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?

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.

Asthma - 10 Ways to Keep it Under Control

Is your child getting exhausted after a bout of cough? Does he or she suffer from constant wheezing and tightness of the chest? Does your child feel drained out after climbing a flight of stairs? Do you know a child who always seems to run out of breath and cannot participate in school sports tournaments or play outside for a long time? The child could be suffering from asthma, which is a serious breathing problem. Most children are affected by asthma. Staying in a polluted city just makes the condition worse.

Asthma - Know the disease

Asthma is a condition that causes inflammation of the airways, known as trachea and bronchioles.
The muscles around the airways constrict and prevent the smooth flow of air.
The lining of the bronchioles swell and block the airways.
Asthma is mostly triggered by an allergic reaction.
There is a difficulty in breathing out. Exhalation of air is often accompanied by a wheezing, that is, a whistling sound.
There is a constant shortness of breath, feeling out of breath and gasping for air.
There is an uncomfortable tightness in the chest, the feeling of not breathing in enough air.
Coughing bouts in the middle of the night, that leave the child feeling exhausted and completely out of breath.
Causes of Asthma 

Asthma is mostly triggered by asthma allergens. These allergens are mostly pollens and animal fur.

Exposure to pollution, such as dust and smoke
Heredity
Obesity
History of heartburn, GERD and acid reflux
Inflammation of sinus and airways
History of bronchial disorders and pneumonia
Viral infections
Chronic rhinitis
Low immunity causing constant cold and blockage of nose
Treatments of asthma

A nebulizer that turns asthma medicine into a mist can then be inhaled easily
An inhaler can be used to take in inhaled steroids into the lungs or a bronchodilutor
Try and avoid asthma triggers and allergens as much as possible
Avoid physical stress and heat
Get sufficient rest of about 7-8 hours every day

Troubled Breathing - Can It Be a Sign of Asthma?

Asthma is an inflammatory disease, which affects the airways of your lungs (respiratory tract that pumps oxygen into the lungs). It is long term in nature. It is characterized by shortness of breath, coughing and wheezing. It occurs a few times a day or a few times a week depending on the person it affects. Sometimes it worsens during the night.

What triggers Asthma?

Airborne particles such as dust mites, mould spores, pollen and cockroach waste.
Infections in the respiratory system such as a common cold.
Cold air can also trigger asthma.
Physical or outdoor activities which make you pant such as running, skipping, jogging and jumping can cause shortness of breath, thus triggering asthma.
Pollutants and irritants in air such as smoke.
Some medications can also trigger asthma.
Stress and nervous attacks (panic attacks) also trigger asthma.
How to manage asthma better by changing your lifestyle:

Try to avoid keeping animals in your houses such as dogs, cats and rabbits. Many times animal fur, waste, urine and saliva contains particles which can cause allergic reactions and make you cough uncontrollably. This, in turn, triggers asthma attacks. If you have pets try keeping them away from your bedroom.
Dust mites also cause allergies which trigger asthma. So wash your carpets, rugs, bed-linen and pillowcases in hot water.
Bugs and insects such as cockroaches are not only unhygienic but can also trigger asthma. Cockroach droppings near your bed, kitchen and food are dangerous and you should call an exterminator to get rid of these bugs.
Sometimes, the heavy fragrance also aggravates your respiratory tract and triggers shortness of breath. Avoid using heavy perfumes, deodorants and room fresheners.
Pollution also triggers asthma. Dust particles come out from the vehicles and mix with the air. If this air is inhaled, it might trigger uncontrollable asthma. So try to cover your mouth with a cloth when you step out of your house.
Asthma can be very severe and can bring many hurdles in your day to day activities. Changing your lifestyle and certain habits can reduce asthma to a great extent.

Lifestyle Changes to Manage Asthma Better

Symptoms of Acute Bronchitis

Most of India’s urban populace is highly prone to respiratory infections and problems due to the dangerously high air pollution levels in all major cities across the country. Air we breathe in travels through the bronchial tube to reach our lungs. Problem begins when these tubes get inflamed and mucus builds up. It leads to coughing and shortness of breath which is known as bronchitis. It is very important to identify the symptoms in the beginning and get yourself treated by a doctor immediately. 

