The newly developed oxygenator "D702" is a compact hollow fiber membrane oxygenator with a priming volume of 170 ml. The maximum flow allowance is 4 liters per/minute. We used this oxygenator in 16 patients (11 infants and children, and 5 adults) undergoing various open heart surgery, and function of this oxygenator was studied. Pulsatile cardiopulmonary bypass was performed in 8 patients and nonpulsatile constant flow perfusion was employed in the remaining 8 patients. Our clinical experience showed excellent maintenance of PaO2 and PaCO2 during both pulsatile and constant flow bypasses. A low pressure drop was encountered across the membrane oxygenator, and therefore, this oxygenator is applicable for pulsatile cardiopulmonary bypass. The D702 is a very useful and applicable for a wide range of patients from infants to adults with a small body structure.
新研发的氧合器“D702”是一种紧凑型中空纤维膜氧合器，预充量为170毫升。最大流量允许值为每分钟4升。我们将此氧合器用于16例接受各种心脏直视手术的患者（11例婴幼儿和5例成人），并对该氧合器的功能进行了研究。8例患者采用搏动性体外循环，其余8例患者采用非搏动性恒流灌注。我们的临床经验表明，在搏动性和恒流旁路期间，PaO2和PaCO2均得到了良好维持。膜式氧合器的压力降较低，因此，该氧合器适用于搏动性体外循环。D702非常实用，适用于从小婴儿到体型较小的成人等广泛的患者群体。
