Canadian scientists say they have By helping people to literally exhale the alcohol in the system, a new method was found to treat potentially life-threatening alcoholism.Their equipment, this is the designed can make people hyperventilate safely and was found to speed up the removal of alcohol by healthy volunteers three times faster In a small experimental study.

Usually, toxins such as alcohol are broken down by the liver to a large extent.The liver can be punished a lot, but the rate at which it metabolizes alcohol is constant, which means You can’t speed up the process When the amount of alcohol in your body is fatal or severely harmful. In most cases, when someone faints, all doctors can do is to ensure that their breathing and body functions are stable until the liver can do its job.

But the lungs will also play Small role Naturally eliminate alcohol from our body, if you have ever smelled someone’s breath drunk, you may have noticed. This happens when alcohol-filled blood reaches the lungs to replenish fresh oxygen. Some alcohol in the blood, Together with carbon dioxide, Then called out.

This process can be accelerated by hyperventilation or rapid breathing.The trouble is When we hyperventilate, we also lose too much carbon dioxide. In order to prevent this from happening, when we hyperventilate for too long, our body will become severely unwell and even lose consciousness (this is why some people are obviously panicked).

According to the study author and inventor Joseph Fisher (Joseph Fisher), The device has found a way to interrupt this trigger while keeping personnel safe. The patient is equipped with a gas mask, which is connected to a supply of oxygen and carbon dioxide. The mixed gas they inhale will cause them to hyperventilate, and the device will feed them back enough carbon dioxide so that the body does not vent unconsciously.

“It is designed to allow the normal amount of carbon dioxide to escape each time you breathe, and any excess carbon dioxide will return on the next breath.” Said Fisher, an anesthesiologist and senior researcher at the University of Toronto Medical Network In the email. “All of this is done in a simple way with mechanical valves, so it’s sillyProof—no electronics or computers required. “

have a test Fisher and his team recruited five healthy volunteers to make them mildly intoxicated (the drink chosen was 80-Vodka is mixed with 500 ml of water). In a two-day series of experiments, they were monitored when they sobered up naturally and used the device for half an hour. Throughout the experiment, their alcohol content was measured with a breathalyzer and blood samples.Compared with natural methods, volunteers appear three times more sober Faster when breathing equipment.

What the team found was Published In about Thursday.

Although the study sample is very small, which means that the results should be observed with caution, the device itself has not been tested.Just last year, FisherThornhill Medical was founded and won Marketing approval The device (trademark ClearMate) is provided by the US Food and Drug Administration (FDA) and is used in emergency rooms in the United States to treat carbon monoxide poisoning.Fisher said the same device may be used to treat both diseases in the future, including more toxic forms of alcoholism, such as Consumer Windshield washer fluid (methanol) or pirated wine (polyethylene glycol).

According to Fisher, the basic facts Our lungs help remove Alcohol in our bodies has existed for nearly a century. But he is not sure why no one has thought of trying to use this process so far.

He said: “This method is so simple and obvious that no one realizes its potential even if one observes it.” “Hidden in full view. I don’t know how to explain it.”

Although conscious alcoholism patients can use this device safely, it is not faint, While still being safe for medical staff. Fisher said: “The higher the concentration of alcohol in the blood, the more effective the method.” “If the patient loses consciousness, a catheter can be placed in the lung to protect the patient’s breathing, and then the method can be applied manually.”

Although ClearMThe equipment used won the FDA Approval of carbon monoxide poisoning, more Need data Because it is believed to treat alcoholism. To this end, Fisher and his team hope that other researchers will be willing to actually test the device,World settings, Such as emergency room and intensive care unit, And publish your findings.
