Problem: Write an article based on this summary: Make sure you have the right size cannula. Attach the end connector to the oxygen source. Adjust the amount of oxygen that flows through the tubes. Turn the cannula so the prongs are curved downward. Insert the prongs into your nostrils. Lift the tubes and fit them over your ears. Move the slider up the tubes to adjust the fit.

Answer: Most brands of cannulae come in infant, pediatric, and adult sizes, so select the one that best fits you for your size. The cannulae should fit snuggly in your nostril so that it doesn't come out, but it shouldn't be so long that goes far back into the nostril. Some brands may have extended sizes, such as small, medium, and large for adults, and premature through pediatric for children, giving you more options. In this case, choose the one that feels the most comfortable when placed in your nostrils.  If the cannula is rubbing uncomfortably against your nostrils, it may be too large. If it's pinching, it may not be the correct size. At one end of the nasal cannula tube, you’ll see a connector that hooks onto your oxygen tank or converter. Slip the connector over the end of the oxygen line coming from your tank to connect the nasal cannula. Make sure the connector is seated tightly onto the oxygen line so none of the gas can escape. Place the connection against your arm to feel for any leaking oxygen. You may also be able to smell escaped oxygen. Your healthcare provider will prescribe a flow rate for you. Turn the knob on the machine so that the dial is set to this exact number every time, and do not change it unless your doctor tells you to. Changing the flow rate could result in you getting more or less oxygen than you need, which could lead to health complications. Try using a pulse oximeter to monitor your oxygen. If it's always at 100%, turn your oxygen down a little. Most cannulae today have curved prongs so they fit more naturally inside the nostrils. Hold the cannula so the prongs are pointing up toward the ceiling and curve down toward you. If the cannula does not have curved prongs, just hold it so the prongs are pointed upward and angled toward your body. Place the cannula in as far as it will go. If the cannula is properly connected, you will feel a gentle flow of air. If it's the proper size, the prongs should sit comfortably in your nostrils. Make sure the tubes that connect the nasal prongs to the oxygen delivery system are fitted snugly over your ears. This will help hold the cannula in place, even if you’re moving around or sleeping. If having the tubes looped behind your ears is uncomfortable, you may prefer to rest the headset behind your head. Instead of looping the tubes over your ears and under your chin, turn the cannula so the tubes go from your nostrils down toward the back of your neck, with the slider resting at the base of your neck. The slider is the small piece on the tubes which you can move up and down to tighten or loosen the headset. Push the slider up until it is just under your chin. The headset should be snug, but you still should be able to fit two fingers between the tubes and your chin. If the cannula causes indents in your skin, it is too tight.


Problem: Write an article based on this summary: Make the mental switch to research. Take a break if you need to. Do some research into topics you love. Learn about professors in PhD programs. Apply to a PhD program.

Answer: When you're an undergrad or even a master's student, your primary focus is on taking classes and learning from your professors. While you'll still likely have some required courses as a PhD candidate, the focus is placed on you developing your own research. You're producing the content instead of merely consuming it. If you're not sure exactly what you want to research as a PhD candidate, it can make sense to take a break after your undergraduate or master's program. Of course, you don't want to wait too long, but you can take a year to figure out the direction you want to go in. Take the time to gain some experience. Apply for lab positions so you can get a feel for what it's like to do research in a lab full time. If you're still in undergrad, try taking classes in topics that interest you or in topics you haven't explored yet. When you come across things that you find interesting, dive deeper. Read more outside of class to see if that could become your PhD focus. Often, your "original" research may just be something you work on under the direction of a professor. That is, you may be assigned your research work and perform the research with guidance from the professor. Choosing a school with professors whose research you enjoy is a great way to focus your work. As your work gets more individual, you want to work with professors who have similar interests. Check out the requirements for each program on the school's website. Every department has different requirements for who they admit to their program. The earlier you understand what they will be looking for in different schools, the higher your chances will be to prepare a great application. Often, you'll need to have a certain level of knowledge in the fields of mechanics, electromagnetism, atomic and nuclear physics, quantum mechanics, and advanced calculus.  Submit all the appropriate paperwork for your application, including your transcripts, academic references, and your basic application.  In many cases, you'll need to write a personal statement or research proposal, as well.


Problem: Write an article based on this summary: Find an optometrist or opthamologist. Visit your eye doctor regularly. Complete a full eye exam.

Answer:
Search online for an optometrist or opthamologist in your area. An optometrist is trained to detect a number of eye diseases and can help prescribe corrective lenses. An ophthalmologist can perform eye surgery as well as detect eye diseases, prescribe medication, and prescribe corrective lenses. Do not replace regular visits to the optometrist with online vision tests. These tests should only be used to give you a general understanding of your quality of vision. A trained optometrist can give you a prescription for corrective lenses and can diagnose eye diseases such as glaucoma and cataracts.  School aged children should have their eyes tested every one to two years. Adults between the ages of 20 and 40 should have their eyes tested once every five to ten years. Adults between the ages of 40 and 55 should have their eyes tested every two to four years. Adults between the ages of 55 and 65 should have their eyes tested every one to three years. Adults over the age of 65 should have their eyes tested every 1-2 years. An eye examination, unlike an online vision tests, looks at more than just your vision. For instance an eye exam also evaluates your ocular motility, visual fields, eye structure, and screens for eye diseases such as glaucoma and macular degeneration.
