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 that can flare up anytime; be it at your child's soccer practice or during the middle of the night. Whenever the condition sets in, it leads to your child struggling for breath. For a parent to witness this situation can be hard; but you should know the techniques to keep the situation under control.

2. Keep records of the following: It is good to have an action plan ready for your child when the bouts of asthma strike. When you visit the doctor to discuss about your child's condition then make sure that you have these records at hand.

The triggers that caused the bout of asthma
How many times did your child have wheezing episodes?
The number of times your child has been admitted for the same reason
The medications that your child is currently taking, dosage and/or whether they have been changed
How often does he/she need medications if he/she has acute symptoms?
3. Knowledge of the test your child may require: Asthma control test is a type of test that allows parents and children to grade asthma symptoms without a doctor. A pulmonary function test is used to detect the capacity of the lungs and flow of air.

4. See how your child responds to the treatments: You should consider changing the treatments for your child if he/she has recurrent symptoms of asthma attack and require frequent visits to the Emergency Room even after taking medications for an extended duration.

5. Long term treatment plans require patience: Any asthma treatment plan requires patience as they might not immediately cure symptoms.

How to Manage if Your Child Is Suffering From Asthma

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

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 lungs are made of pipes - starting from the nostrils all the way to the fine tubules in the lungs, through which the air we breathe passes through. The inhaled air also contains a lot of other particles - dust, pollen, virus, cigarette smoke, etc. Very often, the body is allergic to one or more of these particles, and the bronchi are constantly irritated and inflamed due to their sustained exposure. This causes allergic bronchitis which is identified by symptoms like chronic coughing, difficulty breathing, hoarseness, nasal congestion.

Ayurveda believes that the human body has 3 doshas or bio elements - vata, pitta, and kapha. Any disease is believed to be due to one of these being affected. Allergic bronchitis is believed to be an issue with vata.
1. The most effective treatment for bronchitis is believed to be a glass of milk mixed with 1/2 teaspoon of turmeric powder in it. This mixture is believed to be most effective when taken on an empty stomach and can be had 2 to 3 times a day.
2. Equal portions of powders of dry ginger, long pepper, and black pepper can be mixed with honey to make a smooth paste. This can be had 2 to 3 times a day to see wonderful results.
3. One-half teaspoon of licorice powder mixed in 1 cup of water can be boiled, cooled, and stored to be consumed through the day.
4. A creeping plant known as somlata (ephedra vulgaris) is found to be highly efficacious in relieving asthma. This grows in western himalayas in abundance and is sent in hundreds of tonnes to western countries where ephedrine is prepared from it. The powder made from the whole plant, after drying in the shade and is given in the dosage of 100 to 250 milligrams, mixed with honey or water at the intervals of 8 to 4 hours.

Other formulations

Kapha katari - literally translates as phlegm cutter, this works immediately. The powder needs to be wrapped in betel leaf and chewed slowly. Continue with another 4 doses over the next 24 hours.

Kanakasava - the extract of datura is very effective in halting bronchitis but needs to be taken under medical supervision only. This is habit-forming and therefore, needs to be used cautiously.

In addition, follow these general considerations too:
1. Avoid or minimize exposure to known allergens, cigarette smoke and pollution
2. Drink about 8 to 10 glasses of water to help form a thin mucous
3. Avoid dust in the bedroom, avoid feather pillows
4. Regularly vacuum clean the house
5. Do yoga, especially the breathing asanas which are very beneficial for bronchitis patients
Allergic bronchitis is a chronic condition, and acute attacks can be avoided by following some of the pointers mentioned above.
