The basic concept is, as oxygen from the air in the respirometer will be consumed in the reaction; the volume of the oxygen gas decreases, and the pressure decreases as well. QxCF Numerous studies reveal that high-intensity interval training (HIIT) workouts are associated with increased VO2 max. 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. The Oxigraf Oxygen/CO2 Analyzers respond in less than a second.. While setting up a new patient on the ventilator, the plateau pressure is 47 cmH2O, and the tidal volume is set at 100 mL. Predicts outcomes, especially in pediatric patients; helps determine need for ECMO.
