Kwiyeza eliseburhulumenteni, uxinzelelo oluphantsi xa kuthengiswa ukuba ixabiso layo lingaphantsi kwe-100/60 mm Hg. Ngaloo nto kuyimfuneko ukuqwalasela ukuba kukho into ebizwa ngokuba yi-physiological hypotension, xa ukunyanzeliswa ngokukhawuleza okusemgangathweni kuqhelekileyo kumntu, kwaye uvakalelwa kakuhle, kwaye ukuphakanyiswa kwimiqathango engummiselo kubangela ukungonakaliswa kwintlalo-ntle.
Impawu eziqhelekileyo zengcinezelo ephantsi
I-hypotension yinyani yimeko yesifo apho ixabiso loxinzelelo liwela phantsi kwexabiso eliqhelekileyo. Ngenxa yokunciphisa i-tone ye-vascular, ukujikeleza kwegazi kuye kwancipha, okukhokelela ekudakaleni kwonikezelo lwe-oksijini kwizitho kunye neenkqubo. Ngenxa yoko, ngexinzelelo lwegazi eliphantsi, kukho impawu zokunciphisa amandla:
- ukukhathala ngokukhawuleza;
- u buqhetseba;
- Ndiziva ndide ndide ndilele;
- ukuphazamiseka nokulahlekelwa kwengqalelo;
- ukuphefumla okufutshane kunye nemithwalo encinane.
Kweminye imiqondiso yexinzelelo oluphantsi, ngokuqhelekileyo ivela:
- ukuphuza ikhanda kwimeko yesimo se-temporal kunye nesipilital, esoloko ibona emva kokulala;
- ukungcola, ngokukodwa ngokuguqulwa okubukhali kwisimo somzimba;
- ukuphazamiseka kunye nokuziva kubanda kwiimilenze (izandla kunye neenyawo ziyakwazi ukuqhayisa nakwiqondo eliphezulu lokusingqongileyo lwangaphandle);
- ukwanda kwenani lentliziyo, ngamanye amaxesha intlungu emva kwe-sternum;
- ukungonakaliswa kwempilo kwiinguqu zemozulu;
- ukungazinzi ngokomzwelo, ukunyusa ukwanda.
Kwixinzelelo eliphantsi kakhulu, ukuphazamiseka kunye nokuwa kweqondo lokushisa komzimba kufakwe kule miqondiso.
Ngokuqhelekileyo, kwixinzelelo eliphantsi, eliqhubekayo ixesha elide, izigulane zinemiqondiso yesifo kwisimo sokuzala: ukuphazamiseka kokuhamba kwindoda kwabesetyhini, kunciphise amandla emadodeni.
Izizathu kunye nokunyangwa koxinzelelo oluphantsi
Izizathu ezibalulekileyo zexpotension ziquka:
- uxinzelelo olude okanye ukukhathazeka kwengqondo;
- ngokugqithiseleyo;
- sebenze kwiimeko ezinobungozi (umswakama ophezulu, ubushushu obushushu, igumbi elingenakunyulwa);
- iingxaki ze-adrenal ne-thyroid gland;
- izifo zesistim ne-cardiovascular system.
Kwiimeko ezintathu zokuqala, ukuba uxinzelelo oluphantsi luchukunyiswa ngokugqithisileyo okanye izinto zangaphandle, akukho zibonakaliso nezinye iimpawu. Ukuba uxinzelelo oluphantsi luchukunyiswa sisifo, ke iimpawu ezithile ezithile zokuphazamiseka komsebenzi wezitho ezithile kunye neenkqubo ziyakongeza kwiimpawu ezisisiseko.
