What flow rate would be necessary to deliver a tidal volume of 600 mL with a constant waveform at a respiratory rate of 15/min with an I:E ratio of 1:4? Oxygen Consumption (VO 2) VO 2 = Cardiac Output x C(a-v)O 2 Oxygen Extraction Ratio (O 2ER) O 2ER = (CaO 2 - CvO 2) / CaO 2 FiO . Keep practicing, I know you can do it! Normal ventilation leads to high (or normal) CO2 in the arterial blood and body cells. Three different tidal volumes (Vt) were tested (500, 750, and 1000 mL) with HC and LC lung models, and the fresh gas flow rate was 1 L/min. Y'all are assuming E-cylinders for your estimate of PSI/3. 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.
