Ubwino wa Pulse Oximeter

Pulse oximetry ndiyosavuta kwambiri pakuyesa kosalekeza kosalekeza kwa kuchuluka kwa oxygen m'magazi.Mosiyana ndi zimenezi, mulingo wa mpweya wa m'magazi uyenera kutsimikiziridwa mu labotale pamiyeso ya magazi otengedwa.Pulse oximetry ndi yothandiza pa malo aliwonse omwe mpweya wa oxygen wa wodwala umakhala wosakhazikika, kuphatikizapo chisamaliro chambiri, opaleshoni, kuchira, zochitika zadzidzidzi ndi chipatala, oyendetsa ndege omwe sali opanikizika, kuti awone momwe wodwalayo alili, komanso kudziwa momwe angagwiritsire ntchito kapena kufunikira kwa mpweya wowonjezera. .Ngakhale kuti pulse oximeter imagwiritsidwa ntchito poyang'anira mpweya wa okosijeni, sungathe kudziwa kagayidwe ka oxygen, kapena kuchuluka kwa mpweya womwe umagwiritsidwa ntchito ndi wodwala.Pachifukwa ichi, ndikofunikira kuyezanso milingo ya carbon dioxide (CO2).N'zotheka kuti angagwiritsidwenso ntchito kuzindikira zolakwika mu mpweya wabwino.Komabe, kugwiritsa ntchito pulse oximeter kuti azindikire hypoventilation kumasokonekera ndi kugwiritsa ntchito mpweya wowonjezera, chifukwa ndi pamene odwala amapuma mpweya wa chipinda kuti zovuta za kupuma zimatha kudziwika modalirika ndi ntchito yake.Choncho, kachitidwe ka chizolowezi cha okosijeni wowonjezera kungakhale kosayenera ngati wodwalayo amatha kukhala ndi mpweya wokwanira mu mpweya wa chipinda, chifukwa zingayambitse hypoventilation kupita mosadziwika.

Chifukwa chosavuta kugwiritsa ntchito komanso kuthekera kopereka machulukidwe a okosijeni mosalekeza komanso nthawi yomweyo, ma pulse oximeters ndi ofunikira kwambiri pamankhwala azadzidzidzi komanso ndi othandiza kwambiri kwa odwala omwe ali ndi vuto la kupuma kapena mtima, makamaka COPD, kapena kuzindikira matenda ena ogona. monga kupuma movutikira ndi hypopnea.Kwa odwala omwe ali ndi vuto loletsa kugona, kuwerengera kwa pulse oximetry kudzakhala mu 70% 90% kwa nthawi yambiri yoyesera kugona.

Ma pulse oximeter oyenda ndi batire ndi othandiza kwa oyendetsa ndege omwe sali opanikizika pamwamba pa 10,000 mapazi (3,000 m) kapena 12,500 mapazi (3,800 m) ku US komwe mpweya wowonjezera umafunikira.Ma pulse oximeters amathanso kukhala othandiza kwa okwera mapiri ndi othamanga omwe mpweya wawo wa okosijeni umachepa akamakwera kwambiri kapena akamachita masewera olimbitsa thupi.Ma pulse oximeters ena amagwiritsa ntchito chipangizo chojambulira mpweya wa okosijeni wa magazi ndi kugunda kwa mtima kwa wodwala, zomwe zimamukumbutsa kuti aone kuchuluka kwa okosijeni m'magazi.

Kupita patsogolo kwa maulumikizidwe kwapangitsa kuti odwala azitha kuyang'anira kuchuluka kwa okosijeni m'magazi awo mosalekeza popanda kulumikizidwa ndi chingwe ndi chowunikira chachipatala, osataya kutulutsa kwa data ya odwala kubwerera kwa oyang'anira pafupi ndi bedi ndi machitidwe apakati oyang'anira odwala.

Kwa odwala omwe ali ndi COVID-19, pulse oximetry imathandiza kuzindikira msanga hypoxia yopanda phokoso, momwe odwala amawonekerabe komanso omasuka, koma SpO2 yawo ndiyotsika kwambiri.Izi zimachitika kwa odwala omwe ali m'chipatala kapena kunyumba.Low SpO2 ikhoza kuwonetsa chibayo chokhudzana ndi COVID-19, chomwe chimafuna mpweya wabwino.
