Some Important Facts About Pulse Oximetry

What is Pulse Oximetry?

Pulse oximetry measures the blood vessel oxygen saturation quickly and handily. Although a few clinicians contend that pulse oximetry is a diagnostic test, it is viewed as the fifth vital sign, not an actual sign, since it requires special instrumentation. Estimation of oxygen saturation is basically the same as the other essential signs, for example, temperature and blood pressure, and requires a pulse oximeter.

Does the Covid Pandemic Mean You Need One?

Pulse oximeters are generally bought for home use by individuals who need to screen their oxygen supply, especially patients with ongoing lung conditions, such as COPD, individuals living at high altitudes, or athletes. Not long after the pandemic started, however, the simple-to-use gadgets began being promoted as a way to measure serious complications from Covid-19, the sickness the virus causes. Especially, lowered blood saturation levels of oxygen.

The explanation for why there is such extraordinary interest in pulse oximeters currently is that the coronavirus has a genuinely massive impact on the body’s capacity to oxygenate, usually not matching with how the patient feels. Though patients aren’t particularly out of breath, their low blood oxygen levels may show they are close to an emergency.

For Medical Use or Not for Medical Use?

The FDA counts pulse oximeters as clinical gadgets that require a prescription. To acquire FDA labeling for “clinical use,” the makers should present their devices for thorough human volunteer testing. Precise pulse oximeters use correction factors dependent on the in vivo correlation of blood hemoglobin oxygen saturation from direct measurement of arterial blood gases with what the pulse oximeter acquires over a broad scope of oxygen saturations.

What May Make Pulse Oximeter Readings Less Precise?

Pulse oximeters can have dishonestly low readings if an individual has circulatory issues with poor blood flow to the limbs—for example, intrinsic vascular disease, freezing hands, or Raynaud’s phenomenon. Plus, fake nails or dark nail polish can twist the readings. We always suggest that everyone measure at least one finger for every hand to verify the number.

Conclusion

If you can’t get a pulse oximeter immediately, you can definitely get one that can be delivered in under a month. If you become ill and don’t have a home pulse oximeter, don’t worry. The vast majority do fine without them. Plus, you can definitely get one from a neighbor or friend since they are easily cleaned or consult your physician about getting your oxygen levels checked at a facility.
