Ngenkathi i-classicibhande lesifuba lokushaya kwenhliziyokusalokhu kuyindlela ethandwayo, iziqaphi zesilinganiso senhliziyo ezibonakalayo seziqalile ukuthola amandla, zombili ngaphansi kwe-ama-smartwatchfuthiizilandeleli zokufanelekaesihlakaleni, nanjengamadivayisi azimele engalweni. Ake sibhale izinzuzo nezingozi zeziqaphi zesilinganiso senhliziyo esihlakaleni.
Ochwepheshe
Kanye nokwanda kwezindlela zokulandelela ukuqina kwemisipha ezisekelwe esihlakaleni njenge-Apple Watch, i-Fitbits, kanye ne-Wahoo ELEMNT Rival, sibona nokusetshenziswa kabanzi kwezindlela zokuqapha izinga lokushaya kwenhliziyo ezisebenzisa i-optical. Izinga lokushaya kwenhliziyo elisebenzisa i-optical liye lasetshenziswa ezindaweni zezokwelapha iminyaka eminingi:iziqeshana zeminwe zisetshenziselwa ukukala izinga lokushaya kwenhliziyousebenzisa i-photoplethysmography (PPG). Ngokukhanyisa ukukhanya okunamandla aphansi esikhumbeni sakho, izinzwa zingafunda ukuguquguquka kokugeleza kwegazi ngaphansi kwesikhumba futhi zithole izinga lokushaya kwenhliziyo, kanye nezilinganiso eziyinkimbinkimbi kakhulu ezifana nomoya-mpilo wegazi, eziye zahlolwa ngesikhathi sokudlondlobala kwe-COVID-19.
Njengoba kungenzeka ukuthi ugqoke iwashi noma i-tracker yokufaneleka komzimba noma kunjalo, kunengqondo ukuthinta inzwa yokushaya kwenhliziyo engezansi kwesikhwama ngoba izothinta isikhumba sakho. Lokhu kuvumela idivayisi ukuthi ifunde izinga lokushaya kwenhliziyo yakho (noma, kwezinye izimo, idlulisele ekhanda lakho) ngenkathi ushayela, futhi inikeza nezibalo ezengeziwe zezempilo nokufaneleka njengokushaya kwenhliziyo okuphumuzayo, ukuguquguquka kwesilinganiso sokushaya kwenhliziyo, kanye nokuhlaziywa kokulala. — kuye ngedivayisi.
Kunezinhlobo eziningi ze-armband yokushaya kwenhliziyo esebenza ngezindlela eziningi e-CHILEAF, njengei-CL830 Step Countingr Armband Heart Rate Monitor,Isikrini Sokushaya Kwenhliziyo Sokubhukuda XZ831futhiIsiqaphi Sezinga Lenhliziyo Langempela Se-Oxygen Segazi se-CL837ezinikeza ukusebenza okufanayo nebhande lesifuba kodwa kusukela esihlakaleni, engalweni noma kuma-biceps.
Ububi
Izinzwa zesilinganiso senhliziyo ezibonakalayo nazo zinezinkinga eziningi, ikakhulukazi uma kukhulunywa ngokunemba. Kuneziqondiso zesitayela sokugqoka (ukulingana okuqinile, ngaphezu kwesandla) futhi ukunemba kuncike esikhumbeni, izinwele, ama-moles kanye nama-freckles. Ngenxa yalezi ziguquguquko, abantu ababili abagqoke imodeli yewashi elifanayo noma inzwa yesilinganiso senhliziyo bangase babe nokunemba okuhlukile. Ngokufanayo, akukho ukushoda kwezivivinyo embonini yokugibela amabhayisikili/ukufaneleka kanye namajenali abuyekezwe ontanga abonisa ukuthi ukunemba kwazo kungahluka kusuka ku-+/- 1% kuya ku-+/- izinga lamaphutha. Isayensi Yezemidlalo ngo-2019 Ucwaningo lubonise amaphesenti angu-13.5.
Umthombo walokhu kuphambuka uhlobene kakhulu nendlela kanye nendawo lapho izinga lokushaya kwenhliziyo lifundwa khona. Izinga lokushaya kwenhliziyo elibonakalayo lidinga ukuthi inzwa ihlale inamathele esikhumbeni ukuze igcine ukunemba kwayo. Uma uqala ukuzishukumisa - njengalapho ugibela ibhayisikili - noma ngabe iwashi noma inzwa iqinisiwe, zisanyakaza kancane, okwenza umsebenzi wazo ube nzima kakhulu. Lokhu kusekelwa ucwaningo lwango-2018 olwanyatheliswa kuyi-Cardiovascular Diagnosis and Therapy, olwahlola uhlobo lwenzwa yokushaya kwenhliziyo ekhanyayo kubagijimi abagijima ku-treadmill isikhathi sokuhlolwa. Njengoba ukuqina kokuzilolonga kwakho kukhuphuka, ukunemba kwenzwa yokushaya kwenhliziyo ekhanyayo kuyancipha.
Kusetshenziswa izinzwa ezahlukene kanye nama-algorithm. Ezinye zisebenzisa ama-LED amathathu, ezinye zisebenzisa amabili, ezinye zisebenzisa oluhlaza kuphela kanti ezinye zisasebenzisa ama-LED anemibala emithathu okusho ukuthi ezinye zizoba nembe kakhulu kunezinye. Kunzima ukusho ukuthi kuyini.
Ngokuvamile, ezivivinyweni esizenzile, izinzwa zesilinganiso senhliziyo ezibonakala kahle zisahluleka ngokunemba, kodwa zibonakala zinikeza inkomba enhle yesilinganiso senhliziyo yakho ngenkathi usebenza - into efana nomjaho weZwift. - Ngokuvamile, isilinganiso senhliziyo yakho esimaphakathi, isilinganiso senhliziyo ephezulu, kanye nesilinganiso senhliziyo esiphansi kuzohambisana nebhande lesifuba.
Kungakhathaliseki ukuthi uziqeqesha ngokusekelwe esilinganisweni senhliziyo yakho kuphela, noma ulandelela noma yiluphi uhlobo lwenkinga yenhliziyo (qala ngokubuza udokotela wakho mayelana nalokhu okulandelayo), ibhande lesifuba liyindlela yokufinyelela ukunemba kwephuzu nephuzu. Uma ungaqeqeshi nje ngokusekelwe esilinganisweni senhliziyo yakho, kodwa ufuna nje izitayela, i-optical heart rate monitor izokwanela.
