Wheezing does not necessarily mean you are having an asthma attack. However, it can indicate inflammation and / or narrowing of the airway. Both of which are dangerous to someone with asthma and can increase the risk of an asthma attack. Yes, wheezing can be noticed though whistling or laboured breathing. However, a wheezo can detect signs of wheeze on a macroscopic scale; meaning you can treat the issue before you are clearly wheezing and at heightened risk of an asthma attack.

In children, wheezing is critical to detect as the child may not be able to communicate any issues. In adults, this is equally important as you can detect microscopic signs of wheeze before you notice whistling or laboured breathing. Both of give provide information to treat a small issue before it becomes a problem.
