ʻOhi ʻĀpana Koko Heparin Tube
ʻO ka wehewehe pōkole:
ʻO ka Heparin Blood Collection Tubes he ʻōmaʻomaʻo a loaʻa i ka lithium maloʻo, sodium a i ʻole ammonium heparin ma nā paia o loko a hoʻohana ʻia i ka kemika clinical, immunology a me serology. koko / plasma hāpana.
Hemorheology, spelled haemorheology (mai ka Helene 'αἷμα,haima'koko' a me ka rheology, mai ka Helene ῥέωrhéō, 'kahe' a me -λoγία,-logia'study of'), a i ʻole koko rheology, ʻo ia ke aʻo ʻana i nā waiwai kahe o ke koko a me kona mau mea o ka plasma a me nā pūnaewele. Hiki ke loaʻa ka perfusion kiko kūpono inā aia wale nā waiwai rheological o ke koko i loko o kekahi mau pae. Hoʻoholo ʻia ka viscosity koko e ka plasma viscosity, hematocrit (kahi hapa nui o ke koko ʻulaʻula, ʻo ia ka 99.9% o nā mea cellular) a me nā waiwai mechanical o nā ʻulaʻula ʻulaʻula. hua'ōlelo erythrocyte deformability a me erythrocyte aggregation. No ia mea, hana ke koko ma ke ano he wai non-Newtonian. No laila, ʻokoʻa ka viscosity o ke koko me ka nui o ka shear. a i ʻole ma ka peak-systole.No laila, he wai hoʻoheheʻe ʻia ke koko. Eia naʻe, piʻi ka viscosity koko i ka wā e iho ai ka shear rate me ka hoʻonui ʻana i nā anawaena moku a i ʻole me ke kahe haʻahaʻa, e like me ke kahawai mai kahi keakea a i ka diastole. Piʻi pū ka viscosity koko me piʻi i ka ʻulaʻula aggregability.
Koko viscosity
ʻO ka viscosity koko kahi ana o ke kūʻē o ke koko e kahe.Hiki ke wehewehe ʻia ʻo ia ka mānoanoa a me ka paʻa o ke koko.ʻO kēia waiwai biophysical ka mea hoʻoholo koʻikoʻi o ka hakakā ʻana i nā paia o ka moku, ka wikiwiki o ka hoʻihoʻi venous, ka hana e pono ai no ka puʻuwai e puhi i ke koko, a me ka nui o ka oxygen e lawe ʻia i nā ʻiʻo a me nā kino.ʻO kēia mau hana o ka ʻōnaehana cardiovascular e pili pono ana i ke kūpaʻa vascular, preload, afterload, a me ka perfusion, kēlā me kēia.
ʻO nā mea hoʻoholo mua o ka viscosity koko he hematocrit, ʻulaʻula ʻulaʻula deformability, ʻulaʻula ʻulaʻula aggregation, a me ka viscosity plasma. nā protein i loko o ka plasma. Akā naʻe, ʻoi aku ka ikaika o ka hematocrit i ka viscosity koko holoʻokoʻa.Hiki i ka hoʻonui ʻana o ka hematocrit ke hoʻonui i ka 4% o ka viscosity koko. E lilo kēia pilina i mea maʻalahi e like me ka piʻi ʻana o ka hematocrit. Ke piʻi ka hematocrit i 60 a i ʻole 70%, e hana pinepine ai i ka polycythemia hiki ke lilo ka viscosity koko e like me 10. ʻO ka manawa o ka wai, a ʻo kona kahe ʻana ma nā kīʻaha koko e hoʻopaneʻe nui ʻia ma muli o ka piʻi ʻana o ke kūʻē ʻana i ka kahe.He mea koʻikoʻi kēia i ka hypothermia, kahi e hoʻonui ai i ka viscosity koko e hoʻopilikia i ke kahe koko.
ʻO ke koʻikoʻi o ke kino
Ua hoʻopili kūʻokoʻa ʻia ka nui o nā mea pilikia cardiovascular maʻamau i ka viscosity koko holoʻokoʻa.
