Tests Laboratory: Gcwalisa - ntoni na?

nokuya phambili kancinane kwinqanaba Ukwanda ioksijini yegazi angenzeka wonke umntu. Kuba uhlalutyo oluchanekileyo ngakumbi na utshintsho kwesi salathisi iza kuba echanekileyo ukuchitha imilinganiselo ezimbalwa. Kamva kweli nqaku sifumanisa kutheni kukho ukuhla ngendlela iyalungiswa oko kuyimfuneko ukulawula kubo.

Ukunciphisa O ₂ egazini: Oonobangela

Blood oksijini Ukwanda kwenzeka emiphungeni. Emva koko, O ₂ kusiwa amalungu kunye nxaxheba mpilo. Le ephindeneyo iproteni umthuthi ethile. Efunyanwa kulo iiseli ezibomvu - iiseli ezibomvu. Ngokutsho umgangatho oxygen Ukwanda kunokwenzeka ukumisela isixa mpilo, akhoyo emzimbeni kwi imeko yento mpilo. Ngokusesikweni, inqanaba Ukwanda kufuneka kuluhlu 96-99%. Xa Isalathisi enjalo kakhulu yonke haemoglobin ebotshiwe mpilo. Isizathu sokuba ukwehlisela kwayo abe izifo kakhulu kwinkqubo bokuphefumla sentliziyo. Xa igazi, athwala liyehla kakhulu. Kwimeko ukuqhubela bezifo zizifo zentliziyo nemiphunga nawo wabona ukuhla ioksijini egazini, ngoko kuyacetyiswa ukuba udibane nogqirha.

Idalwa, umkhuhlane, SARS, inyumoniya, iphika esinganyangekiyo kuchaphazela isantya kwaye ingxelo ukugula kakhulu. Ngexesha lovavanyo kuyimfuneko ukuze bayithathele ingqalelo eminye imibandela nendaba echaphazela ukuhla oksijini Ukwanda egazini kunye nokutshintsha parameters. Ezi isindululo izandla okanye iminwe lafa, nail manicure kunye nobukho abanzi ezimnyama, ukuba sesichengeni ngqo. Phakathi imiba ukuba kuqatshelwe njenge lobushushu igumbi eliphantsi kunye nezinto olusondeleyo radiation magnetic, kuquka cell phone. Konke oku kukhokelela iimpazamo imilinganiselo luxilongo.

Ukwanda - ntoni na?

Oku kuchazwa imeko Ukwanda lulwelo igesi. Ukwanda amayeza ibhekisa ipesenti ioksijini egazini. Esi salathisi yenye yezinto ezibalulekileyo kwaye iqinisekisa eqhelekileyo yokusebenza eziphilayo. Igazi ithwala oxygen ezifunekayo ukusebenza eyiyo onke amalungu. Indlela ukuba yeyiphi ioksijini saturation igazi? Oko kuya kunika?

Pulse Oximeter

Blood oxygen Ukwanda ixhomekeke indlela ekuthiwa ukubetha oximetry. Isixhobo, esetyenziswa kule meko kuthiwa oximeter ukubetha. Kuba okokuqala le ndlela iye yasetyenziswa kwizibhedlele neeyunithi labagula kakhulu. A oximeter ukubetha iye sisixhobo ekhoyo esidlangalaleni ukuba zokufumanis impilo yabantu. Kuye ezisetyenziswa kweli khaya. Isixhobo kulula ukuyisebenzisa, ngoko besebenzisa kulinganiselwa ezinye iimpawu ubomi ezibalulekileyo, kuquka izinga lentliziyo kunye neoksijini kufumaneka bantu. Yintoni na le isixhobo esisebenza ngayo?

Umgaqo nokusebenza kwezixhobo

Ukubolekisa imali eninzi oksijini emzimbeni sikwimo bekhonkxiwe mpilo. Inxalenye eseleyo iqhutywa ngokukhululekileyo ngegazi, ezinako iginya ukukhanya, kunye nayiphi na enye into. Yintoni na umgaqo osebenza ngayo oximeter ukubetha? Ukuba uhlalutyo eziyimfuneko ukwenza isampulu yegazi. Njengoko usazi, le nkqubo mnandi, abaninzi ungenako ukubathwala. Oku kuyinyaniso ngakumbi abantwana. Kunzima kakhulu ukuba bachaze ukuba kutheni le Ukwanda umiselwa ukuba le nto imfuneko. Kodwa, yona, pulsoksometriya akubikho loo inkathazo. Uhlolisiso olwenziwe yalula ngokupheleleyo, ngok ngokupheleleyo "kwegazi". isivamvo lwangaphandle oludityaniswe kwisixhobo osimelela endlebeni incam yomnwe okanye namanye amalungu peripheral. Isiphumo kusingathwa yi iprosesa kunye nesiboniso zingabonakala, lo Ukwanda oxygen eqhelekileyo okanye hayi.

iimpawu

Nangona kunjalo, kukho isibini kujonge izinto. Emzimbeni womntu kukho ezimbini iindidi mpilo: ebuyiselweyo oxyhemoglobin. oxygenates yokugqibela emzimbeni. ukubetha oximeter Umngeni ukwahlula ezi ntlobo ze-oksijini. Le woluvo neuropathy iqulethe LED ezimbini. Sisuka kwimitha omnye ebomvu ukukhanya ukuba ngamaza 660 NM ukusuka kwenye - infrared ogama kwamaza ngu 910 NM nangaphezulu. Kungenxa kukufakwa ezi intlokoma, kwaye kunokwenzeka ukuba ukuqinisekisa inqanaba oxyhemoglobin. isivamvo neuropathy inesixhobo photodetector, yona efumana iintsika ukukhanya. Baya kucanda nyama kwaye ithumela umqondiso kwiibloko zenkqubo. Okulandelayo, isiphumo wemilinganiso aveliswa kwidispleyi, yaye nantsi kunokwenzeka ukumisela Ukwanda oxygen eqhelekileyo okanye kutenxa kokumiselweyo. Le caveat yesibini ukufunxa ukukhanya kuphela egazini yodidi oluphezulu. Oku kungenxa yokuba ekwazi ngayo ukutshintsha mninzi layo, oku kwenziwa kubanjiswene kunye notshintsho uxinzelelo lwegazi. Ngenxa yoko, emithanjeni output ukukhanya parameter kakhulu ngakumbi. Pulse Oximeter ukwahlula ukukhanya ngokugqithisa umthambo.
