RICKY'S CFRN STUDY GUIDE LATEST 2023 GRADED A 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.
