There is an assistant lung as one of utilization of artificial kidney for multi-purposes. Experimental and clinical studies in its gas exchanger were performed with coil type artificial kidney of EX-03 (membrane area: 0.84m2, Cuprophane membrane). Oxygenation method were liquid-membrane-blood diffusion for retaining of this function.
Its efficiencies for oxygenation showed as follows: PO2 was 221mmHg/200ml/min/0.84m2 for single flow, and PO2 was 343mmHg/200ml/min/0.84m2 for air-liquid flow in dialysate pass-ways. In this time, pressure gradients of PCO2 in in let and out let side of assistant lung showed 75mmHg/200ml/min/0.84m2 with 4.5ml/min of ultra-filtration rate.
Consequently, our experimental and clinical studies showed excellent results in carbonic acid gas exception than in oxygen addition.
