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. By identifying and reducing your exposure to several asthma triggers, you will be able to manage or control your asthma symptoms and the frequency of your asthma attacks. Here are the most common triggers of asthma you should know about:

Allergies that trigger asthma
Allergies, are common problems and over 80% of people are suffering from asthma and are allergic towards substances like weed pollens, animal dander, dust mites, mould and cockroach particles. 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.

Asthma - Common Triggers Behind it?

Asthma, the long term inflammatory disease, affects the airways of lungs. A number of symptoms, including obstruction of air flow into the lungs, which can cause breathlessness, coughing, wheezing, allergic reactions and swelling of the tubes, points to it. The causes include genes as well as pollution in the environment which is resulting in an increasing number of cases. The diagnosis is usually done with a spirometry and the treatment is a long term process. 

Women who suffer from asthma have to be especially vigilant during pregnancy as it can lead to a number of complications including less air passage to the foetus. This can result in a slow rate of development and certain anomalies in extreme cases. So how can a pregnant lady manage asthma? here are a few tips:

 Involve pulmologist: to begin with, the obstetrician and the pulmonologist must both be well aware of the situation. The pulmonologist must be given detailed information with regards to allergies as well as past treatment and medical history so that the treatment is done systematically to prevent an asthmatic attack and any complications to the foetus. 
 Lung function: during pregnancy, the doctor must monitor lung function carefully with monthly check ups to ensure that the right amount of oxygen is reaching the foetus. This is done because the severity of asthma changes in most women during pregnancy. A spriometry or peak flow metre can be used to measure the lung function. Also, the foetal movements must be monitored on a monthly basis, or rather, once every 28 days, to be more specific. 
 Influenza: flu is a common outcome of asthma, especially when it becomes severe during pregnancy. The onset of flu or influenza must be prevented at all costs with the help of a flu vaccine that will be effective at least for a season at a time. It is a pregnancy safe injection. 
 Triggers: there are many things that may trigger an asthmatic attack or an allergic reaction that can lead to the same. Ensure that you do not suffer from these triggers by avoiding dust, pollen, tobacco smoke and varied other substances that can lead to choking and wheezing. 
 Medication: one must ask the doctor about pregnancy safe inhaled corticosteroids that one can take during pregnancy if and when the need arises.

 It is recommended to take medication for asthma during pregnancy only after a consultation with the doctor. Also, do not reduce the dose of the medicine unless your doctor has recommended a change.

How to Deal With Asthma During Pregnancy

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. 

Treating Asthma With Homeopathy

The term asthma and bronchial asthma are often used interchangeably. Bronchial asthma refers to the chronic inflamation of the airways either due to some internal or environmental allergen. This leads to the narrowing of airways, which makes breathing difficult and blocks air from entering the lungs. Children are most affected by this condition as the immune system is still in the process of maturity and often grows out of it as they age. However, if not treated, this can lead to many complications like respiratory failure and can prove to be fatal. Asthma cases often spike in winter months and in the flowering season. It can also be triggered by second hand or passive smoke, stress, sudden unaccustomed physical exercise, food additives, dust, house mites, perfumes, certain drugs and many other allergens. A family history of asthma, allergic rhinitis, atopic dermatitis and other allergic conditions can also increase a child s risk of suffering from this condition.

Some of the most noticeable symptoms of bronchial asthma include:

1. Wheezing 
2. Shortness of breath 
3. Excessive coughing that worsens at night 
4. Tightness of the chest 
5. Lowered energy levels 
6. Rapid breathing 
7. Tiredness 
8. Indrawing of chest and lower neck

These symptoms often worsen after exercising. Lung function test and Chest X-ray are often used to confirm a diagnosis of bronchial asthma. Once diagnosis is being confirmed, it should be categorized as per severity. Your doctor may prescribe medication in the form of pills and inhalants as per the category of disease. It is important to note that these cannot cure asthma, but can help manage it. Inhalers deliver low doses of steroids directly to the lungs to reduce inflammation and other inhaled medication like Beta 2 agonist will open the airway by relaxing the muscles of airway. Children suffering from asthma must be taught how to use the inhalers and should always have it with them. In the case of school going children, their teachers should also be informed about the condition. Parents should also know how to keep it, use it and clean the device in a proper and hygienic way.

In very small kids those inhalational medication can be given by face mask and spacer, but as the age grows or in case of elder children above 6 years of age, they can directly take the medication from spacer. Those children who are already on inhalers, but still face asthma attack , for them nebuliser is the better choice to manage the emergency. It will make the liquid medicine into mist and enters into the air passage easily and work promptly.

In addition, certain lifestyle changes can also help reduce the frequency of asthmatic attacks. Avoid going outdoors on windy days or days when air pollutant level is high. Reduce the child s exposure to allergens like pet hair, dander and dust by dusting and vacuuming on a weekly basis. Avoid the use of humidifiers inside your house as moist air can promote the infestation of dust mites. Try to keep the child in a room with adequate air and sunlight. Take plenty of green leafy vegetables and fruits, which contain lots of vitamins and minerals. If possible get your child to wear cover his or her nose and mouth while in outdoors.
