Explain the pathologies of Obstructive and Restrictive pulmonary diseases. Include in your discussion why these pathologies result in the signs and symptoms of each disease class. Also name at least two conditions associated with each major pulmonary disease class (i.e. Chronic Bronchitis-Obstructive) (3 pt).
- Obstructive pulmonary diseases have shortness of breath due to difficulty exhaling all the air from the lungs. Because of damage to the lungs or narrowing of the airways inside the lungs, exhaled air comes out more slowly than normal. At the end of a full exhalation, an abnormally high amount of air may still linger in the lungs.
* Two conditions associated with obstructive pulmonary diseases are:
a) Asthma
b) COPD which include the emphysema and chronic bronchitis.
- Restrictive pulmonary diseases cannot fully fill their lungs with air. The lungs are restricted from fully expanding.
* Two conditions associated with restrictive pulmonary diseases are:
a) Pneumonia:
b) Scoliosis
7. Describe the physiology of the FEV1/FVC ratio and what is the clinical significance of an abnormal ratio? DO NOT provide the definition of the ratio (3 pt). - The significance is that it describes the effectiveness of how well an individuals lungs can turn over its total volume in 1 second. - The clinical significance of an abnormal ratio is
8. What values have been affected by simulated airway restriction?
9. Are these values the
