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.

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.

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 - Common Triggers Behind it?

 Asthma  is a serious expiratory disorder, whereby, the patient faces difficulty in breathing or dyspnoea due to various factors such as allergies, bronchial infection, anxiety or stress and occupational hazards. In all the cases, it leads to excessive bronchial spasm and mucus accumulation, plugging the bronchial which leads to paroxysms and the patient starts panting heavily. But it is completely chronic without any complications. 

Although allopathic measures such as inhalers and steroids can temporarily help to control the situation, yet, homeopathy has proved even more useful for asthma as the treatment is completely natural and does not carry the uncertainty of side effects like the steroids. It not only helps to reduce the intensity of spasms, but also, tries to cure the actual cause of asthma itself. Consequently, after a complete and proper treatment of asthma with homeopathy for a couple of months, it has been found, that the patients are living a happy life without any sign of the disease. Given below are the various homeopathic medicines used for curing asthma:

Arsenic Album   This medicine comes into rescue when the patient is extremely restless, unable to sit or stand comfortably, feels extremely thirsty but is unable to drink too much water, feels suffocated with pain in upper-right chest. Arsenic Album is said to have provided great relief to such patients.

Ipecac   When a patient suffers from vomiting and nausea during these asthmatic attacks, this medicine can prove very useful, especially in children and adults who are a little fat.

Antim Tart   One of the effective medicines for asthma accompanied by rattling cough caused due to eating making the patient feel very weak and sleepy. This medicine is generally suitable for old people and children.

Nux Vomica   This medicine helps patients who suffer from gastric problems due to asthma causing headache and epigastric pain in the stomach region.

Carbo Veg   This medicine helps in cases where asthmatic attacks make the patient s face blue and also cause coldness of hands and feet.

Although above medicines are very effective, yet, they should always be taken strictly under doctor s guidance.

Homeopathy Treatment For 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.
