Ọbara oxygen saturation (SpO2)

SPO2nwere ike gbarie n'ime ihe ndị a: "S" pụtara saturation, "P" pụtara pulse, na "O2" pụtara oxygen.Mkpụkpọ okwu a na-egosi ọnụọgụ oxygen nke etinyere na sel hemoglobin n'ime usoro mgbasa ọbara.Na nkenke, uru a na-ezo aka na ọnụọgụ oxygen nke mkpụrụ ndụ ọbara uhie na-ebu.Ntụle a na-egosi ịdị mma nke iku ume onye ọrịa yana arụmọrụ ọbara na-erugharị n'ahụ niile.A na-eji saturation oxygen mee ihe dị ka pasenti iji gosi nsonaazụ nke nha a.Nkezi ọgụgụ maka onye toro eto nwere ahụike bụ 96%.

97% saturation = 97% ikuku oxygen ele anya (nkịtị)

90% saturation = 60% ikuku ikuku oxygen (ihe egwu)

80% saturation = 45% ọbara oxygen akụkụ akụkụ (oke hypoxia)
