In order to work out the total amount of oxygen required under these changed circumstances, it is necessary to know how to calculate the oxygen consumption for a particular ventilator. Maybe try searching? It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time. /Annots [] Minute Ventilation (VE)VE = Respiratory Rate x Tidal Volume, Alveolar Minute Ventilation (VA)VA = Respiratory Rate x (Tidal Volume Deadspace), Airway Resistance (Raw)Raw = (PIP Plateau pressure) / Flow, Mean Airway Pressure (Paw)Paw = ((Inspiratory Time x Frequency) / 60) x (PIP PEEP) + PEEP, Work of Breathing (WOB)WOB = Change in Pressure x Change in Volume, Alveolar-Arterial Oxygen Tension Gradient (P(A-a)O2)P(A-a)O2 = PAO2 PaO2, Alveolar Oxygen Tension (PAO2)PAO2 = (PB PH2O) x FiO2 (PaCO2 / 0.8), Arterial/Alveolar Oxygen Tension (a/A) Ratio(a/A) Ratio = PaO2/PAO2, Arterial Oxygen Content (CaO2)CaO2 = (Hb x 1.34 x SaO2) + (PaO2 x 0.003), End-Capillary Oxygen Content (CcO2)CcO2 = (Hb x 1.34 x SaO2) + (PAO2 x 0.003), Mixed Venous Oxygen Content (CvO2)CvO2 = (Hb x 1.34 x SvO2) + (PvO2 x 0.003), Shunt Equation (QS/QT)QS/QT = (CcO2 CaO2) / (CcO2 CvO2), Modified Shunt Equation (QS/QT)QS/QT = ((PAO2 PaO2) x 0.003) / ((CaO2 CvO2) + (PAO2 PaO2) x 0.003), Arterial-Mixed Venous Oxygen Content Difference (C(a-v)O2)C(a-v)O2 = CaO2 CvO2, Oxygen-to-Air Entrainment Ratio (O2:Air)O2:Air = 1 : (100 FiO2) / (FiO2 2), Arterial Oxygen Saturation Estimation (SaO2)SaO2 = PaO2 + 30, PaO2/FiO2 Ratio (P/F Ratio)P/F Ratio = PaO2 / FiO2, Oxygenation Index (OI)OI = ((Paw x FiO2) / PaO2) x 100, Oxygen Consumption (VO2)VO2 = Cardiac Output x C(a-v)O2, Oxygen Extraction Ratio (O2ER)O2ER = (CaO2 CvO2) / CaO2, FiO2 Estimation for Nasal CannulaFiO2 = 20 + (4 x Liter Flow), Oxygen Cylinder DurationDuration = (Gauge Pressure x Tank Factor) / Liter Flow, Liquid Oxygen System DurationDuration = (344 x Liquid Weight) / Flow, Cardiac Index (CI)CI = Cardiac Output / Body Surface Area, Cardiac Output (QT)QT = Heart Rate x Stroke Volume, Cardiac Output (CO) Ficks MethodCO = (O2 Consumption / CaO2 CvO2), Cerebral Perfusion Pressure (CPP)CPP = Mean Arterial Pressure Intracranial Pressure, Mean Arterial Pressure (MAP)MAP = (Systolic BP + (2 x Diastolic BP)) / 3, Stroke Volume (SV)SV = Cardiac Output / Heart Rate, Maximum Heart Rate (HRmax)HRmax = 220 Age, Heart Rate on an EKG Strip (HR) HR = 300 / # of large boxes between R waves, Systemic Vascular Resistance (SVR)SVR = (MAP CVP) x (80 / Cardiac Output), Pulmonary Vascular Resistance (PVR)PVR = (MPAP PCWP) x (80 / Cardiac Output), Static Compliance (Cst)Cst = Tidal Volume / (Plateau Pressure PEEP), Dynamic Compliance (Cdyn)Cdyn = Tidal Volume / (Peak Pressure PEEP), Deadspace to Tidal Volume Ratio (VD/VT)(VD/VT) = (PaCO2 PECO2) / PaCO2, Children Dosage EstimationChild Dose = (Age / Age + 12) x Adult Dose, Infant Dosage EstimationInfant Dose = (Body Weight in lbs / 150) x Adult Dose, Infant and Children Dosage Estimation (Frieds Rule)Infant or Child Dose = (Age in Months / 150) x Adult Dose, Body Surface Area (BSA)BSA = ((4 x Body Weight) + 7) / (Body Weight + 90), ElastanceElastance = Change in Pressure / Change in Volume, Smoking Use Calculation (Pack Years)Pack Years = (Packs Smoked per Day) x (Number of Years Smoked), Suction Catheter Size EstimationCatheter Size = (Internal Diameter / 2) x 3, Endotracheal Tube Size Estimation in ChildrenTube Size = (Age + 16) / 4, LaPlaces LawP = (2 x Surface Tension) / Radius, Celsius to Fahrenheit Temperature ConversionF = (C x 1.8) + 32, Fahrenheit to Celsius Temperature ConversionC = (F 32) / 1.8, Celsius to Kelvins Temperature ConversionK = C + 273, Helium/Oxygen Conversion (He/O2)Actual Flow = Given Flow Rate x Factor, Total Lung Capacity (TLC)TLC = IRV + VT + ERV + RVTLC = VC + RVTLC = IC + FRC, Vital Capacity (VC)VC = IRV + VT + ERVVC = IC + ERVVC = TLC RV, Inspiratory Capacity (IC)IC = IRV + VTIC = TLC FRCIC = VC ERV, Functional Residual Capacity (FRC)FRC = ERV + RVFRC = TLC IC, Time Constant (t)t = Compliance x Resistance, Ideal Body Weight (IBW)IBW = 50 kg + (2 x Number of Inches over 5 feet), Tidal Volume (VT)VT = Flow rate x Inspiratory Time, Exhaled Tidal Volume (VT)VT = Minute Ventilation / Frequency, Corrected Tidal Volume (VT)VT = Expired Tidal Volume Tube Volume, Pressure Support Ventilator Setting (PSV)PSV = ((Peak Pressure Plateau Pressure) / Set Flow) x Peak Flow, Rapid Shallow Breathing Index (RSBI)RSBI = Rate / Tidal Volume, Minimum Flow Rate in Mechanical VentilationFlow Rate = Minute Ventilation x I:E Ratio Sum of Parts, Winters FormulaExpected PaCO2 = (1.5 x HCO3-) + 8 2.

In a retrospective study of 74 ventilated neonates with severe hypoxemic respiratory failure, OSI was shown to correlate significantly with the oxygen index in that population. PiO2 = 150mmHg. Take a closer look at the VO2 max formula-based methods used for VO2 max estimation in our aerobic capacity calculator. 30.0 mL/cm H2O. 39. Particularly in low- and middle-income countries (LMICs), where supplies are likely to be inadequate in the face of the pandemic, boosting access to medical oxygen can save lives. you could disconnect your macine from the wall for 15 minutes, run it off the cylinder in back and calculate the amount of consumption based off the aforementioned loss of pressure calculations. MITs Alan , In 2020, as a response to the disruption caused by COVID-19, the College Board modified the AP exams so they were shorter, administered online, covered less material, and had a different format than previous tests.
