Читать книгу Respiratory Medicine - Stephen J. Bourke - Страница 28

During steady‐state conditions, the relationship between the amount of carbon dioxide produced by the body and the amount of oxygen absorbed depends upon the metabolic activity of the body. This is referred to as the ‘respiratory quotient’ (RQ).

The actual value varies from 0.7 during pure fat metabolism to 1.0 during pure carbohydrate metabolism. The RQ is usually about 0.8, and it is assumed to be such for everyday clinical calculations.
