Izinto eziluncedo zePulse Oximeter

I-Pulse oximetry ilungele ngokukodwa umlinganiselo oqhubekayo ongapheliyo we-blood saturation.Ngokwahlukileyo, amanqanaba erhasi yegazi ngenye indlela kufuneka amiselwe kwilabhoratri kwisampulu yegazi elitsaliweyo.I-Pulse oximetry iluncedo kuyo nayiphi na indawo apho i-oxygenation yesigulane ingazinzile, kubandakanywa ukunakekelwa okunzulu, ukusebenza, ukubuyisela, iimeko eziphuthumayo kunye nezibhedlele zesibhedlele, abaqhubi beenqwelo-moya ezingabonakaliyo, ukuvavanya nayiphi na i-oxygenation yesigulane, kunye nokugqiba ukusebenza okanye imfuno ye-oksijeni eyongezelelweyo. .Nangona i-pulse oximeter isetyenziselwa ukubeka iliso kwi-oxygenation, ayikwazi ukumisela i-metabolism ye-oksijini, okanye inani le-oksijini esetyenziswa sisigulane.Ngenxa yale njongo, kuyimfuneko ukulinganisa amanqanaba e-carbon dioxide (CO2).Kusenokwenzeka ukuba isenokusetyenziswa ukufumanisa izinto ezingaqhelekanga ekuphuhliseni umoya.Nangona kunjalo, ukusetyenziswa kwe-pulse oximeter ukubona i-hypoventilation iphazamiseka ngokusetyenziswa kwe-oksijeni eyongezelelweyo, njengoko kuphela xa izigulane ziphefumula umoya wegumbi ukuba ukungaqhelekanga kumsebenzi wokuphefumula kunokubonwa ngokuthembekileyo ngokusetyenziswa kwayo.Ngoko ke, ukulawulwa kwesiqhelo kwe-oksijeni eyongezelelweyo kunokungafuneki ukuba isigulane siyakwazi ukugcina i-oxygen eyaneleyo emoyeni wegumbi, kuba kunokubangela ukuba i-hypoventilation ingabonakali.

Ngenxa yokulula kwabo ukusetyenziswa kunye nokukwazi ukubonelela ngokuqhubekayo kunye nokukhawuleza kwexabiso le-oksijeni, i-pulse oximeters ibaluleke kakhulu kwiyeza likaxakeka kwaye ziluncedo kakhulu kwizigulane ezineengxaki zokuphefumla okanye zenhliziyo, ngakumbi i-COPD, okanye ukuxilongwa kokuphazamiseka kokulala. njenge-apnea kunye ne-hyopnea.Kwizigulane ezine-obstructive sleep apnea, ukufundwa kwe-pulse oximetry kuya kuba kuluhlu lwama-70% 90% ixesha elininzi elichithwe ukuzama ukulala.

I-pulse oximeters ephathwayo esebenza ngebhetri iluncedo kubaqhubi abasebenza kwinqwelo-moya engacinezelekanga ngaphezu kwe-10,000 yeenyawo (3,000 m) okanye i-12,500 yeenyawo (3,800 m) e-US apho ioksijini eyongezelelweyo ifuneka khona.Ii-oximeter eziphathwayo zepulse zikwaluncedo kubakhweli beentaba kunye neembaleki ezinamaqondo eoksijini anokwehla kwiindawo eziphakamileyo okanye ngokuzilolonga.Ezinye ii-pulse oximeters eziphathwayo zisebenzisa i-sofware ebonisa ioksijini yegazi lesigulana kunye ne-pulse, esebenza njengesikhumbuzo sokujonga amanqanaba eoksijini egazini.

Ukuqhubela phambili koqhagamshelwano kwenze ukuba izigulane zibe ne-blood saturation ye-oksijini ngokuqhubekayo ngaphandle koqhagamshelo olunentambo kwi-monitor yasesibhedlele, ngaphandle kokuncama ukuhamba kwedatha yesigulana ebuyela kwiimonitha ezisecaleni kwebhedi kunye neenkqubo ezisembindini zokukhusela isigulane.

Kwizigulana ezine-COVID-19, i-pulse oximetry inceda ekubhaqweni kwangoko kwe-hypoxia ethe cwaka, apho abaguli basajongeka kwaye baziva bekhululekile, kodwa i-SpO2 yabo iphantsi ngokuyingozi.Oku kwenzeka kwizigulana nokuba kusesibhedlele okanye ekhaya.I-Low SpO2 inokubonisa inyumoniya enxulumene ne-COVID-19, efuna isixhobo sokuphefumla.
