Lung Function

The lungs, located in the chest alongside the heart, trachea and esophagus, are responsible for general respiration. Lung function converts air into fresh oxygen that can be carried throughout the body. Each day, approximately 9,000 liters of air is breathed in to meet 8 - 10,000 liters of blood pumping through the circulatory system. Due to the lungs advanced filtering mechanism, they are able to combat general toxins that may enter the bloodstream to ensure the oxygen combining with blood is pure before it is pumped throughout the body.

What is lung disease?

Lung disease is the number three killer in the United States, responsible for one in six deaths. According to the American Lung Association, more than 35 million Americans are living with chronic lung disease such as asthma and chronic obstructive pulmonary disease (COPD), otherwise known as emphysema and chronic bronchitis. Other lung diseases include:

  • Cystic fibrosis
  • Sarcoidosis with advanced fibrosis
  • Pulmonary hypertension
  • Damage to lung arteries caused by an untreated congenital heart defect (Eisenmenger syndrome)
