Measuring Lung Capacity
Measuring of Lung Capacity
Introduction
This lab report is over the functions of the lungs and a better understanding of how the respiratory function happens within your body. You will be measuring the amount of air you breathe in and out. This function is called tidal volume, which is about 500 cc of air. Second portion of the testing procedure will be determining the amount of vital capacity or maximum amount your lungs can expel. You will be working in pairs with a lab partner and take turns recording the results. My hypothesis for this procedure will be able to achieve average levels of volume during respiration.
Material and Methods
Materials that are need for this procedure will be; metric ruler, a clamp, and one balloon per person.
Caution though to anyone who has a heart or lung condition that could be aggravated by completing the exercise (Persons, pg 529). The first section of the test will consist of measuring tidal volume. To do this you will exhale normally into the balloon not over exerting yourself. Twist the opening of the balloon so no air will come out and then place the clamp on the twist. Now lay the ruler in front of you and place the widest part of the balloon over top the ruler. Looking over top the balloon make sure one side is on the zero mark and then use a pencil to find the diameter of the balloon and record the results on the chart below. You will complete this process three times for the tidal volume.
Next, you’re going to find the vital capacity of your lungs using the same equipment. This time you will take a deep breath in and exhale into the balloon until with one breath as much as you can. Tie off the end of the balloon again and measure the balloon the same as you did in the first testing procedures. Preform this test three times and record the results on the chart.
Results
Table 1
Measuring Lung Capacity
Diameter (cm) of Balloon Filled With Normal Breath:
Table 1 16 cm
Table 2 17.2 cm
Table 3 17.0 cm
Average 16.6 cm
Volume of air (cc) in balloon filled with normal breath: 2500
Diameter (cm) of Balloon Filled With Deep Breath:
Table 1 19 cm
Table 2 18.5 cm
Table 3 18.5 cm
Average 18.6 cm
Volume of air (cc) in balloon filled with deep breath: 3500 cc
To find the Lung volume in cc from the measurements average cm taken uses the graph in figure 1 to convert from cm to cc.

Discussion and Conclusion The results from the test showed that this person has average lung capacity as predicted in the hypothesis. You have tidal volume when you are resting or not exercising is expected to be lower. Your body does not need or require as much oxygen. When you are in motion or exercising creating vital volume your body needs more oxygen there for increases the volume in the lungs to carry over to the circulatory system.
