FP-C Equations & Formulas QUESTIONS AND CORRECT ANSWERS GRADED A+ PO2 given barometric pressure - Answer O2 Concentration (0.21) x Barometric pressure Sea level=760 torr 0.21 x 760 = 159 torr 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?) - Answer (%FiO2 x Current barometric pressure) / New barometric pressure 10,000-20,000 feet: (0.3 x 523) / 349 = 0.44 (New FiO2) Potential PO2 - Answer FiO2 x 5 = Potential FiO2 0.21 x 5 = 105 (Normal) PaO2/FiO2 Ratio - Answer Ratio of arterial oxygen partial pressure to fractional inspired oxygen Used to distinguish ARDS severity Pediatric ETT size - Answer (16+age) / 4 ETT depth - Answer 3x tube size Suction/NG/Foley size - Answer 2x ETT size Chest tube size - Answer 4x ETT size Fluid Resuscitation-Neonate - Answer 10mL/Kg Fluid Resuscitation-Pediatric - Answer 20mL/Kg Fluid Resuscitation-Adult - Answer 30mL/Kg Fluid Mainenance-Pediatric - Answer 4-2-1 rule 1-10 kg --> 4mL/Kg (For the first 10kg) 2-20 kg --> 2mL/Kg (For the second 10kg) >20 kg --> 1mL/Kg (For every Kg above 20)
