What instrument helps in clinical assessment of
pulmonary functions?

Options

A. Sphygmomanometer
B. Stethoscope
C. Spirometer
D. Electrocardiograph

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for an instrument that is specifically used for the clinical assessment of pulmonary functions, which refers to the functions related to the lungs.

2. **Evaluating the Options**: The options provided are:
- Sphygmomanometer
- Stethoscope
- Spirometer
- Electrocardiograph

3. **Analyzing Each Option**:
- **Sphygmomanometer**: This device is used to measure blood pressure, not pulmonary functions. Therefore, it is not the correct answer.
- **Stethoscope**: This instrument is used to listen to heart sounds, lung sounds, and other bodily sounds. While it can provide information about lung health, it does not specifically measure pulmonary functions. Thus, it is not the correct answer.
- **Spirometer**: This is a medical device specifically designed to assess pulmonary functions. It measures various lung volumes and capacities by having the patient inhale and exhale through a tube. This makes it the correct choice for assessing lung function.
- **Electrocardiograph (ECG)**: This device measures the electrical activity of the heart and is not related to pulmonary functions. Therefore, it is not the correct answer.

4. **Conclusion**: After evaluating all the options, the correct instrument that helps in the clinical assessment of pulmonary functions is the **Spirometer**.

**Final Answer**: The instrument that helps in the clinical assessment of pulmonary functions is the **Spirometer**.
