INPUT ARTICLE: Article: Increased levels of nitric oxide are associated with swelling in the airways, so a pulmonary specialist may test your exhaled nitric oxide levels to check for asthma when other routine tests are not providing answers. Tell your doctor about any breathing difficulties you are having. Ask about the exhaled nitric oxide test, as it may not be available in all doctor's offices or hospitals. Your doctor will usually make a separate appointment for your test so you can prepare for it. This test may be ordered if you have already been diagnosed with asthma if your doctor is testing your treatment progress or considering a new line of treatment. There are many things that can affect nitric oxide levels in your body, even in small doses. Alcohol and tobacco should be avoided for a full 24 hours before your test. Inform your doctor if you are a regular smoker. Long-term drinking habits can affect your nitric oxide levels significantly, so tell your doctor if you drink more than 1 drink a day, or drink more than 4-5 drinks a day at least once a month. While cardiovascular exercise is excellent for your health, it should be avoided for a full day before your test. Aerobic activity increases the levels of nitric oxide in your body, which may skew the results of your test. Skip any type of workout, including: Jogging or running Bicycling Jumping rope Rollerblading Dancing Speed walking Allergy shots work by introducing allergens into your system to help it build a resistance to them. As a result, an allergy vaccination may affect your nitric oxide levels for 24-48 hours after it is administered. To ensure accurate results, avoid scheduling an allergy shot within 1-2 days of your nitric oxide test. Consuming food or beverages right before your test can affect the levels of nitric oxide being released. Plan ahead so you can go at least an hour without eating or drinking anything prior to your test appointment. This includes drinking water, which can also skew test results. Nitric oxide levels in the body may be affected by other health issues and treatments. Disclose any prescription or over-the-counter medications that you are taking. If you are sick with the flu, allergies, or another ailment, tell your doctor to rule out any other causes of your symptoms. Share the results of any other breathing tests you have undergone in the past. The exhaled nitric oxide test will last about 5 minutes. Allow the technician helping you to put clips on your nose and a mouthpiece in your mouth when you are ready to start the test. Inhale and exhale slowly until the technician or doctor tells you to stop. You may have to repeat the test a few times to confirm the results. The amount of nitric oxide exhaled into the mouthpiece will be recorded for your test results.

SUMMARY: Speak to your doctor about your breathing problems. Avoid alcohol and tobacco for 24 hours prior to your test. Avoid aerobic exercise for 24 hours before your test. Do not get an allergy shot on the day before your test. Don't eat or drink within an hour of your test. Disclose any medications conditions that may affect your results. Follow the technician's instructions for breathing during the test.

INPUT ARTICLE: Article: Your USB flash drive should plug into one of the rectangular or oval USB or USB-C ports on your computer's housing. Traditional flash drives only fit one way, so don't force the drive if it doesn't fit. If your Mac uses USB-C ports, your USB-C flash drive should fit any way in which you insert it. The USB flash drive should be at least 8 gigabytes in space so that it can accommodate most operating system installation files. If you want to create a bootable USB drive on a Mac, you'll need to have an ISO file (or an image file, if you're backing up your computer's hard drive) ready to drag and drop into Terminal. This is different than how Windows handles bootable flash drives, since you can make a flash drive bootable and then save it for later when using Windows. Click the magnifying glass icon in the top-right corner of the screen. A search bar will appear. This will search your Mac for the Terminal application. It's a black box in the middle of the Spotlight search results. Doing so will open Terminal. Type diskutil list into Terminal, then press Return. Look for the USB drive that you plugged into your computer, then look at the USB drive's name under the "IDENTIFIER" heading. You'll usually find your USB drive under the "(external, physical)" heading near the bottom of the Terminal window. Your USB flash drive's name under the "IDENTIFIER" heading will normally be something like "disk1" or "disk2". Type diskutil unmountDisk /dev/disknumbermaking sure to replace "disknumber" with the disk's "IDENTIFIER" name and number (e.g., disk2)into Terminal, then press Return. Type in sudo dd if= but don't press the Return key just yet. Click and drag the ISO file (or disk image file) that you want to boot into using the USB drive into the Terminal window. This will copy the file's address into the Terminal command. You can also type in the folder path to the ISO file. This will put a space at the end of the file's address, making room for the next command. Type in of=/dev/disknumber bs=1m, again making sure to replace "disknumber" with the USB flash drive's number (e.g., disk2), and press Return. This is the password that you use to log into your Mac. As you type, you'll notice that the letters don't appear in Terminal; this is normal. Doing so submits your password and prompts your Mac to begin creating a bootable USB flash drive with your selected ISO or image file. This process can take several hours to complete, so just leave Terminal open and your Mac plugged in.

SUMMARY:
Insert a USB flash drive into your computer. Make sure that you have an ISO file. Open Spotlight . Type in terminal. Double-click Terminal . Open a list of connected drives. Find your USB drive. Select the USB drive. Enter the formatting command. Drag the ISO file into the Terminal window. Press the Space key. Enter the rest of the command. Type in your password. Press Return.
