Laboratory Yovuta: machulukitsidwe - ndichiyani?

Pang'ono fluctuation magazi mpweya machulukitsidwe mlingo angayambe munthu aliyense. Kwa kusanthula molondola kusintha chizindikiro ichi adzakhala olondola amathera miyezo ochepa. Kenako m'nkhani ife tikupeza chifukwa pali kusinthasintha mu njira iwo atathana ndi zinthu zofunikira nazo.

Kuchepetsa O ₂ m'magazi: Zoyambitsa

Magazi mpweya machulukitsidwe amapezeka mu mapapo. Ndiye, O ₂ ikuchitika kuti ziwalo ndi nawo hemoglobin. pawiri izi ndi zenizeni transporter mapuloteni. Umapezeka maselo ofiira - maselo ofiira. Malinga ndi kuchuluka kwa mpweya machulukitsidwe n'zotheka kudziwa kuchuluka kwa magazi, amene ali pano mu thupi mu boma omangidwa ndi oxygen. Choncho, mlingo machulukitsidwe ayenera kukhala mu osiyanasiyana 96-99%. Pamene ngati chizindikiro zayamba hemoglobin zonse kumangidwa ndi oxygen. Chifukwa malo-apansi ake akhoza kukhala matenda aakulu a dongosolo kupuma ndipo mtima. Mu magazi, magazi a ali kwambiri yafupika. Pankhani ya aggravation a mtima ndi mapapo matenda aakulu ndi anaonanso kuchepa mpweya magazi, choncho ndi bwino kukaonana ndi dokotala.

Chimfine, chimfine, SARS, chibayo, chifuwa bwanji mlingo afotokoze matenda aakulu. Pa kafukufukuyu m'pofunika kuganizira zinthu zina extraneous okhudza kuchepa mpweya machulukitsidwe mu magazi ndi kusintha magawo. Awa ndi lamulo la manja kapena zala kugwedeza, zozipakapaka msomali ndi kukhalapo kwa malankhulidwe mdima, kukhudzana mwachindunji. Zina mwa zinthu kuti zidziwike ngati otsika firiji ndi zinthu pafupi ndi cheza atomu, kuphatikizapo foni. Zonsezi kumabweretsa zolakwa miyezo ku matenda.

Machulukitsidwe - ndichiyani?

Iwo limanenedwa ngati boma la machulukitsidwe zakumwa mpweya. Machulukitsidwe mankhwala amatanthauza kuchuluka kwa mpweya magazi. chizindikiro ichi ndi chimodzi mwa zofunika kwambiri ndipo amaonetsetsa uziyenda wabwinobwino wa chamoyo. Magazi amanyamula mpweya zofunika uziyenda bwino ziwalo zonse. Kodi kudziwa magazi mpweya machulukitsidwe? Kodi izo?

kugunda Oximeter

Magazi mpweya machulukitsidwe anatsimikiza ndi Pankafunika zimachitika oximetry. chipangizo, amene ntchito mu nkhani iyi akutchedwa zimachitika oximeter. Kwa nthawi yoyamba njira imeneyi yakhala ikugwiritsidwa ntchito mu zipatala mu zofikira matenda akayakaya. A zimachitika oximeter wakhala alipo poyera chida Kupeza Vuto thanzi la munthu. Icho chinali kugwiritsidwa ntchito ngakhale panyumba. chipangizo ndi losavuta ntchito, kotero ntchito womwewo ena zizindikiro zofunika pamoyo, kuphatikizapo kugunda kwa mtima ndi mpweya machulukitsidwe. Kodi chipangizo ichi ndi mmene limagwirira ntchito?

Mfundo ntchito zipangizo

Kufalitsa ndi yambiri ya mpweya mu thupi ndi boma womangidwa kwa hemoglobin. Mavesi ikuchitika momasuka magazi, chimene chingathe kungolandira kuwala, ndipo chinthu china chilichonse. mfundo ntchito ya zimachitika oximeter ndi chiyani? Yoganizira zofunika kuti magazi zitsanzo zosankhidwazi. Monga mukudziwa, njirayi zosasangalatsa, ambiri sangakhoze kulekerera. Izi ndi zoona makamaka kwa ana. Iwo kovuta kuti n'chifukwa chake machulukitsidwe anatsimikiza kuti izi ndi zimene kufunika. Koma, mwamwayi, pulsoksometriya kumatha mosavuta. Kafukufuku amene anachitidwa kwathunthu sabweretsa chisoni, kudya ndi kwathunthu "yopanda magazi". Kunja kachipangizo amene olumikizidwa kwa chipangizo wapendekera ndi nsonga khutu la chala kapena ziwalo zina zotumphukira. chifukwa The kukonzedwa ndi purosesa ndi kuwonetsera Tingaone, mpweya machulukitsidwe yachibadwa kapena ayi.

Features

Komabe, pali angapo zina zabwino. Mu thupi la munthu pali awiri mitundu hemoglobin: wobwezeretsedwa ndi oxyhemoglobin. oxygenates otsiriza zimakhala. Kugunda oximeter Vuto kusiyanitsa mitundu awa a oxygen. The kachipangizo zotumphukira lili LEDs awiri. Tinachokera kwa munthu cheza kuwala kofiira kukhala timaganiza za 660 nm ndi mzake - infuraredi amene timaganiza ndi 910 nm ndi pamwamba. Ndi chifukwa cha mayamwidwe Phokoso awa, ndipo n'zotheka kudziwa mlingo wa oxyhemoglobin. kachipangizo zotumphukira amaperekedwa ndi photodetector, amene alandira matabwa kuwala. Amadutsa minofu ndi akutumiza mbendera chipika procedural. Lotsatira, chifukwa muyeso ndi chinaonekeranso pa chiwonetsero, ndipo apa n'zotheka kudziwa mpweya machulukitsidwe yachibadwa kapena kupatuka. The chenjezo chachiwiri ndi kuyamwa Kuwala kokha kwa magazi wolumikizira. Ichi ndi chifukwa umatha kusintha kachulukidwe ake, chinthu ichi mwachita molumikizana ndi kusintha magazi. Chifukwa cha zimenezi, wolumikizira kuwala linanena bungwe ranges kwambiri wamkulu. Kugunda Oximeter kusiyanitsa kuwala kudutsa izo kupyolera mtsempha wamagazi ndi.
