It's Shocking
A blood loss of 15-30% is this class of hemorrhagic shock
Class II
This is the normal range of ICP
4-15
Touch cheek and upper lip will twitch with low calcium
Chvostek's Sign
Cerebral Perfusion Pressure formula
MAP - ICP (Range: 60-70)
Caused by large amount of injured muscle releasing myoglobin in the blood and then filtered through the kidneys
Rhabdomyolysis
Neurogenic, septic, and anaphylactic are all types of this shock
Distributive shock
This cranial nerve is responsible for vision and visual fields
CN II (Optic)
Inflate BP cuff to elicit carpopedal spasm
Trousseau's Sign
Mean Arterial Pressure Formula
SBP + 2(DBP) / 3 (Range: 70-100)
This is the normal amount of compartmental pressure in the extremity
10mmHg
Trauma induced coagulopathy is defined with an INR greater than this number
1.5
Increased SBP, widening pulse pressure, and bradycardia Triad indicating increased ICP
Cushing's Triad
Ecchymosis around the flanks
Grey-Turner's Sign
Cardiac Output Formula
HR x SV (Range 4-8)
Most common fracture due to a fall on an outstretched arm
Scaphoid fx
These fluids are used for volume expansion
Colloids
Neuro condition that causes ipsilateral motor paralysis and contralateral loss of pain and temperature
Brown-Sequard Syndrome
Ecchymosis around the umbilicus
Cullen's Sign
Pulse Pressure Formula
SBP - DBP (range: 30-50)
Most common compartment of the lower leg that develops compartment syndrome
Anterior compartment
These fluids can accelerate systemic inflammation by activating neutrophils
Crystalloids
This nerve is responsible for eye movement and innervation of the lateral rectus muscle
CN VI (Abducens)
Sign to assess for DVT by pressing calf toward the tibia and then pt having increased pain
Moses' Sign (Bancroft Sign)
Stroke Volume Formula
CO x 1000 / HR (EDV - ESV)
Type of facial fracture that is transverse and involves the zygomatic arch and upper maxilla
LeFort III
