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?

Tonsillitis, in the easiest terms, is the swelling of tonsils in our throat that is accompanied by symptoms like throat pain, difficulty in swallowing/ drinking, altered voice and fever etc.

As in the case of most infections, the occurrence of tonsillitis is more common in children due to relatively lower immunity and habits that invite infections. Let's take a look at the first line of defence when you have a cranky child with swollen tonsils.

1. Make your child gargle with salty warm water: This treatment is most helpful in any infection in the mouth. Add half teaspoonful of salt to a glass of warm water and make the child gargle with the mixture as many times in the day as possible (to a maximum of 5 times). Continue till the condition prevails.

Make sure the child spits out the water and not drinks it.

2. Antibiotics: Consult the ent specialist and have the antibiotics if it is a bacterial cause as per the doctor. Take the alternative treatment prescribed in case of other causes. The entire course of medication should be completed even if the kid gets better sooner to eliminate all traces of bacteria.

3. Painkiller/numbing lozenges: Painkillers that are prescribed by the doctor can be given to ease the pain. Same is the case with lozenges but care should be taken that he/she should not have too many of these.

4. Allow him/her to take rest: It does help in a betterment of the condition!

5. Give warm (not hot) soothing food: Soup, ginger honey mixture, ginger tea can help soothe the inflamed tonsils in most cases. The condition, more often than not, gets better within 7-10 days.


Best Ways to Deal With Tonsillitis in Kids

4 Foods That Strengthen Your Child’s Teeth

Kids have a mind of their own when it comes to food. The unhealthier it is, the more they tend to like it. Most taste driven or sweet foods are harmful for your child’s oral hygiene. However not all foods that your children like to eat are as bad for their oral health, some even help strengthen their teeth.

Here are 4 foods that your children can have for healthy teeth and gums.

1) Sugarless Gum - It helps loosen plaque and increase the number of natural antibodies in the mouth. It also keeps the gums hydrated. While too much of anything is not good, these gums are good once in a while.

2)  Crispy Vegetables  - These might not be popular with children but can be made yummy with interesting dips to go with them. Raw carrots, celery, cauliflower, and green beans are chewing foods which clean the child's teeth and gums.

3) Natural Sugar - Sugar from milk, yoghurt and cheese are rich in vitamin D, phosphate and calcium. When consumed, they raise the pH level of the mouth which lowers the level of acids, hence reducing risk of tooth decay.

4) Vitamin C Rich Foods - Fruits like oranges, kiwis, strawberries, papayas and limes help kill bacteria that can cause gingivitis. They also aid a good supply of collagen in the child's gums. However, parents need to remember that one can eat citrus foods only after thirty minutes from brushing their teeth. This is because the citric acid in these foods can weaken the tooth enamel temporarily.

4 Foods That Strengthen Your Child’s Teeth

There are few things I hear over and over again from students
1.  How they are studying for so many in a day
2.  How they do not have even time for anything else in their life due to study pressure
3. How they are sleep deprived
4. How much they are stressed
5. And finally, after all the sacrifices and hard work, their exam performance is not what they expect.

Here are few tips to study smart, improve your grades and yet have a life!
We all know that 2 hours of focused study will be much more productive than 4 hours of distracted study. And, the good news is that concentration is a mental skill that you can develop and improve. There are two ways to improve your concentration:

A. First, work on raising your brain's natural ability to concentrate or in other words, learn to increase your attention span.
B. Second, adjust the environment around you to make concentrating easier.

Improving your concentration takes a little time and effort, but it is worth it. In my personal experience with students, I have seen noticeable improvement in relatively short time.

A. Ideas for daily concentration boosting habits include

1. Mindfulness meditation: Many studies confirm that 20 minutes of meditation or more per day improves concentration and attention span. Mindfulness meditation, where one focuses on one's breathing,  is one of the simplest way of meditation. Start with ten minutes in the morning and ten minutes before bed. To begin with you may try a guided meditation. One can easily find audios for guided meditation online.

2. Proper sleep: I am sorry to say this. Pulling all nighters will not help with your grade. Unless you are getting sufficient restful sleep, you are not going to be as mentally focused as you could be to study as well as answer questions in exams.

3.  Food for your Brain: The more you use certain skills, the more they are reinforced in the brain. So it makes sense that playing concentration games and games that require you to focus will improve your concentration ability. You need to be consistent in this. Play for about 10 to 20 minutes each day. Have fun, and get the benefits but remember not to spend more than 20 minutes a day. Your goal is to improve your concentration and not just keep scoring higher in the game! Try Lumosity and use only free version this will help you restrict your daily play time to 20 minutes and have maximum benefit.

4. Eat healthier: Your brain needs the proper nutrients to allow you to focus. Eat more vegetables and fruits and avoid consumption of junk food as much as possible. Instead you could keep some nuts such as walnuts, almond or peanuts as in between munches. Lot of research has now proven that sugar is very harmful for our health. Reduce sugar and refined white flour in your diet as much as you could.  

5. Exercise: It is helpful in both reducing stress and increasing energy and focus. At least 20 minutes a day would go a long way. Going for a short jog of 20 minutes will make next 4 to 5 hours of study very efficient.

B. Optimize your mental state & environment

In addition to building the habits described above into your daily routine; also adjust your environment and your current mental state to improve your concentration when studying.

1. Create a study space: Your brain loves routine. Create a place where all you do is study. An obvious choice is a secluded desk of some kind, but the trick is to make sure you only study in that spot. Studying in bed is a bad habit, for example, because your body is trained to want to sleep once you get into bed.

2. Remove distractions: Turn off the ringer on your phone and take other steps to prevent interruptions. Don't study with the television on or with radio playing. Some studies have shown that soft instrumental music (no vocals) can help improve your concentration.

3. Reduce background noises: If you have to study or work in an environment where it is too loud (classroom or open space) or too quiet (such as at home or at a library) you can get easily distracted by outside influences. With the right amount of background noise you can actually block out distractions and enhance your creative thinking.

4. Use timer: Set a time limit when you need to study new material. For example, let's say you want to read one chapter in a book (and remember it). Decide in advance that you can have 45 minutes to read the chapter, and 15 minutes to review it. Set a timer to keep yourself honest, then pace yourself to keep within the allotted time.

5. Stay motivated: If you see studying as burden, it's hard to concentrate. One way to stay motivated is to set up a reward system. Tell yourself you have to earn that hour of watching your favorite show later in the evening by first completing 2-3 hours of intense studying.
That way, even if the material is dry, you have the reward to look forward to.

6. Take breaks: Take a break every two hours. You mental energy will begin to decline after a long period of study. So every two hours or so, take a ten minute break. Walk around, eat a light snack, or just stare at the wall to relax your mind.

Concentrating is the first step to learning anything new. It only makes sense that if you improve your concentration, your memory will improve also.

How an expert can help?
If you want to get individualized expert opinion about how you are studying currently and what ways you can improve; you can always consult the expert. Once he/she knows what your current study methods are, they will be able to give you specific tips to improve upon. Most likely once you incorporate those tips you will be spending less time studying and your grades will improve. That's what is studying smarter and not harder means!!
