Article: Subtract the standing (1 minute) values from the laying down readings. Also subtract the standing (3 minute) values from the laying down values, for a comparison and to see how quickly the body adapts.  Judge whether the person is likely to be suffering from orthostatic hypotension. If the systolic pressure decreases by 20 mm Hg or if the diastolic pressure decreases by 10 mm Hg, they likely have this condition. Note that the condition is diagnosed based on the 1 minute standing blood pressure, not the 3 minute one (the 3 minute one simply provides a comparison to see how quickly the body adapts when given more time to stand). Also consider whether the patient’s pulse increases by a normal rate. It is usual for the pulse to increase by 10 to 15 beats per minute. However, if the beats increase by 20 beats per minute or more, she should see a doctor for further evaluation. Regardless of the difference between the blood pressure values lying down and standing, if the person feels lightheaded and/or dizzy consistently upon standing he needs to be seen by a doctor for a professional evaluation of what may be causing these symptoms. The diagnosis of "orthostatic hypotension" can be based on these symptoms alone, regardless of the difference in numerical blood pressure values, so it is important to ask the person about any symptoms he may be experiencing when he suddenly stands. Having "orthostatic hypotension" (low blood pressure immediately upon standing) is very common, particularly among the elderly. It leads to symptoms such as light-headedness and/or dizziness upon standing, and it poses the risk of someone passing out when she stands up due to insufficient blood flow. It is important to be aware of "orthostatic hypotension" in order to correct or improve it as best as possible.  In the elderly, common causes of orthostatic hypotension include medications the person is taking, dehydration, insufficient salt consumption (although too much salt can lead to overly elevated blood pressure), or simply a delayed response of the blood pressure after standing, which, to some degree, correlates with the natural aging process. Orthostatic hypotension is far less common in young people. However, it can sometimes occur as the result of other diseases (Parkinson's disease, paraneoplastic syndromes, etc.), extreme dehydration, or large amounts of blood loss secondary to trauma.
Question: What is a summary of what this article is about?
Evaluate the results. Consider the person's symptoms. Understand why it is important to measure orthostatic blood pressure.

The Snipping Tool is available in all versions of Windows Vista, 7, 8 and 10 except the Starter and Basic editions. It is not available in Windows XP.  In Windows Vista and 7, click the Start button, select All Programs, select Accessories, and select the Snipping Tool from the list. In Windows 8, simply start typing snipping tool while on the Start screen and select it from the Search results. In Windows 10, click Start {"smallUrl":"https:\/\/www.wikihow.com\/images\/0\/07\/Windowsstart.png","bigUrl":"\/images\/thumb\/0\/07\/Windowsstart.png\/30px-Windowsstart.png","smallWidth":460,"smallHeight":460,"bigWidth":"30","bigHeight":"30","licensing":"<div class=\"mw-parser-output\"><p>I edited this screenshot of a Windows icon.\n<\/p><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"http:\/\/en.wikipedia.org\/wiki\/Public_domain\">Public Domain<\/a><br>\n<\/p><\/div>"}, type in snipping tool, and select Snipping Tool from the Search results. "Rectangular Snip" is chosen by default. Click the Arrow button next to the Mode button to change the Snip shape:.   Free-form Snip lets you draw any shape with your mouse. The area inside the shape will be snipped.  Rectangular Snip lets you select a rectangular area, which will be snipped.  Window Snip lets you choose a window to snip.  Full-screen Snip snips the whole screen, with all windows (except the Snipping Tool window) included. By default, any snip you make will have a red border around it. You can disable or change this by clicking the Tools tab in the top-left side of the Snipping Tool toolbar, selecting Options from the drop-down menu, and unchecking the box next to “Show selection ink after snips are captured”. This will remove the border from any future snips. Click the New button to start the selection. The screen will fade, and you can draw your Snip area, or select the window if you chose Window Snip. Release the mouse when selecting to create the Snip. If you had Full-screen Snip selected, your Snip will automatically be created once you click New. Once you create the Snip, it will open in a new window. You can use the Pen tool to draw on it and make notes, and use the Highlight tool to draw attention to text. The Erase tool will only erase annotations, not the screenshot itself. Click the floppy disk icon to open the save dialog. Type in a name for the screenshot and change the "Save as type:" field if desired. You can now send the screenshot by email or put it on a website.  PNG is the default format in Windows 7 and 8. It's a lossless compressed format, which means that it will take high-quality screenshots at a small file size. It is the recommended format for taking screenshots. JPG or JPEG is the default format in Windows Vista. It is a lossy format, meaning that the screenshot will look slightly blocky and some colors may be a bit off. It's mainly designed for photographs, and not recommended for screenshots. GIF is unsuitable for reproducing color photographs, but well-suited for images such as graphics or logos with solid areas of color, resulting in crystal sharp edges between color areas. By default, the Snip is copied to the clipboard when you create it. This means you can paste it into Paint or Word, much like you would with a full-screen screenshot. In Paint, you can make more edits than you can in the Snip annotation editor. To paste the Snip, open a window that supports pasting and press Ctrl+V.
