Izimpawu ezibalulekile zibhekisela esikhathini esijwayelekile sokushisa komzimba, ukushaya kwenhliziyo, ukuphefumula kanye nomfutho wegazi. Ngokubheka izimpawu ezibalulekile, singakwazi ukuqonda ukuvela nokuthuthukiswa kwezifo, ukuze sinikeze isisekelo esithembekile sokuxilongwa nokwelashwa emtholampilo. Amathuluzi asetshenziswa ukuqapha lezi zimpawu ezibalulekile abizwa ngokuthi ama-vaal sign monitors.
Iziguli ezigula kakhulu zidinga ukubhekwa ngesikhathi sangempela nokunakekelwa kwabasebenzi bezokwelapha, ikakhulukazi iziguli ezinezifo zenhliziyo nemithambo yegazi. Noma yikuphi ukunganaki kungase kuphazamise ukwelashwa kweziguli. Izinguquko ku-electrocardiogram zibonisa isimo senhliziyo nenhliziyo. Ukuze kuncishiswe ingcindezi kubasebenzi bezokwelapha futhi kube lula ukubhekwa kwesikhathi sangempela kwesimo sesiguli, abaqaphi bokuqala bavele ngokwemvelo.
Ngeminyaka yawo-1970, njengoba inani lokusetshenziswa kokuqapha eceleni kombhede laqashelwa, izimpawu ezibaluleke kakhulu zeziguli zaqala ukugadwa ngesikhathi sangempela. Izinhlobonhlobo zokuqapha ipharamitha yezimpawu zibonakala kancane kancane ezibhedlela, okuhlanganisa umfutho wegazi ongahlaseli (i-NIBP), izinga lokushaya kwenhliziyo, umfutho wegazi ophakathi (MAP), ukugcwala komoyampilo wegazi (SpO2), ukuqapha izinga lokushisa lomzimba, njll. ekuqapheni kwesikhathi sangempela . Ngesikhathi esifanayo, ngenxa yokuthandwa nokusetshenziswa kwama-microprocessors kanye nezinhlelo ze-elekthronikhi ezisheshayo, abaqaphi abahlanganisa imingcele eminingi yokuqapha baya ngokuya baqashelwa ngabasebenzi bezokwelapha futhi basetshenziswa kabanzi emisebenzini yomtholampilo.
Umgomo wokuqapha izimpawu ezibalulekile uwukwamukela isignali yebhayoloji yomuntu ngenzwa, bese uguqula isignali ye-biomedical ibe isignali kagesi ngokusebenzisa ukutholwa kwesignali kanye nemojula yokucubungula ngaphambili, futhi wenze ukucubungula kwangaphambili okufana nokucindezelwa kokuphazamiseka, ukuhlunga isignali nokukhulisa. Bese, isampula futhi ulinganise ngokusebenzisa imojula yokukhishwa kwedatha kanye nokucubungula, futhi ubale futhi uhlaziye ipharamitha ngayinye, uqhathanise umphumela nomkhawulo obekiwe, wenze ukugada kanye ne-alamu, futhi ugcine idatha yomphumela ku-RAM (ebhekisela kumemori yokufinyelela okungahleliwe) ngesikhathi sangempela. . Ithumele ku-PC, futhi amanani epharamitha angaboniswa ngesikhathi sangempela ku-PC.
Imonitha yophawu olubalulekile enamapharamitha amaningi nayo ithuthukile kusukela ekubonisweni kwe-waveform yakudala kuya ekubonisweni kwezinombolo namagagasi esikrinini esifanayo. Isibonisi sesikrini semonitha sibuyekezwa njalo futhi sithuthukiswe, kusukela kusibonisi sokuqala se-LED, isibonisi se-CRT, kuya ekubonisweni kwekristalu ewuketshezi, kanye nesibonisi esithuthuke kakhulu sombala we-TFT okwamanje, esingaqinisekisa ukucaca okuphezulu nokucaca. , Qeda inkinga ye-engeli yokubuka, futhi imingcele yokuqapha isiguli kanye nama-waveforms angabonwa ngokuphelele kunoma iyiphi i-engeli. Uma isetshenziswa, ingaqinisekisa isikhathi eside ukucaca okuphezulu kanye nemiphumela yokubukwayo enokukhanya okuphezulu.
Ukwengeza, ngokuhlanganiswa okuphezulu kwamasekethe, umthamo wabaqaphi bezimpawu ezibalulekile uvame ukuba mncane futhi ube mncane, futhi imisebenzi iphelele kakhulu. Ngenkathi beqapha amapharamitha ayisisekelo njenge-ECG, NIBP, SPO2, TEMP, njll., bangaphinda baqaphe ngokuqhubekayo umfutho wegazi ohlaselayo, ukuphuma kwenhliziyo, igesi ekhethekile yokubulala izinzwa neminye imingcele. Ngalesi sisekelo, i-monitor yezimpawu ezibalulekile ithuthuke kancane kancane ukuze ibe nemisebenzi enamandla yokuhlaziya isofthiwe, njengokuhlaziywa kwe-arrhythmia, ukuhlaziywa kwe-pacing, ukuhlaziywa kwengxenye ye-ST, njll., futhi ingabuyekeza ulwazi lokuqapha ngokuvumelana nezidingo zomtholampilo, okuhlanganisa amashadi ezitayela nolwazi lwetafula Isitoreji. umsebenzi, isikhathi eside sokulondoloza, inani elikhulu lolwazi.
