Ndechipi chisanganiswa chomhepo kana kuti gasi chinoshandiswa zvikurusa mukudonha kwevaraidzo.
Context:Nokuda kwokudonha, musanganiswa wegasi wakasiyana nemhepo yemuchadenga yakajairika (21% okisijeni, 78% nitrogen, 1% magasi anoratidza) anogona kushandiswa, chero bedzi munhu anodhonzera ane unyanzvi mukushandisa kwavo. Musanganiswa unonyanya kushandiswa unonzi nitrox, unonziwo Enriched Air Nitrox (EAN), unova mweya une okisijeni yakawedzerwa, kazhinji ine 32% kana 36% okisijeni, uye nokudaro ine nitrogen shoma, ichideredza njodzi yekurwara kwe decompression kana kubvumira kuratidzwa kwenguva refu kune imwechete yekumanikidza kune njodzi yakaenzana. Nitrogen yakaderedzwa inogonawo kubvumira kusamira kana kuti kupfupisa nguva dzokumira dzokudzvinyirira kana kuti kupfupisa nzvimbo pakati pekudonha. Pfungwa yenhema yakajairika ndeyokuti nitrox inogona kuderedza narcosis, asi kunzvera kwakaratidza kuti okisijeni inonyaradzawo.: 304
Nokuda kwokudonha kunofadza zvikurusa mhepo yomumhepo ine 21% oksijeni uye 78% nitrogen inoshandiswa. Musanganiswa wechipiri unowanzoshandiswa unonzi Enriched Air Nitrox une okisijeni yakawedzerwa ne32% kana kuti 36% uye ine Nitrogen shoma pane inowanikwa mumhepo yomudenga, iyo inobvumira vanozama mvura kuti vambomira kwenguva pfupi kana kuti vambomira kwenguva pfupi.
