Hypoxic conditions are detrimental to living organisms. In a conservation context, hypoxia may be deliberately induced as a means of preservation of materials or pest control. For the extreme condition in which oxygen is below 0.1% or absent, use "anoxia." For a medical condition characterized by low blood oxygen, use "anoxemia," for which "hypoxemia" is a used for term.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:related rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31304742"/><skos:related rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31361586"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31298688"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14053725"> <skos:prefLabel xml:lang="es">hypoxia (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9823826"> <skos:prefLabel xml:lang="ca">hypoxia (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:21:58</dct:created>  </skos:Concept></rdf:RDF>
