Probably not that useful. No way to know if it is accurate.
Started off OK but no software and it stopped being accurate in just months. I have no idea if it every was accurate now. I had to struggle with seller to get software and it does not go to this so no idea if I can recalibrate it. I seemed to be getting worse and worse and tonight it was saying I had a PulseOx of 80 when I was wide awake and fine. I compared it to another finger meter and I was fine. This item was giving out false data. $200 should last longer than 2 months.<br />Bad data might be worse than no data at all.
