Unique Discovery: Anus Breathing Technique

Although it may sound strange, but scientists say that humans can now take oxygen through the ‘back passage’ also. Researchers from Japan and America have developed a new technology, through which oxygen can be provided to the body through the anus in case of lung failure.

Antral ventilation: a new scientific language

This process is scientifically called antral ventilation. Recently its first human trials have been successful, and experts consider it the life-saving technology of the future.

inspiration from nature

Although this experiment is new, its inspiration has come from nature. Japanese scientists took inspiration from a fish called ‘loach’, which absorbs oxygen through its digestive system by swallowing air from the surface of the water during times of lack of oxygen. Antral ventilation was discovered on this principle.

Other organisms also have this ability

Researchers also found that some turtles, sea creatures and pigs can also breathe this way. Scientists have named this ‘backdoor breathing’. Preliminary studies were conducted on it in 2021 and it was awarded the Ig Nobel Prize in 2024.

human trial success

The first test was conducted on 27 healthy men led by Professor Takanori Takebe of Osaka University. They were asked to keep a special perfluorocarbon liquid (without oxygen) in the body for 60 minutes. Twenty participants had no problems, while seven experienced mild swelling and discomfort. Importantly, no one had serious side effects.

future prospects

Now scientists are planning to fill this liquid with oxygen so that it can reach the bloodstream directly. Experts believe that this technology can prove to be a boon for those patients whose lungs are not functioning properly or who are not able to get a ventilator.

Preparing for the next phase

Takebe says the next goal is to learn how effective this process is at delivering oxygen to the blood. Scientists believe that if successful, it could prove lifesaving for severe COPD and other lung- patients.
