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.

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?

The mere thought of biting into a chilled watermelon or sipping chilled watermelon juice during summer is a refreshing thought. What many do not readily realise is that not just they are not just a refresher, but they are also loaded with multiple health benefits. Another surprising fact is that they have been in use since 5000 years ago and are referred to in ancient literature. There are about 300 varieties and are easily available during summer.

Many may think that watermelon is loaded with water. However, there are also multiple compounds including vitamins and minerals; vitamins C, A, B1, B5, and B6; minerals like potassium and magnesium, and compounds like carotenoids and lycopene. These have multiple benefits on the health and so watermelon can be consumed without any second thought in abundance.

Read on to know some of the wonders of this melon.

Hydration: One of the best remedies to avoid the ill effects of summer is to improve hydration levels, and there could be no better way to do this than with watermelon (eat it or drink it!) It is 92% water, and therefore leaves you refreshed and rejuvenated.
Heart health: Lycopene helps reduce cholesterol, reduce thickening of artery walls, and reduces oxidative stress. The various minerals and vitamins also add to the heart health qualities of watermelon. The citrulline in it also increases nitric oxide level in the body, which expands or dilates blood vessels and improves blood pressure.
Anti-inflammatory benefits: The lycopene and vitamin C reduce the levels of C-reactive protein which are responsible for inflammation. The antioxidant levels also lower inflammation, thereby reducing the onset of degenerative diseases like Alzheimer s.
Eye health: Watermelons, through their anti-inflammatory effects, reduce the onset of age-related macular degeneration. Those who already have it can also see the delayed progression of the condition, thereby prolonging vision loss.
Muscle soreness: Those who have muscle soreness should reach out for a slice of watermelon to get instant relief from this soreness. Watermelon also improves exercise endurance and performance, and the added benefit on the heart also improves exercise tolerance.
Skin and hair benefits: These benefits come from multiple sources in the melon. The vitamin A helps improve skin regeneration, vitamin C helps collagen formation and improved skin tone. Lycopene and beta-carotene help control the damage caused by sun exposure and pigmentation.
Digestive benefits: The very nature of watermelon almost completely water and high fibre directly benefits the stomach. It cleanses the stomach and promotes bowel movement. Not just the red portion, even the rind and seeds are beneficial as there is a lot of citrulline and chlorophyll which are also healthy.

Watermelon - One Fruit, Many Benefits!

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.