Look out for these symptoms of acute bronchitis.

1. Prolonged Cough - If your coughing goes beyond ten days, it could be bronchitis. If you have been coughing so long, check if the mucus is coloured too.

2. Shortness Of Breath - If you are facing shortness of breath despite not being asthmatic, you should see a doctor.

3. Chest Pain - Chest pain and chest tightness could be a symptom of acute bronchitis as breathing troubles might cause problems in such areas.

4. Sore Throat - Sore throat with persistent coughing is also a symptom for acute bronchitis.

5. Flu Like Symptoms - Most children show very different symptoms of bronchitis. They might show flu like signs of runny nose, sore throat, back or muscle pain and chills.

6. Weight Loss - You might also experience unexplained weight loss.

7. Barking Cough - Deep, barking cough is a sure shot symptom of something serious and you need a consult a specialist immediately.

Did You Know: Every 7th Urban Indian Is Prone To  Bronchitis

Asthma is a chronic respiratory disorder. In asthma, the airways of the lungs get inflamed. Due to this inflammation, there is swelling inside the airways. This also causes excess production of mucous. The combined effect of swelling and mucus production is that the passage of air gets obstructed. This makes breathing difficult. A whistling sound or wheezing is often heard in such patients. Often the patient gets cough due to this obstruction of the airways. This cough is a reflex of the body to get rid of the excess mucous in the airways. A sense of tightness or heaviness is felt in the chest. One cannot expand the chest fully while inhaling. This is a medical condition characterised by paroxysmal wheezing respiration dyspnoea. 
Homeopathy for Asthma-
When it comes to the treatment of Asthma, Homeopathy is much better at treating asthma. It is in stark contrast to allopathy, where inhalers and steroids are used to suppress inflammation. Homeopathic medicines do not aim at just reducing inflammation. They also intend to cure the basic cause of the recurrent inflammation. This way, not only the symptoms of asthma are treated but the incidence of asthmatic attacks is completely eliminated. With a couple of months of Homeopathic treatment, you will be able to live a disease-free and medicine-free life. It is worthwhile to mention here that all Homeopathic remedies are natural and do not contain any chemicals. That is why these purely natural homeopathic remedies do not have any side effects at all. Here is a list of the top homeopathic medicines for asthma, along with the symptoms when they are used-
Ipecac: Ipecac is used in treating asthma, where the patient experiences symptoms like heaviness and tension around the chest area. Sudden wheezing, suffocation is experienced followed by other symptoms like motions, vomiting and gagging. The cough remains constant, and the chest gets filled up with phlegm. Cold and perspiration is also likely to be experienced. A patient may feel as if a lump is present in the chest. Increased salivation is also indicated.
Arsenicum: Arsenicum is an efficient homeopathic medicine, which treats asthma attacks, which take place after midnight. The patient is anxious, restless, and cannot sleep because of the fear of being suffocated. In such cases, the patient dozes off a bit, and wakes up with great burning sensation and sore feeling in the chest. Arsenicum is prescribed during chronic stages of asthma, usually in elderly people.
Nux Vomica: Nux Vomica is used when asthma attacks occur due to gastric disorders and during simple spasmodic asthmas. People who consume an excess of caffeine or alcohol are more likely to experience such attacks. A constricting feeling in the lower chest region may be experienced. These attacks commonly occur during the morning.
Kali Bichromicum: This homeopathic medicine is used is asthmatic patients where the asthma attacks occur because of potashes. The attacks generally occur between three to four a.m. in the morning. The patient gets compelled to rise from sleep and sit up in order to breathe. A stringy yellow mucus may be produced, and the patient feels a lack of air in his chest.
Natrum Sulphuricum: This is another effective medicine for treating asthma. The symptoms of asthma treated with this medicine get worse in damp weather. Most asthma attacks occur with a rattling sensation being felt in the chest. Bowel movement may become loose after this type of asthma attack. Alcohol and aerated drinks make the symptoms even worse. Such attacks are common in the morning with the production of a green mucus.
Homeopathy has no side effects and treats the underlying cause of asthma. You should consult a homeopathic practitioner before starting homeopathic treatment for asthma.
