what is parkland formula
4 cc PLR x kg x %BSA burned
half is given over the 1st 8 hours
remaining is given over the next 16 hours
Patients with GCS score of ___ require aggresive management, generally including stabilization of the airway and breathing with endotracheal intubation and mech vent
GCS <8
If patient has no pulse and breathing, what is the ratio of breathing and compression if 1 or 2 rescuer
1 rescuer: 30 compressions - 2 breaths
2 rescuer: 15 compressions - 2 breaths
If patieht has no normal breathing and has pulse, how do you provide rescue breathing
Old guidelines: 1 breath every 3-5 seconds or about 12-20 breaths/min
2020 guidelines: 1 breath every 2-3 seconds or 20-30 breaths/min
Medications to be given if bradycardia is persistent after CPR
Epinephrine (0.01 mg/kg or 0.1 mL/kg of 1:10,000 concentration) or Atropine (0.02 mg/kg, max dose 0.5 mg)

infants: liquids
toddlers and older children: small objects and food
Dose of synchronized cardioversion done in SVT

Once advanced airway is established during cardiac arrest, how many breaths are given?
Old guidelines: 1 breath every 6-8 seconds or 8-12 breaths per minute
2020 guidelines: 1 breath every 2-3 seconds or 20-30 breaths per minute
