CTG

Question 1

CTG assesses

Answer 1

foetal HR
variability
acclerations
decellerations
DRCBRAVADO

Question 2

Accelerations are…

Answer 2

an abrupt increase in the baseline foetal heart rate of greater than 15 bpm for greater than 15seconds.
They are reassuring.

Question 3

accelerations occuring alongside uterine contractions =

Answer 3

healthy foetus

Question 4

decellerations are..

Answer 4

an abrupt decrease in the baseline foetal heart rate of greater than 15 bpm for greater than 15 seconds.

Question 5

early decelleration =

Answer 5

begin at uterine contraction then stop - pressure increases vagal tone - so physiological.

Question 6

variable decelleration =

Answer 6

variable in duration and may have no relationship with contractions. Often caused by umbilical cord compression. Mother changing position may resolve.

Question 7

late decelleration =

Answer 7

begins at peak of the uterine contraction and recovers after contraction ends. This indicates insufficient blood flow to uterus and placenta > foetal hypoxia and acidosis > take foetal blood pH in case C-section is required!

Question 8

Prolonged decelleration =

Answer 8

deceleration lasting longer than three minutes. Foetal blood sampling/ C-section!
