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 have been diagnosed with asthma, it is important for you to know about the most common triggers of asthma. Asthma is a medical condition, which is characterised by paroxysmal wheezing respiration dyspnoea. It causes breathing difficulties, tightened chest and coughing.

Children having large amounts of cockroach droppings in their homes are more likely to develop childhood asthma. Dust exposure may lead to dust mite allergy in asthmatic patients.

Food which triggers asthma
Certain food allergies may lead to isolated asthma, where other symptoms are absent. Patients with food allergies can exhibit asthma as a part of anaphylaxis, which are food induced. The common food items which are associated with allergies include eggs, peanuts, cow milk, soy, fish, wheat, shrimps, salads and fresh fruits. Several food preservatives also trigger asthma. They may include sulfite additives such as potassium bisulfite, potassium metabisulfite, sodium sulfite, sodium bisulfate and many others. These are commonly used in food processing and trigger asthma in sensitive people.

Asthma induced by exercise
Strenuous exercise may lead to the narrowing of the airways in maximum people having asthma. Exercise acts as a primary trigger for asthma symptoms in many people. Patients having exercise induced asthma are likely to feel chest tightness accompanied by coughing and breathing difficulties after completing an aerobic workout session. Although the symptoms subside, they may reoccur within some hours. You should warm up properly and slowly before a rigorous workout session to prevent an asthma attack.

Smoking
People who smoke are more likely to have asthma. If you have asthma and still smoke, the symptoms of wheezing and coughing worsen. Pregnant women who smoke increase the chance of wheezing in their to-be-born babies. You should absolutely quit smoking if you have asthma.

Infections which trigger asthma
Several infections such as cold, bronchitis, flu and sinus may cause asthma attacks. The respiratory infections, which are viral or bacterial, are a common cause and trigger asthma, especially in children. Asthma is also associated with severe heartburn. According to studies, more than 85% people with asthma also suffer from heartburn. This is a condition known as gastroesophageal reflux disease or GERD.

How to diagnose asthma in children

Asthma in children under the age of 5 is a matter of concern. It is not a rare disease and early diagnosis is important. Common signs of asthma in children are:

1. Recurring bronchitis
2. Wheezing
3. Discomfort in the chest
4. Coughing
5. Trouble breathing

While some children have persistent yet mild symptoms, some children have severe attacks at times. Seasonal allergies and smoke make the symptoms worse.

What to notice?
While feeding an infant, if you notice that your child is facing shortness of breath, it might be a symptom of asthma. In a toddler, if your notice a decreased desire to run and play, or easy fatigue, then this could be a symptom of asthma. Asthma attacks for many children under the age of 5 are worsened when they catch cold or have any other respiratory infections. All these, if noticed should not be ignored and your child's pediatrician should be consulted.

The above mentioned symptoms were mild. Some children have it worse and the attacks can be life-threatening, needing immediate treatment. If your child is under the age of 5 and you see them doing one of the following, contact emergency services immediately:

1. Trouble in speaking because they have restricted breathing
2. When they are breathing in, the effort is so much that the abdomen is getting sucked in
3. Gasping for air.

Diagnosing asthma in a child can be tricky as symptoms like coughing, wheezing, etc can be for other conditions also. Once a child is a little older and if the symptoms persist, breathing and lung function tests are taken to gauge the situation.

How To Diagnose Asthma In Children, Before It Attacks?

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

It is no longer so surprising to read about alarming air pollution levels in our cities. On more than one occasion, these levels have risen above the danger levels. For some people, this may simply create an annoying fog that makes it difficult to see. For others, it can cause serious health issues. Air pollution is one of the most common reasons for the growing instances of asthma and allergies. Children are most susceptible to such diseases caused by air pollution.

Asthma and Allergies
Asthma can affect children even before their fifth birthday and the condition is characterized by breathlessness caused by a constriction of the airways. While the root cause of asthma is unknown, it is usually seen that asthmatic patients are more sensitive to others to particles in the air such as pollutants, dander, dust, smoke etc. Thus, the airways construct as a reaction to these allergens. Changes in the weather, a sudden cold draft or the flu can also aggravate asthma.

Can you Protect Your Children from Asthma?
Wheezing, panting, finding it difficult to breathe and a persistent cough are some of the signs of asthma. If you notice these symptoms, you must consult a doctor immediately. At home, here are a few things you could do.

Avoid exposing your children to smoke: Do not smoke around your children or allow others to smoke around them. If you cannot give up the habit, wear a smoking jacket when you smoke and take this off before you play with your children. When you ll go out, drive with the windows up so that your child does not inhale exhaust smoke. Set your air conditioner to circulate air within the car itself.
Dust often: Try and keep your home as dust free as possible. Use a wet cloth to clean so that the dust does not fly in the air. Wash all your bed linen once a week. Carpets and rugs should be vacuumed regularly or dusted outside. It may also be a good idea to invest in dust mite impermeable covers for your child s mattress and pillows.
Keep your Pets clean: If you share your home with pets, bathe them once a week and brush them daily. Do not let them climb on to the furniture or your beds. Also, avoid having their toys lie on your beds.
Wear a face mask: Try and time your child s outdoor activities when the pollution levels are low. Buy yourself and your child a face mask that will filter the air they breathe in. These should be worn whenever they play outdoors.
These simple steps could help your child be healthier and can prevent asthma and other such allergic reactions.
