Automatic patient deterioration and recovery

For pulseless/arrest rhythms (like VFib or Asystole), let vitals automatically get worse over time — SpO₂, EtCO₂, and BP falling — instead of staying wherever they were last set. Then, when the instructor delivers a successful shock or achieves effective pacing capture, have those vitals automatically recover, including EtCO₂ climbing back up to simulate return of a pulse.

This makes arrest scenarios feel alive instead of static: a student who delays treatment sees the real consequence (falling numbers) without the instructor manually adjusting sliders every few seconds, and a correct intervention is visibly rewarded with improvement.

This needs careful clinical input on the actual decay/recovery rates before it ships — getting them wrong (e.g. recovering too fast) could undersell the urgency of good compressions or a fast shock, which would teach the wrong lesson.
