It's not so much that it's pressure treated as that it is plywood. Plywood will eventually delaminate when the glue dissolves; and that will have to do with how thick the laminates are; especially the one on top. You will also probably get some deterioration along the edges.
Google+4. The debt service coverage ratio (also referred to as the DSCR) is a measurement used by lenders to determine if a business is able to meet its debt servicing obligations through its operating income during a given period of time.
In respiratory physiology, the ventilation/perfusion ratio (or V/Q ratio) is a measurement used to assess the efficiency and adequacy of the matching of two variables:  1 V â ventilation â the air that reaches the alveoli. 2 Q â perfusion â the blood that reaches the alveoli.herefore, under these conditions, the ideal ventilation perfusion ratio would be about 0.95. If one were to consider humidified air (with less oxygen), then the ideal v/q ratio would be in the vicinity of 1.0, thus leading to concept of ventilation-perfusion equality or ventilation-perfusion matching.
