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 severely affects the lungs. The airways become narrow and the lungs become inflamed. Its characteristic features include bronchospasm, reversible airflow obstruction and variable and recurring symptoms such as coughing, wheezing, shortness of breath and chest tightness. This might be caused up to 2 to 3 times a day.
Causes
Causes include:
1. Daily use of paracetamol
2. Vaccines
3. Daily use of antibiotics
4. Caesarean sections
5. Asthma in family

Asthma is usually triggered by:
1. Tobacco smoke
2. Exercise
3. Polluted or poor air
4. Cold air
5. Emotional stress
6. Allergies

Homeopathic treatment
Asthma should be preferably treated using homeopathy. It is safe for most age groups. Asthma is a chronic problem that is best treated by a qualified homeopath. While few cures are found in numerous home use packs since they can treat a number of problems, the effective treatment of asthma usually needs potencies and changes of cures more than the extent of a prescriber and a home kit. For best results, the monitoring of a qualified homeopath should be sought. The homeopathic cures required for asthma change according to the signs of the sufferer. Some of them are listed below:

1. Arsenicum album (ars.): symptoms requiring the use of this medication include wheezing with dry cough and asthma caused due to cold air. Upon application, the person will be anxious and restless and the condition worsens after midnight. Sometimes, it might result in exhaustion. There is a chilling sensation and they will crave for warmth. Patients required ars. Will be critical, anxious and afraid of being alone.

2. Kali bichromicum (kali-bi.): symptoms that require kali-bi include asthma with stringy and sticky mucus. The patients feel chilly and after a while they get sick. The respiratory tract often is infected with mucous membrane infections. Ulcers are an additional infection.

3. Antimoniumtartaricum (ant-t.): uncomfortable breathing and wet cough with mucus require this medication. It solves many issues that accompany difficult breathing. In severe cases, heart failure is possible.

4. Grindelia (grin.): key symptoms are dry cough and possibility of wheezing. It may be accompanied by rattling respiration, chronic bronchitis and suffocation during sleep.

5. Phosphorus (phos.): upper respiratory tract infections cause asthma that ends in the chest. This causes coughing and wheezing.

Other homeopathic medicines for treating asthma are nux vomica (nux-v.) and pulsatilla pratensis (puls.).

Homeopathic Treatment for Asthma

Air pollution is known to take a toll on the lungs of even the healthiest adults. So, it comes as no surprise that the effects of this pollution on the lungs of children is deemed as a grave situation, full of health hazards including the onset of Chronic Obstructive Pulmonary Disorders and conditions like asthma and other lung disorders. Read on to find out more about the link between air pollution and its effect on the lungs of children.

Children's Lungs: Mostly, all the organs of a child's body are considered delicate and not fully matured until the child reaches a certain age. The main and largest part of the child's lungs will usually grow only after the child is born, much like the arms and legs. In fact, it is a medically proven fact that about 80% of the tiniest of air sacs grow after the child's birth, these are called the alveoli and they facilitate the transfer of the oxygen into the bloodstream with a life-sustaining function that is built into our lungs. These alveoli continue to grow until the child becomes an adult. 

Immunity and Infections: Like the lungs of the child, the immunity of the child is also still in its growth phase, and is very much, unlike the immunity that an adult enjoys. This makes the child more susceptible to infections that are usually carried by air pollution in today's day and age of urban living when myriad pollutants are sent into the air every single day. Also, since children play outdoors more often and spend more time breathing in this air, they are more prone to these infections and lung or respiratory ailments due to this reason. Various studies and tests have shown inflammation in the respiratory passages caused by deposits of carbon dioxide emissions in the lungs of children.

Symptoms: Usually, the very first symptoms that show that air pollution is affecting your child's lungs can be seen when persistent coughing and wheezing sets in, without any proper reason. Also, when the child faces bronchial infections time and time again, all these are indicators of hazardous effects of air pollution in children.

Respiratory problems: Apart from respiratory problems, which can lead to asthmatic attacks, hay fever and allergies as well as other COPD ailments, there are other related dangers as well. These can happen when constant choking and obstruction of oxygen due to pollution becomes a regular affair. These include stroke and brain damage which can eventually also lead to a higher risk of dementia. 

How can you protect your child during such times?

Restrict outdoor activity for the time being, especially during the early morning and evening
Make sure that your child wears a face mask when outside, preferably N95 or 99
Use air purifiers at home 
Go green and use indoor plants that can remove indoor toxins
Boost your child's immunity
Lastly, keep a track of air quality index in your locality

Pollution - How It Can Affect Your Child's Lungs?

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

You must not let the cold and dry air worsen your asthma symptoms. The air that blows during winter time greatly affects people with sinus and respiratory troubles, and all these factors contribute to worsening asthma attacks. But thankfully, there are a few tips that can be followed to curb down asthma and enjoy a lovely winter.

