Rough breathing

Rough breathing, also known as "stridor," is a sound that someone makes when they have trouble breathing. It sounds like a whistle or a squeak and can be heard when someone breathes in or out. It usually happens when there is an obstruction in the airway - this means that something is blocking the air from getting into or out of the lungs.

The airway is like a tube that carries the air from your mouth and nose down into your lungs. When you breathe in air, it goes through your nose or mouth, down your throat, and into your lungs. When you breathe out air, it goes back up the same tube, out of your mouth or nose, and into the air around you.

Sometimes, something can get into the airway and block the air from going through. This can be something like a piece of food that you accidentally breathed in, or it could be something like inflammation in the airway (this means that the airway gets swollen and makes it harder for air to go through). When this happens, someone might make a rough breathing sound because the air can't get through normally.

Another reason someone might make a rough breathing sound is if their vocal cords aren't working correctly. The vocal cords are two little flaps at the top of your windpipe that open and close to create your voice. If they don't work correctly, they can make a rough breathing sound when you breathe in or out.

Overall, if you hear someone making a rough breathing sound, it's important to get them help right away. They might need medical attention to help them breathe more easily and safely.
