  1. NICE clinical guidelines on intrapartum management [15] recommend monitoring every four hours in the first stage of labour, followed by every hour during the second stage. As the EXPEDITE study [11] did not stratify active labour by stage, to replicate this pattern we assumed that the second stage of labour stage would last no more than one hour, meaning one further examination would occur during this time
