Table 2 Participant scenario variables

From: A pilot exploratory investigation on pregnant women’s views regarding STan fetal monitoring technology

Variables compared across scenarios CTG scenario STan scenario
External fetal monitoring method Two discs (transducers) rest on mother’s stomach, one disc measures heartbeat and other disc monitors contractions. Not available.
Internal fetal monitoring method. Electrode inserted through woman’s vagina, and attached to unborn baby’s scalp. Lead is attached to mother’s thigh. Only fetal scalp electrode can be used. Electrode inserted through woman’s vagina, and attached to unborn baby’s scalp. Lead is attached to mother’s thigh.
Movement during labour and contractions. Abdominal belt: can stand, and move within a two-metre radius (length of cord connecting woman to monitor). Or, if using scalp electrode, must lay flat on bed. Restricted mobility because need to be connected up to STan monitor. Mostly confined to bed.
Delivery associated with each technology. Increased chance of operative intervention including caesarean section. Decreased chance of operative intervention including caesarean section.
