Ukugcwala komoyampilo okuvamile kungama-97-100%, futhi asebekhulile ngokuvamile banamazinga aphansi okugcwala komoyampilo kunabancane.Isibonelo, umuntu oneminyaka engaphezu kwengu-70 ubudala angase abe nezinga lokugcwala komoyampilo cishe elingama-95%, okuyizinga elamukelekayo.
Kubalulekile ukuqaphela ukuthi izinga lokugcwala komoyampilo lingahluka kakhulu kuye ngempilo yomuntu.Ngakho-ke, kubalulekile ukuqonda ukufundwa okuyisisekelo kanye ne-physiology engaphansi ehlotshaniswa nezimo ezithile ukuze kulandelwe amazinga okugcwala komoyampilo kanye nezinguquko kulawa mazinga.
Abantu abakhuluphele noma abahlushwa izifo zamaphaphu nezenhliziyo nemithambo yegazi, i-emphysema, isifo samaphaphu esingamahlalakhona, isifo senhliziyo esizalwa nabo, kanye nesifo sokuphelelwa umoya ngenxa yokulala bavame ukuba namazinga aphansi okugcwala komoyampilo.Ukubhema kuthinta ukunemba kwe-pulse oximetry, lapho i-SpO2 iphansi noma iphakeme ngokungeyikho, kuye ngokuthi ingabe kukhona i-hypercapnia.Nge-hypercapnia, kunzima nge-pulse oximeter ukuhlukanisa phakathi komoyampilo osegazini kanye ne-carbon monoxide (okubangelwa ukubhema).Uma ukhuluma, ukugcwala komoyampilo egazini kungase kwehle kancane.I-blood saturation ye-anemia yeziguli ingase ihlale ijwayelekile (isibonelo, i-97% noma ngaphezulu).Kodwa-ke, lokhu kungase kungasho ukuthi kukhona umoya-mpilo owanele, ngoba i-hemoglobin kubantu abane-anemia ayanele ukuthwala umoya-mpilo owanele.Ukungatholakali komoyampilo okwanele ngesikhathi semisebenzi kungase kubonakale kakhulu ezigulini ezine-anemia.
Amazinga angalungile we-hypoxic saturation angase ahlobane ne-hypothermia, ukwehla kokugcwala kwegazi okuzungezile, nokubanda kwamaphethelo.Kulezi zimo, i-earlobe pulse oximeter noma i-arterial blood gas izohlinzeka ngamaleveli anembe kakhudlwana wokugcwala komoyampilo.Kodwa-ke, amagesi egazi emithanjeni ngokuvamile asetshenziswa kuphela ekunakekelweni okukhulu noma ezimeni eziphuthumayo.
Eqinisweni, uhla lwe-SpO2 amakhasimende amaningi avame ukulamukela luyi-92-100%.Abanye ochwepheshe batusa ukuthi amazinga e-SpO2 okungenani angu-90% angavimbela ukulimala kwezicubu ze-hypoxic futhi aqinisekise ukuphepha komsebenzisi.
