1. PO2 given barometric pressure: O2 Concentration (0.21) x Barometric pres- sure Sea level=760 torr 0.21 x 760 = 159 torr 2. Percentage of O2 required at higher altitudes (i.e. if my FiO2 is 0.3 at 10,000 feet, what do I need to increase my FiO2 to at 20,000?): (%FiO2 x Current barometric pressure) / New barometric pressure 10,000-20,000 feet: (0.3 x 523) / 349 = 0.44 (New FiO2) 3. Potential PO2: FiO2 x 5 = Potential FiO2 0.21 x 5 = 105 (Normal) 4. PaO2/FiO2 Ratio: Ratio of arterial ox...
