The disease caused by oxygen starvation due to presence of 750 ppm or more carbon monoxide is called_________

Answer

To solve the question regarding the disease caused by oxygen starvation due to the presence of 750 ppm or more carbon monoxide, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Carbon Monoxide (CO)**: Carbon monoxide is a colorless, odorless gas that can be harmful when inhaled. It is produced from burning fossil fuels and can accumulate in enclosed spaces.

2. **Effects of Carbon Monoxide on the Body**: When inhaled, carbon monoxide binds with hemoglobin in the blood to form carboxyhemoglobin (HbCO). This binding reduces the blood's ability to carry oxygen, leading to oxygen deprivation in the body's tissues.

3. **Concentration Levels**: The question specifies a concentration of 750 parts per million (ppm) or more of carbon monoxide. At this level, the risk of serious health effects increases significantly.

4. **Symptoms of Carbon Monoxide Poisoning**: Symptoms can include headache, dizziness, confusion, weakness, and in severe cases, loss of consciousness or death due to lack of oxygen.

5. **Identifying the Disease**: The condition caused by the lack of oxygen due to carbon monoxide poisoning is known as "carbon monoxide poisoning." However, the specific term for the disease characterized by oxygen starvation is "asphyxiation" or "anoxia."

6. **Final Answer**: The disease caused by oxygen starvation due to the presence of 750 ppm or more carbon monoxide is called **asphyxiation**.
