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 condition characterized by wheezing and difficulty in breathing. Asthma is a common disease that affects children, teenagers and adults alike. Depending on what triggers an asthmatic attack, asthma can be categorized as four types. These are:

1. Allergic asthma: this sort of asthma usually begins in childhood and is caused by the overproduction of immunoglobulins as a reaction to the allergen. This type of asthma can also be passed on from one generation to another through genes.

2. Infective asthma: this is caused by viral bronchial or upper respiratory tract infections. It is not hereditary.

3. Emotional asthma
Some cases of asthma can be triggered by psychological factors such as stress, grief or anxiety. 
However, it is not clear if this is the sole trigger for asthma.

4. Occupational asthma: exposure to metallic dusts, biological detergents, polyurethane, etc. Can also trigger asthmatic attacks. This type of asthma is called occupational asthma.

A homeopath will not only determine the type of asthma, but will also delve into a detailed medical history of the patient before prescribing medication. Some forms of homeopathic medication that can be used to treat asthma are:

1. Lpecac: this is used to treat asthma in cases where the difficulty breathing is accompanied by a feeling of heaviness over the chest, dyspnoea, constant coughing with no expectoration and cold perspiration. It is often aggravated by motion.

2. Arsenicum: asthmatic attacks that begin in the middle of the night and are accompanied by restlessness and anguish can be treated with arsenicum. This is especially beneficial in cases of chronic asthma in elderly people and habitual dyspnoea.

3. Nux vomica: this is used mainly to treat asthmatic attacks triggered by gastric troubles or be excessive intake of coffee and alcohol. A constricted feeling around the lower part of the chest is another symptom of this type of asthma.

4. Kali bichromicum: asthmatic attacks that wake a patient up in the wee hours of the morning compelling him to sit up, in order to be able to breathe can be treated with kali bichromicum. A stringy yellow mucus expectoration is another symptom of this type of asthma. It can also be used as an effective form of treatment for asthmatic attacks caused by nervousness.

5. Natrum sulphuricum: this is used to treat asthmatic attacks caused by a change in weather. In such cases, the asthmatic attack is accompanied by diarrhea and greenish expectoration. It is usually worst in the early mornings.

Homeopathic Cure for Asthma

Asthma is a disease that can be only controlled and not completely cured. This chronic disease can make one feel breathless and experience chest tightening. Modern medicine has an answer to the stressful symptoms of asthma. A wide range of tools and medicines help a great deal in controlling this disease. Find what tools and medicines can help in bringing down the symptoms of asthma and help one breathe with ease.

Pink flow meter: This small tool helps in measuring the movement of air in the lungs. You need to blow into it and read the number. The result helps in finding out the frequency of doctor visits and the dosage of the medicines. Forthcoming asthma attack too is indicated by this device, and you can see it declining with constant use. In fact, you would slowly stop experiencing any other symptoms. Using the pink flow meter forewarns you about a forthcoming asthma attack.

Checkups: You need to visit your doctor regularly. The frequency can vary. You will be seeing your doctor after every two to six weeks, based on the severity of the disease. If you strictly stick to the instructions of your doctor, you can improve the lung function. You can stay active and sleep well if you follow the medicines. This way, there will be no fear of emergency treatment as the peak flow is almost always above 80 percent in case of complete compliance to medicine. Even if you know your condition cannot be cured, you can keep it in check to lead a healthy life.

Medications: Asthma has to be controlled with two types of medicines. You will need to take fast-reacting medicines and the long-term medications. Providing immediate relief is what the quick-relief medicines do, and reducing inflammation of the airways is what the long-term medicines aim at. While there are pills available, the inhalers play a vital role in keeping asthma patients healthy. Through an inhaler, the medication is administered straight into the airways. This makes it easy to give larger and continuous dose of medicines. In fact, this is the most effective way to prevent and treat the asthma symptoms. Corticosteroids are inhaled with an inhaler and it results in long-term relief. Even if taken daily, patients do not get addicted to corticosteroids. Physicians may also prescribe pills that reduce inflammation of the airways. Short-acting b2 agonists are often prescribed as quick-relief medicines. Asthma-affected individuals must carry the inhaler and the quick-relief medicines with themselves, wherever they go.

Treatment for different age groups: In children, only the quick-relief medicines are prescribed. If required, the long-term medications are used after six years of age. If desired results are obtained, the treatment is stopped after six weeks. Children can also be administered corticosteroids. This may result in slowed growth in a few children but the effect does not last long. In elders, long-term inhaling of corticosteroids can increase the risk of osteoporosis. It is essential to take vitamin D supplements along with it. Also, do not take pain suppressants and anti-inflammatory drugs. Speak with your doctor about taking pills for other diseases. When a pregnant mother is asthmatic, the chances of the child getting asthma are higher. They also suffer the risk of premature birth and low birth weight. Check with your doctor about taking medicines for asthma when you are pregnant. You need to consider the risk and stick to safe medication practices.

Asthma - 5 Homeopathic Remedies That Can Really Do Wonders!

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.
