I have the Spectro2. It has an adult probe, but you can purchase the neonatal. When I purchased mine from Smith Medical they were running a special that included the neonatal reusable sensor for free.
Spoke with a Hopkins rep at the ACNM convention and they are getting ready to launch a much smaller version of the pulse ox. It will be aimed at OOH midwives and can be used for neonatal resuscitation but more importantly for the CCHD screenings.
BTW: I think the number of states where CCHD screening is now mandatory (for hospitals) is up to 10. Several other states also have bills and regulations in review. Considering CCHD affects 1:100 babies and the screening is simple, and, and non invasive, it is something we can easily offer OOH also.
