Which instrumental helps in clinical assessment of Pulmonary Volumes?

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which instrument is used for the clinical assessment of pulmonary volumes. Pulmonary volumes refer to the amount of air in the lungs at different phases of the respiratory cycle.

2. **Reviewing the Options**:
- **Option 1: Sphygmomanometer**: This instrument is used to measure blood pressure, not pulmonary volumes. Therefore, this option is incorrect.
- **Option 2: Stethoscope**: A stethoscope is used to listen to sounds within the body, such as heartbeats and lung sounds, but it does not measure the volume of air in the lungs. Hence, this option is also incorrect.
- **Option 3: Spirometer**: A spirometer is specifically designed to measure the volume of air inhaled and exhaled by the lungs. It assesses lung function and is directly related to pulmonary volumes. This option is correct.
- **Option 4: Electrocardiograph**: An electrocardiograph records the electrical activity of the heart, not the lung volumes. Therefore, this option is incorrect.

3. **Conclusion**: After evaluating all the options, the instrument that helps in the clinical assessment of pulmonary volumes is the **spirometer**.

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