How to Check If Your Lungs Are Healthy at Home: A Guide for Seniors and People with COPD, Asthma, and Other Respiratory Diseases

Having healthy lungs is essential to living a full and active life. Unfortunately, many people suffer from chronic respiratory conditions such as COPD or asthma that can cause shortness of breath and other problems. It's important to know how to check if your lungs are healthy at home so you can be aware of any changes in your health before they become serious issues.

With the right tools, you can easily perform tests like checking your breathing rate, performing peak flow tests, and taking oxygen saturation readings all without having to visit a doctor’s office. In this blog post we'll discuss these topics in more detail so you can check if your lungs are healthy at home quickly and accurately.

Understand the Symptoms of Poor Lung Health

Shortness of breath is one of the most common symptoms of poor lung health. It can be caused by a variety of conditions, including asthma, COPD (chronic obstructive pulmonary disease), and other respiratory diseases.

Shortness of breath

Shortness of breath can range from mild to severe and may be accompanied by chest tightness or wheezing. People with shortness of breath often find it difficult to do everyday activities such as walking up stairs or carrying groceries.


Coughing is another symptom that can indicate poor lung health. Coughs are usually caused by an infection in the lungs, but they can also be due to allergies or environmental irritants like smoke or dust particles. Coughs may produce mucus that ranges from clear to yellowish-green in color and could have a foul odor if there’s an infection present.


Wheezing is a whistling sound made when breathing out air through narrowed airways in the lungs due to inflammation or swelling from an illness like asthma or COPD. Wheezing typically occurs during exhaling and may worsen with activity such as exercise or climbing stairs.

Chest tightness

Chest tightness is another sign that something might not be right with your lungs; it’s often associated with difficulty breathing and/or pain while inhaling deeply which could signal pneumonia, bronchitis, heart failure or pleurisy (inflammation around the lungs), depending on what else you are experiencing at the same time such as fever.

Chest tightness should always be checked out by your doctor for proper diagnosis so treatment options can begin immediately if needed.

Finally, seek professional help if any combination of these symptoms persists over several days even after trying home remedies like drinking lots of fluids and taking over-the-counter medications for cold & flu relief. This will ensure you get properly diagnosed so you know how best to treat whatever condition you might have before it worsens further, potentially leading to more serious complications down the road.

It is important to understand the signs and symptoms of poor lung health, so that you can take steps to protect your lungs and maintain good respiratory health. Next, let's look at how you can check your breathing rate at home.

Check Your Breathing Rate

Measuring your breathing rate is an important part of understanding your lung health. Your breathing rate, or respiratory rate, is the number of breaths you take in a minute.

To measure it accurately, sit comfortably and place one hand on your chest and the other on your stomach. Count how many times you breathe in for 15 seconds and then multiply that number by four to get your total breaths per minute (BPM).

A normal resting BPM for adults ranges from 12-20 breaths per minute. If you find yourself taking significantly more breaths than this per minute when at rest, it could be a sign of poor lung health or another underlying medical condition such as asthma or COPD.

It’s important to speak with a doctor if you are experiencing any changes in breathing patterns so they can help diagnose any potential issues early on before they become serious problems.

In addition to measuring your resting BPM, it’s also beneficial to monitor how much effort it takes for you to inhale and exhale air throughout the day. This will give you an indication of how well oxygen is being exchanged between your lungs and bloodstream which can help determine if supplemental oxygen may be necessary due to low blood oxygen levels caused by certain diseases like COPD or pulmonary fibrosis.

It is also helpful to pay attention to any shortness of breath during physical activity such as walking up stairs or running errands around town, since this can indicate whether additional support may be needed while engaging in daily activities due to weakened lung capacity caused by disease progression over time.

Finally, keep track of any coughing fits that last longer than usual since these could be signs that something else is going on within the body such as infection or inflammation which should always be discussed with a physician right away if experienced frequently enough over time.

By monitoring your breathing rate, you can get a better understanding of how healthy your lungs are. Now let's move on to performing a peak flow test to further assess the condition of your lungs.

