I-Pulse oximetry

I-Pulse oximetry iyindlela engavamile yokuqapha ukugcwala komoyampilo womuntu (SO2).Nakuba ukufundwa kwayo kwe-peripheral oxygen saturation (SpO2) akufani ngaso sonke isikhathi nokufunda okufiseleka kakhudlwana kwe-arterial oxygen saturation (SaO2) kusukela ekuhlaziyweni kwe-arterial blood gas, lezi zimbili zihlotshaniswa kahle ngendlela ephephile, elula, engavamisile, engabizi kakhulu ye-pulse oximetry. ibalulekile ekulinganiseni ukugcwala komoyampilo ekusetshenzisweni komtholampilo.

Kumodi yayo evamile (edluliselayo) yohlelo lokusebenza, idivayisi yenzwa ibekwa engxenyeni encane yomzimba wesiguli, ngokuvamile iminwe yomunwe noma indlebe, noma esimweni sosana, ngaphesheya konyawo.Idivayisi idlulisa amaza okukhanya amabili engxenyeni yomzimba iye kusithwebuli sezithombe.Ikala ukumunca okushintshashintshayo kubude begagasi ngalinye, ukuyivumela ukuba inqume ukumunca ngenxa yegazi le-arterial eshayayo kuphela, ngaphandle kwegazi le-venous, isikhumba, ithambo, imisipha, amafutha, kanye (ezimweni eziningi) nopholisha wezinzipho.[1]

I-Reflectance pulse oximetry iyindlela ehlukile engajwayelekile kune-transmissive pulse oximetery.Le ndlela ayidingi ingxenye encane yomzimba womuntu ngakho-ke ifaneleka kahle ekusetshenzisweni kwendawo yonke njengezinyawo, ibunzi, nesifuba, kodwa futhi inokulinganiselwa okuthile.I-Vasodilation kanye nokuhlanganisa kwegazi le-venous ekhanda ngenxa yokubuyela kwe-venous ebucayi enhliziyweni kungabangela inhlanganisela ye-arterial kanye ne-venous pulsations esifundeni sasebunzi futhi kuholele emiphumeleni engamanga ye-SpO2.Izimo ezinjalo zenzeka ngenkathi ulaliswa izinzwa nge-endotracheal intubation kanye nokungenisa umoya ngomshini noma ezigulini ezisesimweni se-Tendelenburg.[2]
