The doctor has requested the static compliance measurement for an adult patient who is receiving mechanical ventilation. How do you calculate ventilation in liters per minute? Ventilation rate is expressed as the volume of gas entering or leaving the lungs in a given amount of time. Moreover, it is a good predictor of your potential as an endurance athlete or even an indicator of future health. 9 0 obj 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).

Inspired O2 (PiO2) PiO2 = FiO2 x (barometric pressure - saturated vapour pressure of H20) PiO2 = 0.21 x (760 - 47) - sea level. Oxygen consumption (VO 2) is the amount of oxygen taken in and used by the body per minute; thus, it is the rate of oxygen use. Oxygen Consumption (VO2) VO2 = Cardiac Output x C (a-v)O2 Oxygen Extraction Ratio (O2ER) O2ER = (CaO2 - CvO2) / CaO2 FiO2 Estimation for Nasal Cannula FiO2 = 20 + (4 x Liter Flow) Oxygen Cylinder Duration Duration = (Gauge Pressure x Tank Factor) / Liter Flow Liquid Oxygen System Duration Duration = (344 x Liquid Weight) / Flow Cardiac Index (CI) In order to better solve the phenomenon of low oxygen in the corner of return airway caused by abnormal gas emission in goaf during shallow coal seam mining, by analyzing the source and reason of low oxygen phenomenon, a prediction model of oxygen concentration in the corner of return airway based on genetic algorithm (GA) and random forest (RF) technology was proposed. Normal ventilation leads to high (or normal) CO2 in the arterial blood and body cells. Maybe try searching?
