Oxygenometer or oximeter is a device that aims to measure the level of oxygen in the blood. Normally we have to have a blood oxygenation level ranging from 96 to 98%, according to experts. When it drops to lower levels than indicated it can be understood that there is respiratory failure and with the indicated apparatus it can be controlled that the blood level is adequate. It is very useful in the times we live in since the Covid-19 virus affects and attacks the airways causing an inability to oxygenate.
