He aha ka pilina ma waena o ka pulse a me ke koko oxygen saturation?

I ka hopena o nā makahiki 1990, ua mālama ʻia kekahi mau noiʻi e loiloi i ka pololei o ka poʻe ʻoihana ʻole, nā mea pane mua, nā paramedics a me nā kauka i ka loiloi wale ʻana i ka hele ʻana o ka pulse.Ma hoʻokahi haʻawina, ʻoi aku ka haʻahaʻa o ka holomua o ka ʻike ʻana i ka pulse e like me 45%, ʻoiai ma kahi noiʻi ʻē aʻe, ua hoʻohana nā kauka ʻōpio i ka awelika o 18 kekona e ʻike i ka pulse.

No kēia mau kumu e like me nā ʻōlelo aʻoaʻo a ke Kōmike Resuscitation International, ua kāpae ke Kōmike Resuscitation Pelekane a me ka American Heart Association i ka nānā pinepine ʻana i ka pulse ma ke ʻano he hōʻailona o ke ola mai ka hoʻomaʻamaʻa kōkua mua i hoʻonui ʻia ma 2000.

Akā, he waiwai maoli ka nānā ʻana i ka pulse, E like me nā hōʻailona koʻikoʻi a pau, ʻo ka ʻike inā ʻaʻole i loko o ka pae maʻamau ka mea i ʻeha e hiki ke hōʻike i ka ʻike nui iā mākou;

Inā ʻaʻole i loko o kēia mau pae ka pulse o ka poʻe ʻeha, hiki iā ia ke alakaʻi iā mākou i nā pilikia kikoʻī.Inā holo kekahi, manaʻo mākou e piʻi aʻe ko lākou pulse.Makemake mākou iā lākou e wela, ʻulaʻula a hanu wikiwiki.Ināʻaʻole lākou i holo a puni, akā he wela, heʻulaʻula, he pōkole ka hanu a me ka puʻupuʻu wikiwiki, hiki iā mākou ke loaʻa ka pilikia, hiki ke hōʻike i ka sepsis.Inā he poʻe make lākou;wela, ʻulaʻula, lohi a ikaika ka puʻupuʻu, hōʻike paha kēia i kahi ʻeha poʻo i loko.Inā ʻeha lākou, anu, ʻeleʻele a me ka puʻuwai wikiwiki, loaʻa paha iā lākou ka haʻalulu hypovolemic.

E hoʻohana mākou i ka pulse oximeter:Pulse oximeterhe mea hana diagnostic liʻiliʻi i hoʻohana nui ʻia e ʻike i ka saturation oxygen koko o ka poʻe ʻeha, akā hiki ke hōʻike pū i ka pulse o ka mea ʻeha.Me kekahi o lākou, ʻaʻole pono mākou e hoʻonele i ka manawa e hōʻea ai i ka poʻe i hōʻeha ʻia a manaʻo i ka ʻeha nui.

ʻO ke ʻano o ka pulse oximetry e ana i ka nui o ka oxygen i lawe ʻia i loko o ke koko ma ke ʻano he pākēneka.E hoʻohana i ka pulse oximeter e ana ma kou manamana lima.Ua kapa ʻia kēia ana ʻo Sp02 (peripheral oxygen saturation), a he kuhi ia o Sp02 (arterial oxygen saturation).

ʻO ka hemoglobin i loko o ke koko ʻulaʻula e lawe i ka oxygen (kahi mea liʻiliʻi i hoʻoheheʻe ʻia i ke koko).Hiki i kēlā me kēia mole hemoglobin ke lawe i 4 mau moleke oxygen.Inā hoʻopaʻa ʻia kāu hemoglobin a pau i ʻehā mau molekele oxygen, a laila e "saturated" kou koko me ka oxygen, a ʻo kāu SpO2 he 100%.

ʻAʻole loaʻa ka hapa nui o ka poʻe i ka 100% oxygen saturation, no laila ua manaʻo ʻia ka laulā o 95-99% maʻamau.

Hiki ke hōʻike i kēlā me kēia index ma lalo o 95% i ka hypoxia-hypoxic oxygen e komo i loko o nā kiko.

ʻO ka emi ʻana o SpO2 ka hōʻailona hilinaʻi loa o ka hypoxia o kahi mea make;ʻO ka piʻi ʻana o ka hanu hanu pili i ka hypoxia, akā aia nā hōʻike ʻaʻole i lawa ka ikaika o kēia pilina (a aia nō i nā hihia āpau) i hōʻailona o ka hypoxia.

ʻO kaoximeter pulupuluhe mea hana diagnostic wikiwiki e hiki ai iā ʻoe ke ana a nānā i ka pae oxygenation o ka mea i make.ʻO ka ʻike ʻana e hiki nō i ka Sp02 ʻeha ke hiki iā ʻoe ke hāʻawi i ka nui o ka oxygen i loko o ka pae akamai.

ʻOiai ʻo ka saturation oxygen koko i loko o ka laulā maʻamau, ua hoʻemi ʻia ʻo SpO2 e 3% a ʻoi aku paha, he hōʻailona ia no ka loiloi piha ʻana o ka mea maʻi (a me ka hōʻailona oximeter), no ka mea ʻo ia paha ka hōʻike mua o ka maʻi maʻi.
