Question

Discuss the Disturbances in Oxygen Exchange and Utilization- Obstructive Disorders of the Lungs

Answer 1

COPD Associated with difficulty to Exhale. NORMAL PHYSIOLOGY OF RESPIRATION *Inhaled Oxygen Entering into the Lungs and passed through Bronchial Tubules, then into Bronchioles. *Bronchioles consists of Air sacs known as Alveoli which helps to inflate and deflate. *OXYGEN GO TO THE ALVEOLI AND ENTERED INTO BLOOD STREAM, LEAVE THE CARBON DIOXIDE IN REVERSE DIRECTION. IN COPD PATHOPHYSIOLOGY *Airways are Narrowed or Obstructed by the Inflammation Or the Mucus *More efforts needs to push out the Air *The ability of the alveoli decreased. *The Air sacs of Alveoli become permanently Damaged. *OXYGEN CAN NOT ENTERS INTO BLOOD STREAM *CARBON DIOXIDE DOESN'T LEAVE FROM BLOOD STREAM *LACK OF OXYGEN LEADS TO- Shortness of breath, Wheezing and Fatigue, Increased production of MUCUS In CHRONIC BRONCHITIS *Bronchial tree is Inflamed from irritants *The mucus glands become hypertrophied, Produced thickened Mucus which Obstruct the Airway and trapped air. IN EMPHYSEMA *It affects the Alveolar membrane, Destruction of alveolar Wall and decreased Elastic recoil capacity. *Air is trapped into Alveoli become reduction in gas exchange. IN ASTHMA _ Inflammation of the Mucosal Lining of the Bronchial tree *Bronchospasm occurred due to Narrowing of Air way and Air trapping.
