A spirometer is a device that allows for you to take a deep breath, blow into; then it calculates, stores the data on how fast the patient was blowing, what the volumes are that they're blowing; and it allows then for this information to be fed into a computer. And the current spirometers are very accurate and very easily operated and give us a tremendous amount of information.