Washing your hands: Doing this frequently with soap and water is one of the easiest and most effective ways of avoiding the spread of cold and other diseases. You must also inculcate this habit among your children, and when you are outside, you should practice using a hand sanitiser and sanitising wipes.
Getting a flu shot: The Centre for Disease Control and Prevention (CDC) advises that all people over the age of 6 months should get their dose of the annual flu shot for protecting themselves against the flu virus. This will help keep your asthma in check.
Avoid sitting by the fireplace: Though it sounds cosy, you should refrain from sitting by the fireside if you have asthma. Burning wood is quite similar to burning tobacco and it can irritate your lungs to a great extent.
Keeping your mouth closed: Though most people are taught this since they were children, they tend to forget it or ignore it. Keeping the mouth opened is more than a social disgrace, and it even affects your lungs adversely. You can wear a scarf for covering up the nose and mouth as it would help in making the air you breathe warm.
Replacing filters: The heating system of your home may be blowing out dust and debris throughout the house, particularly when you operate it after a long time in winter. Therefore, it is imperative to clean and check the condition of the filters and replace them if necessary.
Exercising indoors: The days when it is bitterly cold outside, it is recommended to exercise indoors in a fitness club or a gym instead of doing it in the open air.
Warming up before exercising: People who are affected with asthma are able to recover faster and have a greater lung function after working out when they are warmed up. Therefore, you should try to warm up for at least 15 minutes before exercising.
Preventing asthma flares: Before you head outside, take a dose of your asthma medication and your inhaler as these will help in opening the airways and give you the necessary protection.
Having an asthma action plan: Regardless of whether it is summer or winter, you should be aware of what you should be doing in times when the symptoms flare-up.
Taking your medications: Finally, you should work with your doctor towards understanding the cause and symptoms of your asthma conditions and follow his recommendations closely to avoid recurrence of such problems.
With all these tips, you can expect to spend a happy winter. But if anything goes wrong, seek medical assistance immediately.

Asthma - 10 Ways You Can Control It!

Asthma is the most common chronic condition for women in pregnancy. While Asthma control can affect pregnancy, pregnancy too can affect Asthma. Yet while pregnancy does not beget Asthma, neither does it abate.

Nevertheless, Asthma management during pregnancy is very important. Improper Asthma management, especially in difficult Asthma, during pregnancy may imperil both the mother and the child.

Along with taking the right medications, Asthma patients also need to avoid exposure to Asthma triggers.

Avoiding Asthma Triggers

Asthma triggers may be different for different people. In general, one or a few of the following act as Asthma triggers:

Allergens like pollen, dust mite etc.

Smoking

Certain exercises

Certain occupational exposure

Pollution

Certain drugs like  blockers, aspirin etc.

Alcohol, dairy products, orange juice, peanuts etc.

Additives like tartrazine, monosodium glutamate etc.

Certain medical conditions like gastric reflux, rhinitis etc.

Apart from avoiding these Asthma triggers, she would also need to follow the instructions of her gynecologists. She should always be concerned that if the treatment is not working or if she is experiencing any trouble, she must consult with the gynecologists. She can also do some exercises to stay active and healthy.

However, she should always consult a doctor before doing any exercise, especially for those who have experienced Asthma attacks in the past.

Effects of Asthma on Pregnancy

Poor Asthma management and difficult Asthma before pregnancy are associated with increased risk of hypertension during pregnancy, which can beget Preeclampsia. Studies have also shown that women with Asthma tend to undergo Caesarean sections more than others. It has also been observed that Asthma may restrict the growth of the fetus leading to low birth weight.

However, this is more due to poor Asthma control such as persistent breathing difficulty or poor lung function etc., than Asthma per se.

Effects of Pregnancy on Asthma

Certain physiological factors during pregnancy do affect Asthma. In difficult Asthma, control usually deteriorates between 24 and 36 weeks of pregnancy, mainly due to poor adherence to corticosteroids. This is why pregnant women with Asthma should be monitored closely irrespective of the severity of Asthma.

Breathlessness in Pregnancy

Breathlessness during pregnancy is common. In fact, even pregnant women with no Asthma symptoms may feel breathless at times. It reflects some normal physiological and anatomical changes during pregnancy. Even anxiety may precipitate breathlessness. This indicates that pregnant women with difficult Asthma may feel breathless, not just because of Asthma, but also because of normal changes during this period. However, new incidents of Asthma can also be a cause of breathlessness.

Respiratory Distress in Pregnant Women

Respiratory distress in pregnant women may not always be due to asthma. There may be a whole host of reasons that include Anxiety, Hyperventilation, chest infection, dysfunctional breathing, pneumonia, interstitial lung disease, thromboembolic disease, amniotic fluid embolism, pneumothorax, ischemic heart disease, arrhythmias, cardiomyopathy and a variety of endocrine, hematological and renal disorders.

Preventing Respiratory Distress During Pregnancy

Apart from avoiding Asthma triggers, pregnant women with Asthma or difficult Asthma need to strictly adhere to Asthma control. This indicates that they need to adhere to their corticosteroids religiously. However, before that, they also need to make sure that the corticosteroid is safe to be taken during pregnancy.

Asthma may or may not affect pregnancy. However, it is always a great idea to go for Asthma management. This will help women deal with complications related to Asthma during pregnancy.

Apart from that, always consult a doctor before going for any medication related to Asthma control, or actual treatment of Asthma.
