guys i've already got mine, heres how to test of yours work

clip it in your finger, average reading should be about 96%
after that take a few deep breaths , you'll see the reading go up to 99%
after that hold your breath for 1min, you'll see the reading drop to 90% or below

How much cpap? Where you buy?

Adoi even in hospital its all about clinical signs and symptoms.

Its better if you watchout for shortness of breath, decreased effort tolerance (cepat penat), fever and such.

You tengok spo2 24jam nanti takut bodo je.

i heard if kena covid, some will not feel much effect but in actual your blood oxygen level goes low, and danger if below 91%.

thought want to keep one unit at home and found this quite cheap in shopee, any other reliable recommendation or comment?

or just use samsung phone saja?

According to this doctor, by the time your O2 rate is low, its too late already. Your lungs will try to keep up 100% O2 even in damaged condition until it really really cant.

Anyway better get Doctors opinion before purchase.
