Uthini umahluko phakathi koluvo lwe-CO2 oluqhelekileyo kunye ne-bypass ye-CO2 sensor?

Siyazi ukuba ngokweendlela ezahlukeneyo zesampulu zokufumanisa igesi, i-CO2 detector ihlukaniswe yaba zizicelo ezimbini: i-CO2 probe eqhelekileyo kunye nemodyuli ye-CO2 ye-sidestream.Nguwuphi umahluko phakathi kwe-mainstream kunye ne-sidestream?

Ngamafutshane, umahluko osisiseko phakathi kwe-mainstream kunye ne-sidestream kukuba ngaba ukuguqula igesi ukusuka kumoya ukuze kuhlalutywe.I-mainstream ayifuni, kwaye i-sensor ye-CO2 eqhelekileyo ihlalutya ngokuthe ngqo igesi kwi-ventilation duct;Umjelo osecaleni uyacinywa.Imodyuli ye-CO2 ye-sidestream idinga ukukhupha igesi ephefumle isigulane kwisampuli kunye nohlalutyo.Irhasi inokuthathwa iisampulu kwiimpumlo okanye kwicatheter yokungenisa umoya.

Eyona nto iphambili kukulinganisa ngokuthe ngqo ukuhamba kwekharbon diokside kumbhobho wokuphefumla kunye ne-CO2 probe eqhelekileyo kwaye uxele ukuphela koxinzelelo lwe-carbon dioxide.I-sidestream kukupompa inxalenye yegesi ngombhobho wesampulu ukuya kwimodyuli yohlalutyo ye-CO2 ukuhlalutya umzobo we-carbon dioxide kwaye unike ingxelo ekupheleni koxinzelelo lwe-carbon dioxide.

Inzwa ye-CO2 ye-Medlinket engundoqo ineenzuzo zokugcina izinto ezisetyenziswayo, ukuqina kunye nokuthembeka okuphezulu.

1. Linganisa ngokuthe ngqo kwindlela yomoya yesigulana

2. Isantya sokuphendula ngokukhawuleza kunye ne-CO2 ecacileyo ye-waveform

3. Ayingcoliswanga ziimfihlo zesigulane

4. Akukho mfuneko yokongeza isahluli samanzi esongezelelweyo kunye nombhobho wesampulu yegesi

5. Isetyenziselwa ikakhulu ukubeka iliso kwizigulane ezine-intubated ezisebenzisa i-respirator ngokuqhubekayo

Izinto eziluncedo zeMedlinket ecaleni komjelo wemodyuli ye-CO2:

1. Irhasi yokuphefumla yomntu owenziwe isampuli ifunxwa ngombhobho wesampulu ngempompo yomoya

2. Imodyuli yohlalutyo lwegesi ikude nesigulane

3. Emva kokudluliselwa, ingasetyenziselwa izigulane ezifakwe kwi-intubated

4. Isetyenziselwa kakhulu ukubeka iliso kwexesha elifutshane lezigulane ezingenayo i-intubated: isebe eliphuthumayo, i-sedation yesigulane ngexesha lokusebenza, igumbi lokubuyisela i-anesthesia.

I-Medlinket ibonelela ngesikimu sokubeka iliso se-ETCO2 esingabizi kakhulu kwikliniki.Imveliso iplagi kunye nokudlala, kwaye yamkele itekhnoloji ye-infrared ye-non spectroscopic ephezulu, enokulinganisa i-concentration ye-CO2 ekhawulezileyo, izinga lokuphefumla, ixabiso le-CO2 lokuphelelwa umoya kunye nokuphefumlelwa kwe-CO2 yoxinaniso lwento evavanyiweyo.Iimveliso ezinxulumene ne-CO2 ziquka i-ETCO2 imodyuli eqhelekileyo, imodyuli ye-ETCO2 yecala kunye ne-ETCO2 imodyuli yecala;Izixhobo zemodyuli ye-CO2 eqhelekileyo ziquka i-adapters yomoya kwizigulane ezingatshatanga zabantu abadala kunye nabantwana, kunye nezixhobo ze-ETCO2 imodyuli ye-sidestream ziquka i-CO2 ye-nasal sampling tube, i-gas path sampling tube, i-adapter, indebe yokuqokelela amanzi, njl.
