A flow rate of 2 liters per minute increases the FiO2 from 21 percent (room air) to 28 percent. It is the maximum volume of oxygen that your body is capable of consuming and converting to energy for your working muscles. To determine your VO2 max if your resting heart rate is 60 bpm and you're 30 years old: Calculate your maximum heart rate by multiplying your age by 0.7 and deducting it from 208, which equals 187 bpm. Inspired O2 (PiO2) PiO2 = FiO2 x (barometric pressure - saturated vapour pressure of H20) PiO2 = 0.21 x (760 - 47) - sea level. (must have javascript enabled). The amount of reactant lost or product gained can be measured by recording the mass in grams (for solids) or the volume in cm 3 (for liquids). Maybe try searching? These methods are based on the following: Each of the methods is explained in detail in the section below. Therefore the calculation would be: VO2 = Chminute volume * (ChO2 - O2inspired) / 100 Then just. A 52-year-old female patient has been smoking 1.5 packs of cigarettes per day for 30 years.
