Ropa Muenzaniso Kuunganidzwa Heparin Tube
Tsanangudzo Pfupi:
Heparin Ropa Rinounganidza Machubhu ane green top uye ane spray-dried lithium,sodium kana ammonium heparin pamadziro emukati uye anoshandiswa mukiriniki chemistry, immunology uye serology.The anticoagulant heparin activate antithrombin, inovharira kugwamba kweropa uye nokudaro inoburitsa yakazara. ropa/plasma sampuli.
Hemorheology, zvakare inopereterwa hemorheology (kubva muchiGiriki 'αἷμα,haima'ropa' uye rheology, kubva muchiGiriki ῥέωrhéō,'kuyerera' uye -λoγία,-logia'study of'), kana rheology yeropa, chidzidzo chekuyerera kweropa nezvinhu zvaro zve plasma nemasero. Kupfapfaidza kwematishu kwakanaka kunogona kuitika chete kana maitiro eropa ari mukati memamwe mazinga. Ropa viscosity inotarirwa neplasma viscosity, hematocrit (chikamu chechikamu chemasero matsvuku eropa, ayo anoumba 99.9% yemasero emagetsi) uye michina yemasero matsvuku eropa. mazwi erythrocyte deformability uye erythrocyte aggregation.Nekuda kweizvozvo, ropa rinoita senge risiri reNewtonian fluid.Sezvo, viscosity yeropa inosiyana neshear rate.Ropa rinova risinganyanyi kutaridzika pakuveura kwepamusoro seavo vanosangana nekuwedzera kuyerera senge panguva yekurovedza muviri. kana mupeak-systole.Saka, ropa imvura inocheka-shear-thinning fluid.Kupesana, viscosity yeropa inowedzera apo shear rate inodzika nekuwedzera kwemudziyo madhayamita kana nekuyerera kwakaderera, sekudzika kubva kune chivharo kana mu diastole.Ropa viscosity inowedzerawo ne kuwedzera mured cell aggregability.
Ropa viscosity
Ropa viscosity chiyero chekudzivirira kweropa kuyerera.Inogonawo kutsanangurwa sekukora uye kunamatira kweropa.Iyi biophysical pfuma inoita kuti ive yakakosha gadziriso yekukweshana kumadziro emidziyo, chiyero chekudzoka kwevenous, basa rinodiwa kuti moyo upombe ropa, uye kuti okisijeni yakawanda sei inotakurwa kuenda kumatishu uye nhengo.Aya mabasa emwoyo nevascular system ane hukama zvakananga nevascular resistance, preload, afterload, uye perfusion, zvakateerana.
Izvo zvinonyanya kukosha zveviscosity yeropa ndeye hematocrit, tsvuku tsvuku yeropa deformability, red blood cell aggregation, uye plasma viscosity.Plasma's viscosity inotarirwa nehuwandu hwemvura uye macromolecular components, saka izvi zvinokanganisa viscosity yeropa ndeye plasma protein concentration nemhando dze mapuroteni ari plasma.Kunyange zvakadaro, hematocrit ine simba rakasimba pane rose viscosity yeropa.Chimwe chikwata chekuwedzera muhematocrit chinogona kukonzera kuwedzera kwe4% muropa viscosity.Ukama uhwu hunowedzera kunzwisisika sezvo hematocrit inowedzera.Apo hematocrit inokwira kusvika ku60 kana 70%, iyo inowanzoita mu polycythemiathe viscosity yeropa inogona kuva yakakura se10 nguva iyo yemvura, uye kuyerera kwayo mutsinga dzeropa kunononoka zvikuru nekuda kwekuwedzera kwekudzivirira kuyerera.Izvi zvinozoita kuti kuderedzwa kweokisijeni,Zvimwe zvinhu zvinokonzera viscosity yeropa zvinosanganisira tembiricha, apo kuwedzera kwekushisa kunoguma nekuderera kweviscosity.Izvi zvinonyanya kukosha mu hypothermia, uko kuwedzera kweropa viscosity kunokonzera matambudziko nekutenderera kweropa.
Clinical kukosha
Zvizhinji zvakajairwa zvenjodzi yemoyo zvakabatanidzwa zvakazvimiririra kune rose viscosity yeropa.
