This opens the main Pixlr website. It's a link in an oval-shaped button near the center of the page. Depending on your browser, you may be prompted to enable Adobe Flash.

Click one of the following options in the window, and then follow the on-screen instructions to load the image or canvas: CREATE A NEW IMAGE: This option starts with a blank canvas on which you can draw or paint your own custom image.

Font: If you plan to type on your image, this is where you'll find a selection of fonts to choose from. Freebies: You can find fun backgrounds, vector images, and other resources in this menu. The toolbar is the icon panel that runs along the left side of the page. Each of these icons represents a different tool you can use to edit your image. To find out what a tool does, hold the mouse cursor over its icon. When you click a tool on the toolbar, additional options for that tool will appear near the top of the page (below the menu bar). It's the first box (titled "Navigator") running along the right side of the page. If you don't see this panel, click the View menu at the top of the page, then click Navigator. This panel displays a smaller version of your image. Use it to quickly zoom in, out, or change which part of the image appears on the screen. Drag the slider at the bottom of the panel to the right to zoom in, and to the left to zoom out. If you're zoomed in pretty far and want to see a different part of the image, drag the red square at the center of the Navigator panel to the part of the image you want to bring into view. It's the second panel on the right side of the screen. If you don't see it, click the View menu and select Layers. This panel shows the layers in your project. To create a new layer, click the small sheet of paper with a down-turned corner at the bottom of the panel. Click a layer's name to work on that layer. Every layer has a check box to the right of its name. Toggle the check mark to choose whether a layer appears on the image. To delete a layer, click its name in the panel, then click the trash icon at the panel's bottom. It's on the right side of the screen below the Layers panel. If you don't see it, click the View menu at the top of the page, then select History. This displays a list of every editing action you've taken on this project. This is helpful in determining which actions to replicate or which actions to roll back while reviewing your edited picture. You don't have to have a Pixlr account to use the editing tools. However, if you want to save your images to Pixlr's online service so you can work on them later, an account will be necessary. Here's how to create one: Click Sign up at the top-right corner of the page. Fill out the form and click OK. Review the agreement and click Agree. This creates your account and logs you in.

Summary: Go to the Pixlr.com. Click OPEN PIXLR EDITOR. Select a photo upload or creation option. Browse the menu bar. Check out the toolbar. Try the "Navigator" panel. Work with layers in the Layers panel. Manage the changes you've made in the History panel. Create an account (optional).

This method calculates your total blood volume in milliliters. To perform the calculation, you will need your height in inches and your weight in pounds. The formula is: (0.006012 x Height3{\displaystyle ^{3}})+(14.6 x Weight)+604. If you have your height in centimeters and your weight in kilograms, you will first need to convert them to inches and pounds, respectively. 1 centimeter is 0.39 inches. 1 kilogram is 2.2 pounds. Calculate the height function of the formula. Cube your height in inches and then multiply it by 0.006012. Calculate the weight function. Multiply your weight in pounds by 14.6. Add the height function to the weight function. Add 604. This method uses the average number of milliliters of blood per kilogram of body weight that a man has. This method is also called the reference book method. Your weight should be in kilograms. If you need to convert pounds to kilograms, 1 pound is 0.45 kilograms. Multiply your body weight in kilograms times the average for men: 75 milliliters of blood per kilogram. This will give you your estimated blood volume in milliliters. Not all types of tissue have the same amount of blood in them. This means that if a person is obese or very thin, it will influence the accuracy of the calculations. Gilcher's Rule of Fives makes adjustments for this in the estimated amount of blood per kilogram of body weight. If you know your weight in pounds, convert it to kilograms by multiplying by 0.45. Then multiply your body weight in kilograms by one of these values to get your estimated total blood volume in milliliters: Muscular men have 75 mL of blood per kilogram of body weight. Normal men have 70. Thin men have 65. Obese men have 60.

Summary: Use Nadler's equation. Estimate your total blood volume. Make adjustments using Gilcher's Rule of Five if needed.

Ask your doctor if you are supposed to take your usual morning medications. If you have diabetes, ask if you can take insulin or oral blood sugar medications before the test. Tell your doctor if you have a history of asthma, kidney or bleeding problems. Special precautions may be needed if you have one of these conditions. You may be asked not to take aspirin (including other products that contain aspirin) or prescription blood thinners for several days before the test. Discuss with your doctor when you can resume these medications. Pregnant women need to be cautious about doing certain things to avoid harming the fetus. If you are or might be pregnant, or if you just had a baby, discuss these details with your doctor so that you can decide on the best course of action. It is extremely important to tell your doctor if you are pregnant because an angiogram is needed to detect a potential coronary artery blockage. This may result in the need for reperfusion stenting to restore blood flow to the heart. Use formula for one to two days after your angiogram if you are breast-feeding until the dye has passed through your body. Your doctor will determine what testing you need to undergo before your angiogram. Make sure you follow your doctor's directions and complete any recommended testing. You may need to have blood taken or an electrocardiogram done before the angiogram.
Summary: Talk to your doctor about your medical history. Tell your doctor if you are pregnant. Complete all necessary pre-procedure tests.
