IPA: /haɪˈpɒksɪə/
KK: /haɪˈpɒksɪə/
A condition where there is not enough oxygen available to the body's tissues.
The climbers experienced hypoxia at high altitudes due to the thin air.
Hypoxia is formed from "hypo-" (meaning under or below) and "oxia" (from Greek "oxus", meaning sharp or acid, which relates to oxygen). The term describes a condition where there is a deficiency of oxygen in the tissues, indicating that the oxygen level is below normal.
Think of 'hypo-' meaning 'under' and 'oxia' relating to 'oxygen' — this helps you remember that hypoxia refers to a state of having less oxygen than normal.
