Koresha ** Uburyo bubiri bwo gukonjesha mu buryo butaziguye **: (1) Koza buhoro buhoro ibiti byumye hamwe na saline sterile cyangwa amazi yuzuye amacupa utabanje kuyasesagura; (2) kuzinga imibare yaciwe burundu muri ** sterile gauze yoroheje byoroshye na saline sterile **; . na (4) kureremba bifunze igikapu cya pulasitike imbere yikintu cyo hanze cyuzuyemo uruvange rwa ** 50/50 ruvanze nuruvange rwa ice ice hamwe namazi akonje **. ** Ntuzigere ushyira urutoki rwaciwe urubura rwambaye ubusa, paki ya firigo ya gel, cyangwa urubura rwumye **, ikonjesha imiyoboro y'amaraso ya microscopique kandi bigatuma kubaga bidashoboka.

Niba urutoki rwaciwe burundu kumeza yabonetse kandi ikamanikwa kumurongo muto wuruhu, nshobora kubireka nkabihambiraho cyangwa nkabizinga ukundi?¶

** Ntukigere ukata, kugoreka, cyangwa gukuramo ikiraro cyuruhu cyangwa tendon kurutoki rwaciwe igice, nubwo icyo kiraro cyaba cyoroshye gute. Witondere witonze igice cy'urutoki rumanitse kugirango uhuze bisanzwe hamwe n'urutoki rwegeranye rutakomeretse ku gipande cya padi, ubitwikirize hamwe na saline-sterile ya sterile ya gazi, uzenguruke ukuboko wambaye imyenda yumye, kandi ukomeze ukuboko hejuru.

Ni ukubera iki ari bibi gukoresha uruzitiro rucye hamwe na metero ya metero icyarimwe mugihe uciye ibiti bigufi?¶

Iyo usunikishije ikibaho hejuru yicyuma hamwe na ** miter gauge ** mugihe uruzitiro rwa ** rip ** rushyizwe iburyo kuruhande rwiburyo bwiburyo bwikibaho nkigihagararo kirekire, umuhanda uciwe uherutse gucibwa uhinduka ** ufatiwe mumutwe ukomeye hagati yuruzitiro rukomeye rwicyuma rwiburyo hamwe ninyuma izamuka ryinyo yizunguruka yibumoso. Ako kanya gukata birangiye, guhagarika birahinduka, ifata 180 km / h izamuka ryinyo yinyuma, hanyuma irasa inyuma nkamasasu. Igihe cyose ukoresheje uruzitiro rwacagaguye nkuburebure burebure kugirango uhindurwe inshuro nyinshi, burigihe ufate ** umufasha muto wibiti bifasha ibiti imbere yuruzitiro rucye AHEAD kumpera yimbere yicyuma ** bityo inkwi zisukura uruzitiro mbere yo gukoraho amenyo.

Nibihe bikoresho byambere byubufasha bigomba gushyirwa kurukuta rwa buri duka rikora ibiti?¶

Buri duka rikora ibiti rigomba kuba ryubatswe kurukuta ** Hagarika Bleed na Amputation Trauma Kit ** igerwaho mumasegonda 5 yameza yabonye: ** amarushanwa abiri ya CoTCCC yumuyaga wumuyaga **, ** sterile yuzuye 4x4 hamwe nudukariso two munda **, ** gupfunyika igitutu cya salitike zuzuye ** gucamo urutoki **, ** gukomeretsa ihahamuka **, na ** ingabo zikomeye zamaso **. Gufata ubufasha bwambere bwemewe, CPR, no Guhagarika Amaraso kuva kuri Croix-Rouge, Ambulance ya St John, cyangwa umutanga waho aragutegurira gukora byimazeyo mugihe cyihutirwa cyamahugurwa.
