Should you listen to exhaled air to check if adult victim is breathing?

Listening for exhaled air is not a reliable method to determine if an adult victim is breathing. Instead, you should look for other signs such as chest rise and fall, and feel for breath on your cheek. The best practice is to check for breathing for no more than 10 seconds using the "look, listen, and feel" method. If there is no breathing or only gasping, call for emergency assistance and begin CPR if trained.
