Pulmonary edema occurs when the alveoli fill up with excess fluid seeped out of the blood vessels in the lung instead of air. This can cause problems with the exchange of gas (oxygen and carbon dioxide), resulting in breathing difficulty and poor oxygenation of blood.
Currently buildings are limited to a height of 200 meters and are subject to not contrasting the view of Mount Royal, the city's central green space, with the only exception being antennas and communication towers, that are allowed to reach 223 metres (732 ft) above mean sea level.
Total length of all walls in feet. Round up to the nearest foot, and be sure to count all length. A rectangular garage that's 8 x 15, for example, is 8 + 15 + 8 + 15 = 46 feet total in length. The total length of a house with ells, extensions, and bays needs to be calculated wall by wall. Wall height in feet: If you don't know how tall the wall is, assume about 10 feet for each story, or 20 feet for a two-story house and 30 feet for a three-story house. If you have a pitched roof that creates a higher wall on one side of the house than the other, use the average height. For each overhang, add two feet to the wall height.
