Question

Oxygen Toxicity is associated with which of the following

• A. Failure of ventilation of Lungs
• B. Blood Poisoning
• C. The collapse of the alveolar wall
• D. Both B and C

Answer 1

The correct option is A

Failure of ventilation of Lungs

The correct option is option A.

Explanation of correct option:

1. It is harmful to the lungs when exposed to too much supplemental oxygen. This is referred to as oxygen poisoning or toxicity.
2. The air pressure of an alveolar sac rises as the concentration of oxygen rises, failing lung ventilation.
3. Oxygen toxicity, also known as oxygen poisoning, is caused by inhaling excessive amounts of supplemental oxygen.
4. When oxygen is available in higher concentrations than that found in the air, it enters the lungs and damages the alveoli sacs. An excess supply of oxygen to the tissues causes the lungs to fail to ventilate.

Explanation of incorrect options:

Option B:

1. Blood poisoning occurs when chemicals, sometimes caused by microorganisms, are released into the bloodstream to fight an infection, triggering autoimmune reactions such as inflammation.
2. Sepsis is another name for it. Fever, increased heart rate, increased breathing, and confusion are some of the symptoms. Therefore this option is incorrect.

Option C:

1. Hyperoxia is when the body's tissues have too much oxygen. It is caused by breathing too much oxygen at too high a partial pressure.
2. The exposure is hazardous and occurs over an extended period. Long-term exposure causes oxidative damage to the lungs' cell membranes, eventually leading to alveoli damage. This condition causes airway inflammation, alveoli sac inflammation, tracheobronchitis, and breathing failure.

Final Answer: Oxygen Toxicity is associated with Failure of ventilation of the lungs.
