Chronic Obstructive Pulmonary Disease

COPD is an abbreviation for chronic obstructive pulmonary disease. COPD is the overall term for a group of long-standing (chronic) conditions that result in obstruction of the lung's airways. COPD often slowly and silently steals the ability to breathe normally. "If you're inactive, you may not even notice how much lung function you've already lost," explains Winder. "But when people with COPD exert themselves more than usual, they often find they are surprisingly short of breath."

The term COPD usually refers to two disorders:

  • Chronic bronchitis&
  • Emphysema

Most people with COPD have a combination of the disorders. Smoking is the main cause of COPD. There is as much as a twenty-five percent chance of developing COPD if you smoke cigarettes, cigars or a pipe.

Vmax Autobox

The Vmax Autobox's sensitive, pressurized cabin combines the total flow/volume loop measurement with sensitive measurement of cabin volume displaced by the patient's chest movement. Another means of measuring total lung capacity is through nitrogen washout. Together, the measurements provide a true assessment of absolute lung volume while providing an excellent index of patient breathing efforts and potential reasons for airflow limitations.
