Lub tshuab pa pulse yog ib qho kev kho mob uas ceev faj soj ntsuam cov pa taws ntawm cov neeg mob cov ntshav (as opposed to ntsuas cov pa ntawm cov ntshav mus kuaj) thiab cov kev hloov hauv cov ntshav ntim rau hauv daim tawv nqaij, ua tus photoplethysmogram.
Lub plhaub ntswj oximeter tiag tiag yog nruab nrab ntawm txoj kev saib xyuas kev kho mob, vim hais tias nws muab peb txoj kev txhim kho, yooj yim, thiab tsis mob siab los txiav txim seb cov pa oxygen nyob hauv cov ntshav zoo li cas. Peb muaj lwm txoj hau kev ua ntej (thiab tseem muaj lawv), tab sis lawv xav tau ib rab koob rau hauv cov hlab ntsha, feem ntau qhov radial artery uas koj hnov koj cov mem tes hauv koj lub dab teg.
Qhov tshaj plaws lub tshuab ntsuas, oxygen saturation, yog qhov sib npaug (feem pua) ntawm cov hemoglobin hauv cov ntshav liab uas nqa cov pa oxygen. Peb cov qe ntshav liab kub hnyiab tag nrho ntawm cov protein uas hu ua hemoglobin, uas yog tus cab kuj rau cov pa oxygen. Cov qe ntshav liab tsuas muaj ib txoj hauj lwm loj - khaws cov pa oxygen hauv lub ntsws, nqa mus rau lub cev uas xav tau, thiab muab pov tseg. Muaj ntau txoj kev uas peb cov ntshav khiav yog zoo li tsheb ciav hlau nrog txhua lub qe ntshav liab ua ib qho hlua ntawm lub tsheb ntev. Lub tsheb mus ncig thiab hloov ua lawv txoj hauj lwm, nrog rau txhua lub qe ntshav liab nyob ob peb lub hlis ua ntej yuav hloov nrog ib tug tshiab.
Cov pa roj carbon nrab yog nruab nrab ntawm cov tsheb hauv lub tsheb uas muaj cov pa oxygen. Feem ntau, thaum lub tsheb ciav hlau tawm hauv cov ntsws, nws muaj tsawg kawg yog 95%. Thaum nws rov los khaws lwm lub nra, nws tseem qee yam qis tshaj 70%. Qhov no muab peb lub cev nrog ib qho tseem ceeb ntawm kev ua yuam kev, qee qhov kev npaj ntawm cov pa oxygen. Qhov tseeb, yog tias lub tsheb ciav hlau rov qab rau lub ntsws, piv txwv, tsuas yog 40% tau sau, qhov no yog cov pov thawj ntawm cov teeb meem loj vim tias cov khoom siv tau siv. Lub tshuab pulse, lub teeb rau ntawm koj tus me nyuam tus ntiv tes, ntsuas kev mob ntawm cov ntshav tawm hauv lub ntsws.
Lub nplhaib oximetry yog cov cuab yeej zoo. Kuv nco qab ntsoov thaum cov khoom siv los ua, vim kuv tau kawm nyob rau hauv ib qho era thaum peb tsis muaj lawv. Qee zaum peb tus thawj zaug kos npe tias tus menyuam yuav xav tau cov pa oxygen ntxiv thaum lawv pib tig dusky xim, uas tsis tshwm sim kom txog rau thaum kev tuaj yeem mus rau thaj tsam li ntawm 80%. Tam sim no peb muaj kev ceeb toom thaum ntxov. Ntxiv rau, ntawm chav kawm, peb tsis xav kom tuav cov me nyuam nrog ntau koob. Qhov ntawd zoo heev, thiab.
