Pulmonary Function Tests or PFTs are a set of tests that are used to determine, measure or observe the functioning of the lungs. The most common pulmonary function tests used are spirometry, gas diffusion, and lung plethysmography. 

Highlights of pulmonary function tests

A spirometry test is used to measure the amount of air inhaled and exhaled. It also measures the amount of time taken to complete a respiration cycle.
A lung plethysmography measures the amount of air in the lungs after the patient has taken a deep breath. It also measures the amount of air that remains in the lungs after the patient has exhaled as much air as possible.
What does a Pulmonary Function Test measure?
Pulmonary function tests would not only check how well the person is breathing but also how effectively the lungs are able to conduct oxygen to the rest of the body. In addition to air flow, these tests would measure the size and volume of the lung and lung diffusion.

These tests can also be used to measure

Total Lung Capacity   the amount of air present in the lungs after breathing in deeply
Forced Vital Capacity   the amount of air that can be exhaled after breathing in deeply
Minute Volume   the amount of air exhaled per minute
Vital Capacity   the total volume of air that can be breathed out after inhaling as much as possible
Tidal Volume   the amount of air inhaled or exhaled when breathing normally
Maximum voluntary ventilation   the amount of air that can be inhaled and exhaled in one minute
Functional Residual Capacity   the amount of air that remains in the lungs when breathing normally
Forced Expiratory Flow   the flow or volume of air during an exhalation
Peak Expiratory Flow Rate   the rate at which a person can exhale
When are Pulmonary Function Tests recommended?
A physician might recommend a patient undergo a PFT as part of a routine physical check-up. This test would be advised if the patient is experiencing any symptoms associated with lung problems or disorders such as asthma, respiratory infections, chronic obstructive pulmonary disease, COPD. A doctor would also use these tests to monitor and check whether a certain treatment prescribed for a lung disease or condition is working effectively.

Pulmonary function tests are safe as they are non-invasive but it is important to follow the instructions of the doctor or technician before, after and during the test. It is important to make your doctor aware of any surgeries, respiratory infections, chest pains or heart attacks that you might have experienced before the test. If you are taking any medications you might need to follow the advice of the doctor as to whether you can take them before the test.

Your doctor would also advice you on how to prepare for the test such as not eating a large meal, avoiding caffeine and wearing loose-fitting clothes. If you have any doubts, concerns or queries discuss them with your doctor.

Pulmonary Function Tests - Why Is It Required?

Asthma is a chronic lung condition wherein the air passage gets blocked or constricted due to the production of extra mucus. It is an age old condition which has been creating problems for people since a long time. Despite the seriousness of the condition, there are various myths people tend to believe about asthma.

Here are a few myths about asthma and the usage of inhalers:

Regular Usage of Inhalers is Addictive: This is a total myth. Using inhalers is not at all addictive, it is a necessity. Just because you use your inhaler regularly does not mean you are addicted to it.  Just like brushing your teeth every day isn't an addiction, taking your daily medicine from an inhaler isn't an addiction as well. Using an inhaler will just help you with your asthma condition.
Oral Medicine Gets Better Results than Inhalers: Absolutely not. In fact, it is proven that inhalers give better results than oral medications. Oral medication takes longer to act during a sudden asthma attack while inhalers deliver the drug directly to the lungs.
Inhalers Are Meant For Severe Asthma Cases: Well, this again is not true. Inhalers are used for treating asthma. Period. Asthma is a condition where your lungs inflame which is best cured with steroids, and the easiest way to have steroids administered to you is through the inhalation method. When you use the inhalers, the steroids are delivered directly to your lungs. They also have a minimum number of side effects when administered through inhalers.
Asthma is Curable: You might tend to think that asthma can be cured with the help of proper medications. You might think that asthma is not a constant condition. But it is not what you think. The symptoms of asthma might not be present all the time but that doesn't mean you do not have asthma. Asthma is a long-term condition where the airways swell up causing you to suffer from breathlessness. If you suddenly stop taking your daily medicines because the symptoms have not surfaced, then it will take you a long time before you will be able to totally recover from the next attack you suffer from.
If you have asthma, remember to take your medicines daily and timely. 

Debunking Asthma Myths

Asthma is a common disease, characterized by the inflammation of the airways. These airways are responsible for the passage of air and therefore their inflammation causes shortness of breath and extreme discomfort. Though different branches of medicines have tried in their own ways to deal with this problem, ayurveda with its emphasis on natural remedies has emerged as a clear favorite. According to ayurveda, it is the stomach that is the source of all chronic diseases. The science believes that as impurities accumulate in our system, diseases like asthma come to the fore. The different ways by which ayurveda treats asthma are:

1. Maintaining a proper diet: since stomach is identified as the source of most diseases, any attempt to treat them should begin from the stomach itself. Ayurveda believes that those foods, which are easy to digest, inevitably helps in relieving you from the bouts of asthma. The concept that operates behind this is that easily digestible food provides nutrients, which are further absorbed by the tissues. This helps in rebuilding the strong strength as well as keeps the stomach in a sound condition.

