General e ji mara na ojiji nke oxygen

The kasị ukwuu mmewere n'ụwa bụ oxygen: mmiri ya 89% na banyere 21% na ikuku, na ahụ mmadụ - 65%. Ọ na-synthesized artificially na ọtụtụ-eji nkà mmụta ọgwụ na ọgwụgwọ nke dị iche iche nke oxygen agụụ, nakwa dị ka nsi chlorate nnu, nitrites, CO (displaces na carbon monoxide si ya biosoedineny haemoglobin ọbara). Oxygen ọgwụ gosiri na n'ihi na nnukwu hemorrhages, ụkwara nta, na-emighị emi ume, akpa ume edema, n'ihi na ogologo anọ na mkpa ikuku, na na. D.

Gịnị bụ ihe ndị mejupụtara nke oxygen? Ya molekul (O2) mejupụtara abụọ atọm jikọrọ site a covalent nkekọ. Taa, anyị maara na a otutu laabu ụzọ maka njikọ nke a gas. Innovative teknụzụ ekwe na-emepụta ya na ihe ulo oru n'ike. Ihe bụ isi akụrụngwa maka ulo oru oxygen njikọ bụ na mmiri na ikuku. N'ihi na O2 si ikuku ya mbụ gasị na elu nsogbu na quenching, na mgbe distillation e rụrụ na a rectification kọlụm nke ikuku na-ugboro ugboro Takọọ na condensed. Sị na usoro na-enye ohere na-enweta oxygen admixture na inert, haruru (xenon, krypton) na nitrogen (1.5%). Mgbe iji electrolytic mmiri enwetara site na usoro na-enweghị n'elu contaminants O2, haruru.

Maka njirimara nke O2 gas na-anakọtara na tube, ma mee ka egbugbu smoldering. Mgbe oxygen bụ ugbu egbugbu ezumike ma ga-akpọ a na-egbuke egbuke ire ọkụ. Olee ọdịiche dị na oxygen si nitrous oxide? Ya admixture na O2 etolite nitrogen oxides nke na-tọhapụrụ n'ụdị oroma anwụrụ ọkụ.

The usoro nke edinam na ojiji nke oxygen

Na erughi nke a gas ke idem emee anoxia. N'ihi na nke a daa ọrịa nsogbu ọtọ ọrụ nke ụjọ, akụkụ okuku ume na obi usoro pụta ìhè dyspnea, cyanosis, belata ọbara mgbali, na-abịa asphyxia. Mgbe oxygen ndinọ ndị a phenomena akwụsị.

The ojiji nke oxygen na a ngwakọta na CO2. Ụzọ nke ochichi n'ime ahu

Ọtụtụ ụzọ maka ewebata oxygen n'ime ahu: site na inhalation site imi (via na catheter) site n'ọnụ (inhalation site ekwuchite nke Ohiri isi) n'okpuru anụahụ. Subcutaneous ochichi na-eme ka ihe atụ, na ọgwụgwọ nke elephantiasis, ure anụ, venous onya. Ọtụtụ-eji na-akpọ oxygen cocktails - oxygen-ọgaranya na-aba n'anya na ụdị ụfụfụ. Ndị dị otú ahụ iji oxygen na-atụ aro na ọgwụgwọ nke obi na metabolic ọrịa. Ruo ogologo oge otu inhalation nke dị ọcha O2 bụ iwe na mucous membranes nke akụkụ okuku ume tract.

Na-adakarị omume, ezi mgbe, a ngwakọta nke oxygen na CO2 - carbon dioxide, na-enye a na-akpali akpali utịp ke akụkụ okuku ume na center.

Ọgwụ ndị a na-agụnye carbogen (gaghị mgbagwoju anya na karbolenom - ọrụ unyi). Ọ na-echekwara na pụrụ iche cylinders nrụgide. The ojiji nke oxygen na admixture na karbolenom gosiri na ọgwụgwọ nke glaucoma, nakwa dị ka carbon monoxide nsi.
