RICKY'S CFRN STUDY GUIDE (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)
SEPTAL: V1, V2 (LCA/bundle branches)
ANTERIOR: V3, V4 (LCA-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 Henry 's Law - ✔️ Decompression 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 Murphy Sign - ✔️ Gallbladder, unable to take deep breath upon palpation under the right ribs.Cullen Sign - ✔️ Retroperitoneal bleed, pancreatitis, Trauma, Bruising of the umbilicus.Grey-Turner Sign - ✔️ Retroperitoneal bleed, pancreatitis, Trauma, Bruising of the flanks. 1 / 2
Asterixis - ✔️ Liver, Hepatitis, Hands held out and shaking Cushing's Reflex - ✔️ Increased ICP, widening pulse pressure, bradycardia, resp changes (cheyne stokes).
