CFRN STUDY GUIDE
MI PATTERNS *** LISA P.
LATERAL: I,aVL, v5,v6 (LCA/RCA-high lateral wall L Vent)
INFERIOR: II, III, aVF (RCA-inferior & posterior wall L Vent) Wenckebach
SEPTAL: V1, V2 (LCA/bundle branches)
ANTERIOR: V3, V4 (LCA, LAD-anterior wall L Vent)
POSTERIOR: V1,V2,V3,V4:ST Depression (RCA/LCA-L Vent posterior wall)
Charles's Law *** Gas pressure increases as Temp increases
Gas expands in a heated tank, need more AC power in high heat, less in cold.
Henry 's Law *** Decompression: the amount of dissolved gas in a liquid is proportional to its partial
pressure above the liquid
Dalton's Law *** Molecules shrink under pressure. It takes more molecules to fill the same space. More
altitude=more O2 needed.
Graham's Law *** Diffusion rate of gas thru a liquid is related to solubility of the gas. Higher to Lower
Concentrations. (mucous in the lungs with O2
Boyle's Law *** Trapped gas expands with altitude. (Air splints, Chest tubes, ET Tubes, Bowels)
Gay-Lussac's Law *** Pressure in the tanks go down as temperature goes down (rigid container)
Murphy Sign *** Gallbladder, unable to take deep breath during palpation under the right ribs.
Cullen Sign *** Appearance: Bruising of the umbilicus.
,Cause: Retroperitoneal bleed, pancreatitis, Trauma, ruptured ectopic
Grey-Turner Sign *** Appearance: Bruising of the flanks.
Cause: Retroperitoneal bleed, pancreatitis, Trauma, ruptured ectopic
Asterixis *** Liver, Hepatitis, Hands held out and shaking
Cushing's Reflex *** Increased ICP, widening pulse pressure, bradycardia, resp changes (cheyne stokes).
