Why Every Condo and HDB Block Should Have an AED

Most out-of-hospital cardiac arrests in Singapore do not happen in malls or MRT stations.

They happen at home.

That single fact changes where AEDs need to be. If the collapse is in a flat on the 12th floor of an HDB block or inside a condo unit, a device three streets away at a shopping centre is the wrong plan.

The defibrillator has to be reachable in the same minutes when CPR still has a chance.

What the Singapore OHCA data shows

Singapore’s national picture comes from the Singapore Out-of-Hospital Cardiac Arrest Data Report (2011–2021), published by the Unit for Pre-hospital Emergency Care (UPEC) with partners including SCDF and the Singapore Heart Foundation. The report draws on the Singapore arm of the Pan-Asian Resuscitation Outcomes Study (PAROS) registry.

Key figures from the latest edition:

  • Case counts are rising. OHCA cases increased from 3,432 in 2020 to 3,637 in 2021. The report attributes the rise largely to Singapore’s ageing population. Age is a major risk factor for cardiac arrest.
  • Incidence is rising too. Crude incidence climbed from 60.4 per 100,000 people in 2020 to 66.7 per 100,000 in 2021. Age-standardised incidence rose from 43.3 to 45.8 per 100,000 over the same year.
  • Most arrests are residential. In 2021, 79.5% of cardiac arrests occurred in the home. Earlier editions of the same reporting programme consistently put home arrests around 70%. The location has not flipped to public venues.
  • Bystander AED use is still low. AEDs were applied in 9.5% of cases in 2021 (up slightly from 8.5% in 2020). UPEC’s stated challenge is to push utilisation beyond 20%.
  • Survival remains hard. Overall survival-to-discharge was 3.8% in 2021. Utstein survival (witnessed, shockable, presumed cardiac) was 19.9%. Of those who did survive, 79.3% had good-to-moderate neurological function.

Earlier years in the same report series already showed the climb: about 2,972 cases in 2018 and 3,233 in 2019, then 3,432 and 3,637. The direction is clear even before you adjust for population growth.

A decade of system work has improved outcomes from the single-digit survival era. A 2021 Singapore Medical Journal review of Singapore’s OHCA response, using PAROS data, reported overall survival-to-discharge rising from 3.5% to 5.9% and Utstein survival from 11.6% to 25.9% between 2011 and 2018. Progress is real. Coverage in residential blocks is still the gap that matches where people actually arrest.

Why home arrests make block-level AEDs non-negotiable

When someone collapses in a living room, the first person on scene is usually a family member, neighbour, or domestic helper, not a mall security officer standing next to a wall cabinet.

Every floor of travel, every wrong lift lobby, and every locked side gate burns the same resource: time. Early CPR keeps some blood moving. Early defibrillation treats shockable rhythms before they deteriorate. The UPEC report cites a systematic review and meta-analysis (Holmberg et al., Resuscitation, 2017) concluding that early bystander AED use can more than double survival after OHCA.

That multiplier only works if a device exists within a realistic run from the flat. “Somewhere in the neighbourhood” is not the same as “at the lift lobby of this block.”

Singapore’s Save-A-Life and residential public-access defibrillation efforts were built around this geography: put AEDs where people live, register them nationally, and surface them through myResponder. The medical logic is not contested. The operational question for each MCST and Town Council is whether this block is covered, maintained, and known to residents.

Condo vs HDB: same medical problem, different logistics

HDB estates often share devices across nearby blocks (for example, one cabinet covering paired blocks under Save-A-Life style deployments). Coverage can look dense on a map and still feel far when you are on a high floor with a delayed lift.

Condos and private apartments depend on the MCST. Some install AEDs at the guardhouse, clubhouse, or lift lobby. Others assume the nearest mall device is “close enough.” After hours, condo AEDs may be reachable via 24-hour security even when club facilities are closed. That only helps if security knows where the kit is and residents know to ask.

In both settings, the failure modes rhyme:

  • No device on the premises
  • Device present but expired pads or flat battery
  • Device behind a locked room nobody can open at 2 a.m.
  • Residents who have never noticed the cabinet
  • Runners sent to the wrong block because the landmark was never briefed

Public listings help planning. AEDLocator mirrors SCDF open data so you can see floor text and hours for registered public-access devices. In a live emergency, call 995 and use myResponder. Read opening hours and access before you trust a pin at night.

What “have an AED” should mean for a block

Installing a box is step one. A residential AED programme that actually works usually includes:

  1. A known location at a lift lobby, guard post, or other 24-hour accessible point, with clear signage
  2. Registration in the national public-access AED dataset so dispatch and myResponder can find it
  3. Maintenance for pads, batteries, and readiness checks on a calendar, not by hope
  4. Resident awareness: AGM slides, lift notices, WhatsApp blast, and a walk-past for new movers
  5. A runner protocol: who fetches the kit while someone else stays on 995 and starts CPR

If you manage a condo, put AED ownership on the same footing as fire extinguishers and first-aid boxes. If you live in an HDB block without a nearby cabinet, raise it with the Town Council or Residents’ Committee and check neighbouring blocks on where AEDs are commonly found.

What residents should do even before the next cabinet arrives

Call 995 for unresponsive people who are not breathing normally. Start CPR if you can. Send someone for the nearest AED. Details: what to do before an ambulance arrives and how to use an AED.

Register as a community first responder on myResponder. SCDF’s 2025 EMS statistics note that, as of end-November 2025, 160 cardiac arrest victims had been saved by community first responders alerted through the app, with more than 250,000 CFRs registered since launch. Volunteer arrival is how residential AED application actually rises.

Learn the difference between a heart attack and cardiac arrest so you do not fetch a defibrillator for every chest pain episode, or freeze when the person has already collapsed: cardiac arrest vs heart attack.

The honest limits of the argument

An AED on every block will not make overall survival 50%. Many OHCA rhythms are not shockable. Ageing drives incidence up even when systems improve. Pads expire. Cabinets get blocked by renovation debris. Bystanders still hesitate.

Those limits do not weaken the residential case. They sharpen it. With roughly four in five arrests at home, and national bystander AED application still under 10%, the highest-leverage community investment is a maintained device within a short indoor run of where people sleep, plus neighbours willing to use it.

FAQ: residential AEDs in Singapore

Do most cardiac arrests in Singapore really happen at home?

Yes. The UPEC Singapore Out-of-Hospital Cardiac Arrest Report 2011–2021 states that 79.5% of OHCAs in 2021 occurred in the home. Earlier reports in the series put the home share near 70%.

Is OHCA becoming more common here?

Case counts and crude incidence rose in the latest reported years (3,432 cases and 60.4 per 100,000 in 2020; 3,637 and 66.7 per 100,000 in 2021), with ageing cited as a major driver. Treat the annual reports as the authoritative local source rather than informal estimates.

If my block already has an AED, is that enough?

Only if people can reach it, pads and batteries are current, and residents know where it is. Register it nationally, brief security, and walk the route once. Unknown or locked devices do not count in the minutes that matter.

Where can I check for a public AED near my block?
