{'sphygmomanometer': [1, 0, 0, 0], 'barometer': [0, 0, 0, 2], 'haemocytometer': [1, 0, 0, 0], 'spirometer': [1, 0, 0, 0], 'blood pressure': [5, 0, 0, 0], 'instrument': [4, 0, 2, 5]}

The correct answer is option 3, sphygmomanometer.

1. Barometer: A barometer is a device used to measure atmospheric pressure, not blood pressure. It is commonly used in weather forecasting.

2. Spirometer: A spirometer is a device used to measure lung capacity and airflow, not blood pressure. It is commonly used in respiratory function tests.

3. Sphygmomanometer: This is the correct answer. A sphygmomanometer is an instrument used to measure blood pressure. It consists of an inflatable cuff that is wrapped around the arm and a pressure gauge that measures the pressure in the cuff.

4. Haemocytometer: A haemocytometer is a device used to count and measure the concentration of blood cells, not to measure blood pressure.

Therefore, the correct instrument for measuring blood pressure is a sphygmomanometer.
