Sounds like a possible false negative.

Retest and keep taking the supplements and sleeping. See if a doctor can prescribe any of the therapy to further help.

Some tests are only right 90% of the time on their negatives.

[Texas Eagle]

Prayers up for health and guidance. Is she within driving distance or do you have any family members who are?

[LukeL]

It is recommended that you test your pulse ox using your non dominant hand and then use your middle finger. Callouses can impede the reading and give a lower number.

The supplements to take:

Pinging. I don’t know other medical people here at FR, or don’t recall who they are.

[BeauBo]

Anything under 90% on the pulse oximeter is low. She should go to the hospital.

[GnuThere]

Can she contact her doctor or whoever’s on call?
If she’s short of breath she should get a chest X-ray.

[irishjuggler]

I had low numbers like that once when I was junked up with bronchitis. I don’t think you’re going to pass out at 89%, but it’s low. She needs to get to a doctor.

[HIDEK6]

Let Fauci test her. He’ll count her as two positives.

[Governor Dinwiddie]

I would wonder about the calibration of the tester and the battery level. There are a lot of cheap Chinese O₂ finger testers that aren't accurate.

If I had a question I'd drop by urgent care or the rescue squad and ask them to check it.
 

[Guenevere]

Pray!
I will pray too.
Pray for peace, give your worries to Him
Pray that you will hear from her.....soon even.
Sing a hymn.....seriously .....sing praises to Him in the middle of your trial
It will lift your spirits

Pray for her oxygen level to go up...
....they can vary......my husband’s fluctuate too.
Pray for peace.
Thank God

If she is testing herself while wearing nail polish it can mess up the reading

[Zeroisanumber1]

Either a false negative or she has another cardiovascular disease that's pushing her into dangerously low O2 levels. Contact a medical professional immediately.

Many insurance plans have a "Nurse Line" or something similar. I'd call them and ask for advice right away.

[HollyB]

She should go to the hospital regardless. There are other reasons such as low rbc’s or even a false negative. Either way she should be seen.

[Drago]

Have her try different fingers and take a few deep breaths to see if that boosts the reading. The $40’ish drug store pulse/oximeters probably aren’t the most accurate devices.

[JFoobar]

Less posting, more driving.

[Guenevere]

PS
Just the other day, after our walk, my husband had an 89
....but a few seconds later it was up to 92, and on

[Tacrolimus1mg]

The method they use for testing is not meant for diagnostics, but originally for research. PCR testing is unreliable in a diagnostic medium.

Honestly, with O2 of 90, that’s highly abnormal. I would call your doctor, or whoever is on call, and ask for advice.

If it were me, because I’m high-risk, I’d text my doc. If he told me to head to the ER, I would.
