Hypoxemic and hyperoxemic episodes are common in newborns with respiratory disorders. We have developed a microprocessor-based data system for use with transcutaneous oxygen (TcPo2) monitors in an attempt to quantitate these episodes. The amount of time spent by an infant in each of ten preset TcPo2 ranges can be automatically recorded. These data are referred to as the oxygram. Fourteen newborn infants were monitored for a total of 552 hours using this system. They spent a mean of 2.96% of the time with a TcPo2 less than or equal to 40 torr and 0.26% of the time with a TcPo2 greater than 100 torr. Representative oxygrams are presented. Clinical and research applications of the data system are discussed.
