Kodi pali ubale wotani pakati pa pulse ndi oxygen saturation ya magazi?

Chakumapeto kwa zaka za m'ma 1990, maphunziro angapo adachitidwa kuti awone kulondola kwa anthu omwe si akatswiri, oyankha koyamba, othandizira opaleshoni komanso madokotala poyesa kukhalapo kwa pulse.Mu kafukufuku wina, chiwopsezo cha kuzindikira kugunda chinali chochepera 45%, pomwe mu kafukufuku wina, madotolo achichepere amatha pafupifupi masekondi 18 kuti azindikire kugunda kwa mtima.

FM-054

Ndi pazifukwa izi kuti malinga ndi malingaliro a International Resuscitation Committee, Komiti Yotsitsimula Yaku Britain ndi American Heart Association idaletsa kuwunika pafupipafupi ngati chizindikiro cha moyo kuchokera ku maphunziro othandizira oyamba omwe adasinthidwa mu 2000.

Koma kuyang'ana kugunda kwa mtima n'kofunika kwambiri, Mofanana ndi zizindikiro zonse zofunika kwambiri, kudziwa ngati kugunda kwa mtima kwa munthu wovulalayo kuli moyenerera kungatiuze zambiri;

Ngati kugunda kwa ovulala sikuli mkati mwa magawo awa, kungatifikitse ku zovuta zinazake.Ngati wina athamanga mozungulira, timayembekezera kuti kugunda kwake kukukwera.Timafunanso kuti azitentha, ofiira komanso azipuma mofulumira.Ngati sanathamangire mozungulira, koma ndi otentha, ofiira, kupuma pang'ono komanso kuthamanga mofulumira, tikhoza kukhala ndi vuto, lomwe lingasonyeze sepsis.Ngati ali ovulala;kutentha, kufiira, pang'onopang'ono komanso kugunda kwamphamvu, izi zikhoza kusonyeza kuvulala kwa mutu wamkati.Ngati avulazidwa, ozizira, otumbululuka komanso akugunda mofulumira, akhoza kukhala ndi hypovolemic shock.

Timagwiritsa ntchito pulse oximeter:Pulse oximeterndi chida chaching'ono chodziwira chomwe chimagwiritsidwa ntchito pozindikira kuchuluka kwa okosijeni m'magazi a ovulala, komanso kuwonetsa kugunda kwa ovulala.Ndi imodzi mwa izo, sitiyenera kutaya nthawi kuti tifike kwa ovulala ndikumva kugunda koopsa.

Njira ya pulse oximetry imayesa kuchuluka kwa mpweya wotengedwa m'magazi monga peresenti.Gwiritsani ntchito pulse oximeter kuyeza chala chanu.Muyezo umenewu umatchedwa Sp02 (peripheral oxygen saturation), ndipo ndi chiyerekezo cha Sp02 (arterial oxygen saturation).

Maselo ofiira a m'magazi a hemoglobini amanyamula mpweya (yochepa imasungunuka m'magazi).Molekyu iliyonse ya himogulobini imatha kunyamula mamolekyu 4 a okosijeni.Ngati hemoglobini yanu yonse imamangiriridwa ku mamolekyu anayi a okosijeni, ndiye kuti magazi anu "adzadzaza" ndi mpweya, ndipo SpO2 yanu idzakhala 100%.

Anthu ambiri alibe 100% machulukitsidwe okosijeni, kotero osiyanasiyana 95-99% amaonedwa zachilendo.

Mlozera uliwonse womwe uli pansi pa 95% ukhoza kusonyeza kuti mpweya wa hypoxia-hypoxic udzalowa mu minofu.

Kutsika kwa SpO2 ndiye chizindikiro chodalirika cha hypoxia ya wovulalayo;kuwonjezeka kwa kupuma kumakhudzana ndi hypoxia, koma pali umboni wakuti kugwirizana kumeneku sikokwanira (ndipo ngakhale kulipo nthawi zonse) kukhala chizindikiro cha hypoxia.

Thepulse oximeterndi chida chodziwira mwachangu chomwe chimakulolani kuyeza ndikuwunika kuchuluka kwa okosijeni kwa wovulalayo.Kudziwa kuti Sp02 yovulalayo imathanso kukuthandizani kuti mupereke mpweya wokwanira mkati mwa luso.

Ngakhale kuti mpweya wa okosijeni m'magazi uli m'kati mwachibadwa, SpO2 imachepetsedwa ndi 3% kapena kuposerapo, chomwe ndi chizindikiro cha kuwunika mozama kwa wodwalayo (ndi chizindikiro cha oximeter), chifukwa ichi chikhoza kukhala umboni woyamba wa matenda aakulu.
