Asthma is an important global health problem affecting nearly 300 million individuals and responsible for 250,000 deaths each year. Asthma is defined by obstruction to the airways, and difficult testing of lung function via spirometry or body plethysmography require complete cooperation by patients in all populations, including the elderly and those who are otherwise ill. Knees even more problematic is that smoking tobacco or respiratory changes in patients with asthma are only largely detectable when it is too late, meaning their respiratory performance has been compromised.
