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 chronic lung condition wherein the air passage gets blocked or constricted due to the production of extra mucus. It is an age old condition which has been creating problems for people since a long time. Despite the seriousness of the condition, there are various myths people tend to believe about asthma.

Here are a few myths about asthma and the usage of inhalers:

Regular Usage of Inhalers is Addictive: This is a total myth. Using inhalers is not at all addictive, it is a necessity. Just because you use your inhaler regularly does not mean you are addicted to it.  Just like brushing your teeth every day isn't an addiction, taking your daily medicine from an inhaler isn't an addiction as well. Using an inhaler will just help you with your asthma condition.
Oral Medicine Gets Better Results than Inhalers: Absolutely not. In fact, it is proven that inhalers give better results than oral medications. Oral medication takes longer to act during a sudden asthma attack while inhalers deliver the drug directly to the lungs.
Inhalers Are Meant For Severe Asthma Cases: Well, this again is not true. Inhalers are used for treating asthma. Period. Asthma is a condition where your lungs inflame which is best cured with steroids, and the easiest way to have steroids administered to you is through the inhalation method. When you use the inhalers, the steroids are delivered directly to your lungs. They also have a minimum number of side effects when administered through inhalers.
Asthma is Curable: You might tend to think that asthma can be cured with the help of proper medications. You might think that asthma is not a constant condition. But it is not what you think. The symptoms of asthma might not be present all the time but that doesn't mean you do not have asthma. Asthma is a long-term condition where the airways swell up causing you to suffer from breathlessness. If you suddenly stop taking your daily medicines because the symptoms have not surfaced, then it will take you a long time before you will be able to totally recover from the next attack you suffer from.
If you have asthma, remember to take your medicines daily and timely. 

Debunking Asthma Myths

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

Bronchitis occurs when the bronchial tubes become swollen due to an ailment or any kind of infection. These tubes are a part of the respiratory system and usually join the lungs. There are two types of bronchitis - acute bronchitis and chronic bronchitis. A virus or bacterium usually causes acute bronchitis. It shows up after a person has had a respiratory disease. The most common symptoms of this disease usually show up when a child has flu or cold. A blazing throat, a feeling of being sick and mucus draining from the sinuses usually describe the disease.

Homeopathy is a very effective treatment for bronchitis. In fact, it is the most effective treatment. Homeopathy has been successful in treating some exceptionally extreme cases of bronchitis. It functions admirably in both acute and chronic bronchitis. Here are a few treatments for acute bronchitis for kids that have proven to be beneficial over time:

Hepar Sulph is one of the best homeopathic medicines for bronchitis where a person experiences increased sensitivity to cold. Chilly air and exposure to the cold in any form is impossible to be tolerated by the patient. It energizes cough quickly. Hepar Sulph cures situations where even if a single part of the body is exposed to the cold like a hand or a foot, cough begins immediately.

Bryonia, on the other hand, is helpful in situations where a person feels extremely thirsty, yet may only have a few sips at a time. The mucous layers and the mouth become extremely dry. Even the cough is very dry in such cases. There is a pain in the abdomen and headache while coughing.

Pulsatilla is great in situations where the patient coughs up a lot of greenish or yellowish mucous. Cough is more irritable while resting and the person cannot rest or sleep because of the same. The patient is usually not at all thirsty in this situation.

Arsenic Album is one of the best homeopathic medicines for symptoms that include a feeling of weakness along with other signs of bronchitis. Extreme wheezing and cough increase after nighttime and makes it difficult for the person to sleep. Along with extreme weakness, restlessness may also occur. The patient feels parched and frequently drinks little quantities of water.

Antim Tart is useful when there is a lot of mucous in the abdomen and chest. Despite the fact that there is a lot of mucous in the abdomen, little is disposed off. Cough in this situation is aggravated while a person eats. However, Antim Tart tends to find relief from the same. Patients usually find it very hard to bring out the mucous in this situation.

Treat Acute Bronchitis In Kids With Homeopathy!

