The COVID-19 virus can cause blood oxygen to drop to dangerously low levels, even if the person feels well, or has no other symptoms. As a preventive measure, Temasek Foundation provided free oximeters to every household in Singapore, in a bid to allow residents to monitor their blood oxygen levels.
Dr Lee Kang Hoe, Lung Specialist and Pulmonologist at Gleneagles Hospital, explained, “Despite having COVID-19 infection, some patients remain asymptomatic. This is what we call ‘silent pneumonia’. Now, we have a simple medical device, the pulse oximeter, which allows us to measure the oxygen level in our bloodstream.”
Over 1 million oximeters were collected at supermarkets and pharmacies across Singapore, including NTUC Fairprice, Sheng Siong, Giant, Cold Storage, Watsons, Unity and Guardian.
Khoo Suk Li, a staff member at Sheng Siong, was glad to be part of the distribution exercise. “I find it meaningful to be able to contribute to the fight against COVID-19.”
