Ngasekupheleni kwawo-1990, kwenziwa izifundo eziningana ukuze kuhlolwe ukunemba kwabangewona ochwepheshe, abaphenduli bokuqala, abezimo eziphuthumayo kanye nodokotela ngisho nokuhlola ukuba khona kwe-pulse kuphela.Kolunye ucwaningo, izinga lokuphumelela lokuqashelwa kokushaya kwenhliziyo laliphansi njenge-45%, kanti kolunye ucwaningo, odokotela abancane bachithe isilinganiso samasekhondi angu-18 ukuze babone ukushaya kwenhliziyo.
Kungenxa yalezi zizathu ukuthi ngokwezincomo ze-International Resuscitation Committee, i-British Resuscitation Committee kanye ne-American Heart Association yakhansela ukuhlolwa kwe-pulse evamile njengophawu lokuphila kusukela ekuqeqeshweni kosizo lokuqala olubuyekezwe ngo-2000.
Kodwa ukuhlola ukushaya kwenhliziyo kubaluleke ngempela, Njengazo zonke izimpawu ezibalulekile eziyisisekelo, ukwazi ukuthi izinga lokushaya kwenhliziyo kolimele lingaphakathi kwebanga elivamile kungasidlulisela ukwaziswa okubalulekile;
Uma ukushaya kwenhliziyo kwabalimele kungekho ngaphakathi kwala mabanga, kungasiholela ezinkingeni ezithile.Uma othile egijima, silindele ukuthi ukushaya kwenhliziyo yakhe kukhuphuke.Sifuna futhi ukuthi zishise, zibebomvu futhi ziphefumule ngokushesha.Uma zingakagijimanga, kodwa zishisa, zibomvu, ziphefumula futhi zishaya ngamandla, singase sibe nenkinga, okungase kubonise i-sepsis.Uma beyizisulu;ishayela elishisayo, elibomvu, elihamba kancane futhi eliqinile, lokhu kungase kubonise ukulimala kwekhanda kwangaphakathi.Uma belimele, bebanda, bephaphathekile futhi benenhliziyo esheshayo, bangase babe nokushaqeka kwe-hypovolemic.
Sizosebenzisa i-pulse oximeter:I-Pulse oximeteriyithuluzi elincane lokuxilonga elisetshenziswa kakhulu ukuhlonza ukugcwala komoyampilo wegazi kwabalimele, kodwa futhi lingabonisa ukushaya kwenhliziyo kwabalimele.Ngeyodwa yazo, asikho isidingo sokumosha isikhathi ukuze sifinyelele abalimele futhi sizwe ukushaya ngamandla.
Indlela ye-pulse oximetry ikala inani lomoya-mpilo othwalwa egazini njengephesenti.Sebenzisa i-pulse oximeter ukukala emunweni wakho.Lesi silinganiso sibizwa nge-Sp02 (i-peripheral oxygen saturation), futhi siyisilinganiso se-Sp02 (i-arterial oxygen saturation).
I-hemoglobin emangqamuzaneni abomvu egazi ithwala umoya-mpilo (inani elincane lincibilika egazini).Ingqamuzana ngalinye le-hemoglobin lingathwala amangqamuzana omoya-mpilo angu-4.Uma yonke i-hemoglobin yakho iboshelwe kuma-molecule e-oxygen amane, khona-ke igazi lakho "lizogcwala" umoya-mpilo, futhi i-SpO2 yakho izoba ngu-100%.
Abantu abaningi abanayo i-100% ye-oxygen saturation, ngakho-ke uhla lwama-95-99% lubhekwa njengento evamile.
Noma iyiphi inkomba engaphansi kuka-95% ingabonisa i-hypoxia-hypoxic oxygen izongena ezicutshini.
Ukuncipha kwe-SpO2 kuwuphawu oluthembeke kakhulu lwe-hypoxia yomuntu olimele;ukwanda kwezinga lokuphefumula kuhlobene ne-hypoxia, kodwa kunobufakazi bokuthi lokhu kuxhumana akuqinile ngokwanele (futhi kukhona ngisho nakubo bonke izimo) ukuze kube uphawu lwe-hypoxia.
Ii-pulse oximeteriyithuluzi elisheshayo lokuxilonga elikuvumela ukuthi ulinganise futhi uqaphe izinga le-oxygenation lomuntu olimele.Ukwazi ukuthi i-Sp02 elimele ingakusiza futhi ukuthi unikeze inani elifanele le-oxygen ngaphakathi kwebanga lamakhono.
Ngisho noma ukugcwala komoyampilo egazini kungaphakathi kwebanga elivamile, i-SpO2 yehliswa ngo-3% noma ngaphezulu, okuyinkomba yokuhlolwa okuphelele kwesiguli (kanye nesignali ye-oximeter), ngoba lokhu kungase kube ubufakazi bokuqala besifo esibucayi.
