Introduction
In this article, we will study How To Use Your Pulse Oximeter.
As you have symptoms of Covid-19, you – or your carer – have received a diary and pulse oximeter.
Covid-19 is a viral illness, which for most people is mild, but it can quickly become serious for some. That is why we need you to monitor your breathing, heart rate, and oxygen level in your blood.

By recording these measurements in the diary provided, you can help your GP – or 111 – decide on the best treatment for you.
A pulse oximeter monitors how fast your heartbeats and the level of oxygen in your blood.
To accurately assess your progress with Covid-19. An ideal blood-oxygen level is between 95 and 99%. A perfect heart rate is between 50 and 90.
How to use a pulse oximeter
- Remove any nail polish or false nails and warm your hand if cold.
- Rest for at least five minutes before taking your measurement.
- Rest your hand on your chest at heart level and hold it still.
- Switch on the pulse oximeter and place it on your middle or index finger.
- The reading takes time to steady. Keep the pulse oximeter in place for at least a minute or longer if the reading is not stable.
- Record the highest result once it has not changed for five seconds.
- Identify each reading carefully.
Write the information in the diary.
Start writing from the “baseline” and record three times a day at the exact times.
For instance, when you would typically eat meals. Take extra measurements if you feel a change in your health.
