Ọkwa oxygen dị n'ọbara (ihe dị n'ọbara oxygen nke akwara ozi) na-egosi ọkwa oxygen dị n'ọbara na-erute na akwara nke ahụ.Nnwale ABG na-eji ọbara a na-enweta site na akwara, nke enwere ike tụọ tupu ọ banye n'anụ ahụ mmadụ.A ga-etinye ọbara ahụ n'ime igwe ABG (onye nyocha ọbara ọbara), nke na-enye ọkwa oxygen ọbara n'ụdị nrụgide akụkụ oxygen (oxygen partial pressure).
A na-achọpụtakarị hyperoxaemia site na iji ule ABG, nke akọwara dị ka ọkwa oxygen ọbara karịa 120 mmHg.Nrụgide ikuku oxygen nkịtị (PaO2) nke a na-atụ n'iji nyocha ọbara akwara (ABG) dị ihe dịka 75 ruo 100 mmHg (75-100 mmHg).Mgbe ọkwa dị n'okpuru 75 mmHg, a na-akpọkarị ọnọdụ a dị ka hypoxemia.A na-ewere ọkwa dị n'okpuru 60 mmHg dị obere ma na-egosi mkpa ọ dị maka mgbakwunye oxygen.A na-enye ikuku oxygen mgbakwunye site na cylinder oxygen, nke ejikọrọ na imi site na tube nwere ma ọ bụ na-enweghị ihe mkpuchi.
Kedu ihe kwesịrị ịbụ ikuku oxygen?
A nwekwara ike tụọ ọkwa oxygen n'ọbara site na iji ngwa a na-akpọ pulse oximeter.Ọkwa oxygen nkịtị na oximeter pulse na-abụkarị 95% ruo 100%.Ihe na-erughị 90% nke ọkwa oxygen dị ala (hypoxemia).A na-achọpụtakarị hyperoxaemia site na ule ABG, nke akọwara dị ka ọkwa oxygen dị n'ọbara karịa 120 mmHg.Nke a na-abụkarị n'ụlọ ọgwụ, mgbe onye ọrịa na-enweta nrụgide dị elu nke oxygen mgbakwunye ogologo oge (3 ruo 10 awa ma ọ bụ karịa).
Kedu ihe na-eme ka ọkwa oxygen dị n'ọbara belata?
Ọkwa oxygen nwere ike ibelata n'ihi nsogbu ọ bụla:
Ọdịnaya oxygen dị n'ikuku dị ala: N'ebe dị elu dị ka ugwu ugwu, ikuku oxygen dị na mbara igwe dị oke ala.
A na-ebelata ike ahụ mmadụ iji nweta ikuku oxygen: Nke a nwere ike ịkpata ọrịa ngụgụ ndị na-esonụ: Asthma, emphysema (mmebi nke akpa ikuku na ngụgụ), bronchitis, oyi baa, pneumothorax (mmiri ikuku n'etiti ngụgụ na mgbidi obi), nnukwu.
