Expand-A-Lung (Pack of 2)| Breathing Fitness Exerciser Device | Expiratory Inspiratory Muscle Oxygen Trainer | Increase Lung Capacity, Improves Sleep, Fitness & Respiratory Therapy | Since 2004
The flow of air in and out of the alveoli is called ventilation and has two
stages: inspiration (or inhalation) and expiration (or exhalation). To
accomplish this, the whole thorax moves and changes size, due to the action of
two sets of muscles: the intercostal muscles and the diaphragm. These are the
muscles that are strengthened by using the Expand-A-Lung Breathing Resistance
Exerciser. In essence, you inhale more oxygen, and you exhale more carbon
dioxide. The result is a substantial improvement in shortness of breath and
endurance through better breathing. All is done naturally, with the help of
the Expand-A-Lung Breathing Resistance Exerciser. 5 year unlimited warranty
for parts and labor.
