A simple spirometer can be made using a large plastic bottle, a straw, and a water source. Cut the bottom off the bottle and fill it partially with water, then insert the straw into the bottle without letting it touch the water. As you exhale into the straw, the air will displace the water, allowing you to measure the volume of air expelled. Ensure the setup is airtight to get accurate readings.
A spirometer can be used to monitor a person's breathing rate and the volume of air inhaled and exhaled. For persons suffering of lung-disease or asthma, this can make a spirometer a valuable monitoring tool in regards of their specific illnesses.

The least count of a spirometer typically ranges from 1 ml to 10 ml, depending on the model and precision of the device. This value represents the smallest volume change that can be accurately measured by the spirometer.

Vital capacity is measured using a spirometer. The person takes a deep breath in and then exhales as forcefully and completely as possible into the spirometer. The spirometer records the volume of air exhaled, which is used to calculate the vital capacity.

Lung volume can be measured using a simple spirometer test. This test involves taking a deep breath and blowing into a tube connected to the spirometer, which measures the volume of air exhaled. The results can provide information on lung function and capacity.
One example is the spirometer.
