I-Oximetry: yintoni kunye namaxabiso aqhelekileyo okugcwala

Umxholo

• 1. I-Pulse oximetry (engangenisiyo)
• 2. I-Oximetry / iigesi zegazi (ezingenayo)
• Amaxabiso esiqhelo okugcwala
• Khathalela iziphumo ezichanekileyo

I-Oximetry luvavanyo olukuvumela ukuba ulinganise ukwanda kweoksijini yegazi, leyo yipesenti yeoksijini ethuthwa kwigazi. Olu vavanyo, olunokwenziwa esibhedlele okanye ekhaya nge-oximeter yokubetha, kubalulekile xa izifo ezonakalisa okanye eziphazamisa ukusebenza kwemiphunga, isifo sentliziyo okanye izifo ze-neurological, umzekelo, kurhanelwa.

Ngokubanzi, i-oximetry engaphezulu kwe-90% ibonisa i-oxygenation elungileyo yegazi, nangona kunjalo, kubalulekile ukuba ugqirha avavanye imeko nganye. Izinga le-oxygenation ephantsi yegazi linokubonisa isidingo sonyango esibhedlele ngeoksijini, kwaye inokubonisa imeko esongela ubomi ukuba ayilungiswa kakuhle. Qonda ukuba ziziphi iziphumo zokunqongophala kweoksijini egazini.

Zimbini iindlela zokulinganisa i-oxygen saturation:

1. I-Pulse oximetry (engangenisiyo)

Le yeyona ndlela isetyenziswayo ukulinganisa ukwanda kweoksijini, kuba ayisiyongxaki yokulinganisa i-oksijini ngesixhobo esincinci, esibizwa ngokuba yi-pulse oximeter, edibene nolusu, ihlala incam. umnwe.

Olona ncedo luphambili lweli nqanaba kukuba akuyomfuneko ukuba uqokelele igazi, uphephe ukulunywa. Ukongeza kwi-oximetry, esi sixhobo sinokukwazi ukulinganisa enye idatha ebalulekileyo, njengesixa sokubetha kwentliziyo kunye nenqanaba lokuphefumla, umzekelo.

• Ingaba isebenza kanjani: i-oximeter ye-pulse ine-sensor yokukhanya ethatha inani leoksijini edlula egazini phantsi kwendawo apho uvavanyo lwenziwa khona kwaye, kwimizuzwana embalwa, ibonisa ixabiso. Ezi zivamvo zithatha imilinganiselo ekhawulezileyo, yesiqhelo kwaye ziyilelwe ukuba zisetyenziswe kwiminwe, ezinzwaneni okanye endlebeni.

I-oximetry ye-pulse isetyenziswa kakhulu ngoogqirha nakwabanye abaqeqeshi bempilo ngexesha lovavanyo lweklinikhi, ngakumbi kwiimeko zezifo ezibangela ubunzima ekuphefumuleni, ezinje ngemiphunga, intliziyo kunye nezifo zemithambo-luvo, okanye nge-anesthesia, kodwa inokusetyenziselwa ukubeka esweni imeko yezempilo kwimeko apho losulelo lwe-coronavirus. I-oximeter inokuthengwa nakwiivenkile zonyango okanye ezibhedlele.

2. I-Oximetry / iigesi zegazi (ezingenayo)

Ngokungafaniyo ne-oximetry ye-pulse, uhlalutyo lwegesi yegazi yindlela engenayo yokulinganisa inqanaba leoksijini egazini, njengoko kusenziwa ngokuqokelela igazi kwisirinji, kwaye oku kuyimfuneko kwintonga yenaliti. Ngesi sizathu, olu hlobo loviwo alufane luqheleke kune-pulse oximetry.

Uncedo lweearterial gases zegazi lelona nyathelo lichanekileyo lokugcwalisa ioksijini egazini, ukongeza ekubeni nakho ukubonelela ngamanye amanyathelo abalulekileyo, njengesixa sekharbhon diokside, i-pH okanye isixa seasidi kunye ne-bicarbonate egazini, umzekelo.

• Ingaba isebenza kanjani: Kuyimfuneko ukwenza ingqokelela yegazi emva koko isampulu ithathwa ukuba ilinganiswe kwisixhobo esithile elebhu. Imithambo yegazi esetyenziselwa olu hlobo lokulinganisa yimithambo ye-radial, esihlahleni, okanye kwisini, esinqeni, kodwa ezinye zinokusetyenziswa.

Olu hlobo lokulinganisa luhlala lusetyenziswa kuphela kwiimeko apho isigulana sifuna ukubekwa esweni ngokuqhubekekayo okanye ngokuchanekileyo, exhaphake kakhulu kwiimeko ezinje ngotyando olukhulu, isifo sentliziyo, arrhythmias, usulelo ngokubanzi, utshintsho ngesiquphe kuxinzelelo lwegazi okanye iimeko zokusilela kokuphefumla, umzekelo. Funda ukuba yintoni ukusilela kokuphefumla kunye nendlela enokunciphisa ioksijini yegazi.

Amaxabiso esiqhelo okugcwala

Umntu ophilileyo, onomoya owaneleyo womzimba, uhlala ene-oxygen saturation ngaphezulu kwe-95%, nangona kunjalo, kuqhelekile ukuba kwiimeko ezinobulali, ezinje ngemikhuhlane okanye umkhuhlane, ukugcwala kuphakathi kwe-90 kunye ne-95%, ngaphandle kwesizathu sokukhathazeka.

Xa ukugcwala kufikelela kumaxabiso angaphantsi kwe-90%, inokubonisa ukuncitshiswa konikezelo lweoksijini emzimbeni ngenxa yesifo esibi kakhulu esikwaziyo ukunciphisa ukusebenza konaniselwano ngegesi phakathi kwemiphunga negazi, ezinje njenge-asthma, inyumoniya, i-emphysema, ukusilela kwentliziyo okanye izifo ze-neurological kunye nengxaki yeCovid-19, umzekelo.

Kwiigesi zegazi ezijikelezayo, ukongeza kumlinganiso we-oxygen saturation, uxinzelelo lwe-oksijini (Po2) nayo iyavavanywa, ekufuneka ibe phakathi kwe-80 kunye ne-100 mmHg.

Khathalela iziphumo ezichanekileyo

Kubaluleke kakhulu ukuba izixhobo ezilinganisa i-oxygen saturation zilungelelaniswe rhoqo, ukunqanda iziphumo eziguqulweyo. Ukongeza, xa usebenzisa i-oximeter yokubetha, ezinye iindlela zokuthintela ukutshintsha uviwo zibandakanya:

• Gwema ukusebenzisa i-enamel okanye izikhonkwane zobuxoki, njengoko ziguqula ukuhamba kwesivamvo sokukhanya;
• Gcina isandla sikhululekile kwaye ngezantsi kwenqanaba lentliziyo;
• Khusela isixhobo kwindawo eqaqambe kakhulu okanye enelanga;
• Qinisekisa ukuba isixhobo sibekwe ngokuchanekileyo.

Phambi kokwenza uvavanyo, ugqirha kufuneka aphande nezinye izifo ezinje ngeanemia okanye ukungahambi kakuhle kwegazi, ezinokuphazamisa umlinganiso weoksijini yegazi.
