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 something which affects quite a large number of people. As a matter of fact, up to 20 percent of the population is affected by it. Isn t it surprising that the ways to treat it are not so well known, taking into account how many people it affects? So, wouldn t it be a great idea to learn more about it and learn to treat it in a pretty unique way?

When a person has asthma, the airways of the respiratory system become narrower than they usually are and this, in turn, leads to a shortage of breath. While many people would normally go to a conventional doctor in order to treat asthma, it may come as a rude shock to know that asthma is often triggered by reactions to conventional medicines such as non-steroidal anti-inflammatory drugs, which are also known as NSAIDs. Things are not that straightforward, are they?

Ayurveda is a body of medicine which looks not at just patching up and fixing medical problems, but rather to maintain a high level of overall health. Considering this, it should not be much of a surprise to come to know that when it comes to the treatment of asthma, Ayurveda is not superficial like a lot of other methods of treatment. As a matter of fact, it not only looks at the respiratory system but also at the gastrointestinal system in order to provide a comprehensive solution for a patient who is affected by asthma.

According to Ayurveda, the body is divided into three doshas and in the case of asthma, it is the kappa dosha which is culpable. If the asthma is detected before too long, a fully effective treatment can be undertaken and the patient can be restored to his or her pre-asthma level. However, if there is a significant delay between the time that asthma sets in and its detection, only management is possible.

Foods which trigger asthma are to be avoided like the plague! Examples of these foods happen to be animal products and dairy products such as curd. In addition to this, bananas and sugary foods or sweets, including sugar, in itself, are to be avoided.

A paste of rock salt, mustard oil or clarified butter can help if it is rubbed on the chest. Medicines such as Sitopalaadi choorna are to be taken, with this specific medicine ingested with honey. Kapha kartari addresses the issues with the Kapha and with it, asthma should be on its way to becoming a minor problem pretty soon!

Asthma - Know How Ayurveda Can Help You!

We take the act of breathing for granted, but for many people this simple action can be quite difficult. Difficulty breathing is one of the characteristic symptoms of asthma. This is because of an inflamed, narrow airway. Asthma can be allergic, hereditary, emotional or occupational in nature and can significantly lower the quality of a person s life.

Homoeopathy is a holistic form of treatment that addresses not only the symptoms of a problem, but its root cause. This form of treatment takes into consideration the physical, mental and emotional state of a person. It has negligible side effects and hence can be prescribed to people of all ages. 

Some of the most frequently prescribed homeopathic remedies for asthma are:

Ipecac: This is used in cases where the patient suffers from sudden wheezing, dyspnoea, anxiety and feels a weight on his chest. In such cases, the asthma is aggravated by motion and a constant cough often causes gagging and vomiting.
Arsenicum: Arsenicum is beneficial in cases where the patient is elderly and asthmatic attacks are more frequent after midnight. These patients suffer from anxiety, restlessness, burning in the chest, dry dysponea and fear suffocation. Allergic asthma caused by humidity can also be treated by arsenicum.
Antim Tart: This is prescribed to patients who suffer from a rattling cough with little mucus expectoration. In many instances this cough is triggered by eating and can be relieved by lying on one side. This type of asthma also makes the patient feel drowsy and weak. Antim Tart is especially beneficial for young children and elderly people.
Nux Vomica: Asthma can also be triggered by gastric troubles. In such instances breathing is more difficult in the morning and is marked by a dry cough and a feeling of fullness in the stomach. Nux Vomica is an excellent remedy for such types of asthma. These asthmatic cases also worsen in winters and may be accompanied by a headache or stomach ache.
Carbo veg: This homoeopathic remedy is prescribed in cases where the patient s face turns blue at the time of an asthmatic attack. These patients also suffer from stomach troubles and a cough accompanied by itchiness in the larynx. Along with this, they tend to feel cold, especially in their hands and feet.
Though homoeopathy has negligible side effects, it should not be used to self medicate. Homeopathic medicine should be prescribed only after the doctor has a thorough physical and emotional understanding of the patient.

Asthma - 5 Homeopathic Remedies to Help You Treat it

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?

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.

Childhood Asthma - 8 Signs To Look For!

There has been an intense debate, which is in the loop for years and has been raging back and forth regarding the deficiencies of a vegetarian diet versus the perils of a non-vegetarian one. This heated debate is both accurate as well as unfounded. Probably, that s the entire reason it is still a debate. In fact, if you look into the diet of both groups, you will be able to identify the fact that, there is a space for healthy living in both.

Vegetarian Diet

In a vegetarian diet, the food intake of a person is confined to a large variety of foods derived from plants along with milk and dairy. And, any form of meat and products derived from animals are completely avoided.

Pros

Vegetarians have been noted to consume lesser amount of proteins, but they do not suffer from problems related to a high protein diet, such as osteoporosis (characterized by brittle and weak bones) and kidney failure.
The diet includes high level of antioxidants such as vitamin E & C as well as carotene, which is available in vegetables and fruits.
Additionally, they consume less amount of saturated fats.
Cons

Deficiency of vitamin B12 is common amongst vegetarians, as it is mainly available in meat, eggs and fish. Deficiency of vitamin B12 can yield rare symptoms such as increased fatigue, shortness of breath and a temporary loss of body balance.
Lack of protein, as stated above, along with iron and zinc deficiency is also common. 
Symptoms of protein deficiency can be troublesome and include signs like

Sluggish metabolism
Loss of body muscles (as the body tries to derive the regular protein intake from your muscles, thus making them weak),
Trouble gaining or losing weight
Persistent fatigue
Longer healing time in case of wounds and injuries
Pain in joints
Drastic changes in blood sugar level that might result in diabetes
A weak immune system makes you vulnerable to all kinds of diseases.
Non-vegetarian Diet

A non-vegetarian diet includes all forms of plant foods as well as foods and by-products that are derived from animals, such as poultry, fish, meat, etc.

Pros 

Vitamin B12 is present in adequate level since they are derived from sources such as meat, eggs and fish. Adequate intake of proteins is never an issue for  non-vegetarians
Cons

Meat products are loaded with saturated fats, which increase the risk of heart diseases. Studies have shown that people consuming non-vegetarian diets:
Have shorter lifespan and are more vulnerable to chronic diseases.
Tend to develop diabetes, heart diseases and hypertension.
Usually non vegetarians eat less amount of vegetables and fruits than what is recommended.  
If you wish to discuss about any specific problem, you can consult a Dietitian/Nutritionist.
