SpO2 na-anọchi anya saturation nke ikuku oxygen dị n'akụkụ, atụmatụ nke ọnụọgụ oxygen dị n'ọbara.Kpọmkwem, ọ bụ pasentị nke hemoglobin oxygenated (haemoglobin nwere oxygen) ma e jiri ya tụnyere mkpokọta hemoglobin dị n'ọbara (haemoglobin oxygenated na nke na-abụghị oxygen).
SpO2 bụ atụmatụ nke saturation oxygen na akwara akwara, ma ọ bụ SaO2, nke na-ezo aka na ọnụọgụ hemoglobin oxygenated n'ime ọbara.
Hemoglobin bụ protein nke na-ebu oxygen n'ime ọbara.A na-achọta ya n'ime mkpụrụ ndụ ọbara uhie ma nye ha agba uhie.
