How well are your lungs working? Let's talk about the Spirometer!

Do you sometimes feel like you're short of breath, or you feel like you're going to have a hard time climbing stairs? Do you have a persistent cough? Or do you make a small noise when you breathe? Today we're going to talk about a small but very important device that our doctors use to find the cause of these things. It's called a spirometer . The name may sound like a big deal, but it's actually very simple.

What is a spirometer? Simply put...

Simply put, a spirometer is a small machine that measures how well your lungs are working. Just like you use a thermometer to check your temperature, a spirometer is used to check the health of your lungs. It basically measures how much air your lungs can take in and how fast you can exhale it. This information can help your doctor determine if you have any lung problems or conditions. So this is not something to be afraid of, it is just a way to learn about your lungs.

How is this spirometer test done?

This test is also very easy to perform. It is not very difficult or painful.

A little preparation before the test...

The doctor will give you some instructions before doing this test.

• You may be asked to stop taking certain medications (especially inhalers) a few hours before the test. Your doctor will tell you exactly what to do.
• If you smoke before the test, you should refrain from doing so .
• Don't come after eating to fill your stomach. Eat normally.
• It's best to wear comfortable, loose clothing . Avoid clothing that constricts the chest.
• It's also a good idea to avoid drinking things like coffee and tea close to the test.

What happens during the test?

Okay, now let's see what happens during the test. 1. First, you'll be asked to sit up straight in a chair. 2. Then, a nurse or technician will put a small clip on your nose. This is to help you breathe through your mouth and not out of your nose. It may feel a little strange, but it won't hurt. 3. Next, you'll be given a small tube to put in your mouth . This is what's connected to the spirometer machine. You'll need to hold the tube tightly in your mouth and seal it with your lips so that no air can escape. 4. Now comes the real work. First, you'll be asked to take a few normal breaths. 5. Then, you'll be asked to take a deep breath in and blow all of it out into the tube as hard as you can.It's like blowing out a bunch of candles on a birthday cake or blowing up a balloon. You need to blow as fast and hard as you can until your lungs are empty. 6. As you blow, the person there will encourage you by saying things like, "Louder! Louder! A little more! Good!" 7. You will be asked to do this two or three times. Check to see if you have done it correctly each time. The test will take about 15 to 30 minutes. This may be a little tiring, and you may feel a little dizzy. But it is not painful.

What does a spirometer measure?

Now you're probably wondering what this will tell you after all this inflation, right? This machine called a spirometer measures several very important things about your lungs. Let's take a look at some of the most important ones.

• FVC (Forced Vital Capacity): This is something like "forced vital capacity". Simply put , this is the total amount of air that comes out of your lungs when you take a deep breath and exhale forcefully. This gives the doctor an idea of ​​how much air your lungs can hold.

• FEV1 (Forced Expiratory Volume in 1 second): This stands for "forced expiratory volume in 1 second". That is, when you blow hard, this is the amount of air that comes out in the first second alone. This is a very important measurement. Because, this is what the doctor can use to determine if there is any obstruction or blockage in your bronchial tubes. If the bronchial tubes are blocked, the amount of air that comes out in the first second is reduced.

• FEV1/FVC ratio: This is the ratio of the FEV1 value mentioned above to the FVC value. This can also give a good idea of ​​the condition of the lungs, especially the airways.

These measurements tell your doctor about the health of your lungs. He or she will decide whether these values ​​are normal, low, or high.

Why do we need this spirometer test?

There may be several reasons for doing this test.

Identify diseases:

This is used to diagnose various lung-related diseases.

• Asthma : This test is often performed if there is a suspicion of asthma.
• COPD ( Chronic Obstructive Pulmonary Disease ): This is a bit of a long name. In Sinhala, it means "chronic obstructive pulmonary disease". It is more common among smokers, or those who are exposed to dust, smoke,A lung disease that is common among people who work with chemicals . This includes conditions like emphysema and chronic bronchitis .
• Cystic Fibrosis : This is a genetic disease that affects the lungs as well as other parts of the body.
• Pulmonary Fibrosis : This is when the lung tissue becomes thick and stiff, making it difficult for the lungs to inflate properly.
• This helps to diagnose many other lung-related diseases.

See how an illness is:

This spirometer test is also performed periodically to check whether the medication given to someone who already has a lung disease is working properly and whether the disease has decreased or increased.

Before an operation:

This test is also important to make sure your lungs are in good health before some major surgeries.

See if your lungs have been damaged by your job:

People who work in certain jobs (for example, those who work in stone quarries, mines, some factories, and paint workers) may inhale dust, gases, and chemicals that are harmful to the lungs. This can also help to determine if their lungs have been damaged.

Do you also have these symptoms?

If you have the following symptoms, your doctor may ask you to take a spirometer test:

• Persistent cough
• Shortness of breath , especially when walking or working
• A feeling of tightness or tightness in the chest
• Wheezing

How do you understand the results of this test?

The doctor compares the values ​​obtained after the test (such as FVC and FEV1) with things like your age, height, gender, and ethnicity . Because there is no single "good" value for everyone. The lung capacity of a small child is different from that of an adult.

"This is like a report card given at school. But don't be afraid of low grades. This will help you find the cause and treat it if necessary."

If your results are "lower" than normal, it could mean you have a problem with your lungs. It could be obstructive (blocked airways, like in asthma or COPD) or restrictive (reduced lung capacity, like in Pulmonary Fibrosis). Your doctor will explain this to you. Sometimes your doctor will give you a medicine called a bronchodilator (an inhaler) to help you breathe.- You may be given a bronchodilator (which makes the airways slightly wider) and asked to do this test again in a few minutes. This is to see if the lung function improves after taking the medicine. This is especially helpful in diagnosing conditions like asthma.

Are there any risks or side effects to this?

This is a very safe test in most cases. However, because of the loud sound, some people may experience:

• Lightheadedness
• Shortness of breath
• Come on, cough.
• You may feel a little tired.

These usually resolve within a short time. However, if you have had a recent heart attack, major eye surgery, major surgery on your chest or abdomen, or uncontrolled high blood pressure, your doctor may think twice about doing this test or postpone it for a few days. So, be sure to tell your doctor about any other medical conditions you have and any medications you are taking.

Who needs this spirometer test most of the time?

As mentioned earlier, this test is especially important for:

• For smokers (and sometimes even for those who have already quit).
• For those with the symptoms mentioned above (cough, shortness of breath, chest tightness, wheezing).
• If anyone in the family (mother, father, siblings) has lung disease (especially asthma, COPD).
• For those who frequently come into contact with dust and chemicals at work.
• Before some surgeries.

Remember these things when you come to the test... (A brief reminder)

• Wear comfortable, loose clothing.
• Take or stop taking medication as the doctor tells you.
• Do not smoke a few hours before the test.
• Don't come after eating a lot.
• Avoid drinking coffee or tea close to the test.
• Don't do strenuous exercise before a test.
• If you have a cold or flu, tell your doctor beforehand. The test may be rescheduled for another day.

So, the final take-home message is:

A spirometer test is not as big or difficult as you might think. It is a very simple, painless test that provides valuable information about your lungs. If your doctor asks you to do this test, don't be afraid or embarrassed about it. Do this for your own good, to learn about the health of your lungs. Sometimes it can detect lung problems before symptoms appear. If so, you can start treatment early and avoid major problems.

Our lungs are like the engine of our lives. It is our responsibility to keep them in good condition. So, take care of your breathing and don't hesitate to get this test done if necessary!
