Igazi lakho linomthwalo wokuthwala i-oxygen ezithombeni zakho nakwezinye izicubu. Kodwa-ke, ngezinye izikhathi ebusuku, ayithwali oksijini okuningi njengokuvamile. Le nkinga ibizwa ngokuthi i-désaturation yesikhashana esesikhashana, esho ngamagama alula kusho ukwehla okwesikhashana emazingeni e-oksijeni egazi kusuka emazingeni abo avamile, ama-daytime (" ukugcwala oksijini " yizinga le-oxygen igazi lakho eliphetheyo).
I-désaturation yansuku zonke yesikhashana iyinkinga evamile kubantu abanesifo esingenasifo se-pulmonary chronic obstructive - kungathinta ku-38% kulabo abane- COPD .
Izingozi Zezingozi
Abantu abanempilo abanomsebenzi wamaphaphu evamile ngokuvamile banamazinga okwethula oksijini ephakathi kuka-95% no-100%. Lokhu kusho ukuthi amangqamuzana abo abomvu egazi asebenza eduze noma egcwele okwenziwa oksijini okwenziwe.
Abantu abane-COPD bavame ukuba namazinga aphansi okwehla kwe-oksijeni kunokujwayelekile. Ucwaningo olunye luye lwaphetha ngokuthi amazinga e-oxygen saturation angaphansi kwesikhashana noma angalingana no-93% angakwazi ukubikezela ingozi ephakeme yokudonswa kwe-nocturnal emini ephakathi kwabantu abane-COPD ezinzile.
Ngokuqondile, ukuthi umuntu atholakale ene-désaturation yesikhashana esiphuthumayo, izinga lakhe le-oksijeni lokugcwalisa i-oksijithi kufanele lilahle ngaphezulu kuka-4% kusukela ezingeni elivamile lokusukulwa kwesikhashana okungenani imizuzu emihlanu ngenkathi belele.
Izimbangela
I-désaturation yesikhashana ehamba phambili ingenzeka uma ukuphefumula kwakho kuhamba ngesikhathi sokulala.
Lokhu kwaziwa ngokuthi hypoventilation .
I-Hypoventilation ingabangela ukuguqulwa kwamagesi egazini egazi njenge- hypercapnia (i-carbon dioxide kakhulu) ne- hypoxemia (i-oxygen encane kakhulu) kuziguli ze-COPD, ikakhulukazi ngesikhathi sokulala kwe-REM. Lezi zinguquko zingase ziholele kwiziqephu ezikhulayo zokuvusa nokulala ukuphazamiseka, ukucindezeleka kwe-pulmonary kanye nesilinganiso sokufa esiphakeme.
Ukwengeza, ukuba nezinye izinkinga zokulala ezifana ne- apnea yokulala zingase zandise izinkinga nezimpawu ezihambisana nokukhishwa kwesikhashana sangemva kokuhlwa.
I-désaturation yesikhashana ehamba phambili nayo ingenzeka ngenxa yalokho okubizwa ngokuthi ukungena kwe- ventilation / perfusion , okusho ukuthi isikhathi sokuphefumula kwakho asihambisani nesikhathi segazi lakho elijikelezayo ngamapayipi akho. Lena enye inkinga evamile ezigulini ze-COPD.
Ukucatshangelwa kokuhlola
Kubantu abanesimo esilinganiselwe kuya ku-COPD enzima abasolakala ukuthi bane-désaturation yangemuva yesikhashana, i- oximetry yasekhaya iyithuluzi eliphumelelayo ekuhlolweni kwalesi simo.
Izindlu zangasese zokuhlala ekhaya zilinganisa amazinga e-oxygen saturation ngesikhathi sokulala futhi ifakwe ama-alamu azwakalayo lapho umoya we-oxygen saturation uwe ngaphansi kwezinga elithile. Baphinde baqophe amazinga akho okwenzela umoya we-oxygen ukuze umhlinzeki wakho wezempilo angakuhlola kangcono ukukhishwa kwe-deaturation yangomuso.
Enye ithuluzi eliwusizo ekuboneni ukukhishwa kwe-desaturation yangasese kanye nezinye izinkinga zokulala kungukufunda okulele, okuyaziwa yi-technical term overnight polysomnography (PSG).
Izifundo zokulala zenziwa endaweni elawulwayo, mhlawumbe isikhungo sokulala. Uma ufunda isifundo sokulala, uzobe uhlolwe ngumchwepheshe oqeqeshwe.
Imishini yokucwaninga ngesikhathi esisodwa iqopha imingcele ehlukahlukene yemvelo ehlobene nokulala nokuvuka, kuhlanganise nokuphefumula, izinga lokushaya kwenhliziyo, amazinga e-oksijeni, umsebenzi we-muscle nokunyakaza kwamehlo.
Ukwelapha
Iziguli ezine-désaturation ezinomsoco ezinomsoco omkhulu zizozuza ngokucacile ekutheni ukwelashwa okwenziwe isikhathi eside, ikakhulukazi uma kukhona ubufakazi be-hypoxemia yansuku zonke.
Ukwengeza, uma usebenzisa i-oksijini emini, kufanele ukhulume nomhlinzeki wakho wezempilo mayelana nethuba lokudinga oksijini xaxa lapho ulele ukuze uvimbele ukuchithwa okuqhubekayo ebusuku. Abantu abane-COPD bangase bathole ukuthi balale ubusuku obuhle ngokusebenzisa i-oxygen kuphela ebusuku, kodwa, inzuzo yalokhu ihlala ingacacile.
