Assessment of fetal heart rate and interpretation Flashcards
What does ISIA mean?
Intelligent Structured Intermittent Auscultation (in labour)
What is the normal heart rate range for a fetus?
110 - 160 BPM
What three things are considered ‘normal’ when auscultating?
110-160 BPM, a regular rhythm and accelerations, but no decelerations (compared to the baseline)
How often should IA be done in the first stage of labour?
Every 15 mins
How long should IA last for?
At least 1 min
When should IA be done when in labour?
Towards the end of a contraction
What is it important to palpate at the same time as IA?
Maternal pulse
Why is it important to palpate the maternal pulse during IA?
To ensure you differentiate between the maternal pulse and the fetus’ heartbeat
How often should you IA during the second stage of labour?
Every 5 mins
What three reasons would be cause for further action in relation to IA?
Decelerations, irregular rhythm, tachycardia accelerations
What may be happening to the fetus if the heart rate is gradually or abruptly decelerating?
Not coping and possibly developing hypoxia
What may be considered for ‘conservative management’ of an abnormal FHR?
More frequent IA, maternal position, hydration, vital signs and frequency of contractions
What three things should be done if an issue with FHR is confirmed?
Summon help, CTG monitoring and transfer to Obstetric led care
What should be done if no abnormal FHR found on CTG after 20 minutes?
Return to IA
