Dh has a slight cough and snotty cold - he's tested negative on LFTs throughout the week. He's generally fine, worked throughout, a bit tired. I tend to worry about these things.
I bought a pulse oximeter from amazon today and just tested him a few times over the evening - his levels are between 92 and 95 at best, even with deep breaths. Mine are 98 and 99 so I don't think it's faulty.
Should I be concerned and trying to get him some help?
