What was the main finding regarding the time difference between cutting clothing with scissors and lifting clothing aside when laypeople used an AED in the Niigata University of Health and Welfare study?

The study found that cutting clothing with scissors delayed the delivery of the electric shock by approximately 24 seconds compared with simply lifting or moving the clothing aside, demonstrating a measurable time disadvantage for the cutting method.

Who were the researchers and student participants involved in the randomized simulation study on AED use conducted by Niigata University of Health and Welfare?

The research team consisted of Associate Professor Kentaro Omatsu, Lecturer Gen Toyama, Professor Yutaka Takei, fourth‑year students Reishin Matsuyama, Neneka Kamitani, Genjiro Muro, Azusa Tsunemoto, and graduate student Eiji Hori, who together supervised and participated in the simulation.

On what date and in which peer‑reviewed journal were the findings of the Niigata University of Health and Welfare AED clothing removal study officially published?

The findings were officially published on March 13, 2026 in the European Resuscitation Council’s international journal titled “Resuscitation Plus,” providing a scholarly record of the observed 24‑second timing difference.

How many university students participated in the simulation, and what level of prior medical‑professional resuscitation training did they have according to the study description?

Forty university students without any prior medical‑professional‑level resuscitation training took part in the simulation, ensuring that the participants represented typical laypersons who might encounter a cardiac arrest scenario.

Why is rapid defibrillation emphasized in cardiac‑arrest survival, and what specific recommendation regarding clothing does the study highlight for layperson AED use?

Rapid defibrillation is critical because survival rates decline sharply without early shock, and the study highlights the recommendation that laypersons should remove any obstructive clothing, preferably by lifting rather than cutting, to minimize delay in delivering the electric shock.

[Niigata University of Health and Welfare] 24-Second Difference in Delivering Electric Shock: "Cutting" vs. "Lifting" Clothing When Using an AED – A Study Simulating AED Use by the General Public

NQ Score 50/100

AI Summary (NQ-processed)

A research group at Niigata University of Health and Welfare conducted a simulation study to examine how clothing removal methods affect the time taken for laypeople to deliver an electric shock via an AED. The study found that using scissors to cut clothing resulted in a 24-second delay compared to simply lifting or moving the clothing aside. These findings suggest a need to re-evaluate how AED training addresses clothing removal.
