Q

What is the neumonic VEAL:CHOP

A

Variable decelerations means that there is cord compression
Early decelerations means that there is head compression
Accelerations means that the baby’s overall well being is good and they are well oxygenated
Late decelerations means that there is placental insufficiency and they do not have oxygen
