Heated humidified high-flow therapy

Heated humidified high-flow therapy is like giving your nose a warm hug with a misty bath.

Sometimes when people have trouble breathing or their nose is stuffy or dry, they may need some extra help to feel better. Heated humidified high-flow therapy is a way to help them breathe better and feel more comfortable.

Here's how it works. Oxygen and air are mixed together and warmed up. Then, water is added to the mix to create a misty bath of warm air. This misty air flows through a tube that is connected to a mask or nasal cannula that the person wears on their nose.

When the person breathes in, the warm misty air helps to open up their airways and moisten their nose and throat. This can be really helpful for people who are having trouble breathing, especially if they have a cold or the flu.

The high-flow part of heated humidified high-flow therapy means that the misty air is flowing really fast through the tube and into the person's nose. This can be really helpful for people who need a lot of oxygen or have trouble breathing.

Overall, heated humidified high-flow therapy is a way to help people breathe better and feel more comfortable when they're having trouble breathing. It's like giving your nose a warm hug with a misty bath!
