Choking kana asphyxia inonetsa mukufema, iyo inokonzerwa nekushaya oxygen. Nemhaka yeizvi, muviri unowedzera huwandu hwekhabhoni dioxide. Chirwere chacho chinotungamirira kumagumo ekugoverwa kwe okisijeni kuuropi. Nokudaro, kana munhu akaora mwoyo, rubatsiro rwekutanga runodikanwa. Kazhinji kazhinji, kufanana nehana inowanikwa sechikonzero chemuviri wekune imwe nyika unopinda mumugwagwa wekupemha.
Kusiyana kwehurumende:
- kwete-ane chisimba ( mwoyo wemafi , chimiro chedema semugumisiro wemagetsi uye vamwe);
- chisimba (kuvhara chipfupa chepamusoro, kufema chifupa kana mutsipa).
Rubatsiro rwekutanga kana munhu akaora mwoyo
Kubva pane zvinokonzera uye chiitiko chazvino chemunhu akabatwa, zvakakosha kuita zviito zvakasiyana. Saka, kana munhu akaziva, unofanira kuita zvinotevera:
- Tsanangura kwaari izvo zvichazoitwa kuti kuderedze mamiriro acho ezvinhu.
- Kumutsa murume kumakumbo ake, kumira pamusana, kupinza ruoko rwake murukanda ndokuisa chigunwe chake mudumbu.
- Ruoko rwechipiri runoraramira pamusoro paro, uye rwunosungirirwa neboka rinopinza.
- Izvi zvinofanira kudzokororwa kazhinji kusvikira ndege dzisina mahwanda.
Kana munhu asina chaanoziva, zviito zvinotevera zvinoitwa:
- Munhu akakodzera anofanira kuiswa pamusana wake.
- Kanda musoro wako kuti usimudze chin
- Kana dumbu nebhokisi zvisingafambi - pakarepo unotanga kuita kupfurikidza.
- Kana munhu asingakwanise kuisa mweya, munhu akakuvara anofanira kuiswa mu coma pose, kuisa maoko maviri pamusoro pejaya uye kushandisa zvinetso (dzokorora kana zvichidikanwa kazhinji).
Chirwere chekutanga chekutanga panguva yekurwisa kwemafi inofanira kutanga nezviratidzo zvakadai se:
- kukundikana kutaura;
- kufema kusinganzwisisiki kwakaperekedzwa nemirairo yeakakanganiswa kumutsipa kana mapapu;
- ganda rebhuruu, misumari nemiromo;
- kurasikirwa kwekuziva .
