ʻO ka hoʻomaka ʻana o ka sensor oxygen olakino, no ke aha e pono ai ʻo RGM i ka sensor oxygen?

Hoʻohana ʻia nā mea ʻike o ka oxygen e ana a nānā i nā pae o ka ʻike o ka oxygen, ka oxygen i inhaled a hoʻopuka ʻia e ka mea maʻi i hoʻopili ʻia i kahi ventilator a i ʻole mīkini anesthesia.
ʻO ka mea ʻike oxygen i loko o kahi mākaʻikaʻi hanu hanu (RGM) e ana i ka neʻe ʻana o ka oxygen (a) ʻāpana ʻāpana oxygen i loko o ka hui kinoea hanu.
Ua ʻike ʻia nā mea ʻike Oxygen ʻo FiO2 sensors a i ʻole O2 batteries, a ʻo ka hapa o ka oxygen inhaled (FiO2) ʻo ia ka neʻe o ka oxygen i loko o ka hui kinoea.ʻO ka hapa o ka oxygen i hoʻoulu ʻia o ka hui kinoea i loko o ka lewa lumi lumi he 21%, ʻo ia hoʻi he 21% ka nui o ka oxygen i loko o ka lumi lumi.
No ke aha e pono ai nā RGM i kahi mea ʻike oxygen?
Hoʻolālā ʻia ka nānā ʻana i ke kinoea hanu e hoʻoneʻe i ka hui ʻana o ka ea a me ka oxygen i loko a i waho o ka māmā o ka mea maʻi e kōkua i ka hanu ʻana, a i ʻole i kekahi mau manawa, e hāʻawi i ka hanu mīkini no ka mea maʻi ʻaʻole lawa ka hanu a ʻaʻole hiki i ke kino ke hanu.
I ka wā o ka hoʻoheheʻe ʻana, pono ke ana pololei ʻana o ka hui kinoea hanu.ʻO ka mea nui, ʻo ke ana ʻana i ka oxygen i ka wā o ka ventila he mea koʻikoʻi ma muli o kona koʻikoʻi i ka metabolism.I kēia hihia, hoʻohana ʻia kahi sensor oxygen e hoʻokele a ʻike i ka hāʻawi ʻana o ka oxygen i helu ʻia e ka mea maʻi.ʻO ke koi nui ka hāʻawi ʻana i ke ana pololei kiʻekiʻe o ka ʻike o ka oxygen i nā kinoea hanu.Mechanisms like 'ole o ka Lapaau Oxygen Sensors
Nā mea ʻike uila
ʻO ka mea ʻike ʻike o ka ʻenekini
1. Electrochemical oxygen sensor
Hoʻohana nui ʻia ka electrochemical oxygen sensing element e ana i ka ʻike o ka oxygen i ka ea ambient.Hoʻopiliʻia kēia mau meaʻike i ka mīkini RGM e ana i ka manaʻo o ka hāʻawi oxygen.Haʻalele lākou i nā hoʻololi kemika i ka mea ʻike, e hopena i ka hoʻopuka uila e like me ka pae oxygen.Hoʻololi nā mea ʻike electrochemical i ka ikehu kemika i ka ikehu uila ma o nā kaʻina hana hoʻoemi a me ka hoʻohaʻahaʻa.Hāʻawi ia i kahi puka uila i ka hāmeʻa e like me ka pakeneka o ka oxygen i ka cathode a me ka anode.Hana ʻia ka mea ʻike oxygen ma ke ʻano he kumu o kēia manawa, no laila e hana ʻia ke ana ʻana o ka volta ma o ka resistor ukana.ʻO ka hopena o kēia manawa o ka meaʻike oxygen e like me ka nui o ka hoʻohana oxygen e ka meaʻike oxygen.
2. ʻO ka meaʻike oxygen fluorescent
Hoʻokumu ʻia nā mea ʻike oxygen Optical ma ke kumu o ka hoʻopau ʻana i ka fluorescence o ka oxygen.Ke hilinaʻi nei lākou i ka hoʻohana ʻana i nā kumu kukui, nā mea ʻike kukui a me nā mea luminescent e pane i ka mālamalama.Ke hoʻololi nei nā mea ʻike oxygen e pili ana i ka luminescence i nā mea ʻike oxygen electrochemical i nā kula he nui.
Ua ʻike lōʻihi ʻia ke kumu o ka molecular oxygen fluorescence quenching.ʻO kekahi mau molekala a i ʻole nā ​​pūhui e hoʻoheheʻe ʻia (ʻo ia hoʻi, hoʻopuka i ka ikehu māmā) ke ʻike ʻia i ka mālamalama.Eia nō naʻe, inā loaʻa nā molekole oxygen, ua hoʻololi ʻia ka ikehu māmā i nā molekele oxygen, e hopena i ka liʻiliʻi o ka fluorescence.Ma ka hoʻohana ʻana i kahi kumu kukui i ʻike ʻia, ʻike ʻia ka ikehu māmā i hoʻohālikelike ʻia i ka helu o nā molekala oxygen i loko o ka hāpana.No laila, ʻike ʻia ka liʻiliʻi o ka fluorescence, ʻoi aku ka nui o nā molekala oxygen i loko o ke kinoea hāpana.