2. Herbal oil massage: a daily massage with herbal oil has always proved to have an extremely soothing and a calming effect on your system. Ideally the massage should be performed before taking a bath as it increases the blood circulation and pacify the nervous system.

3. Exercise: ayurveda is perhaps the only branch of medicine that gives equal priority to medications as well as exercises. It is believed that stretching and those exercises that facilitate flexibility can markedly reduce bouts of asthma.




Role of Ayurveda in Treating Asthma 

Asthma is a distressing condition during which people find it difficult to breathe as the bronchi or tubes carrying air to lungs swell up. This happens when mucus inside bronchi comes into contact with an allergen like a pollutant or dirt causing symptoms like wheezing, coughing, more mucus production and difficulty breathing. There is no cure for asthma. As of now, it can only be managed. But managing asthma becomes really difficult during low air quality days, especially during winters when it s cold and dry.

The most common air pollutants are gases like sulphur dioxide, nitrogen dioxide, vehicle smoke, and suspended particles. Each one of them can trigger an asthma attack by itself because of its deleterious effect on the lungs. The smaller the particulate matter is, the more dangerous it becomes as these particles get lodged in the air sacs inside lungs, causing not just asthma from worsening but also fatal diseases like lung cancer.

So, most asthma patients suffer from frequent attacks due to air pollution. How can these attacks be prevented? Here are some tips:

According to research, asthma can be managed by making modifications in everyday life. On high air pollution days due to ozone, for example, asthmatics tend to experience more lung inflammation. If you are an asthmatic, you should reduce time spent outdoors, especially doing strenuous activity in the mornings and evenings. Keeping medications on hand and using those at the very start of an asthma attack also helps. There should always be a plan in place to lessen the chance of an asthma attack on poor air quality days starting from a rescue inhaler to preventive medication if your doctor feels you need it.
Stay hydrated and breathe through the nose. Dehydration is dangerous for asthmatics especially when air quality is bad. In this case, lungs can become badly affected because they need right temperature and levels of water to work properly. It s crucial to breathe through the nose only and not the mouth as the air breathed in from the mouth can be very cold and dry and can cause even more inflammation of the lungs.
Know your asthma triggers and change lifestyle. Avoiding your triggers is key to managing asthma. If traffic fumes are a trigger, it s best to change the route you take to work to manage your asthma. If you don t know your triggers look back at your last asthma attack and remember what you were doing. Did you pet your dog? Write a diary and discuss with your doctor on how to avoid your triggers. Use a face mask when outdoors to limit exposure to allergens. 
Track your asthma to recognise early signs of asthma. If you know that it s getting worse, you should have a fool-proof plan in place.

Air Pollution - Tips to Prevent Asthma From Worsening!

If you are experiencing a whizzing sound while you breathe or having difficulty in breathing, you are suffering from asthma. It is a medical condition characterized by paroxysmal wheezing respiration dyspnoea. There is no definite way to prevent asthma, but by following a step-by-step daily plan, you can prevent asthma attacks or keep them in check. Here are some important measures to follow to prevent asthma:

You need to strictly follow your asthma action plan. The plan should be laid down after a detailed discussion with your doctor or healthcare team. All the medicines you require to prevent the asthma attacks will be written down for you.
You should get vaccinated for pneumonia and influenza. This will prevent these conditions from triggering asthma attacks or flare-ups.
You need to identify the asthma triggers and stay away from them. Several outdoors irritants and allergens from pollen to cold air can trigger asthma attacks.
You have to monitor your breathing. By recognising the warning signs of an attack like wheezing, slight coughing or shortness of breath, you can prevent an asthma attack. You need to measure and record your peak airflow regularly using a home peak flow meter.
By acting quickly, you can identify a fatal attack and prevent it from occurring. When the peak flow measurement decreases, you need to take your medicines immediately and abstain from any activity which may have triggered the attack.
You need to keep taking your prescribed medicines, even if your asthma symptoms have improved. You should not change your medication schedule without consulting a doctor. It is recommended that you to bring along the medicines you take at your doctor s appointment as he will be able to tell whether you are taking them right.
If you use your quick relief inhaler a lot, the asthma is not under control. You need to visit your doctor as soon as possible and he/she will make some modifications to your treatment.
For prevention of asthma, you should use allergy proof pillow covers and mattresses. You must wash your bedding every week in hot water to eliminate dust mites. You may use a dehumidifier for reducing excess moisture to prevent mold.
Do not allow your pets in the bedroom and on the furniture. Pet dander is a common trigger of asthma and it cannot be avoided by people who own pets.
You can also fit an air filtration system in your home. It will help in the elimination of asthma triggers such as pollen, dust mites and other allergens.
Many doctors suggest immunotherapy for asthma prevention in the form of allergy shots. Immunotherapy aims at altering a person s immune response by making it less sensitive to asthma triggers.
