Zizindikiro zodziwika bwino zimanena za kutentha kwa thupi, kugunda kwa mtima, kupuma komanso kuthamanga kwa magazi. Kupyolera mu kuyang'ana kwa zizindikiro zofunika, tikhoza kumvetsetsa zochitika ndi chitukuko cha matenda, kuti tipereke maziko odalirika a matenda ndi chithandizo chamankhwala. Zida zomwe zimagwiritsidwa ntchito poyang'anira zizindikiro zofunikazi zimatchedwa vital sign monitors.
Odwala kwambiri amafunikira kuyang'anitsitsa nthawi yeniyeni ndi chisamaliro kuchokera kwa ogwira ntchito zachipatala, makamaka odwala matenda a mtima. Kunyalanyaza kulikonse kungakhudze chithandizo cha odwala. Kusintha kwa electrocardiogram kumawonetsa mkhalidwe wamtima ndi mtima. Pofuna kuchepetsa kupanikizika kwa ogwira ntchito zachipatala ndikuthandizira kuyang'anitsitsa nthawi yeniyeni ya wodwalayo, oyang'anitsitsa oyambirira adawonekera mwachibadwa.
M'zaka za m'ma 1970, pamene kugwiritsa ntchito kuwunika kosalekeza kwa bedi kunazindikirika, zizindikiro zofunika kwambiri za odwala zinayamba kuyang'aniridwa nthawi yeniyeni. Mitundu yosiyanasiyana yowunikira zizindikiro ikuwonekera pang'onopang'ono m'zipatala, kuphatikizapo kuthamanga kwa magazi (NIBP), kugunda kwa mtima, kutanthawuza kuthamanga kwa magazi (MAP), kuthamanga kwa magazi (SpO2), kuyang'anira kutentha kwa thupi, etc. . Panthawi imodzimodziyo, chifukwa cha kutchuka ndi kugwiritsa ntchito ma microprocessors ndi machitidwe ofulumira amagetsi, oyang'anira ophatikiza magawo angapo owunikira amazindikiridwa kwambiri ndi ogwira ntchito zachipatala ndipo amagwiritsidwa ntchito kwambiri m'chipatala.
Mfundo yowunikira zizindikiro zofunika ndikulandila chizindikiro chachilengedwe chamunthu kudzera pa sensa, kenako ndikusintha chizindikiro cha biomedical kukhala chizindikiro chamagetsi kudzera pakuzindikira kwa siginecha ndi gawo lokonzekera, ndikuchita zotsogola monga kuponderezana, kusefa kwa ma sign ndi kukulitsa. Kenaka, perekani chitsanzo ndikuwerengera kudzera mu gawo la kutulutsa deta ndi kukonza, ndikuwerengera ndi kusanthula gawo lililonse, yerekezerani zotsatira ndi malo osungiramo, chitani kuyang'anira ndi alamu, ndikusunga zotsatira mu RAM (kutanthauza kukumbukira mwachisawawa) mu nthawi yeniyeni. . Tumizani ku PC, ndipo ma parameter atha kuwonetsedwa munthawi yeniyeni pa PC.
Chowunikira chofunikira chamitundu yambiri chapangidwanso kuyambira pachiwonetsero choyambirira kwambiri mpaka kuwonetsa manambala ndi mawonekedwe pazenera lomwelo. Chiwonetsero cha pulogalamu yowunikira chimasinthidwa ndikusinthidwa nthawi zonse, kuyambira pachiwonetsero choyambirira cha LED, chiwonetsero cha CRT, mpaka chiwonetsero chamadzimadzi cha kristalo, komanso mawonekedwe apamwamba kwambiri amtundu wa TFT pakadali pano, omwe angatsimikizire kusamvana kwakukulu komanso kumveka bwino. , Chotsani vuto loyang'ana, ndipo magawo oyang'anira odwala ndi ma waveform amatha kuwonedwa paliponse. Pogwiritsidwa ntchito, imatha kutsimikizira kutanthauzira kwanthawi yayitali komanso mawonekedwe owoneka bwino kwambiri.
Kuonjezera apo, ndi kuphatikiza kwakukulu kwa mabwalo, kuchuluka kwa owunikira zizindikiro zofunikira kumakhala kochepa komanso kocheperako, ndipo ntchitozo zimakhala zokwanira. Pomwe amayang'anira magawo oyambira monga ECG, NIBP, SPO2, TEMP, ndi zina zambiri, amathanso kuyang'anira mosalekeza kuthamanga kwa magazi, kutulutsa kwamtima, mpweya wapadera wogonetsa ndi zina. Pazifukwa izi, kuwunika kwazizindikiro zofunika kwayamba pang'onopang'ono kukhala ndi ntchito zamphamvu zowunikira mapulogalamu, monga kusanthula kwa arrhythmia, kusanthula kwapang'onopang'ono, kusanthula gawo la ST, ndi zina zambiri, ndikuwunikanso zidziwitso zowunikira malinga ndi zosowa zachipatala, kuphatikiza ma chart amayendedwe ndi zambiri za tebulo Kusungirako. ntchito, nthawi yayitali yosungira, zambiri zambiri.
