The risk of VAP is highest early in thecourse of hospital stay, and is estimated to be 3%/day duringthe ï¬rst 5 days of ventilation, 2%/day during Days 5 to 10 ofventilation, and 1%/day after this (17).
there is a difference. There are other here who could elaborate further but MIG stands for metal inert gas. This is Argon or c02. Inert meaning the gas has no affect on the weld except to shield it from oxidation, from the atmosphere. MAG is metal active gas.
Both welding processes use a shielding during the welding process (stick welding does not require a shielding gas, therefore is used widely when welding outside). TIG welding uses pure Argon welding gas, whereas MIG welding generally uses a mix of 25% Argon, 75% CO2.
