Smartwatch fall detection witnesses OHCA
Wearable saving lives: a case report
Resuscitation Plus · Added 26 August 2026
Case report demonstrating that smartwatch fall detection can serve as a digital witness in unwitnessed out-of-hospital cardiac arrest, triggering alerts that enabled timely CPR initiation and resulted in favourable neurological recovery.
- Study type
- Case series
- Design
- Case report
- Participants
- 1 man, 69, with unwitnessed OHCA while running
- Main finding
- Smartwatch fall detection triggered automated alerts; CPR started ~6-7 min after collapse; VF was initial rhythm, ROSC achieved, discharged day 29 with complete neurological recovery
- Caveat
- Single case; no evidence of generalisable benefit
- Bottom line
- Hypothesis-generating
Why it matters in Australia (High relevance). Commercial wearable technology is widely available in the community, and EMS personnel increasingly encounter patients with smartwatches triggering alerts — understanding this workflow improves response coordination and outcomes.
Learning goal
Build my understanding of how wearable alert technology can support earlier bystander response to unwitnessed cardiac arrest.

Persistent OHCA inequality across England
Retrospective analysis of 165,701 OHCA patients in England 2018–23 found 23.6% of postcode districts remain high-risk (higher OHCA incidence, lower bystander CPR rates), with urban deprived areas showing 71.2% BCPR versus 79.1% in low-risk areas, though ROSC and survival were slightly higher in high-risk areas.

Kidney biomarkers predict outcomes after OHCA
Prospective study of 82 comatose OHCA patients found kidney-specific biomarkers (plasma and urinary NGAL and KIM-1, cystatin C) were superior to serum creatinine for early AKI detection and prediction of poor neurological outcomes at discharge.

MRI profiles of postanoxic status epilepticus
Two-center study of 192 postanoxic patients using quantitative MRI found postanoxic status epilepticus exhibited more favorable hypoxic-ischemic brain injury profiles (higher whole-brain ADC values) compared with generalized periodic discharges or malignant EEG patterns.
