2. •Respiratory Acidosis
-Respiratory acidosis occurs when the lungs can’t remove enough carbon dioxide (CO2). Excess CO2 makes the blood more acidic. This is because the body must balance the ions that control pH.- Normal PH: Normal Pco2 : mm Hg Normal Hco3: 22 – 24 mEq/L

7. Causes :- Causes of respiratory acidosis include:
•Diseases of the airways (such as asthma and chronic obstructive lung disease.PE. pneumonia)
•Diseases of the chest (such as scoliosis)
•Diseases affecting the nerves and muscles that "signal" the lungs to inflate or deflate(multiple sclerosis.kyphoscoliosis.MG)
•Drugs that suppress breathing (including powerful pain medicines, such as narcotics, and "downers," such as benzodiazepines), especially when combined with alcohol
Hypoventilation

8. Clinical features Initial signs of acute respiratory acidosis include:
•headache
•anxiety
•blurred vision
•restlessness
Without treatment, other symptoms may occur. These include:
•sleepiness
•tremors
•delirium

9. Diagnosis :-
Several tools can help doctors diagnose respiratory acidosis.
Blood Gas Measurement (ABC)
This test measures oxygen and CO2 in the blood. High levels of CO2 can indicate acidosis.
Lung Function Tests
Many people with this condition have reduced lung function .especially airflow obstruction
Chest X-Ray
X-rays can help doctors see injuries or other problems likely to cause acidosis like pneumothorax and pneumonia

11. Respiratory Alkalosis
Respiratory alkalosis occurs when carbon dioxide levels drop too low. This causes the pH of the blood to rise and become too alkaline
