If we want to calculate the ATPS, and were given for example that the total volume of expired air (L) was 30.6 L provided that the air was collected over an interval of 3-minutes, will ATPS in this case be: 30.6 L / 3 min = 10.2 ?
If we have the following values:
- Number of breaths in one-minute = 16
- Exhaled minute volume ATPS (L min-1) = 5.50
Will the tidal volume ATPS (L) be ---> 5.50 / 16 = 0.34 ?
If we were given the following values:
- Oxygen concentration of expired air = 16.7%
- Exhaled minute volume ATPS (L min-1) = 5.67
And, want to calculate the "Oxygen exhalation rate ATPS (ml min-1)", would it be as follows?
5.67 X 16.7% = 0.95
But, since the value has to be in (ml min-1), we should multiply by 1000, so, the final result will be 950 ml min-1
Is it correct this way?
