LATERAL: I,aVL, v5,v6 (LCA/RCA-high lateral wall L
Vent)
INFERIOR: II, III, aVF (RCA-inferior & posterior wall L
MI PATTERNS Vent)
SEPTAL: V1, V2 (LCA/bundle branches)
ANTERIOR: V3, V4 (LCA-anterior wall L Vent)

Vent posterior wall)
Gas pressure increases as Temp increases
Charles's Law
Gas expands in a heated tank
Henry 's Law Decompression
Molecules shrink under pressure. It takes more
Dalton's Law molecules to fill the same space. More altitude=more
O2 needed.
Diffusion rate of gas thru a liquid is related to
Graham's Law solubility of the gas. Higher to Lower Concentrations.
(mucous in the lungs with O2
Trapped gas expands with altitude. (Air splints, Chest
Boyle's Law
tubes, ET Tubes, Bowels)
Pressure in the tanks go down as temperature goes
