Uyini umoya ocebisisiwe futhi kungani abatshuzi beyocwila ngomoya ocebisisiwe?
Umoya ocebile, owaziwa nangokuthi i-nitrox, ungolunye uhlobo lomoya onomoya-mpilo ongaphezu kuka-21%. U-21% umoya-mpilo uwumoya ovamile esiwuphefumulayo emhlabeni. Inzuzo eyinhloko yokusebenzisa umoya ocebile ukunweba isikhathi sokucwilisa phansi, nokunciphisa isidingo sokucindezela kuze kube yilapho kungekho mkhawulo wokucindezela. Lokhu kuzuzisa kakhulu ekujuleni. Ngokwesibonelo, ekujuleni okungamamitha angu-80, umoya ovamile ungahlala cishe imizuzu engu-30, kuyilapho umoya ocebile one-32% oksijini ungahlala imizuzu engu-45 no-36% ungahlala imizuzu engu-55. Nakuba umoya owenziwe waba muhle ngempela ekwandiseni isikhathi esichithwa phansi, kubalulekile ukuba abatshuzi baqeqeshelwe ukuwusebenzisa ngaphambi kokutshuza ngomoya owenziwe waba muhle.
