What Is Lung Capacity?

Simply, lung capacity means the maximum amount of air that your lung is able to hold. Generally, men have a higher lung capacity compared to women. A healthy man’s lung can hold about 1.5 pints of air, whereas a woman’s lung can hold up to 0.6 to 0.8 pints of air.

What Is Lung Capacity

Anyway, most of us don’t use the full capacity of our lungs. According to Jonathan P. Parsons, M.D., professor of internal medicine, “The lungs are over-engineered to accomplish the job that we ask them to do. In healthy people without chronic lung disease, even at maximum exercise intensity, we only use 70 percent of the possible lung capacity.”

To be more specific, lung capacity is a measurement parameter that helps you to calculate the total capacity of your lung volume. There are four ways to measure the capacity of your lung, (VC) – Vital Capacity, (IV) – Inspiratory Capacity, (FRC) – Functional Residual Capacity, and (TLC) – Total Lung Capacity.

  1. Vital Capacity: It’s the volume that can be exhaled after max inspiration. The general value of Vital Capacity is five liters. It’s the overall sum of the IRV, TV, and ERV.
  2. Inspiratory Capacity: IC refers to the amount of air that can be inhaled with max inspiration. The general value of an IC is 3 liters, and it’s the total sum of IRV and TV.
  3. Functional Residual Capacity: FRC means the amount of air remaining in your lung after the end of expiration. The standard value of FRC is three liters, and it’s the total sum of RV and ERV.
  4. Total Lung Capacity: TLC refers to the overall volume of air after the max inspiration. The general value of TLC is six liters, and it’s the total summation of all values.

Why Do You Need To Test Lung Capacity?

If you want to know how well your lung is functioning, you have to do the lung capacity test, which is also known as the pulmonary function test. Lung capacity tests include a variety of tests that help you to check the current condition of your lung.

Why Do You Need To Test Lung Capacity

The most common test that is used for lung capacity is spirometry. Through this test, you can measure the amount of air that your lung can hold. Besides, this test also shows how forcefully an individual can empty air from their lungs.

There is another effective way to test your lung capacity that is Lung Volume Testing. This test is more accurate than spirometry. Through this test, you can measure the amount of air in your lungs. It also includes the air that remains after your normal breath.

Besides, you can do a diffusing lung capacity test that helps you to measure how smoothly oxygen is entering your bloodstream. With an exercise test, you can identify the reasons behind your shortness of breath if you have a breathing problem.

The ultimate goal of doing the above-mentioned lung capacity test is:

  • Identifying the causes behind your breathing problems
  • Monitor and diagnose chronic lung disease such as asthma, COPD, emphysema
  • Determine the effectiveness of your lung treatment
  • To observe the condition of your lung before surgery
  • Find out the exact reason behind your lung problem.

How To Test Lung Capacity At Home?

The significance of testing your lung capacity is enormous if you’ve any respiratory issues like asthma, emphysema, covid-19, etc., or if you’re on oxygen therapy. By doing a lung capacity test, you can examine the capacity and strength of your lung.

It also helps you observe all kinds of changes in your lung over a period of time and assists you in understanding the critical condition of your lung. So that you can take medical help before things get worse.

Now there might be a question that arises in your mind: how to test lung capacity at home without visiting a specialist? If this is what you’re thinking, then there is good news for you. You can easily do the test of your lung capacity from the comfort of your home with an inexpensive lung testing device known as a peak flow meter.

It’s a handheld device capable of determining the strength of your breathing according to the peak expiratory flow. You just need to breathe one end of the device, and the meter of the device will immediately show you the reading on the scale. It shows the results in liters per minute.

Look at the following section to learn how to use this device to test your lung capacity at your home.

  • First, you need to set the meter of the device into zero reading.
  • Now, take a deep breath and maintain your body posture unmoved during the time of testing. It will help you to get more precise results.
  • Keep the mouthpiece of the device properly on the lips and hold it tightly.
  • Breath out with your full effort as forcefully as you can, just for one second.
  • Record the reading seen that you see in the gauge.
  • Reset the peak flow meter to zero reading before you use the device again.

NB: Never calculate the average. During testing, if you encounter a cough or any problem, skip that reading and do the test again. Always keep a record of your peak flow rates and provide them to your physician when needed.
