Arterial pressure: its role in perfusion and as a criterion of extracorporeal circulation adequacy.

abstract：:An apparatus has been contructed to regulate ultrafiltration accurately during dialysis. The principle of the apparatus is that, per unit of time, exactly the same amount of dialysate is introduced into the dialyzer as is discharged from it. The apparatus consists of two isovolumetric pumps connected in line. The four...
