The co₂ breathing emission calculator is a powerful tool designed to estimate the amount of carbon dioxide an individual exhales through respiration.
This calculator considers various factors such as metabolic rate, activity level, and body mass to provide an approximation of a person’s CO₂ output through breathing.
The CO₂ Breathing Emission Calculator might take inputs like:
- Weight: 70 kg
- Age: 30 years
- Gender: Female
- Activity level: Moderately active
CO₂ Breathing Emission Calculator
| Gender | Age | Weight (kg) | Height (cm) | Activity Level | CO₂ Emission (L/day) |
|---|---|---|---|---|---|
| Male | 25 | 75 | 180 | Very active | 571.23 |
| Female | 40 | 60 | 160 | Lightly active | 266.45 |
| Male | 55 | 85 | 175 | Sedentary | 314.78 |
| Female | 30 | 70 | 170 | Moderately active | 389.12 |
| Male | 35 | 80 | 185 | Extra active | 689.56 |
CO₂ Breathing Emission Calculation Formula
CO₂ produced = O₂ consumed * Respiratory Quotient (RQ)Where:
- O₂ consumed is measured in liters per day
- RQ is the ratio of CO₂ produced to O₂ consumed (typically around 0.8 for a mixed diet)
To calculate O₂ consumption, we first need to estimate the Basal Metabolic Rate (BMR) using the Harris-Benedict equation:
For men:
BMR = 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) - (5.677 * age in years)For women:
BMR = 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) - (4.330 * age in years)The BMR is then multiplied by an activity factor:
- Sedentary: BMR * 1.2
- Lightly active: BMR * 1.375
- Moderately active: BMR * 1.55
- Very active: BMR * 1.725
- Extra active: BMR * 1.9
This gives us the Total Energy Expenditure (TEE) in calories per day.
To convert TEE to O₂ consumption:
O₂ consumed (L/day) = TEE * 0.21Finally, to calculate CO₂ production:
CO₂ produced (L/day) = O₂ consumed * 0.8 (RQ)How to Calculate CO₂ Breathing Emission?
Let’s walk through an example calculation:
- Input data:
- Gender: Female
- Age: 30 years
- Weight: 65 kg
- Height: 165 cm
- Activity level: Moderately active
- Calculate BMR: BMR = 447.593 + (9.247 * 65) + (3.098 * 165) – (4.330 * 30) BMR = 1,385.87 calories/day
- Calculate TEE: TEE = 1,385.87 * 1.55 (moderately active) TEE = 2,148.10 calories/day
- Calculate O₂ consumption: O₂ consumed = 2,148.10 * 0.21 O₂ consumed = 451.10 L/day
- Calculate CO₂ production: CO₂ produced = 451.10 * 0.8 CO₂ produced = 360.88 L/day
This person would exhale approximately 360.88 liters of CO₂ per day through breathing.
How Much CO₂ Do You Exhale Per Day?
On average, an adult at rest exhales about 400 liters of CO₂ per day.
- Body size: Larger individuals generally produce more CO₂.
- Metabolic rate: Higher metabolism leads to increased CO₂ production.
- Physical activity: Exercise significantly increases CO₂ output.
- Diet: The type and amount of food consumed affects CO₂ production.
- Environmental conditions: Temperature and altitude can influence respiration rates.
A professional athlete during intense training might produce up to 2,000 liters of CO₂ per day, while a sedentary individual might only produce 300 liters.
