Public-access defibrillation location effects in Yokohama

Location-resolved performance of public-access defibrillation in an urban EMS system: a population-based study in Yokohama, Japan
Resuscitation Plus · Added 11 August 2026

Population-based study of public-access defibrillation performance across different locations in urban Yokohama, Japan

Study type

Registry

Design

Retrospective population-based registry study with propensity score matching

Participants

15,345 OHCA patients in Yokohama, Japan, 2021–2024 (272 received PAD shock)

Main finding

PAD shock associated with favourable 30-day neurological outcome (OR 3.3; 95% CI 1.9–5.7) and 30-day survival (OR 3.7; 95% CI 2.2–6.1); shock rates varied by location from 34% at sports facilities to 0.06% at private residences

Caveat

Japanese urban setting; very few PAD shocks overall, and residual confounding possible despite matching

Bottom line

Context only

Learning goal

Understand how location influences public-access defibrillation use and outcomes in out-of-hospital cardiac arrest.

• No risky oxygen build-up at defibrillation site in CPR

  Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine · 12 Aug 2026 · Simulation · Hypothesis-generating

  Mannequin study testing whether removing oxygen-delivery devices reduces ambient oxygen concentration at defibrillation sites — it found no clinically relevant oxygen accumulation, and removing devices made no difference to oxygen levels.

• Smaller bags worse for CPR ventilation

  Resuscitation Plus · 9 Aug 2026 · Systematic review · Supports current practice

  Systematic review testing whether smaller self-inflating bags improve CPR outcomes — they found limited very-low-certainty evidence suggesting smaller bags (450-700mL) were associated with lower survival with favourable neuro outcomes compared to standard adult bags (1000-1685mL).

• Calcium in in-hospital arrest linked to worse outcomes

  Resuscitation Plus · 9 Aug 2026 · Cohort · Context only

  Retrospective cohort study of 599 in-hospital cardiac arrest patients testing whether calcium administration improves outcomes — calcium was associated with significantly lower rates of sustained ROSC, survival to discharge, and favourable neuro outcomes.

• Ultrasound maps CPR hand position over LVOT not iAMC

  Resuscitation · 9 Aug 2026 · Cross-sectional · Hypothesis-generating

  Prospective observational study using transthoracic echocardiography to map optimal chest compression location — guideline-recommended hand placement frequently overlies the left ventricular outflow tract rather than the ideal area of maximal compression.
