The most dreaded sound during labor is a drop in the fetal heartbeat that does not come back up. Nursing measures are turning patient to her side, giving the mother oxygen by facemask, increasing the IV fluid rate and doing a exam to be sure there is not a prolapsed cord. Sometimes tickling the top of the baby's head will cause the heartbeat to come back up. If these measures do not work and the heartbeat stays down, it is time to move FAST to surgery for an emergency C-section. Triggers for your sounds will show up on your avi list and are: Normal fetal heartbeat "fhb" fetal heartbeat deceleration "decel" and newborn cry "baby cry". You can use this as a patient to send your nurse running in FAST if she hears the heartbeat drop. Or use it as doctor or nurse to bring realism to your patients experience with a fetal heartrate decel once in awhile. By Genesis!
