What is an Oximeter?

Temasek Foundation is providing one free oximeter for every Singapore household to enable everyone to monitor their blood oxygen levels regularly.

An oximeter measures blood oxygen levels and pulse rates.

The COVID-19 virus can cause blood oxygen to drop to dangerously low levels, even when you feel well, or have no other symptoms of the virus. This is known as “silent pneumonia”.

If left untreated, the low oxygen levels can damage vital organs, with very serious consequences.
