Indlela yokusebenza yenzwa ifana neyenaliti ehlala ngaphakathi kwe-venous.Ngemva kokubhoboza ukubona ukubuya kwegazi, umthambo wesiguli uyacindezelwa, umgogodla yenaliti ukhishwa, inzwa yokucindezela ixhunywa ngokushesha, futhi ukopha endaweni yokubhoboza kuyalungiswa.Umsebenzisi ucindezela i-radial artery yesiguli kanye nomthambo we-ulnar ngezandla zombili, ubheka ukuthi ukugcwala komoyampilo wegazi weminwe yesiguli kumugqa oqondile, futhi ubheka i-waveform kumonitha ye-ECG.Uma kuvela i-waveform ye-oxygen saturation ye-electrocardiogram, kusho ukuthi ukujikeleza ohlangothini lokukhululwa kuhle.Ake sibheke izinyathelo zokuphepha zokusebenzisa inzwa yomfutho wegazi?
1. Naka ukwelashwa kwe-exhaust kusengaphambili
Sebenzisa indlela efanayo ukuhlola umthambo ngakolunye uhlangothi, futhi ungabona i-waveform nenani lapho ukhulula noma yiluphi uhlangothi.Ngaphambi kokuhlinzwa, beka isiguli endaweni efanele, ubeke isitho esingenhla ohlangothini olubhoboziwe endaweni efanele, khipha futhi ukhiphe ngomjovo we-saline evamile kanye nomjovo we-heparin sodium, inzwa yokucindezela inzwa nokukhipha umoya kuqinile kakhulu, futhi awudingi umoya. amabhamuza, qala ngokushintsha ukushintshwa kwezindlela ezintathu kwe-sensor Exhaust uye ohlangothini lwesiguli, bese ulungisela komunye umkhawulo.Ngemva kokukhathala, hlola futhi ukuthi akhona yini amabhamuza omoya epayipini.Uma kukhona amabhamuza omoya kunzwa yokucindezela, kuzodala i-arterial embolism futhi kubangele imiphumela emibi kakhulu.Cindezela uketshezi kunzwa bese ubheka ukuthi akhona yini amabhamuza omoya kunzwa ngenkathi ucindezela.
2. Qaphela ukuthi inzwa yokucindezela ixhunywe kusibonisi
Ngemuva kokuthi uxhumano luphumelele, yenza izinguquko kumonitha we-ECG, futhi ulungise igama lenzwa yokucindezela entweni yokusebenza ehambisanayo.Indawo yenzwa ye-arterial yakha umugqa oqondile ovundlile nesikhala sesine se-intercostal somugqa wesiguli we-midaxillary, ixhuma i-tee endaweni yokulungisa inzwa emkhathini, bese ikhetha ukulungiswa kwe-zero kumonitha.Lapho ukuqapha kwe-ECG kukhombisa ukuthi ukulungiswa kwe-zero kuphumelele, xhuma i-tee ekugcineni komkhathi, futhi i-waveform yokuqapha umfutho wegazi wesiguli kanye nenani livela ngalesi sikhathi, futhi inzwa yokucindezela kanye nepayipi kulungiswa ngokuphakanyiswa.Uma ukunemba kwevelu yokuqapha umfutho wegazi kungatshazwa, lapho uguqula noma ushintsha indawo yomzimba ngesikhathi sokushintsha, kuyadingeka ukwenza ukulinganisa uziro futhi.
Sekukonke, izinyathelo zokuphepha zokusetshenziswa kwenzwa yomfutho wegazi zihlanganisa ukunaka ukwelashwa kokukhipha kusengaphambili, nokunaka ukuxhumeka kwenzwa yokucindezela kumqapha.Ekulinganisweni kwe-zero, isiguli sisendaweni engenhla futhi i-transducer yokucindezela isezingeni elifanayo nendawo yesiguli ye-midaxillary yesine ye-intercostal.Bhala phansi usuku nesikhathi sefilimu, hlela izimpahla, ubeke isiguli ngokunethezeka, hlela umbhede wesiguli, njll., bese ubheka izimpawu ezibalulekile zesiguli.
