Pulse oximeter sales skyrocket: this £30 Covid monitoring gadget could save your life


Pulse oximeters are shaping up to be the new hero of lockdown, with sales increasing tenfold, according to new stats. 

These compact devices clip on the end your finger and are used to test oxygen levels in your blood. Some covid-19 sufferers have low blood-oxygen levels but do not experience obvious symptoms such as breathlessness. This often means they don’t seek medical attention, which can lead to much more serious deterioration further down the line (read more about ‘silent hypoxia’ in this BMJ article). The NHS recommends  pulse oximeters as a simple way to monitor oxygen saturation while isolating at home.
