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.

What is Allergic Asthma?

Allergic asthma is the condition in which the symptoms of an asthmatic attack appear after exposure to certain allergens. 90% of the cases of asthma in children are allergy driven, while in adults, the percentage is said to be around 50%.

An allergy happens when an individual's immune system exhibits massive reaction or fights vigorously against substances like pollen, dust, animal dander or certain other minute particles which are actually not harmful to the body but are considered so by the immune system.

Symptomatic changes in cases of allergic asthma:

If the symptoms of an asthma attack occur only when you are subjected to these triggers or irritant particles, your case is allergy driven.

In such cases, the airway reacts aggressively to the entry of such allergens.

The airway muscles tighten up and inflammation is observed.

Breathing becomes painful and compromised, and mucus accumulation sets in very quickly.

Coughing is a common phenomenon, as the body tries to expel the mucus accumulated.

The allergens mentioned above are not the only triggering agents. Basically, anything that causes irritation could trigger an allergy and an asthmatic attack thereafter. Symptoms in the case of allergy driven asthma are more or less the same as seen in other asthmatic cases.

Confirming the cause of asthma as allergic or not:

The doctor would give you a much better clarification on whether you're asthma is allergy driven or not. There are pretty much two ways to decipher the same:

One is to administer a tiny amount of allergen to the skin and making a note of the reaction to that. Whether the reaction is a normal one or an aggressive one would tell if an individual has an allergy or not.

Specific IgE test may be done to confirm the cause, or to test the presence of an allergic reaction in the individual.

All your queries pertaining to allergic asthma and asthma, in general, are more than welcome.

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.

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.

Asthma - Common Triggers Behind it?

Asthma is a chronic lung disease that inflames and narrows the airways.  The narrowing of the airway causes recurrent asthma attacks, wherein air flow to lungs is obstructed. Asthma causes recurring periods of wheezing, chest tightness, shortness of breath, and coughing. It cannot be completely cured but it can be helped with minimizing triggers

The triggers can be different for different people. Most common triggers come from:

1) In house - Mold (fungi), dust mites, cockroaches, pet dander.

2) Outside - Air pollution, smog, cigarette, smoke, paint fumes, chemicals, sprays, pollen, industrial dust

3) Allergies - Peanuts, eggs, fish, lactose and food preservatives

4) Other Triggers - Physical exercise, anxiety, agitation, respiratory infections, medications like aspirin, ibuprofen, etc.

Here are top home remedies to control the attack and keep their frequency and intensity low.

1) Ginger - Ginger helps a great deal. You can consume crush it, mix its juice with honey and consume it or boil it in water and drink. 

2) Honey - Mix a spoon of honey with 1/2 teaspoon of cinnamon powder and have it right before bed. Also, you can add a spoon of honey in warm water and sip on it during the day. Honey and ginger juice in equal parts is very soothing too.

3) Figs - Having figs that have been soaked overnight helps in controlling asthma. Consuming dried figs helps in flushing out the phlegm from your respiratory tract.

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
