CTG Quizziz

How are you feeling about your CTG knowledge and ability to assess associated fetal physiology?

• Unconfident

• I have some understanding

• I have a good understanding

• I'm going to offer to take over this lecture as my understanding is so good

​ (a)   ​ ​ react to compression-induced events in the fetal heart rate

• baroreceptors
• chemoreceptors

Which type of metabolism causes a build-up of lactate in the fetal circulation?

​ (a)   is insufficient oxygen to the fetal brain

• Hypoxia
• Hypoxaemia

On a CTG, what is considered a normal baseline?

• 110-160bpm

• 100-150bpm

• 130-180bpm

• 140-190bpm

Regarding accelerations, which of the following are correct statements?

• It is defined as a rise in the baseline by > 15 bpm for > 15 seconds

• An acceleration should start and return from a stable baseline

• An acceleration seen in the second stage of labour with a contraction is likely to indicate maternal heart rate

• The absence of accelerations in an antenatal trace is reassuring

Reorder the following in terms of least to most concerning type of deceleration in relation to underpinning fetal physiology

• Variable (with non concerning features)

• Early

• Late

• Prolonged

A late deceleration (commonly seen as a u shape on a trace) have a gradual onset and return to baseline. The importance of monitoring their presence in relation to ____________ is key

Label the following deceleration

b

Early

Late

Variable

Prolonged

Looking at the contractions on this trace, can you identify hyper-stimulation?
