About this study
Official title: Out-of-Hospital Cardiac Arrest Care Through Empowered and Equipped Community First Responders: Mobile External Defibrillation Investigation for Cardiac Arrest in Singapore (MEDICS).
The goal of this clinical trial is to learn the feasibility of equipping the volunteer community responders (VCR) with the mobile external automated defibrillators (mAEDs) for the management of adults experiencing out-of-hospital cardiac arrest (OHCA) patients. It will also provide early signals if this enhanced system can help increase the frequency of defibrillation and doing it earlier. The main questions it aims to answer are:
- Can equipped VCRs apply mAEDs more frequently and earlier to potentially get more patients successfully resuscitated?
- Is this system enhancement is feasible in the long run.

Participants, the VCRs, will:
- Carry a 450 gm mAED with them all the time for up to an year and use it on an OHCA patient if and when alerted to help.
- They will hand over this single-use battery-operated device to the EMS crew for data retrieval and potential replacement
- They will be interviewed for their experience of being equipped and use of the mAED.
