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 respiratory disease that takes place with a variety of symptoms including breathlessness, wheezing and coughing. It usually occurs when the airways get obstructed, which in turn leads to inflammation of the tubes. So how can you recognise the signs and symptoms of asthma? here is a list of ways!

Risk identification: it has been observed by doctors and medical science that there is no specific reason for the onset of this ailment. It can be caused due to genetic as well as environmental factors. So, in order to recognise the symptoms, you will first of all have to take stock of both these factors. Find out if you have any blood relatives who have suffered from this ailment and try to find out how it started and at what age, so that you can watch out for the same warning signs. Also, if you are more prone than others when it comes to allergic conditions like rhinitis and atopic dermatitis, then you are at risk. Other risk factors also include living in a high pollution zone, as well as being overweight, smoking, working within close range of exhaust fumes and other chemicals, and other such factors.

Symptom identification: to be able to identify whether or not you are at risk, you must identify the potential symptoms including persistent shortness of breath, which may strike regularly. Also, another symptom is not being able to sleep comfortably due to excessive coughing and breath shortness as well as shallow breathing and wheezing. You may also experience some amount of chest tightening or constriction. These symptoms will usually get worse if you happen to be suffering from the flu or a cold. 

Respiratory health: if you are suspecting the onset of this disease, it would be a good idea to watch your respiratory health by observing the rise and fall of your breath when you are doing energy consuming and strenuous activities like exercising or other such tasks. Sports induced asthma is an actual condition that can get worse when your lungs are faced with cold and dry air. Also, if you are facing exhaust fumes and chemicals as a part of your job, then you are at risk of occupational asthma, in which case you should watch your respiratory health very closely. These symptoms can also get worse when you are around animals and pets due to the allergens that may trigger wheezing and coughing. A lung function test can be conducted by the pulmonologist in case you are suffering from any of these symptoms and conditions on a persistence and prolonged basis. 

Knowing and reporting your symptoms to the doctor is important for getting timely treatment.

How to Recognise Asthma?

Asthma is an inflammatory disease, which affects the airways of your lungs (respiratory tract that pumps oxygen into the lungs). It is long term in nature. It is characterized by shortness of breath, coughing and wheezing. It occurs a few times a day or a few times a week depending on the person it affects. Sometimes it worsens during the night.

What triggers Asthma?

Airborne particles such as dust mites, mould spores, pollen and cockroach waste.
Infections in the respiratory system such as a common cold.
Cold air can also trigger asthma.
Physical or outdoor activities which make you pant such as running, skipping, jogging and jumping can cause shortness of breath, thus triggering asthma.
Pollutants and irritants in air such as smoke.
Some medications can also trigger asthma.
Stress and nervous attacks (panic attacks) also trigger asthma.
How to manage asthma better by changing your lifestyle:

Try to avoid keeping animals in your houses such as dogs, cats and rabbits. Many times animal fur, waste, urine and saliva contains particles which can cause allergic reactions and make you cough uncontrollably. This, in turn, triggers asthma attacks. If you have pets try keeping them away from your bedroom.
Dust mites also cause allergies which trigger asthma. So wash your carpets, rugs, bed-linen and pillowcases in hot water.
Bugs and insects such as cockroaches are not only unhygienic but can also trigger asthma. Cockroach droppings near your bed, kitchen and food are dangerous and you should call an exterminator to get rid of these bugs.
Sometimes, the heavy fragrance also aggravates your respiratory tract and triggers shortness of breath. Avoid using heavy perfumes, deodorants and room fresheners.
Pollution also triggers asthma. Dust particles come out from the vehicles and mix with the air. If this air is inhaled, it might trigger uncontrollable asthma. So try to cover your mouth with a cloth when you step out of your house.
Asthma can be very severe and can bring many hurdles in your day to day activities. Changing your lifestyle and certain habits can reduce asthma to a great extent.

Lifestyle Changes to Manage Asthma Better

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.

Allergy or Asthma Cure in Homoeopathy

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.
