SPO2inogona kupatsanurwa kuita zvikamu zvinotevera: “S” zvinoreva kuzara, “P” zvinoreva kupomba, uye “O2” zvinoreva oxygen.Iyi acronym inoyera huwandu hweokisijeni yakanamatira kumasero ehemoglobin muhurongwa hwekutenderera kweropa.Muchidimbu, kukosha uku kunoreva huwandu hweokisijeni inotakurwa nemasero matsvuku eropa.Chiyero ichi chinoratidza kushanda kwekufema kwemurwere uye kushanda kweropa kuyerera mumuviri wese.Iyo oxygen saturation inoshandiswa sechikamu kuratidza mhedzisiro yechiyero ichi.Avhareji yekuverenga kumunhu mukuru ane hutano hwakanaka i96%.
Kuzadzwa kweokisijeni muropa kunoyerwa uchishandisa pulse oximeter, iyo inosanganisira komputa ine monitor uye zvigunwe cuffs.Mibhedha yeminwe inogona kusungirirwa pazvigunwe zvemurwere, zvigunwe, mhino kana nzeve.Monitor inozoratidza kuverenga kunoratidza huwandu hweokisijeni muropa remurwere.Izvi zvinoitwa uchishandisa masaisai anodudzirwa anooneka uye masaini anonzwika, ayo anowirirana nekupuruzira kwemurwere.Sezvo huwandu hweokisijeni muropa hunodonha, simba rechiratidzo rinoderera.Iyo yekutarisa inoratidzawo kurova kwemoyo uye ine alarm, kana iyo pulse ikanyanya kukurumidza / inononoka uye saturation yakanyanya / yakaderera, chiratidzo chealarm chinopihwa.
Theropa okisijeni saturation mudziyoinoyera ropa reokisijeni uye hypoxic ropa.Mavhiri maviri akasiyana anoshandiswa kuyera aya marudzi maviri eropa akasiyana: tsvuku uye infrared frequencies.Iyi nzira inonzi spectrophotometry.Iyo tsvuku frequency inoshandiswa kuyera desaturated hemoglobin, uye infrared frequency inoshandiswa kuyera ropa rine mweya.Kana ikaratidza kunyura kukuru mubhendi re infrared, izvi zvinoratidza kuzara kwepamusoro.Sezvineiwo, kana iyo yakanyanya kunyura inoratidzwa mubhendi dzvuku, izvi zvinoratidza kuderera kwakadzika.
Chiedza chinoparidzirwa kuburikidza nemunwe, uye maranzi anotapurirwa anotariswa neanogamuchira.Chimwe chechiedza ichi chinotorwa nematishu neropa, uye kana tsinga dzazara neropa, kutorwa kunowedzera.Saizvozvowo, kana tsinga dzisina chinhu, chiyero chekutora chinodonha.Nekuti mukushandisa uku, iyo chete shanduko ndeyekupuruzira kuyerera, iyo static chikamu (kureva ganda uye tishu) inogona kubviswa kubva pakuverenga.Naizvozvo, uchishandisa mawavelength maviri echiedza akaunganidzwa mukuyera, iyo pulse oximeter inoverengera kuzara kweiyo oxygenated hemoglobin.
97% saturation = 97% oxygen partial pressure (yakajairika)
90% saturation = 60% oxygen partial pressure (ine ngozi)
80% saturation = 45% ropa reoxygen partial pressure (yakanyanya hypoxia)
