratory coefficient is 0.8. This means that for every volume of O2 consumed, the body emits approximately 0.8 volumes of CO2. However, this indicator may vary depending on various factors such as physical activity, nutrition, age, etc.

It is important to note that imbalance between CO2 and O2 can lead to serious health consequences. For example, high CO2 levels can cause hypoxia (lack of oxygen) and lead to various diseases such as cardiovascular diseases, diabetes, etc. Therefore, maintaining a normal respiratory quotient is an important task for maintaining human health and well-being.



The respiration coefficient (respiratory quotient - Rq) is an indicator of the body's breathing efficiency. Rq is the ratio of the volume of carbon dioxide exhaled to the volume of oxygen inhaled, usually denoted by the letter Q and represents the volume of gases that pass through the lungs per unit time, hence the name "ratio". The RQ value is either a fraction of one (usually around 0.7–0.9) or a ratio (quantitative expression). The body's normal respiratory activity is called aerobic or aerobic metabolism, which means the body uses oxygen to produce energy for its functioning, usually excreted through respiration and urine. When there is not enough O2 in the body, breathing capacity is reduced and can lead to serious health problems such as hypoxia (lack of oxygen in the body's tissues).

In conclusion, we can say that the respiratory quotient is used to determine the state of health of the body in people leading an active lifestyle and engaging in physical exercise, especially high-intensity exercise. Strength training with heavy weights can cause decreased breathing



“Respiratory coefficient” is one of the most important characteristics of respiration in living organisms. It reflects the balance between oxygen supply and carbon dioxide production in the body. This coefficient is an important indicator of the functioning of the lungs and their ability to saturate with oxygen.

So, to begin with, the respiratory quotient determines the amount of carbon dioxide CO2 released, as well as its consumption. This is an important criterion for assessing the overall functioning of the respiratory system in humans and animals. The respiratory quotient can help in diagnosing various disorders in the respiratory system, such as Alzheimer's disease, bronchial asthma, lung cancer, etc. Changes in breathing may be associated with insufficient intake or excess CO2 release. In this case, it is necessary to take measures to normalize the supply of oxygen to the body. Unfortunately, in the modern world the problem of environmental pollution is becoming more and more acute. Toxic emissions from industrial enterprises, vehicle exhaust gases and other sources of pollution have a negative impact on the environment and the health of residents of nearby areas. It is important to take measures to improve the environmental situation. For example, the use of environmentally friendly transport, green
