Indlela yokubeka iliso kwi-oxygen saturation yegazi?
Impumlo okanye ibunzi linokubona ukugcwala kweoksijini egazini lomntu
Impumlo ivulekile kwaye ibhityile, nto leyo inceda ukuchonga ioksijini yegaziIntambo yolwandiso loluvo lwe-SpO2.Nangona kunjalo, iprobe ye-oxygen saturation yeempumlo iyabiza kakhulu kwaye inokusetyenziswa njengeprobe encedisayo.
Isikhundla sebunzi kunenzuzo ngakumbi kunezinye izikhundla ngenxa yokuba ayichaphazeli lula indawo ye-receptor kunye nokuhamba kwamalungu, kwaye kulula ukuyilungisa.Nangona kunjalo, ngenxa yokuba ibunzi libiza kakhulu, lidla ngokucetyiswa kwizigulana ezifuna umthambo.
Qaphela xa usebenzisa iintambo zokwandisa isivamvo se-spo2
1. Izikhonkwane zesigulane akufanele zibe zide kakhulu kwaye zingabi nazo naziphi na izikhonkwane, ukungcola okanye izikhonkwane.
2. Ukuba umnwe wesigulane uziva ungakhululekile emva kokubeka iliso kwi-oksijeni yegazi ixesha elide, omnye umnwe kufuneka utshintshwe ukujonga.
3. Ngethuba lenkqubo yokubeka iliso, ukuba isigulane kunye nabasebenzi bezonyango badibanisa kwaye badonsa i-spo2 probe kunye nocingo, ukuphazamiseka kuya kwenzeka.Kucetyiswa ukuba isigulana sihlale sizolile size sifunde ixabiso ngokuchanekileyo.
Ulwahlulo lokufumanisa ukugcwala kweoksijini yegazi
Indlela eqhelekileyo ye-electrochemical yokulinganisa ukugcwala kweoksijini isebenzisa aisivamvo se-Spo2 esilahlwayoukuqokelela kuqala igazi kumzimba womntu (elona liqhelekileyo lisetyenziselwa ukuqokelela igazi le-arterial), kwaye usebenzise i-analyzer yegesi yegazi kuhlalutyo lwe-electrochemical, kwaye ulinganise i-oksijini ye-arterial phakathi kwemizuzu embalwa Uxinzelelo (PaO2).Bala i-arterial oxygen saturation (SaO2).Ngenxa yokuba le ndlela idinga i-arterial puncture okanye intubation, iya kubangela intlungu kwisigulane kwaye ayikwazi ukubeka iliso ngokuqhubekayo.Ngoko ke, kunzima ukuba isigulane sifumane unyango kwimeko eyingozi.Inzuzo yendlela ye-electrochemical kukuba umphumo wokulinganisa uchanekile kwaye unokwethenjelwa, kodwa ukungahambi kakuhle kukuba kuyinkathazo kwaye ayikwazi ukubeka iliso ngokuqhubekayo.Yindlela yokulinganisa i-oxygen saturation yegazi.
Indlela ye-optical yindlela entsha yokulinganisa i-optical enqoba iintsilelo zendlela ye-electrochemical.Yindlela eqhubekayo yokulinganisa i-oksijini yegazi engapheliyo engasetyenziswa kumagumbi angxamisekileyo, amagumbi okusebenza, amagumbi okubuyisela kunye nezifundo zokulala.Umgaqo-siseko kukubona utshintsho kwigazi lokufunxa igazi kunye nokulinganisa ipesenti ye-oxyhemoglobin (HbO2) kwi-hemoglobin epheleleyo (Hb).Fumana i-SpO2.Inzuzo yale ndlela kukuba iyakwazi ukulinganisa ngokuqhubekayo umzimba womntu ngaphandle kokulimala, kwaye isixhobo silula kwaye kulula ukuyisebenzisa, ngoko siye satsala ingqalelo ngakumbi nangakumbi.Ukungalungi kukuba ukuchaneka kokulinganisa kuphantsi kunendlela ye-electrochemical, kwaye impazamo ebangelwa ixabiso eliphantsi le-oxygen yegazi likhulu.Indlebe oximeters, i-oximeters yobude obuninzikunye ne-pulse oximeters esanda kwaziswa sele ibonakala.Iphutha lokulinganisa i-pulse oximeter yamva nje inokulawulwa ngaphakathi kwe-1% ukuhlangabezana neemfuno zokusetyenziswa kweklinikhi.Nangona benganelisekanga ngandlel’ ithile, izibonelelo zabo zonyango ziye zamkelwa ngokubanzi.
