-
Leads that view the inferior wall of the heart
II, III, aVF
-
V1 & V2 View
- Interventricular Septum
- (involve the left coronary artery)
-
ST-depression in leads: V1, V2, V3, V4 =
Posterior MI
-
T-wave represents
Repolarization of ventricles
-
P-wave represents
Atria depolarization
-
Peaked T-waves =
Hperkalemia
-
Which side will the trachea deviate with a tension pneumothorax
Away from the injury site
-
Bleeding or other fluid drainage from the nose following head trauma is indicative of what kind of fracture
Cribriform plate
-
Internal hemorrhage cannot be controlled in the prehospital setting—period!
Fact
-
Signs of a massive hemothorax include
- Collapsed jugular veins
- Unilaterally diminished or absent breath sounds
-
Injury above what vertebrae will cause a patient to stop breathing
C2
-
Signs of brainstem injury
- Posturing
- Decorticate (flexor)
- Decerebrate (extensor)
-
Signs of spinal cord injury
- Priapism
- Parethesia
- Paralysis
-
Drug dosage formula
- desired dose x volume on hand /
- concentration
-
Dopamine
2 - 10 mcg/kg/min
receptors stimulated
- Beta 1: increased cardiac output
- Alpha: Vasoconstriction
-
Dopamine
10+ mcg/kg/min
receptors stimulated
Alpha-adrenergic
-
NAVEL
- Narcan
- Atropine
- Vasopressin
- Epinephrine
- Lidocaine
-
Full thickness burns
- Painless
- Charred, white, leathery skin
-
Ensure an open and patent airway before assessing rate and quality of breathing
Fact
-
Which ET blade is best for intubation on infants
- Miller
- (because epiglottis is under developed)
-
A pregnant patient's airway is more
anterior or posterior?
- Anterior
- (making it more difficult to intubate)
-
Deep partial-thickness burns
- Edema
- Blister formation
- Decreased sensation around burn
-
Type of shock:
Impaired sympathetic nervous system tone which results in vasodilation
Perfusion becomes inadequate & hypotension occurs
Neurogenic shock
-
Symptomatic 3rd degree heart blocks always require
TCP
-
Right coronary artery supplies
The inferior wall