Perform a Peak Flow Test

A peak flow test is a simple and effective way to measure how well your lungs are functioning. It can be done at home with the help of a peak flow meter, which measures the amount of air you can exhale in one breath. The results from this test can help you and your doctor determine if your breathing is normal or if there may be an underlying problem that needs to be addressed.

To perform a peak flow test, start by standing up straight and taking a deep breath in through your nose while closing off both nostrils with your fingers. Then, open one nostril and blow out as hard as you can into the mouthpiece of the peak flow meter for about three seconds until all the air has been expelled from your lungs. Make sure to keep track of how much air was expelled during each attempt so that you have accurate readings for comparison later on.

The next step is to repeat this process two more times using different levels of force each time; once at full capacity (maximum effort) and then again at half capacity (medium effort).

Once all three attempts have been completed, take note of the highest reading achieved during any one attempt – this will give you an indication as to what constitutes a normal level for yourself when it comes to lung function tests like these.

It’s important not to compare yourself against others when performing these tests since everyone’s body works differently; instead focus on tracking changes over time so that any potential issues can be identified early on before they become serious health concerns down the line.

If after several attempts there appears no improvement or even worse – deterioration – it might be wise to seek professional medical advice right away just in case something else could potentially be causing problems with breathing such as COPD or asthma-related conditions etc.

Performing a peak flow test is an easy and effective way to measure your lung health at home. By understanding your peak flow readings, you can gain insight into how well your lungs are functioning and take the next step towards better respiratory health by taking an oxygen saturation test.

Take an Oxygen Saturation Test

Taking an oxygen saturation test is a simple way to measure the amount of oxygen in your blood. A pulse oximeter, which can be purchased at most pharmacies or online, is used to take this test. The device clips onto your finger and uses light sensors to measure the amount of oxygen in your bloodstream.

To begin the test, make sure that you are sitting comfortably with both feet flat on the floor and place your index finger into the clip of the pulse oximeter. It should fit snugly but not too tight as it may affect accuracy. Once clipped on, wait for about 30 seconds until you get a reading from the device.

A normal oxygen saturation level ranges between 95-100%. If your reading falls below 92%, it indicates that there is not enough oxygen circulating through your body and could be a sign of respiratory distress or other health issues such as COPD or asthma. In these cases, it’s important to seek medical attention right away if symptoms persist after taking an oxygen saturation test at home.

It’s also important to note that certain factors can affect how accurate an oxygen saturation test will be including age, activity levels and altitude changes due to air travel or living in high elevation areas like mountainside towns.

Additionally, some medications can interfere with readings so always consult with a doctor before taking any tests at home if you are currently taking medication for any health conditions related to lung function or breathing problems such as COPD or asthma.

An oxygen saturation test is a simple and quick way to measure your body's ability to absorb oxygen, so it's important to take one regularly. If you find that your results are lower than expected, it may be time to seek professional help.

Seek Professional Help

If you are experiencing any concerning symptoms related to your lung health, such as shortness of breath, chest pain or tightness, wheezing, coughing up blood or mucus that is different from normal, fatigue and weakness or a change in the color of your skin due to low oxygen levels it is important to seek professional medical help. Your doctor can perform tests and provide treatments tailored specifically for you

Your doctor may order an X-ray to check for signs of infection in your lungs. A CT scan may also be used if there is suspicion of cancer or other abnormalities. Your doctor will likely ask about your family history and lifestyle habits like smoking which could affect your lung health.

They might also recommend pulmonary function tests (PFTs) which measure how well air moves through the lungs by measuring the amount of air inhaled and exhaled during a test period.

Your doctor may prescribe medications such as bronchodilators which open up narrowed airways caused by asthma attacks; corticosteroids to reduce inflammation; antibiotics if an infection is present; supplemental oxygen therapy with portable oxygen concentrators, should it be needed; and/or immunotherapy injections depending on the condition diagnosed after evaluating all test results.

It is important to keep track of any changes in breathing rate or peak flow readings over time so that these numbers can be shared with your healthcare provider at each visit for evaluation purposes.

If you have COPD or another chronic respiratory illness, regular visits with a pulmonologist are recommended even when no symptoms are present; this allows potential issues to be addressed quickly before they become more serious problems requiring hospitalization later on.
