Ngaphambi kokusebenzisa:
1. Hlola ikhava yeshubhu kanye nomzimba weshubhu lomqoqi wevacuum.Uma ikhava yeshubhu ivulekile noma umzimba weshubhu wonakele, akuvunyelwe ukusetshenziswa.
2. Hlola ukuthi uhlobo lomkhumbi wokuqoqa igazi luyahambisana yini nohlobo lwesampula okufanele liqoqwe.
3. Thinta yonke imithambo yegazi equkethe izithasiselo eziwuketshezi ukuze uqinisekise ukuthi izithasiselo azihlali kukepisi lekhanda.
Ukusebenzisa:
1. Khetha indawo yokubhoboza bese ufaka inaliti kahle ukuze ugweme ukugeleza kwegazi okungekuhle.
2. Gwema "ukugeleza emuva" ngesikhathi sokubhoboza: ngesikhathi sokuqoqwa kwegazi, hambisa ngobumnene lapho ukhulula ibhande lokucindezela i-pulse.Ungasebenzisi ibhande lokucindezela eliqine kakhulu noma ubophe ibhande lokucindezela ngaphezu komzuzu ongu-1 nganoma yisiphi isikhathi phakathi nenqubo yokubhoboza.Ungalithululi ibhande lokucindezela lapho ukugeleza kwegazi ku-vacuum tube kuyekile.Gcina ingalo neshubhu yevacuum endaweni ebheke phansi (phansi kweshubhu kungaphansi kwesembozo sekhanda).
3. Uma inaliti yokubhoboza ipulaki ishuthekwa emkhunjini wokuqoqa igazi, cindezela ngobumnene isihlalo senaliti senaliti yokubhoboza ipulaki ukuze uvimbele "ukubhampa inaliti".
Ngemva kokusetshenziswa:
1. Ungalikhiphi inaliti ye-venipuncture ngemva kokuba i-vacuum yomkhumbi wokuqoqa igazi isinyamalele ngokuphelele, ukuze uvimbele ichopho lenaliti yokuqoqa igazi ekuvuzeni igazi.
2. Ngemva kokuqoqwa kwegazi, umkhumbi wokuqoqa igazi kufanele uhlehliswe ngokushesha ukuze kuqinisekiswe ukuxubana okuphelele kwegazi nezithasiselo.
