The average American family uses more than 300 gallons of water per day at home. Roughly 70 percent of this use occurs indoors. Nationally, outdoor water use accounts for 30 percent of household use yet can be much higher in drier parts of the country and in more water-intensive landscapes.
Cardiac catheterization. Overview. Cardiac catheterization (kath-uh-tur-ih-ZAY-shun) is a procedure used to diagnose and treat cardiovascular conditions. During cardiac catheterization, a long thin tube called a catheter is inserted in an artery or vein in your groin, neck or arm and threaded through your blood vessels to your heart. Using this catheter, doctors can then do diagnostic tests as part of a cardiac catheterization.
Cardiac catheterization is done to: 1  Check blood flow and blood pressure in the chambers of the heart. 2  Check the pumping action of the heart. 3  Find out if a congenital heart defect is present and how severe it is. 4  Check blood flow through the heart after surgery. 5  Find out how well the heart valves work.
