Dianne, I agree with you, respiration often causes variability in the
Spectral Doppler trace. More often than not though, I find that the
adjacent waveforms have little resemblance to each other.
I've observed regular Spectral Doppler trace changes more commonly in
fetuses with premature atrial contractions.
With many kind regards,

For Ruth,
I agree with allen on most things about the sonohysterogram.
The neutral uterus does need a transabdominal manual pressure to get it in
line or
in view of the ultrasound field. Infact to decrease costs we use infant
feeding tubes of larger calibre for most of our studies - the ones in which
we have a leak we use the balloon cathetor.
Slight pressure from the probe also helps in getting better views.
