Can someone clearly tell the difference between shallow breathing and hyperventilation-?
You can breathe as fast and shallow as you want and that’s just what it is called “fast and shallow”. Hyperventilation does not describe a breathing pattern, it describes what is occurring with gas exchange in the lungs. “Ventilation” refers to carbon dioxide diffusion into and out of the lungs. If you are hyperventilating, this means that you are blowing off too much CO2. If on the other hand you are hypoventilating, then you are retaining too much CO2. Hyperventilation can be caused by many things including pain, fear, anxiety, and stimulating drugs.
