The Prompt Flex app offers midwifery trainees and trainers the ability to run a range of birthing scenarios relating to routine and difficult deliveries. In Drill mode, it allows each step or 'intervention' in the drill to be recorded along a timeline as it is performed, as well as recording the total time taken to deliver baby. Results can be attached to an email for later review and use as a debriefing tool. When used in conjunction with the Limbs & Things Prompt Flex Force Monitoring Bluetooth baby and birthing simulator, the app can also monitor the amount of traction being applied to the baby's head during a shoulder dystocia delivery. In Meter Mode trainees can learn how to avoid applying excessive traction to the baby's head outside of the context of a scenario. The force is displayed on a colour coded meter with a numerical readout in Newtons alongside. NB: Requires iPad 3 or above. Incompatible with iPad 2.
