Airway: Establish and maintain patent airway
Respiration: Decompress suspected tension pneumothorax, seal open chest
wounds, and support ventilation and oxygenation as required.
Circulation: Provide vascular access (IV/IO) and administer fluids as required to
treat shock
Head injury/Hypothermia: Prevent or treat hypotension and hypoxia to prevent
worsening of TBI and prevent or treat hypothermia.
AVPU - CORRECT ANSWER -Assessing Alertness
A: Alert and oriented
V: Responds to verbal stimuli
P: Responds only to painful stimuli
U: Unresponsive

-Preoxygenation: high flow oxygen for minimum of 3 minutes. Position is HOB
elevated to 20 degrees. For spinal precautions, reverse Trendelenburg at 30
degrees.
-Pre-intubation optimization: Lidocaine (may reduce risk of rise in ICP during
intubation) or Fentanyl (mitigates sympathetic response increased HR and BP
during intubation) administration
-Paralysis with induction
-Protection: after neuromuscular blocking agent is administered, protect the airway
from aspiration by avoiding BVM, which can result in regurgitation and aspiration.
-Placement with proof: inflate ETT cuff, secure, use ETCO2 for confirmation
-Post-intubation management: secure tube and note measurement; xr.

The pressure of the CSF in the subarachnoid space
Mean Arterial Pressure (MAP) - CORRECT ANSWER -50-150mmHg
The average blood pressure in a single cardiac cycle, roughly calculated as the SBP
+ 2 x the DBP/3
Avoid hypoxemia in the patient with head trauma - CORRECT ANSWER -A single
episode of hypoxemia (PaO2 <60mmHg) can be detrimental to the patient's outcome.
Maintain pulse ox at 95% or greater and obtain ABG measurement asap for patient
with severe TBI.
Maintain ETCO2 between 35-45 mmHg
