A pulse oximeter will be placed on the infant’s extremity, preferably the right hand. The data stored in the oximeter will be retrieved and the data points kept as a file. These data points represent the SaO2 every 2 seconds during the monitored period. The resuscitation teams will utilize the pulse oximeter to determine if additional oxygen is required and to evaluate the effectiveness of resuscitation. In addition, we will review the data collected by the pulse oximeter to observe the change in SaO2 with delivery and resuscitation.
