FP-C Equations & Formulas
PO2 given barometric pressure correct 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?) correct 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 correct answer: FiO2 x 5 = Potential FiO2
0.21 x 5 = 105 (Normal)
PaO2/FiO2 Ratio correct answer: Ratio of arterial oxygen partial pressure to fractional inspired oxygen
Used to distinguish ARDS severity
Pediatric ETT size correct answer: (16+age) / 4
ETT depth correct answer: 3x tube size
Suction/NG/Foley size correct answer: 2x ETT size Chest tube size correct answer: 4x ETT size
Fluid Resuscitation-Neonate correct answer: 10mL/Kg
Fluid Resuscitation-Pediatric correct answer: 20mL/Kg
Fluid Resuscitation-Adult correct answer: 30mL/Kg
Fluid Mainenance-Pediatric correct 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)
So, for a 30 kg child, maintenance fluid rate would be:
40 ml/hr + 20 ml/hr + 10 ml/hr = 70 ml/hr
Blood administration-Universal donor correct answer: O Negative
Blood administration-Universal recipient correct answer: AB
Parkland burn formula correct answer: 4mL x weight in kg x TBSA burned
1/2 in the first 8 hours
1/2 in the next 16 hours
