Hi Babushka Doll
It is very common for your baby’s heart rate to go up for a short time. As Trish said is usually when they are moving but it can happen at other times as well, for example during a BH contraction. I have seen the heart rate go way higher than 184 without any problems. If I was checking your baby’s heart rate and it was 184 I would also leave the doppler on a little longer to see that the rate is changing and if it went down to 176 I would be quite happy with that. But I would have told you why I left the doppler on a little longer.
