Which of the following is the life saving mixture for an asthma patient

Options

A. Mixture of helium and oxygen
B. mixture of neon and oxygen
C. mixture of xenon and nitrogen
D. mixture of argon and oxygen

Explanation

To determine the life-saving mixture for an asthma patient, we need to analyze the options provided and understand the properties of the gases involved.

### Step-by-Step Solution:

1. **Understanding Asthma**: Asthma is a respiratory condition characterized by difficulty in breathing due to narrowed airways. Patients often require a mixture of gases that can help in improving oxygen delivery and reduce airway resistance.

2. **Analyzing the Options**:
- **Helium Oxygen**: This mixture consists of helium and oxygen. Helium is a lighter gas that can help in reducing the density of the gas mixture, allowing it to flow more easily through constricted airways.
- **Neon Oxygen**: Neon is also a noble gas, but it does not have the same beneficial properties for breathing as helium.
- **Xenon Nitrogen**: Xenon is another noble gas, but nitrogen can be harmful in high concentrations, especially for patients with respiratory issues.
- **Argon Oxygen**: Argon is also a noble gas, but like neon, it does not provide the same advantages as helium.

3. **Properties of Helium**: Helium is less soluble in blood compared to other gases, which means it does not dissolve as readily. This property allows for quicker delivery of oxygen to the lungs and is beneficial for patients with respiratory conditions.

4. **Conclusion**: Based on the analysis, the best option for a life-saving mixture for an asthma patient is **Helium Oxygen**. This mixture helps in improving airflow and oxygen delivery, making it suitable for asthma management.

### Final Answer:
The life-saving mixture for an asthma patient is **Helium Oxygen**.
