Respiratory disorders include:
- chronic bronchitis
- pulmonary fibrosis\pneumoconiosis
- cystic fibrosis
- chronic pulmonary hypertension
These disorders can cause shortness of breath, chest pain, coughing, wheezing, sputum production, coughing resulting in production of blood and tachypnea.
The respiratory disorders must result in significant impairment of one’s breathing as measured on pulmonary function tests, such as spirometry (ventilation of the lungs), DLCO tests (gas diffusion in the lungs) ABG tests (partial pressure of oxygen, PaO2, and carbon dioxide, PaCO2, in the arterial blood), and pulse oximetry (oxygen saturation, SpO2, of peripheral blood hemoglobin).