Asthma is a distressing condition during which people find it difficult to breathe as the bronchi or tubes carrying air to lungs swell up. This happens when mucus inside bronchi comes into contact with an allergen like a pollutant or dirt causing symptoms like wheezing, coughing, more mucus production and difficulty breathing. There is no cure for asthma. As of now, it can only be managed. But managing asthma becomes really difficult during low air quality days, especially during winters when it s cold and dry.

The most common air pollutants are gases like sulphur dioxide, nitrogen dioxide, vehicle smoke, and suspended particles. Each one of them can trigger an asthma attack by itself because of its deleterious effect on the lungs. The smaller the particulate matter is, the more dangerous it becomes as these particles get lodged in the air sacs inside lungs, causing not just asthma from worsening but also fatal diseases like lung cancer.

So, most asthma patients suffer from frequent attacks due to air pollution. How can these attacks be prevented? Here are some tips:

According to research, asthma can be managed by making modifications in everyday life. On high air pollution days due to ozone, for example, asthmatics tend to experience more lung inflammation. If you are an asthmatic, you should reduce time spent outdoors, especially doing strenuous activity in the mornings and evenings. Keeping medications on hand and using those at the very start of an asthma attack also helps. There should always be a plan in place to lessen the chance of an asthma attack on poor air quality days starting from a rescue inhaler to preventive medication if your doctor feels you need it.
Stay hydrated and breathe through the nose. Dehydration is dangerous for asthmatics especially when air quality is bad. In this case, lungs can become badly affected because they need right temperature and levels of water to work properly. It s crucial to breathe through the nose only and not the mouth as the air breathed in from the mouth can be very cold and dry and can cause even more inflammation of the lungs.
Know your asthma triggers and change lifestyle. Avoiding your triggers is key to managing asthma. If traffic fumes are a trigger, it s best to change the route you take to work to manage your asthma. If you don t know your triggers look back at your last asthma attack and remember what you were doing. Did you pet your dog? Write a diary and discuss with your doctor on how to avoid your triggers. Use a face mask when outdoors to limit exposure to allergens. 
Track your asthma to recognise early signs of asthma. If you know that it s getting worse, you should have a fool-proof plan in place.

Air Pollution - Tips to Prevent Asthma From Worsening!

Has your child been coughing frequently? Is the cough chronic in nature, making your child breathe rapidly and does he/she complain about a tightened chest? These symptoms signify that your child is having asthma. Asthma is a medical condition characterized by paroxysmal wheezing respiration dyspnoea. It is common in children and an affected child experiences difficulty in breathing, and a whizzing sound is produced, especially during expiration. Asthma may lead to severe health complications and needs immediate diagnosis and treatment.

Diagnosis: The diagnosis of asthma is based on the symptoms, medical history and a physical examination of the child.

The different modes of asthma diagnosis are as follows:

    Medical history and symptoms: You must tell the doctor about any history of breathing trouble with your child or whether there are chances of other inherited health conditions. You must explain your child's symptoms properly, which may include coughing, wheezing, chest pain or tightness and others if observed.
    Physical examination: A physical exam will be carried out in your child where the doctor will listen to his heart and lungs, and look for eye or nose allergies.
    Medical tests: A chest X-ray of the child has to be carried out, along with a simple lung function test known as spirometry. This test measures the amount of air present in the lungs and determines how fast it can be exhaled. Spirometry enables a doctor to determine the severity of the asthma. Some other tests are also carried out for the identification of asthma triggers. They include allergy skin testing, blood tests and X-rays to know if sinus infections are affecting the asthma. An asthma test determines the amount of nitric oxide in your child's breath.

Treatment: Based on your child's severity of asthma symptoms and his medical history, the doctor will provide you with an action plan to treat the same. This action plan explains all the medications your child requires, the dosage and schedule of the medicines. The plan also includes points on what to do when the asthma worsens and when an emergency treatment is required. Anti-inflammatory drugs are prescribed to children who require bronchodilator medication. All asthma medicines used by adults can be used in case of children but in lower dosages.

You should give the asthma medications to your child using a home nebulizer or a breathing machine. A nebulizer delivers asthma drugs by transforming them from liquid to a mist. The child gets the drug by breathing it via a face mask.

In order to control and manage asthma in children, they must avoid the triggers and should keep away from any source of smoke. A doctor must be consulted to know about the best diagnosis and treatment methods.
