This directive prevents mask failure during an emergency, which could lead to hypoxia (lack of oxygen) and incapacitation."}},"importantCases":[],"_links":{"self":"/api/acts/ad-oxy-7-eros-oxygen-masks","history":"/api/acts/ad-oxy-7-eros-oxygen-masks/history","analysis":"/api/acts/ad-oxy-7-eros-oxygen-masks/analysis","conflicts":"/api/acts/ad-oxy-7-eros-oxygen-masks/conflicts","importantCases":"/api/acts/ad-oxy-7-eros-oxygen-masks/important-cases","documents":"/api/acts/ad-oxy-7-eros-oxygen-masks/documents"}}
