Filter to extract matching values. Filter every nth row. In this example, the goal is to extract every 3rd record from the data shown, but there no row number information in the data Unique values by count.
You can see a more basic example here. Max value with variable column. For example, to get the value at row 2 and column However, when the criteria used to match a value becomes more complex, you can use Boolean logic to create Although FILTER is more commonly used to filter rows, you can also filter columns, the trick is to supply an array with the same number of columns as the source data.
In this example, we construct the array we need The trick is to use an include argument that operates on columns instead of rows. In this example, we use a hard-coded array constant to Filter and transpose horizontal to vertical. The goal is to filter the horizontal data in the range C4:L6 to extract members of the group "fox" and display results with data transposed to a vertical format.
For convenience and readability, we have two named ranges Filter exclude blank values. In this case, we want to apply criteria that requires all three columns in the source data Name, Group, and Room to have data. Cell contains which things. In this example the goal is to check a cell for several things at once, and return a comma separated list of the things that were found.
In other words, we want check for the colors seen in column E and list the colors Filter data between dates. This formula relies on the FILTER function to retrieve data based on a logical test created with a boolean logic expression. The array argument is provided as B5:D15, which contains the full set of data without headers Related videos. In other words, values that appear more than once in a set of data. New dynamic array functions in Excel.
With the introduction of dynamic array formulas, Excel includes 6 brand new functions that directly leverage dynamic array behavior. In this video, we quickly demo all 6. How to show top or bottom n results. How to count unique values. Filter with dynamic dropdown list. In this video, we'll build a dropdown list using dynamic arrays to filter data by color. The dropdown list is created with data validation.
Related functions. Values can be text, numbers, dates, times, etc. The range or array used to sort does not need to appear in results. See also. Dynamic array formulas in Excel. Email HP.

Arteries are the blood vessels that bring oxygen-rich blood and nutrients to the body.
A deep vein thrombosis DVT is a blood clot that forms in a vein deep inside the body. A clot occurs when blood thickens and clumps together. In most cases, this clot forms inside one of the deep veins of the thigh or lower leg. The veins in your legs have tiny valves that help keep blood moving back up toward the heart. But a DVT may damage one or more of these valves.
This causes them to weaken or become leaky. When this happens, blood starts to pool in your legs. This can also happen if you are immobile for a long period of time. Normally, muscles in the leg help blood move up in the veins when the muscles contract. When blood flows very slowly through the veins, this increases the risk that cells in the blood will stick together and form a clot. DVT is a serious medical condition that can cause swelling, pain, and tenderness in your leg.
In some cases, a deep clot in a leg vein can break free and stick in a vessel in the lung. This can cause a blockage in the vessel called a pulmonary embolism. Pulmonary embolism can cause severe shortness of breath and even sudden death. An IVC filter is one method to help prevent pulmonary embolism.
Your inferior vena cava IVC is the major vein that brings oxygen-poor blood from the lower body back to the heart. The heart then pumps the blood to the lungs to pick up oxygen. An IVC filter is a small, wiry device. When the filter is placed in your IVC, the blood flows past the filter. The filter catches blood clots and stops them from moving up to the heart and lungs. This helps to prevent a pulmonary embolism. The IVC filter is placed through a small incision in a vein in your groin or neck.
A thin, flexible tube catheter is inserted into this vein. The catheter is then gently moved into your IVC. A collapsed IVC filter is sent with the catheter. The filter is left in place, and the catheter is removed. The filter then expands and attaches itself to the walls of the IVC. It may be left in place permanently.
In some cases, it may be removed after a period of time. You may still get a DVT. The filter helps to protect you from a life-threatening pulmonary embolism if you have a DVT. Anything that slows the movement of blood through your veins increases your risk of DVT. A variety of conditions can increase your chance of getting a DVT, such as:. A blood-thinning medicine such as warfarin is also used to treat people who are at risk of pulmonary embolism.
Blood thinners may be used alone to prevent pulmonary embolism. But in some cases, they may be used along with the IVC filter. However, some people have conditions that make this kind of medicine unsafe for them. They may have dangerous bleeding when taking blood thinners.
This may include someone who has bleeding in the brain from a trauma or fall, or has bleeding in the digestive tract. Excess bleeding in these areas can be life-threatening. In these cases, your healthcare provider may instead advise an IVC filter alone to protect against pulmonary embolism. Your risks may vary based on your overall health, the severity of your condition, and other factors.
Ask your provider about which risks apply most to you. Talk with your healthcare provider about what to expect during your procedure. It usually takes about an hour.
The procedure is done by an interventional radiologist and a team of specialized nurses. A typical procedure may go like this:. After the procedure, you will spend several hours in a recovery room. You may be sleepy and confused when you wake up. Your healthcare team will watch your vital signs, such as your heart rate and breathing.
You may have a headache or nausea, but these should go away quickly. You may be able to go home the same day. Your healthcare provider will tell you more about what to expect.
