100.33% නෑ. හමේ පාට අනුව වෙනස් වෙන්න පුළුවන්. බ්රෑන්ඩ් එක අනුවත් වෙනස් වෙන්න පුළුවන්. පරණ එකකට වඩා අළුතින් ආපු එකක නිරවද්යතාවය වැඩි වෙන්න පුළුවන්.
කොහොම උනත් දළ අදහසක් ගන්න පුළුවන් නිසා මොකක් හරි එකක් අරන් තියාගන්න.

1. SPO₂ ≥ 94% with no emergency signs (chest pain, dyspnoea, shortness of breath, altered mental status)- normal reading. Continue monitoring at home
2. SP0₂ ≤ 94%- patient requires hospitalisation for monitoring and further management. Arrange to transfer the patient to a designated treatment facility.
3. SP0₂ ≤ 90% is a medical emergency and requires referral to a health facility with an intensive care unit or high dependency unit.

There are two categories of pulse oximeters: prescription use and over-the-counter (OTC).
- Prescription oximeters are reviewed by the FDA, receive 510(k) clearance, and are available only with a prescription. The FDA requires that these pulse oximeters undergo clinical testing to confirm their accuracy. They are most often used in hospitals and doctors’ offices, although they may sometimes be prescribed for home use.
- Over-the-counter (OTC) oximeters are sold directly to consumers in stores or online and include smart phone apps developed for the purpose of estimating oxygen saturation. Use of OTC oximeters has increased as a result of the COVID-19 pandemic. These products are sold as either general wellness or sporting/aviation products that are not intended for medical purposes, so they do not undergo FDA review. OTC oximeters are not cleared by the FDA and should not be used for medical purposes.

These oximeters work by using an LED that emits two or more wavelengths and a photodetector which measures the difference light absorption in oxygenated or deoxygenated blood.
The cheaper ones are only accurate above 93% SpO2. Also they have an issue with the brown skin with false readings. The accuracy deteriorates with progressive hypoxaemia. A measurement of <93% on the portable device is cause for serious concern.
Here's the FDA take on their approved oximeters..... There are FDA approved oximeters for home use. Then there are medical grade oximeters.
"However, real-world accuracy may differ from accuracy in the lab setting. While reported accuracy is an average of all patients in the test sample, there are individual variations among patients. The SpO2 reading should always be considered an estimate of oxygen saturation. For example, if an FDA-cleared pulse oximeter reads 90%, then the true oxygen saturation in the blood is generally between 86-94%. Pulse oximeter accuracy is highest at saturations of 90-100%, intermediate at 80-90%, and lowest below 80%. Due to accuracy limitations at the individual level, SpO2 provides more utility for trends over time instead of absolute thresholds. Additionally, the FDA only reviews the accuracy of prescription use oximeters, not OTC oximeters meant for general wellness or sporting/aviation purposes."

PS: I have a Masimo MightySAT which is hospital grade and fairly accurate - The Masimo uses their SET technology (signal processing) to estimate the values.
There's certainly handy in having one, but you need to know it's capabilities and limitations.

- Do not rely only on a pulse oximeter to assess your health condition or oxygen level.
