2. Splint (laboratory equipment) - Wikipedia

   en.wikipedia.org/wiki/Splint_(laboratory_equipment)

   The glowing splint test is a test for an oxidising gas, such as oxygen. [4] In this test, a splint is lit, allowed to burn for a few seconds, then blown out by mouth or by shaking. Whilst the ember at the tip is still glowing hot, the splint is introduced to the gas sample that has been trapped in a vessel. [4] Upon exposure to concentrated ...

3. Nitrous oxide - Wikipedia

   en.wikipedia.org/wiki/Nitrous_oxide

   Nitrous oxide is a colourless gas with a faint, sweet odour. Nitrous oxide supports combustion by releasing the dipolar bonded oxygen radical, and can thus relight a glowing splint. N. 2O is inert at room temperature and has few reactions. At elevated temperatures, its reactivity increases.

   English: Glowing splint test for oxygen: A glowing splint is put into flasks containing different gases. Three different results are observed. Three different results are observed. Magyar: oxigén kimutatása parázsló gyújtópálcával: Egy parázsló gyújtópálcát különböző gázokat tartalmazó lombikokba helyezünk.

5. Pulse oximetry - Wikipedia

   en.wikipedia.org/wiki/Pulse_oximetry

   A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements. [4]

6. Oxygen saturation - Wikipedia

   en.wikipedia.org/wiki/Oxygen_saturation

   Oxygen saturation (symbol SO2) is a relative measure of the concentration of oxygen that is dissolved or carried in a given medium as a proportion of the maximal concentration that can be dissolved in that medium at the given temperature. It can be measured with a dissolved oxygen probe such as an oxygen sensor or an optode in liquid media ...

   [specify] [2] [3] A glowing splint can be used to show that the gas produced is oxygen. [9] The rate of foam formation measured in volume per time unit has a positive correlation with the peroxide concentration (v/V%), which means that more foam will be generated per unit time when a more concentrated peroxide solution is used.
