The differentiation between umbilical artery and vein, specifically during the resuscitation procedure, is clinically neither always easy nor unambiguous. A preterm infant of 35 weeks of gestational age was born after an uneventful course of his mother's(More)
The prototype of a microprocessor controlled oxygen uptake monitor oxyconsumeter developed by Draegerwerk AG, Luebeck, FRG, has been tested. The measuring accuracy of this device was assessed with laboratory bench experiments utilizing both the nitrogen dilution technique and the hydrogen combustion technique to simulate oxygen uptake (VO2). The correlation(More)
