Respiratory quotient is the ratio of the volume of carbon dioxide released to the volume of oxygen absorbed by an organism, cell or tissue over a given period of time. (Respiratory Quotient). Volume of Co2 produced/Volume of O2 consumed = Respiratory Quotient. Essentially, respiratory quotient is a measurement to show how well your body burns fats. It is measured during a resting metabolic rate assessment or calorie point. When you measure how much oxygen is inhaled and how much carbon dioxide is exhaled, the amount of carbohydrates and fat being burned can be measured. Our bodies are only able to use fat as a major fuel source when it’s able to get O2 into the cells. A person’s resting or moderately active respiratory quotient should be 0.7 to 1.0. When we do intense workouts our ratio increases about 1.0, thus making our bodies work anaerobically (this means without O2). When your R.Q. is high that means our bodies are burning more carbohydrates and less fat. In turn, if you are trying to lose weight and it’s not coming off it could be because your R.Q. is too high. Proper exercise and diet can help you decrease your R.Q. (Nikkola, 2010). R.Q. is a method that was developed to help a person target which substrate of energy they are using, whether it is carbohydrates, proteins, or fats. It is useful in determining fat catabolism and ATP expenditure because the amount of the O2 used will be different for fat versus other macronutrients. Fat has a lower value than other macronutrients since fatty acids require O2 for catabolism. (Kent, 2011). In the case of COPD patients, proper nutrition can help reduce carbon dioxide levels and improve breathing. It is important to focus on the percentages of total carbohydrates, fats, and proteins that the patient is consuming to see how their diet composition impacts their R.Q. Basically that means, following metabolism, in
