during emergency treatment, the automated external defibrillator (aed) is known as a "life-saving device." however, a recent incident in haikou, hainan, has aroused public concern about its ease of use.a man suddenly fell ill, and the people around him found that the aed needed to be scanned with a code before it could be opened and used. due to the network signal on that day, the code could not be scanned successfully.

in an emergency, should there be a threshold for the "life-saving device"? the state stipulates that aeds should be easy to open, so why are there still cases where aeds are locked and sealed?

if you want to use aed for emergency treatment, you need to scan the code to open it.

recently, someone filmed a video showing a man suddenly falling to the ground in the waiting room of haikou west bus station, with many people around trying to rescue him. the camera then turned to the aed next to him, and the door of the cabinet that sealed the aed could only be opened by scanning the qr code via wechat.

the person who shot the video said that due to poor network signals at the time, the device did not respond after scanning the code and the operation was delayed.

wu yuandong, a staff member of haikou city 120 emergency center who is responsible for providing guidance for the equipment, told reporters:the patient who collapsed that day had an epileptic seizure and did not suffer from cardiac arrest, so an aed was not required."the patient had a slight convulsion and then fell to the ground, but he was not unconscious and did not have cardiac arrest. 120 also rushed to the scene at this time. he recovered after more than ten minutes. no cardiac compression was performed at the scene. the patient left by himself in a car."

an automated external defibrillator, or aed, enables non-professionals to perform defibrillation and cpr on patients experiencing cardiac arrest.after cardiac arrest occurs, the best rescue time is the "golden 4 minutes". defibrillation during this period can greatly reduce the risk of sudden death of the patient.therefore, aed is also called a "life-saving device."

data shows thatthe national red cross system has deployed more than 65,000 aeds in public places and has provided training on the use of aeds to more than 15.26 million people in the past five years.

wu yuandong said that the aed equipment at the passenger station had been installed for a long time. to ensure the safety of the equipment, it was designed for real-name authentication at the time, and it was necessary to scan the code for authorization and authentication. however, a detail not shown in the online video is that there is a safety hammer on the side of the equipment.under the condition of smooth signal, we tested that it can usually be opened within 15-20 seconds.due to different environments, the base station signal strength is inconsistent.if the code scanning fails, other auxiliary measures can be used - safety hammer.”

the reporter found that the general office of the national health commission issued the "notice on the guidelines for the configuration of automatic external defibrillators in public places (trial)" in december 2021, whichit is required that the aed outer box or cabinet door should be easy and quick to open (without locking or scanning codes) to avoid missing rescue time.

wu yuandong told reporters that the equipment appearing in the video had been deployed at haikou west bus station before the relevant "notice" was issued in 2021, and the rectification has not yet been completed.currently, this device has been replaced by a device that does not require code scanning, and such devices will be gradually replaced in the future.

to prevent the loss of aed

some areas are directly locked

people found thatthere are many aed devices in various places that require scanning codes to use, and some aed devices are even locked directly to prevent loss.previously, prosecutor zhou hao and his colleagues from the shangcheng district people's procuratorate of hangzhou city, zhejiang province discovered such problems.

zhou hao said that around 2022, a staff member found an aed station in the community and tried to open it but found that the aed was locked.to use the aed, one must scan the code to download the company app indicated on the box, and use the app to call the first responder next to the station to open the box."we did an experiment at the time and found that the whole process from scanning the code to downloading to calling for help and unpacking the device exceeded the golden rescue time of 4 minutes."

subsequently, the shangcheng district procuratorate issued a pre-trial prosecution recommendation to the relevant competent departments, requiring them to rectify the problems with the standardized configuration of aeds.

so, if it takes 15-20 seconds to scan the aed code and turn it on, what impact will it have on rescue?

wang jiangang from the science, education and training section of hangzhou emergency center said:after the aed device is turned on, untrained personnel need to operate step by step according to the voice prompts. every second is important.this is also the reason why the country requires aed equipment to not be locked in 2021.

“for cardiac arrest patients, time is of the essence.for every minute of delay in rescue, the success rate of resuscitation decreases by 10%.if you wait 10 minutes to try to save the patient, there is almost no chance of survival, and even if he is resuscitated, he may be brain dead," wang jiangang stressed.

wang jiangang told reporters that hangzhou had previously had companies providing aeds for free that required scanning a qr code to use, but as regulations were improved, these devices have been replaced.currently, a more scientific storage method is used, including raising the height of the aed to prevent children from accidentally touching it, sealing it with adhesive strips, and providing sound and light reminders after opening.this not only protects the device, but also makes it more convenient to use.

⚪ use seals: use easy-pull seals on the aed box, which can be opened with just force. the seal is marked with "do not open the box unless it is an emergency."

⚪open the aed box to activate the luminous and audible alarm device: to remind people around that there is an emergency and call for more people to come to help, and it can also warn those who operate it incorrectly.

⚪install the aed at a height of 1.5 meters to prevent children from accidentally touching it.
