Pulse Oximeter ‘Detects’ a Pencil’s Heartbeat, Oxygen Levels

A pulse oximeter is a small electronic device that estimates the saturation of oxygen in a person’s blood. Most pulse oximeters also display the person’s pulse rate, displayed as “PR bpm” which means pulse rate at beats per minute, the unit of measure.

This is an important medical equipment used to check oxygen levels in the blood, especially because the number should be within the 95% to 100% range for a person to stay safe. Meanwhile, the normal resting heart rate for adults ranges from 60 to 100 bpm.

Since COVID-19 causes breathing problems that could lead to a lower oxygen saturation in a person’s body, sales for pulse oximeters have gone up. Not only are these medical devices used in hospitals, many individuals have also decided to buy one for their use at home.

But there are so many of these devices being sold in the market that a lot of counterfeiters have also used this opportunity to sell fake pulse oximeters. What’s sad is that there are actually a lot of people who bought the fake items from these suppliers, thinking that they were able to save a lot of money by buying these cheaper devices.

It turned out that these fake devices don’t even work properly! One person from Mumbai, India, recently shared a video of a pulse oximeter that’s absolutely fake because it detected a pencil’s heartbeat and oxygen levels! Tsk. Tsk.

This is how the Chinese are playing with our life I request all of you to stop using this Chinese oxymeter it shows heart beats an oxygen level of a wooden pencil…..boycott China,” Kushal Dhuri (@kushal_dhuri) angrily wrote.

He added, “In the name of medical equipment online and in the market, many unreliable Chinese goods are being sold. These cannot be trusted as they are playing with the lives of people. I would like to appeal to people to stop buying Chinese manufactured oxymeters (oximeters) as the one I bought shows the heartbeat and oxygen level of a pencil. Such an oxymeter (oximeter) can cost someone his/her life.
