Over the past few years, pulse oximeters have become a household item for many. These little devices, which measure your blood oxygen levels, became particularly popular during the COVID-19 pandemic when understanding respiratory health became essential. But now that the world has adjusted, you might be wondering: Do I still need a pulse oximeter?
What Exactly Is a Pulse Oximeter?
A pulse oximeter is a small, clip-like device that measures the oxygen saturation in your blood (SpO2) and your pulse rate. By shining light through your skin, it can determine how much oxygen your blood is carrying. Healthy oxygen levels generally range between 95-100%, and levels below 90% can be a sign of concern.
Fun Fact: Pulse Oximeters Aren’t That New!
Although these devices became widely used during the pandemic, pulse oximeters were invented in the 1970s by Japanese scientist, Dr. Takuo Aoyagi. His work revolutionized healthcare by making it easier to monitor oxygen levels in patients, especially in critical care and surgery. Now, even home health devices carry this technology!
Historical Context: The Pandemic Surge
During the height of the COVID-19 pandemic, pulse oximeters flew off the shelves as people sought a way to monitor their oxygen levels at home. With the virus often affecting breathing, individuals used these devices to detect early signs of a decline in oxygen saturation, especially if they were isolating or unable to access medical care right away.
Do You Still Need One?
As we return to a sense of normalcy, it’s worth considering whether you still need a pulse oximeter. For most people, if you’re in good health and not experiencing respiratory issues, a pulse oximeter might not be necessary. However, if you have chronic respiratory conditions like asthma or COPD, or if you're recovering from a severe illness, having one on hand can still be useful.
Should You Keep It Around?
Ultimately, whether you keep a pulse oximeter in your home depends on your personal health needs. For general well-being, they may not be necessary—but for those with underlying health conditions or a history of respiratory problems, it’s always a good idea to have one just in case. They’re quick, non-invasive, and could provide peace of mind during a flare-up or illness.
In Conclusion
The pulse oximeter isn’t just a passing trend. It’s a valuable tool for certain health conditions and situations, but it’s not essential for everyone. If you’re healthy, it might not be something you use daily, but it can certainly still be a helpful gadget to have in your health toolkit.
