PLACENTA AND UMBILICAL CORD
The PD1 / PD1+ may be used to locate the position of the placenta,
thus aiding in the early diagnosis of placenta praevia or
eliminating placental site where amniocentesis is to be performed.
The sound from the placenta is an indistinct swishing, caused
by bloodflow in many vessels. There is no distinct beat pattern
to the sound.
The vessels of the umbilical cord give rise to a higher pitched
sound than the normal fetal heart, with pulsations at the fetal rate.
PD1+ FETAL HEART RATE RECORDING
The optional UltraTrace2 software runs under Windows XP
and provides a fetal monitor style real time chart recording
and patient database where the traces can be printed on
most Windows supported printers.
Details of the use of UltraTrace2 are included in the
UltraTrace2 operating manual.
