Canadian researchers say ‘hyperventilating’ may help combat alcohol poisoning – Global News
Canadian researchers say they’ve developed a game-changing method to treat alcohol poisoning — and it involves literally breathing alcohol out of the body by hyperventilating.
They say it’s three times faster than relying on the liver alone.
Lead researcher Joseph Fisher, a senior scientist at University Health Network’s Toronto General Hospital Research Institute, calls the technique a “no-brainer” that doesn’t have side effects and involves a very simple mechanical device to assist breathing.

He says the process simply takes advantage of the fact that each exhalation, along with carbon dioxide, contains alcohol that has evaporated from the blood into the lungs.
“And the more breaths you take, the more evaporates. It’s that simple,” says Fisher.
Of course hyperventilating causes its own issues — including light-headedness, tingling or numbness on hands and feet, and fainting.
Fisher’s approach relies on a device that administers the exact amount of carbon dioxide needed to maintain normal levels in the blood.
It’s the size of a small briefcase and uses a valve system, connecting tubes, a mask, and a small tank with compressed carbon dioxide.
Fisher says a small study involving five male volunteers proved the concept works, but more extensive clinical trials are needed.
He hopes it could one day serve as a powerful tool in any hospital emergency department.
“I used to be an emergency doc and I know they have big issues with patients who — on top of everything else — are also alcohol-intoxicated,” says Fisher.
“Many of them, you don’t know what’s wrong with them. They’re coming in unconscious and highly alcohol-intoxicated so they’re hard to examine…. And there’s nothing you can do. You have to wait until their livers metabolize it.”
The study was released Thursday in the peer-reviewed journal Scientific Reports, published by Nature Research.
Subjects each drank about half a glass of vodka and were able to eliminate alcohol three times faster than through the liver alone, says Fisher.
He says the approach is as effective as using a hyperbaric chamber, a much more involved set-up that delivers oxygen in a pressurized room or chamber.
Years ago, Fisher developed similar techniques to address carbon monoxide poisoning and eliminate anesthetics from the body.
He says he discounted the possibility hyperventilation could also be used to treat alcohol poisoning until about two years ago when a colleague suggested it.
Now, Fisher wonders if there are more ways to use the method.
“This is why my armpits are sweating — (it could save) the little kid that gets into the laundry room and drinks one of the solvents or something like that. Usually those kids are down for the count but this may be an approach,” he says, also musing on treating survivors of a fire who may have inhaled toxins.
“I think it opens up a number of areas that people can look at to get rid of.”
As it stands, there is no treatment for alcohol intoxication, and there is no way to speed up the rate at which the liver works to clear alcohol from the body.
Fisher says the technique is especially efficient if intoxication is high, making it less useful after a casual night of drinking, for instance.
Nor does he recommend people try to hyperventilate on their own. The treatment is really designed for severe cases that can be life-threatening or endanger organs such as the liver or brain.
Dr. Laurent Brochard, a critical care physician and scientist at St. Michael’s Hospital, says the technique is “very smart” but agrees it requires real-world testing.
“A guy who is drunk, it may be difficult even to put the mask on the face,” says Brochard, adding that if the patient has ingested other drugs, that might further complicate care.
“But I think it makes sense to try (it). We don’t have anything else.”

CFIA continues surveillance for HPAI in cattle, while sticking with original name for disease – RealAgriculture
The Canada Food Inspection Agency will continue to refer to highly pathogenic avian influenza in cattle as HPAI in cattle, and not refer to it as bovine influenza A virus (BIAV), as suggested by the American Association of Bovine Practitioners earlier this month.
Dr. Martin Appelt, senior director for the Canadian Food Inspection Agency, in the interview below, says at this time Canada will stick with “HPAI in cattle” when referencing the disease that’s been confirmed in dairy cattle in multiple states in the U.S.
The CFIA’s naming policy is consistent with the agency’s U.S. counterparts’, as the U.S. Animal and Plant Health Inspection Service has also said it will continue referring to it as HPAI or H5N1.
Appelt explains how the CFIA is learning from the U.S. experience to-date, and how it is working with veterinarians across Canada to stay vigilant for signs of the disease in dairy and beef cattle.
As of April 19, there has not been a confirmed case of HPAI in cattle in Canada. Appelt says it’s too soon to say if an eventual positive case will significantly restrict animal movement, as is the case with positive poultry cases.
This is a major concern for the cattle industry, as beef cattle especially move north and south across the U.S. border by the thousands. Appelt says that CFIA will address an infection in each species differently in conjunction with how the disease is spread and the threat to neighbouring farms or livestock.
Currently, provincial dairy organizations have advised producers to postpone any non-essential tours of dairy barns, as a precaution, in addition to other biosecurity measures to reduce the risk of cattle contracting HPAI.

Canada has seen a concerning rise in measles cases in the first months of 2024.
By the third week of March, the country had already recorded more than three times the number of cases as all of last year. Canada had just 12 cases of measles in 2023, up from three in 2022.

Cancer Awareness Month
Posted on: Apr 18, 2024
April is Cancer Awareness Month
As we recognize Cancer Awareness Month, we stand together to raise awareness, support those affected, advocate for prevention, early detection, and continued research towards a cure. Cancer is the leading cause of death for Métis women and the second leading cause of death for Métis men. The Otipemisiwak Métis Government of the Métis Nation Within Alberta is working hard to ensure that available supports for Métis Citizens battling cancer are culturally appropriate, comprehensive, and accessible by Métis Albertans at all stages of their cancer journey.
Receiving a cancer diagnosis, whether for yourself or a loved one, can feel overwhelming, leaving you unsure of where to turn for support. In June, our government will be launching the Cancer Supports and Navigation Program which will further support Métis Albertans and their families experiencing cancer by connecting them to OMG-specific cancer resources, external resources, and providing navigation support through the health care system. This program will also include Métis-specific peer support groups for those affected by cancer.
With funding from the Canadian Partnership Against Cancer (CPAC) we have also developed the Métis Cancer Care Course to ensure that Métis Albertans have access to culturally safe and appropriate cancer services. This course is available to cancer care professionals across the country and provides an overview of who Métis people are, our culture, our approaches to health and wellbeing, our experiences with cancer care, and our cancer journey.
Together, we can make a difference in the fight against cancer and ensure equitable access to culturally safe and appropriate care for all Métis Albertans. Please click on the links below to learn more about the supports available for Métis Albertans, including our Compassionate Care: Cancer Transportation program.
I wish you all good health and happiness!
