Ngoxinzelelo olwandayo lomsebenzi, ukwanda kokudinwa kwengqondo esikolweni, kwaye ukwanda kwengqondo yezifo eziphakathi Ukuvela kwezi meko kukhokelele kubantu abaninzi abangenelela - {2, 2}} {2, 2}}-- {2}. Ukuthenga i-Oxegen yeoksijini yekhaya kunokusombulula ezi meko zenyama kwaye kunesiphumo esibonakalayo ekuphuculeni iimpawu ze-hypoxia. Ke ngoko, akunandaba nokuba leliphi na iqonga okanye imeko abantu abaphakathi, besebenzisa ioksijini yeoksijini yeoksijini yexesha elifanelekileyo kukunciphisa iimpawu ezinamandla.
Okwangoku, ngokuphuculwa kwemigangatho yabantu yokuphila, ingqalelo kwinkathalo yezempilo yosapho inda kakhulu. Ukukhetha unyango lweoksijini efanelekileyo yokuphucula imeko yomzimba kucacile kakhulu. Ukukhetha ukusebenzisa i-chastor yeoksijini yekhaya kunokufezekisa isiphumo esifanelekileyo sexesha elifutshane leoksijini.
