Kev Pabcuam Ua Ntej
Inhalation: Txav tus neeg raug tsim txom mus rau huab cua ntshiab, ua pa qhib thiab so.Yog tias tsis zoo, nrhiav kev kho mob / kev sab laj.
Kev sib cuag ntawm daim tawv nqaij: Tshem tawm / tshem tawm tag nrho cov khaub ncaws uas tsis huv tam sim ntawd.Ntxuav daim tawv nqaij nrog dej / da dej.
Yog daim tawv nqaij khaus lossis pob khaus tshwm sim: Nrhiav kev kho mob / kev sab laj.
KEV TIV THAIV: Ua tib zoo ntxuav nrog dej rau ob peb feeb.Yog tias yooj yim thiab ua tau yooj yim, tshem cov looj tsom iav.Txuas ntxiv ntxuav.
Yog qhov muag khaus: Nrhiav kev kho mob/kev sab laj.
TSEEM CEEB: Yog tias muaj qhov tsis xis nyob, nrhiav kev kho mob / kev sab laj.Yaug qhov ncauj.
Kev tiv thaiv thaum muaj xwm txheej ceev: Cov neeg cawm siav yuav tsum hnav cov khoom tiv thaiv tus kheej, xws li hnab looj tes roj hmab thiab looj tsom iav.
Kev ntsuas hluav taws kub
Cov tshuaj tua hluav taws tsim nyog: hmoov qhuav, ua npuas dej, pos huab, carbon dioxide
Kev phom sij tshwj xeeb: Ceev faj, kub kub lossis kub siab tuaj yeem ua kom tawg los ua cov pa luam yeeb.
Txoj kev tshwj xeeb: tua hluav taws los ntawm sab saud, xaiv txoj kev tua hluav taws tsim nyog raws li ib puag ncig ib puag ncig.
Cov neeg ua haujlwm tsis muaj feem cuam tshuam yuav tsum khiav mus rau qhov chaw nyab xeeb.
Thaum qhov chaw nyob ib puag ncig raug hluav taws kub: Yog tias muaj kev nyab xeeb, tshem cov thawv tshem tawm.
Cov cuab yeej tiv thaiv tshwj xeeb rau cov neeg tua hluav taws: Ib txwm hnav cov khoom tiv thaiv tus kheej thaum tua hluav taws.
Cov lus teb xwm txheej kub ntxhov rau qhov nchuav
Kev tiv thaiv tus kheej, cov khoom siv tiv thaiv, siv cov khoom tiv thaiv tus kheej.Cia kom deb ntawm qhov nchuav / tawm thiab cua hlob.
Kev ntsuas kub ceev: cheeb tsam txeej yuav tsum tau kaw nrog txoj siv sia, thiab lwm yam, kom tswj tau cov neeg ua haujlwm tsis muaj feem cuam tshuam.
Kev ntsuas ib puag ncig: Tiv thaiv kev nkag mus rau hauv cov kav dej.
Cov txheej txheem thiab cov khoom siv rau kev tswj thiab tu: cheb thiab sau cov plua plav thiab kaw rau hauv cov thawv ntim cua.Saib xyuas kom tsis txhob tawg.Cov ntaub ntawv txuas lossis cov khoom khaws cia yuav tsum muab pov tseg tam sim ntawd raws li Txoj Cai thiab cov cai tsim nyog rau kev pov tseg.
