Igazi lakho lithwala i-oxygen emzimbeni wakho wonke, futhi lilawula inani le-oksijini elihle kakhulu. Uma ungenawo oksijini okwanele egazini lakho, leso simo siyaziwa njenge-hypoxemia.
I-hypoxemia ibonakala ingajwayelekile kubantu abane-advanced chronic obstructive pulmonary disease ( COPD ). Kungabangela nezinye izimo zamaphaphu, njengemdlavuza wamaphaphu, i-pneumonia, i-asthma, ne-bronchitis.
Izinga le-oksijeni legazi lilinganiswa ngamamitha ayi-mercury (mm Hg), futhi izinga elivamile le-oxygen emithanjeni yakho liphakathi kuka-75 kuya ku-100 mm Hg. Abantu abane-COPD banamazinga aphansi. Uma unezinga eliphansi kakhulu, ungase udinge oksijini okungeziwe. Kodwa-ke, ukunikeza oksijeni ngokweqile kungaba yingozi, futhi, ngakho udokotela wakho uzodinga ukusebenza nawe ukuthola ibhalansi elungile.
Kungenzeka futhi ukusebenzisa i- pulse oximetry ukukala izinga lakho le-oksijeni yegazi ekhaya. Khuluma nodokotela wakho mayelana nokuthi yikuphi ukufundwa okufanele ukulindele kusuka ekupheni kwe-pulse futhi lapho ufuna usizo lwezokwelapha ukuze ufunde okuphansi.
Izimpawu
Izimpawu ze-hypoxemia zifaka ukudideka, ukuphefumula nokukhuphuka komfutho wegazi lakho kanye nesilinganiso senhliziyo yakho njengoba umzimba wakho uzama ukukhokhela oksijini ephansi egazini lakho. Abantu abane-COPD abahlukunyezwa yi-hypoxemia uma bephumule cishe banenkinga yokugxila noma ukukhumbula izinto, futhi lezo zinkinga ziba zimbi nakakhulu njengoba i-hypoxemia yabo iqhubeka.
E-hypoxemia enamandla, ungase uqale ukuthuthumela noma ugibele, isikhumba sakho singabanda futhi siphume, futhi ungase uqale ukuphenduka okwesibhakabhaka. Lesi sibonakaliso sokugcina, esibizwa ngokuthi i-cyanosis, sibonisa ukuthi akukho igazi elanele elinomoya okwenza amangqamuzana akho. Lezi zimpawu zibonisa isimo esiphuthumayo, futhi kufanele ufune usizo ngokushesha.
I-hypoxyemia ivame ukuholela ku-hypoxia , okusho ukuthi awunawo oksijini okwanele okufika ezithombeni zakho. Eqinisweni, abantu abaningi badidisa igama elithi "hypoxemia" negama elithi "hypoxia," kodwa lezi ezimbili azifani - i-hypoxemia ibhekisela ku-oxygen ephansi egazini lakho, kuyilapho i-hypoxia ibhekisela ku-oksijini ephansi ezicukheni zakho.
Kungenzeka ukuthi ube ne-hypoxemia ngaphandle kwe-hypoxia uma umzimba wakho uhlawulela amazinga akho egazi aphansi oksijini ngokuthuthukisa inani le-oksijini elifinyelela ngempela izicubu zakho (ngokwesibonelo, ngokwenza inhliziyo yakho ishaye ngokushesha ukuhambisa igazi eliphethe i-oksijini ngokushesha). Kungenzeka futhi ukuthi ube ne-hypoxia ngaphandle kwe-hypoxemia, uma ukulethwa okwamanje kwe-oksijini kumaseli akho kungasebenzi kahle, noma uma amaseli akho engakwazi ukusebenzisa i-oksijini ngendlela efanele.
Okufanele Ukwenze Uma Usola I-Hypoxemia
I-hypoxemia enamandla iyiphuthumayo yezokwelapha. Uma unesifo se-hypoxemia esinamandla, ikakhulukazi uma unesifo se-COPD noma esinye isifo esibangela ukuba ube ne-hypoxemia, funa ukunakekelwa okuphuthumayo ngokushesha.
Uma ukuhlola kwakho kwezokwelapha kubonisa ukuthi une-hypoxemia engapheli, udokotela wakho angase akucomele ukuthi uhambe nge- oksijeni eyengeziwe . Kodwa-ke, i-oksijeni eyongezelayo ayisizo wonke umuntu, ngakho-ke uzodinga ukuxoxa ngenzuzo kanye nocansi nodokotela wakho.
Abanye abantu abaneCOPD bahlushwa yi-hypoxemia ebusuku. Lokhu kwenzeka ngenxa yokuguqula ukuphefumula ngesikhathi sokulala okunciphisa inani le-oxygen elifinyelela igazi lakho. Kubantu abangenawo i-COPD, lezi zinguquko zokuphefumula aziba nomthelela onjalo, kepha kubantu abano-COPD bangabangela i-hypoxemia. Iziguli ze-COPD ezinenkinga yobunene be-hypoxemia phakathi nosuku zingase zithande kakhulu i-hypoxemia ebusuku. Khuluma nodokotela wakho uma unezimpawu ebusuku.
