Hello, this is Director Cho Young-min.

A new device has arrived at Anz!

This is a ring-type pulse oximeter.

Until now, oxygen saturation has mostly been measured with a clip that attaches to the fingertip.

Because of this,

especially for women with nail polish, pedicures, or gel nails,

you have probably been told many times to remove one or two nails before visiting the dermatology clinic.

In fact, if the nails are not removed, oxygen saturation sometimes cannot be measured,

so you may have experienced the frustrating situation of having to remove a nail you paid a lot for.

But now you don't need to do that!!!!

A device that can measure oxygen saturation just by wearing it like a ring

has arrived at Anz :)

Ring type pulse oximeter

The device is called ACRO-1.

Beyond the difference in shape from the devices used before,

since there is no connected cable,

it has the advantage that oxygen saturation is measured continuously even if you move during sleep anesthesia.

With the existing devices, if you moved, they would slip off the fingertip, so you had to wait to be re-measured.

Since this is good news, I am posting right after confirming that it works well, one week after it arrived!

I hope this good news reaches many people.

Frequently Asked Questions

Can oxygen saturation be measured with gel nails on?

Yes. The ring-type pulse oximeter ACRO-1 is described as being measurable without removing gel nails, simply by wearing it like a ring.

How is the ring-type pulse oximeter different from existing devices?

Unlike the conventional method of clipping onto the fingertip, the ring type is simply worn like a ring. It is also highlighted for having no connecting cable.

Can oxygen saturation still be measured during sleep anesthesia if I move?

Yes. Because the ring-type device has no connecting cable, it is said to measure oxygen saturation continuously even when you move during sleep anesthesia. With existing devices, movement could cause the clip to slip off the fingertip, requiring a wait for re-measurement.

What is the name of the newly introduced pulse oximeter at Anz?

The newly arrived ring-type pulse oximeter at Anz is called ACRO-1. The clinic says it posted the news after confirming normal operation one week after the device arrived.

Why did nails have to be removed for existing fingertip monitors?

Fingertip-clip devices sometimes cannot measure oxygen saturation unless the nail is removed. That is why many people have been advised to remove one or two nails before visiting the dermatology clinic.
