Arterial clots form in the arteries and cause immediate symptoms. This is due to the fact that the clot prevents oxygen from reaching vital organs. This can lead to stroke, heart attack, and even paralysis. Venous clots form in the veins and develop slowly over a long period of time.
1 Many kitchen exhaust fans are part of a range hood, which can cost $30-$4,500, depending on size, type and cfm; installation adds another $250-$1,500, depending on whether the project is simply connecting and hanging the range hood, or if new metal ductwork must be installed to exhaust the air outdoors. It can cost $150-$600 or more for a powerful but quiet fan with most or all of the options -- decorative light fixture, heater, nightlight, timer, humidity sensor (turning the fan on whenever needed) and Energy Star rating.
