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.

Simulation is the foundation of high quality medical education. I made this app so that sim could be freely available to all, without breaking the bank. Any device can be the controller or the monitor. Use the same login, or share a session, and the vitals update straight away. Beeps included! The control panel allows you to manipulate the scenario to suit your needs: - Adjust HR, BP, CO2, RR, BIS reading - Trigger cardiac arrest - Adjust the cardiac rhythm - Run through pre-build scenarios which automatically adjust the vitals - Talking points for discussion and Links to resources for further discussion Terms and Conditions: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
