Here’s how to use the pulse oximeter and what it actually does

With this current global pandemic, it’s best to be careful and have all the necessary things to keep you safe. Or at least, able to help alert you when things go bad.

Introducing three devices: Pulse Oximeter, Blood Pressure Monitor and Thermometer. These are very important tools that will help monitor the state of oxygen in the blood (spo2), pulse rate (pulse rate), blood pressure, and body temperature.


Therefore, with these three tools, you and your health care provider can know your health status more accurately. Early detection and immediate action can be taken before it is too late.

So for the pulse oximeter, it is meant to work as a tool to measure the level of oxygen in your body and your heart rate.

Measurements and readings should be recorded 3 times a day and should be done at the same time each day. For example 3 times a day according to mealtimes.


Take additional measurements if you feel a change in your health.

  • Remove nail dye/fake nails and warm hands by rubbing both palms if it feels cold.
  • Rest for at least 5 minutes before taking the measurement.
  • Place your hands on your chest at heart level and keep your hands at that level.
  • Turn on the Pulse Oximeter and place it on the middle finger or index finger on the hand that is on the chest.
  • Maintain your hand position with the Pulse Oximeter for at least 1 minute or until the reading is stable.
  • Only record the highest reading if the reading does not change for 5 seconds.
  • Make sure each measurement is done carefully.

You are advised to seek treatment immediately if the oxygen level is less than 95%. Normal oxygen levels are between 95% – 99% and normal heart rates are between 50 – 90 per minute.
