A condition that causes prolonged interference with the accession of the blood accompanied by increased `CO_(2)` concentration is called

Options

A. Dyspnea
B. Apnea
C. Asphyxia
D. Eupnea

Answer

To solve the question regarding the condition that causes prolonged interference with the accession of blood accompanied by increased CO₂ concentration, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a condition that leads to prolonged interference with blood oxygenation and is characterized by an increase in carbon dioxide (CO₂) levels in the blood.

2. **Analyzing Option 1 - Dyspnea**:
- Dyspnea refers to shortness of breath or difficulty in breathing. It does not specifically relate to prolonged interference with blood oxygenation or increased CO₂ levels.
- **Conclusion**: This option is incorrect.

3. **Analyzing Option 2 - Apnea**:
- Apnea is defined as a temporary cessation of breathing. While it can lead to increased CO₂ levels, it does not specifically describe a prolonged condition affecting blood oxygenation.
- **Conclusion**: This option is incorrect.

4. **Analyzing Option 3 - Asphyxia**:
- Asphyxia is a condition characterized by a deficiency of oxygen and an excess of carbon dioxide in the body. It occurs when there is inadequate oxygen supply to the tissues, leading to prolonged interference with blood oxygenation.
- **Conclusion**: This option is correct.

5. **Analyzing Option 4 - Eupnea**:
- Eupnea refers to normal, unlabored breathing. It does not relate to any condition of prolonged interference with blood oxygenation or increased CO₂ levels.
- **Conclusion**: This option is incorrect.

### Final Answer:
The correct answer is **Asphyxia** (Option 3), as it is the condition that causes prolonged interference with blood oxygenation and is associated with increased CO₂ concentration.
