It keeps the bone in place so it can heal properly.
To test for the presence of oxygen using a splint test, you first burn a splint until it smolders. Then, you blow out the flame and introduce the smoldering splint into the gas being tested. If oxygen is present, the splint will reignite due to the oxygen supporting combustion.
First you need rigid material for support, for comfort some padding, and something to keep the splint in place. For example cardboard or a straight stick for rigid material, towels or clothing for padding, and tape to keep it in place.
You light a splint and then light the bunson burnor with the fire on the splint.
The test for oxygen is to insert a glowing splint into a test tube and see if it glows brighter or re-ignites.
Immobilize it using a splint, use an ice pack to lessen the inflammation.
Rubber bands should not be used to secure a splint as they can cut off circulation and cause further injury. It is best to use medical tape or bandages specifically designed for this purpose.
One common way to test for the presence of oxygen is by using a glowing splint test. If you bring a glowing splint near a sample suspected to contain oxygen, it will ignite in the presence of oxygen. Another method is using a chemical like potassium permanganate, which will change color in the presence of oxygen.
To identify gases using a wooden splint and a flame, you can perform two tests: For hydrogen, introduce a lit wooden splint to the gas; if it produces a characteristic "pop" sound, hydrogen is present. For oxygen, place a glowing (but not burning) wooden splint into the gas; if it reignites, oxygen is confirmed. For carbon dioxide, passing the gas over a glowing splint will extinguish it, indicating the presence of carbon dioxide.
You can test for the presence of hydrogen gas using a lit splint test. When a lit splint is exposed to hydrogen gas, it will produce a squeaky pop sound, indicating the presence of the gas. This test is based on the highly flammable nature of hydrogen gas.
A buddy splint, such as taping one broken finger to the other.
The easiest method is to collect it in an upturned test tube, and place a lighted splint into it. If it goes out, pops, etc. it's not O2. If it burns much brighter, it is.
