Mutsara 1: Heliair ichagara iine okisijeni inodarika 21 % uye ichava hypoxic nokuda kwezvinosanganiswa zvine helium isingasviki 20 % (oxygen isingasviki 17%) Mutsara wechipiri: Heliair ichagara iine okisijeni inodarika 21%, uye ichava hypoxic (pasi pe17% okisijeni) nokuda kwemisanganiswa ine pasi pe20% yehelium. Mubvunzo: Mutsara wokutanga nomutsara wechipiri unoreva chinhu chimwe chete here? Hungu kana kuti Aiwa?
