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 oxygen partial pressure to fractional inspired oxygen Used to distinguish ARDS severity 5. Pediatric ETT size: (16+age) / 4 6. ETT depth: 3x tube size 7. Suction/NG/Foley size: 2x ETT size 8. Chest tube size: 4x ETT size 9. Fluid Resuscitation-Neonate: 10mL/Kg 10. Fluid Resuscitation-Pediatric: 20mL/Kg 11. Fluid Resuscitation-Adult: 30mL/Kg 12. Fluid Mainenance-Pediatric: 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) So, for a 30 kg child, maintenance fluid rate would be: 40 ml/hr + 20 ml/hr + 10 ml/hr = 70 ml/hr 13. Blood administration-Universal donor: O Negative 14. Blood administration-Universal recipient: AB 15. Parkland burn formula: 4mL x weight in kg x TBSA burned 1/2 in the first 8 hours
