MI PATTERNS - Answer 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 - Answer Gas pressure increases as Temp increases Gas expands in a heated tank Henry 's Law - Answer Decompression Dalton's Law - Answer Molecules shrink under pressure. It takes more molecules to fill the same space. More altitude=more O2 needed. Graham's Law - Answer 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 - Answer Trapped gas expands with altitude. (Air splints, Chest tubes, ET Tubes, Bowels) Gay-Lussac's Law - Answer Pressure in the tanks go down as temperature goes down
