Oximetry: zvazviri uye zvakajairika kuzadza kukosha

Zvemukati

• 1. Pulse oximetry (isina-invasive)
• 2. Oximetry / arterial ropa magasi (invasive)
• Zvakajairika kuzadza tsika
• Chengetedza mhedzisiro yakajeka

Oximetry bvunzo inobvumidza iwe kuyera iyo oxygen saturation yeropa, ndiyo chikamu cheoxygen iri kutakurwa muropa. Muedzo uyu, unogona kuitirwa kuchipatara kana kumba uine pulse oximeter, wakakosha kana zvirwere zvinokanganisa kana kukanganisa kushanda kwemapapu, chirwere chemwoyo kana chirwere chetsinga, semuenzaniso.

Kazhinji, oximetry pamusoro pe90% inoratidza yakanaka ropa oxygenation, zvisinei, zvakakosha kuti chiremba aongorore kesi imwe neimwe. Iyo yakaderera ropa oxygenation mwero inogona kuratidza kudiwa kwekurapwa kuchipatara neoksijeni, uye inogona kuratidza mamiriro anotyisidzira hupenyu kana isina kugadziriswa zvakanaka. Nzwisisa kuti ndeipi mhedzisiro yekushaikwa kweo oxygen muropa.

Pane nzira mbiri dzekuyera kuzadza kweokisijeni:

1. Pulse oximetry (isina-invasive)

Iyi ndiyo nzira yakanyanya kushandiswa kuyera kuguta kweoksijeni, sezvo iri nzira isingakuvadzi inoyera huwandu hweoksijeni kuburikidza nechinhu chidiki, chinonzi pulse oximeter, inoiswa inosangana neganda, kazhinji pamucheto pe chigunwe.

Kubatsira kukuru kwechiyero ichi ndechekuti hazvidi kuti utore ropa, uchidzivirira kurumwa. Mukuwedzera kune oximetry, ichi chishandiso chinogona zvakare kuyera imwe data yakakosha, senge huwandu hwekurova kwemoyo uye chiyero chekufema, semuenzaniso.

• Inoshanda sei: iyo pulse oximeter ine mwenje wechiedza unobata huwandu hweoxygen inopfuura muropa pasi penzvimbo irikuitwa bvunzo uye, mumasekondi mashoma, inoratidza kukosha. Aya ma sensors anotora izvozvi, zviyero zvakajairwa uye zvakagadzirirwa kushandiswa paminwe, zvigunwe kana nzeve.

Pulse oximetry inoshandiswa zvakanyanya navanachiremba nevamwe vezvehutano panguva yekuongororwa kwekiriniki, kunyanya mune zviitiko zvezvirwere zvinokonzeresa kufema, senge mapapu, moyo uye chirwere chetsinga, kana panguva yeanesthesia, asi inogona kushandiswa kuongorora mamiriro ehutano kana zvikaitika. yecoronavirus hutachiona. Iyo oximeter inogona zvakare kutengwa kumachiremba kana muzvipatara zvitoro.

2. Oximetry / arterial ropa magasi (invasive)

Kusiyana neopse oximetry, arterial ropa gasi ongororo inzira inopindirana yekuyera mwero weoxygen muropa, sezvazvinoitwa nekuunganidza ropa muchijuru, uye kune izvi tsono tsvimbo inofanirwa. Neichi chikonzero, iyi mhando yekuongorora ishoma kazhinji pane kupomba oximetry.

Kubatsira kwemagasi eropa eropa ndiyo yakaringana muyero wekuzadza oxygen mumuropa, pamusoro pekugona kupa mamwe matanho akakosha, senge huwandu hwekabhoni dhayokisaidhi, pH kana huwandu hweasidhi uye bicarbonate muropa, muenzaniso.

• Inoshanda sei: zvinodikanwa kuita arterial ropa kuunganidzwa uyezve iyi sampuro inotorwa kuti iyerwe mune yakatarwa mudziyo murabhoritari. Iyo tsinga dzeropa dzinonyanya kushandiswa pamhando iyi yekuyera ndeyeiyo radial artery, muchanza, kana chevakadzi, mune kugomera, asi mamwe anogona zvakare kushandiswa.

Iyi mhando yekuyera inowanzo shandiswa chete muzviitiko apo murwere anoda kutariswa achienderera mberi kana zvakanyatso nyatso, zvinova zvakajairika mumamiriro ezvinhu sekuvhiyiwa kukuru, chirwere chemwoyo chakakomba, arrhythmias, hutachiona hwakazara, shanduko kamwe kamwe mukumanikidza kweropa kana mukati zviitiko zvekutadza kufema, semuenzaniso. Dzidza chinonzi kutadza kufema uye kuti ingaderedza sei oxygenation yeropa.

Zvakajairika kuzadza tsika

Munhu ane hutano, ane oxygenation yakakwana yemuviri, anowanzove nekuzadza kweoksijeni pamusoro pe95%, zvisinei, zvakajairika kuti pamamiriro akapfava, senge dzihwa kana dzihwa, kuzadza kuri pakati pe90 ne95%, pasina chikonzero chekunetseka.

Kana iko kuzadza kwasvika pamitengo pazasi pe90%, zvinogona kuratidza kudzikiswa kwekuwanikwa kweoksijeni mumuviri nekuda kwekuvapo kwechimwe chirwere chakakomba icho chinokwanisa kudzikisira kushanda kwekuchinjana kwegasi pakati pemapapu neropa, zvakadai asthma, pneumonia, emphysema, kutadza kwemoyo kana chirwere chetsinga uye kunyangwe kuomarara kweCovid-19, semuenzaniso.

Mune arterial eropa gasi, kuwedzera kune kuyerwa kweoksijeni kuzadza, kukwana okisijeni kumanikidza (Po2) inoongororwawo, iyo inofanirwa kunge iri pakati pe80 ne100 mmHg.

Chengetedza mhedzisiro yakajeka

Izvo zvakakosha kwazvo kuti zvishandiso zvinoyera kuzadza kweoksijeni zvakaenzana nguva dzose, kuti zvidzivise mhedzisiro inoshandurwa. Uye zvakare, kana uchishandisa pulse oximeter, dzimwe nzira dzekudzivirira kushandura bvunzo dzinosanganisira:

• Dzivisa kushandisa enamel kana nzara dzenhema, sezvavanoshandura kupfuura kwechiedza chechiedza;
• Chengetedza ruoko rwakadekara uye pazasi peyero yemoyo;
• Chengetedza chishandiso munzvimbo yakajeka kana ine zuva;
• Ita shuwa kuti chishandiso chakamiswa nemazvo.

Usati watora bvunzo, chiremba anofanirwa kuongororawo zvimwe zvirwere zvakaita sekushomeka kweropa kana kutenderera kweropa, izvo zvinokanganisa kuyerwa kweropa oxygenation.
