I believe that it is borderline negligence to diagnose a patient with asthma without training and educating them with an inspirometer.

I'm sorry that I didn't catch this fundamental misunderstanding earlier. The basic problem in asthma, aka reactive airway disease(RAD) and chronic obstructive pulmonary disease(COPD) is the dysfunction in expiration, also known as exhalation, from bronchoconstriction. The impaired airway exchange because they can't empty their lungs means that they retain carbon dioxide while starving for oxygen. That respiratory acidosis causes carbon dioxide narcosis which causes the person to pass out.

Beware of what you read on the net. If you want medical information, check out MedlinePlus first. Get some mileage from your taxes. I haven't caught them passing bogus information. The device is called a spirometer. It is used for gauging forced expiratory volume in one second(FEV₁) and six seconds(FEV₆), the latter being a substitute for forced vital capacity(FVC).

I did perhaps too quick an internet search to remind myself of the name of the device. Other than getting the name of the spirometer wrong, is there some other "fundamental misunderstanding" that you are pointing out?
