In patients? I assume. There are a couple of ways. The easiest is to place a probe on a finger (or ear lobe) that has a red light. Because blood with oxygen is differently colored than blood without oxygen, the light coming through the finger or ear lobe will vary, depending on the amount of oxygen in the blood. The machine correlates the color to the percentage of hemoglobin molecules that are carrying oxygen. Anything about 96% is good.
The older method involves a "blood gas" sample, which is drawn from an artery, usually the radial artery in your wrist (the pulse on the thumb side). The sample is taken to the lab, where the type and amount of gases in the blood are analyzed (usually oxygen and carbon dioxide). This takes longer and is obviously painful, but it is more accurate, and the best way to check carbon dioxide levels (which rise if you are not breathing enough).
Oxygen is available for patients who are not breathing well enough to get by on regular air.
compressibility
Place a glowing splint into the test tube. If the glowing splint relights, then oxygen is present, otherwise oxygen is not present.
Gas can be compressed easily.
The glowing splint will relight if you place it in a flask with oxygen. Scientists do this as a test for oxygen so if it relights, then that means the flask contains oxygen.
some of the patients in hospitals need a higher percentage of oxygen to help them breathe.
an PERSON GETS ARTIFICIAL OXYGEN FROM THE CYLINDER that are attached to the hospitals.
Oxygen is available for patients who are not breathing well enough to get by on regular air.
compressibility
oxygen is used for many things like in hospitals when people are having difficulties ti breath.
The standard test for oxygen is that it relight a glowing splint.
Place a glowing splint into the test tube. If the glowing splint relights, then oxygen is present, otherwise oxygen is not present.
well most hospitals have an oxygen generator as they consume quite a bit of it. is this what you meant?
All people whom work in hospitals need to take the patient care technician test, so they will be prepared. It's important for all the people who work in hospitals to do so.
Oxygen is used in order to assist the breathing of many patients
Gas can be compressed easily.
You can test for oxygen by placing a glowing splint (not lit but not out) into the test tube where you think oxygen is present. If the splint relights, that means that it is oxygen. If this doesn't happen, then in your case it will be nitrogen.
