Abstract

A mass spectrometer blood gas catheter system for the continuous in vivo analysis of Po2 and Pco2 has been presented. This system has been experimentally evaluated and demonstrated to be reliable and reproducible over a period of 30 hr following insertion of the catheter in the abdominal aorta. Although the present catheter design does not allow insertion through an existing umbilical arterial line in neonates, a clinical evaluation will be undertaken when a more flexible catheter becomes available.

摘要

已推出一种用于体内连续分析Po2和Pco2的质谱仪血气导管系统。该系统已通过实验评估，并证明在将导管插入腹主动脉后的30小时内是可靠且可重复的。尽管目前的导管设计不允许通过新生儿现有的脐动脉导管插入，但当有更灵活的导管可用时，将进行临床评估。
