YIYutaka Igarashi TNTATSUYA NORII HNHatsumi Nakanisi

Key Points

This study aims to understand how the duration of airway obstruction impacts health outcomes.
Analyzed data from the MOCHI registry
Followed a nationwide cohort of cases with foreign body airway obstruction
Measured time of airway obstruction and related outcomes
Outcomes worsened continuously with each minute of unresolved obstruction
No safe time window for intervention was identified
Immediate bystander intervention is critical for improving prognosis

Abstract

Outcomes declined continuously per minute of unresolved obstruction, with no inflection point or "safe" time window. This highlights that every minute of delay worsens prognosis, reinforcing the need for immediate bystander intervention.
