Pulse Oximeter
1.A small medical device that clips onto a person’s finger, pulse oximeter measures pulse and the percentage of oxygen in the blood within 15 seconds.
2.The normal blood oxygen saturation level for someone who is healthy will be around 95%–100% per cent.
3.If you've been diagnosed with COVID-19, you may want to monitor your oxygen level to determine whether your condition is worsening or improving .
4. COVID-19 can bring on what's called COVID pneumonia which eventually causes shortness of breath, it's possible that someone infected with the novel coronavirus might be in the early stages of COVID pneumonia – including a drop in blood oxygen level — without experiencing any difficulty breathing.
5.In such cases, a pulse oximeter might signal that you're in trouble before you realize it. If the number drops to 92% or lower, that's generally the level where a doctor might put you on supplementary oxygen and keep you in the hospital for observation.
So, it’s better to be well prepared rather than be surprised.
