Interpreting CTG
DRCBRAVADO
Define Risk
Contraction
Baseline Rate
Accelerations
Variability
Deceleration
Overall
Define and describe the different types of decelerations
- Early - Relative to contraction the deceleration is early. Normal because baby head is squeezed triggering vagal stimulation.
- Late - Pathological
- Variable - Cord compression. Cord is 2 arteries and 1 vein. When compressed vein compresses first and then arteries. When pressure released arteries rebound and then vein. The down and up nature of the graph depicts this.
