I-ICC yabo bonke, iminwe yasekunene nasekhohlo yayiyi-0.474, 0.368, kunye ne-0.635 (Itheyibhile 4), ebonisa ukuthembeka komlinganiselo "ombi", "ombi", kunye "nophakathi", ngokulandelanayo.
Ngokutsho kwedatha, i-ICC Model 3 isetyenziswe ngegalelo le-SPSS njengemodeli "yamacala amabini adibeneyo" kunye nohlobo "oluhambelana ngokupheleleyo".
Ngokumalunga nokulungelelaniswa phakathi kwee-PIs ezilinganiswe kwiminwe ye-10, sifumene umahluko omkhulu phakathi kwemilinganiselo.Umnwe ophakathi ubonisa eyona PI iphezulu ilinganiswe phakathi kweminwe yesandla.Nangona ulungelelwaniso phakathi kwe-PI yeminwe ephakathi ekhohlo nasekunene kwakubaluleke ngokwezibalo, i-coefficient of determination (r2) ibonise ukuba malunga ne-8% yeenguqu kwi-PI yomnwe ophakathi osekhohlo unokuqikelelwa ukusuka kumnwe ophakathi wasekunene kwaye ngokuchaseneyo [ 16].
I-PI ibalwa ukusuka kwisignali ye-photoplethysmography ngokuthelekisa i-pulsatile kunye ne-non-pulsatile peripheral circulation.Izinto ezimbini eziphambili zinokuchaphazela i-PI, imveliso yentliziyo, kunye nokulinganisela phakathi kweenkqubo ze-nervous onovelwano kunye ne-parasympathetic.
I-PI iphezulu ukuba imveliso yentliziyo iphezulu kunye / okanye i-parasympathetic iphambili.Ngakolunye uhlangothi, i-PI iphantsi xa imveliso yenhliziyo iphantsi kunye / okanye uvelwano luphambili.Uluhlu oluqhelekileyo lwePI lubhekwa njenge-0.2% ukuya kwi-20% [17].Kuphononongo lwethu, sifumene i-PI ye-4.37 ± 2.07% yomnwe ophakathi osekhohlo kunye ne-4.66 ± 2.18% yomnwe ophakathi.Nangona kunjalo, asizange silinganise imveliso yenhliziyo kunye nenkqubo ye-nervous autonomic ukuba ibeke izimvo kwiimeko ezifanelekileyo zentliziyo kunye nenkqubo ye-nervous.Iziphumo zethu ziqinisekisa idatha ye-Savastan et al.Kubonakala ukuba abantu abaphilileyo abaneminyaka engama-42 ubudala (uluhlu lwe-interquartile = 33-47) bane-PI ye-4.3 (uluhlu lwe-interquartile = 2.9-6.2) [18].
Kwimeko ye-physiological, i-posture ichaphazela i-PI elinganisiweyo, efunyenwe iphantsi kwindawo yokuhlala kwaye iphezulu kwindawo yeTendelenburg [11].Kwisifundo sethu, sisebenzise indawo yokuhlala kubo bonke abathathi-nxaxheba.Ngoko ke, xa sithelekisa kwiminwe, sicinga ukuba i-PI kwinqanaba eliphantsi.Ngenxa yokuba i-PI ngumlinganiselo we-pulsatile ukuya kwi-non-pulsatile blood flow, nasiphi na isifo esonakalisa ukuhamba kwegazi kwi-peripheral sichaphazela i-PI [19].I-PI kwisebe likaxakeka inceda ekuboneni isidingo sotofelo-gazi [20].Kwakhona kunceda ukuvavanya umngcipheko wokufa kwizigulane ezinokopha kwesisu esiphezulu kunye nezigulana ezinomshini wokuphefumula [21,22].Ukongeza, kunceda ukufumanisa i-hypotension ngexesha le-anesthesia kunye nokugqiba ukusebenza kwe-ganglionic blockades [6,7].Kwimeko yokunyamekela kakhulu, i-pulse oximeter iyinxalenye ebalulekileyo yokubeka iliso kwezinye iiparitha kwindawo enye yesibhedlele.Nangona kunjalo, kolu phononongo, sisebenzisa izixhobo ezikumgangatho wabathengi.Ngaloo ndlela, iziphumo zolu phononongo zingenakuthelekiswa nezifundo usebenzisa i-oximeters yesibhedlele.
Ii-oximeters ze-pulse grade grade zingasetyenziswa ngoogqirha bezonyango eziphambili kunye neengcali eziqhelekileyo zokutyelela ekhaya ukulinganisa i-oxygen saturation yesigulane (SpO2) kunye ne-PI.Kufuneka bathathe amanyathelo okunciphisa ukusasazeka kwesi sifo phakathi kwezigulane ezisebenzisa i-probes okanye iincam zeminwe [23].Nangona kunjalo, kufuneka balumke njengoko i-PI ilinganiswa kwiminwe eyahlukeneyo inokunika ufundo olwahlukileyo.Izifundo zangaphambili zibonise ukuba umnwe ophakathi ubonisa amanqanaba aphezulu e-SpO2 xa kuthelekiswa neminye iminwe [24,25].Kolu phononongo, sifumanise ukuba iPI ikwabonise awona manqaku aphezulu kumnwe ophakathi wamalungu omabini.
Olu phononongo lunemida ethile.Siqokelele iisampuli zophando esibhedlele.Iisampulu eziluncedo ziisampuli ezinokwenzeka eziphantsi.Ke ngoko, akunakwenzeka ukuvavanya ukuba umele kangakanani na abemi.Ukongeza, siqokelele kuphela iisampulu kubantu ababonakala besempilweni ukuze kumiselwe i-PI phantsi kweemeko eziqhelekileyo zomzimba.Ke ngoko, iziphumo azinakusebenza kubantu abanayo nayiphi na imeko yezonyango.
I-oximeter ye-pulse ephathekayo kunye nekhaya inokulinganisa i-PI ngokwahlukileyo kwiminwe eyahlukeneyo yesandla sasekhohlo nasekunene.Awona maxabiso aphezulu e-PI afunyenwe kumnwe ophakathi wesandla ngasinye.Ukuthembeka kwePI kulinganiswa ne-pulse oximeter kwiminwe eyahlukeneyo iphantsi.Ngoko ke, i-PI efunyenwe nge-oximeter kufuneka itolikwe ngokuqaphela nayiphi na injongo yokuxilonga.Uphando olongezelelweyo luyafuneka ukuthelekisa ukuthembeka kwesibhedlele kunye ne-oximeters yabathengi ekulinganiseni i-PI yeminwe eyahlukeneyo.
