RPE = or > 18. /Creator A 52-year-old female patient has been smoking 1.5 packs of cigarettes per day for 30 years. 660 L of o2 in a full tank at 2200 psi, so 660/2200 = x/psi showing. Note that this calcuation provides you with an estimate only and the actual consumption may be higher. 33. Firstly, you should find an appropriate location to walk precisely 1 mile (1609 meters). Maybe try searching? Please note that the VAE Calculator will not ask you to enter any patient identifiers (other than dates of mechanical ventilation, which you can change as you see fit). O2 consumption = VO2 = QT x (CaO2 CvO2). Most of our vents have the Bias Flow set at 5 LPM FiO2 Oxygen consumption will vary depending on set FiO2 At 100%, the total volume is supplied from the Oxygen tank. If the value of (By) is higher, the total consumption value will increase. Uniform mixing of LN or CO2 with room air. 2,3. N Engl J Med .
