Iigesi zegazi

Iigesi zegazi zilinganisa ukuba ingakanani ioksijini kunye nekhabhon diokside esegazini lakho. Ziye zamisela neasidi yegazi lakho.

Ngokwesiqhelo, igazi lithathwa kwimithambo. Ngamanye amaxesha, igazi elivela emthanjeni linokusetyenziswa (igesi yegazi).

Eyona nto iqhelekileyo, igazi linokuqokelelwa kwenye yezi umthambo zilandelayo:

• Umthambo ojikelezayo esihlahleni
• Umthambo wobufazi kwi-groin
• Umthambo weBrachial engalweni

Umboneleli wezempilo unokuvavanya ukusasazeka kwesandla phambi kokuba athathe isampuli yegazi kwindawo yesihlahla.

Umboneleli ufaka inaliti encinci ngesikhumba kumthambo. Isampulu ithunyelwa ngokukhawuleza elabhoratri ukuze ihlolwe.

Akukho lungiselelo lukhethekileyo. Ukuba ukwonyango lweoksijini, uxinzelelo lweoksijini kufuneka luhlale luhleli kangangemizuzu engama-20 ngaphambi kovavanyo.

Xelela umboneleli wakho ukuba uthatha nawaphi na amayeza okucoca igazi (ii-anticoagulants), kubandakanya iasprini.

Xa kufakwa inaliti ukutsala igazi, abanye abantu baziva iintlungu eziphakathi. Abanye baziva behlaba okanye behlaba kuphela. Emva koko, kunokubakho ukubetha okanye ukutyumza kancinci. Oku kuya kuhamba kungekudala. Ubuhlungu kunye nokuphazamiseka zihlala zibi ngaphezu kokutsala igazi kwi-vein.

Uvavanyo lusetyenziselwa ukuvavanya izifo zokuphefumla kunye neemeko ezichaphazela imiphunga. Inceda ekumiseleni ukusebenza konyango lweoksijini okanye umoya ongenayo (i-BiPAP). Uvavanyo lukwabonelela ngolwazi malunga ne-asidi yomzimba / ibhalansi yomzimba, enokuthi ibonakalise imikhondo ebalulekileyo malunga nokusebenza kwemiphunga kunye nezintso kunye nesimo somzimba ngokubanzi.

Amaxabiso kwinqanaba lolwandle:

• Uxinzelelo lwe-oksijini (PaO2): i-75 ukuya kwi-100 yeemilimitha ze-mercury (mm Hg), okanye i-10.5 ukuya kwi-13.5 kilopascal (kPa)
• Uxinzelelo oluyinxalenye lwekharbhon diokside (PaCO2): 38 ukuya kuma-42 mm Hg (5.1 ukuya ku-5.6 kPa)
• Igazi le-arterial pH: 7.38 ukuya kwi-7.42
• Ukugcwaliswa kweoksijini (SaO2): 94% ukuya kwi-100%
• I-Bicarbonate (HCO3): i-22 ukuya kwi-28 yeemililitha ngokulinganayo ilitha nganye (mEq / L)

Ukuphakama kweenyawo ezingama-3,000 (900 yeemitha) nangaphezulu, ixabiso leoksijini liphantsi.

Amaxabiso esiqhelo ahluka kancinci phakathi kweelebhu ezahlukeneyo. Ezinye iilebhu zibandakanya imilinganiselo eyahlukeneyo. Thetha nogqirha wakho malunga nentsingiselo yeziphumo zakho zovavanyo.

Iziphumo ezingaqhelekanga zinokubangelwa yimiphunga, izintso, isifo se-metabolic, okanye amayeza. Ukulimala kweNtloko okanye kwentamo okanye okunye ukulimala okuchaphazela ukuphefumla kunokukhokelela kwiziphumo ezingaqhelekanga.

Kukho umngcipheko omncinci xa inkqubo yenziwe ngokuchanekileyo. Imithambo kunye nemithambo iyahluka ngobukhulu ukusuka komnye umntu ukuya komnye nakwelinye icala lomzimba liye kwelinye. Ukuthatha igazi kwabanye abantu kunokuba nzima ngakumbi kunabanye.

Eminye imingcipheko enxulumene nokutsalwa kwegazi incinci, kodwa inokubandakanya:

• Ukufa isiqaqa okanye ukuziva ungenantloko
• Ukugqobhoza okuninzi ukufumana imithambo yegazi
• I-Hematoma (igazi elakhiweyo phantsi kolusu)
• Ukopha kakhulu
• Usulelo (umngcipheko omncinci nangaliphi na ixesha ulusu lwaphukile)
