Mushure mekuita chiveve ruoko kana tsoka netsinga, kana chipikiri chapinda nepamunwe kana paruoko, chiremba anokwesha nekubvisa **musoro wembambo wakabudikira **, anoshandisa **sterile surgical bolt cutters kuti acheke musoro wakatsetseka kubva pachipikiri**, uye odhonza mbambo**KUFAMBIRA kunze kuburikidza nekubuda kwembariro nekuseri kwembariro.

Chii chandinofanira kuita kana ruoko kana bhutsu yewandinoshanda naye yakaroverwa zvakananga pamadziro e2x4 kana truss yepadenga?¶

** Usamboedza kubvisa ruoko rwemunhu kana bhutsu kubva pa2x4 stud **, iyo inopinza mbambo mukati memapfupa avo uye kubvarura tsinga netsinga. Panzvimbo pezvo: (1) Bvisa hose yemhepo kana bhatiri kubva papfuti yechipikiri pakarepo; (2) kuita kuti munhu mumwe atsigire ruoko kana gumbo romushandi akuvara saka hapana uremu hunorembera pachipikiri; (3) shandisa **saha rinodzorera, saha yedenderedzwa, kana saha yeruoko kuti ucheke nepakati pe 2x4 stud masendimita gumi nemashanu (6 inches) kumativi ese embambo**; uye (4) takura mushandi kuenda kudhipatimendi rekukurumidzira nebhuroko diki rehuni richiri rakanamirwa pachipikiri.

Sei kukuvara kwembambo nepasi pebhoti yerabha inodikitira iri chimbichimbi chemapfupa kunyangwe ichingobuda ropa?¶

Kana chipikiri chekugadzira chikabaya nepakati perabha uye foam insole yebhutsu yebasa yakasakara mutsoka, iyo muromo wakagomara wembambo inoita kunge cookie-cutter punch, ichityaira core plug ye **rabha, sock fibers, glue resin, uye bhakitiriya inoda dikita inonzi *Pseudomonas aeruginosaal bonerstata deep into the heruginosa***. Kunyange kana gomba rekuboora risisabudise ropa, mabhakitiriya e *Pseudomonas* akavharirwa mukati mebhonzo anokonzera kuparadza **osteomyelitis (bone infection) kana septic arthritis** mukati memazuva kunze kwekunge tsoka yaiswa X-ray, yabviswa pakuvhiyiwa, uye kurapwa neanti-pseudomonal antibiotics uye tetanus booster.

Neiko mumwe munhu akapfurwa pachipfuva nepfuti yechipikiri angagona kufamba ndokutaura sezvaanowanzoita pakutanga, obva adonha maminitsi 15 gare gare?¶

Kana mbambo ye90-millimeter (3.5-inch) inoumbana ikapinda nepakati pechipfuva (**iyo Cardiac Box**), inowanzobaya nepakati pebhonzo repazamu ichipinda mu **right ventricle yemoyo**. Nekuda kwekuti chipikiri chesimbi chakasimba chinoramba chakabatana mumhasuru yemwoyo, chinovhara buri racho kwekanguva. Zvisineyi, kana munhu akaburitsa chipikiri kunze, kana kuti ropa parinovhinza rakatenderedza chipikiri mukati mefibrous **pericardial sac** yakatenderedza moyo, ropa rakavharirwa rinosvina moyo kusvika ratadza kupomba (**cardiac tamponade**). Usambobata mbambo yechipfuva; chengeta akabatwa amire uye fonera 911 / 112 / 999 kuti utakurwe nekukurumidza kuenda kuNhamba 1 Trauma Center. Kutora yakasimbiswa rubatsiro rwekutanga uye CPR kosi kubva kuRed Cross, St John Ambulance, kana mupi wepano anokugadzirira iwe kuitira basa rekukurumidzira.
