Pulse oximetersua hoʻohana ʻia e loiloi i ke kūlana o ka oxygen o nā maʻi ma nā ʻano hoʻonohonoho maʻi like ʻole ua lilo a ʻoi aku ka nui o nā mea nānā maʻamau.Hāʻawi ia i ka nānā mau ʻana, ʻaʻole invasive o ka hemoglobin oxygen saturation i ke koko arterial.E hōʻano hou kēlā me kēia hawewe pulse i kona hopena.
ʻAʻole hāʻawi nā Pulse oximeters i ka ʻike e pili ana i ka neʻe ʻana o ka hemoglobin, ka puka ʻana o ka naʻau, ka maikaʻi o ka hāʻawi ʻana i ka oxygen i nā ʻiʻo, ka hoʻohana ʻana i ka oxygen, oxygenation, a i ʻole ka lawa o ka ea.Eia nō naʻe, hāʻawi lākou i kahi manawa e ʻike koke ai i nā ʻokoʻa mai ka pae o ka oxygen o ka mea maʻi, ma ke ʻano he hōʻailona hōʻailona mua i nā kauka e kōkua i ka pale ʻana i nā hopena o ka desaturation a e ʻike i ka hypoxemia ma mua o ka hiki ʻana o ka osis.
Ua manaʻo ʻia e hoʻonui i ka hoʻohana ʻananā oximeter puʻupuʻuma nā keʻena maʻamau e hiki ke hana maʻamau e like me nā thermometers.Eia naʻe, ua hōʻike ʻia he liʻiliʻi ka ʻike o nā limahana i ka hana ʻana o nā mea hana, a me ka ʻike liʻiliʻi o ke kumu hana o nā mea hana a me nā kumu e pili ana i ka heluhelu.
Ke hoʻohālikelike ʻia me ka hemoglobin i hoʻemi ʻia, hiki i nā oximeters pulse ke ana i ka absorption o nā nalu kikoʻī o ka māmā i loko o ka hemoglobin oxidized.He ʻulaʻula ke koko oxygenated arterial ma muli o ka nui o ka hemoglobin i loaʻa i loko, e hiki ai iā ia ke komo i kekahi mau nalu o ka mālamalama.He ʻelua kukui-emitting diodes (LED) ma kekahi ʻaoʻao o ka probe, hoʻokahi ʻulaʻula a hoʻokahi infrared.Hoʻokomo ʻia ka probe ma kahi ʻāpana kūpono o ke kino, maʻamau ka manamana lima a i ʻole ka pepeiao pepeiao, a hoʻouna ka LED i ka nalu o ka mālamalama i ka photodetector ma kēlā ʻaoʻao o ka probe ma o ke koko arterial pulsating.Hoʻopili ka Oxyhemoglobin i ke kukui infrared;ʻO ka emi ʻana o ka hemoglobin ka hopena i ke kukui ʻulaʻula.ʻO ke koko arterial pulsatile i loko o ka systole e hoʻoheheʻe ʻia ka hemoglobin oxygen i loko o ka ʻiʻo, e komo i nā kukui infrared hou aʻe, a e ʻae i ka liʻiliʻi o ka mālamalama e hiki i ka photodetector.Hoʻoholo ka saturation oxygen o ke koko i ke kiʻekiʻe o ka lawe māmā.Hoʻopili ʻia ka hopena i kahi hōʻike kikohoʻe o ka saturation oxygen ma ka pale oximeter, i hōʻike ʻia e SpO2.
Nui nā mea hana a me nā hiʻohiʻona o nā pulse oximeters.Hāʻawi ka hapa nui i ka hōʻike nalu kikohoʻe kikohoʻe, ke kani ʻana o ka arterial audible a me ka hōʻike ʻana o ka puʻuwai puʻuwai, a me nā mea ʻike like ʻole e kūpono i ka poʻe o ka makahiki, ka nui a i ʻole ke kaumaha.Aia ke koho i nā hoʻonohonoho e hoʻohana ai.Pono nā limahana a pau e hoʻohana ana i ka pulse oximeters e hoʻomaopopo i kāna hana a me ka hoʻohana pono ʻana.
ʻOi aku ka pololei o ka nānā ʻana i ke kinoea koko aʻa;akā naʻe, manaʻo ʻia ʻo ka pulse oximetry e lawa pono no ka nui o nā kumu lapaʻau ma muli o nā palena i ʻike ʻia.
ʻO ke kūlana maʻi-No ka helu ʻana i ka ʻokoʻa ma waena o nā capillaries a me nā capillaries ʻole, e ana ka oximetry i ka lawe māmā ʻana o nā puʻupuʻu lehulehu (maʻa mau ʻelima).I mea e ʻike ai i ke kahe ʻana o ke koko, pono e hoʻokō pono i ka perfusion ma ka wahi i nānā ʻia.Inā nāwaliwali a i ʻole ʻole ka puʻuwai peripheral o ka mea maʻi, ʻo kaoximeter pulupuluʻaʻole pololei ka heluhelu ʻana.ʻO ka poʻe maʻi i pilikia loa i ka hypoperfusion, ʻo ia ka poʻe me ka hypotension, hypovolemia, hypothermia, a me ka poʻe i hopu ʻia i ka naʻau.ʻO ka poʻe i loaʻa i ke anu akā ʻaʻole ka hypothermia hiki ke loaʻa ka vasoconstriction ma ko lākou manamana lima a me nā manamana wāwae a hiki ke hōʻino i ke kahe koko.
Inā hoʻopaʻa paʻa loa ka probe, hiki ke ʻike ʻia nā pulsations non-arterial, e hoʻoulu ai i nā pulsations venous ma ka manamana lima.Hoʻokumu ʻia ka puʻuwai venous ma ka ʻaoʻao ʻākau o ka puʻuwai, tricuspid regurgitation, a me ka tourniquet o ke kahe koko ma luna o ka ʻimi.
Hiki i ka arrhythmia o ka puʻuwai ke hoʻoulu i nā hopena ana pololei ʻole, ʻoi aku ka nui inā loaʻa kahi apex/iwi deficit nui.
ʻO nā mea hoʻonanea i hoʻohana ʻia i nā diagnostics a me nā hoʻāʻo hemodynamic hiki ke kumu i nā kuhi hewa ʻole o ka saturation oxygen, maʻamau haʻahaʻa.Pono e noʻonoʻo ʻia nā hopena o ka pigmentation ʻili, jaundice, a i ʻole kiʻekiʻe bilirubin kiʻekiʻe.
ʻO ka hoʻohana pololei ʻana i ke ana ʻana o ka pulse oximetry ʻaʻole wale ka heluhelu ʻana i ka hōʻike kikohoʻe, akā ʻoi aku ka nui, no ka mea ʻaʻole i loaʻa i nā maʻi āpau me ka SpO2 like ka ʻike oxygen i loko o ke koko.ʻO ka saturation o 97% ʻo ia ka 97% o ka nui o ka hemoglobin i loko o ke kino e hoʻopiha ʻia me nā molekole oxygen.No laila, pono e wehewehe ʻia ka saturation oxygen ma ke ʻano o ka pae hemoglobin holoʻokoʻa o ka mea maʻi.ʻO kekahi kumu e pili ana i ka heluhelu ʻana o ka oximeter, ʻo ia ka paʻa o ka hemoglobin i ka oxygen, hiki ke ʻano like me nā loli i nā kūlana physiological.
