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?

When you have a newborn bundle of joy, no parent would be ready for constant crying bouts from the infant. However, for various reasons, even healthy, well-fed infants can be colicky.

What is it: although a mystery, a baby is said to be colicky if it cries for more than 3 hours a day for more than 3 days a week for more than 3 weeks at a stretch. The baby is completely healthy, and the symptoms start about 2 to 3 weeks of life in both breast-fed and bottle-fed babies. The baby usually has a red face from crying and could be pulling its legs towards its chest due to the abdominal discomfort.

Causes: though still not exactly established, some things that are believed to cause colic include:
1. The baby's digestive system that is growing and goes through spasms
2. Extreme sensitivity to noise and light in the surrounding environment
3. Accumulation of gas in the belly that is ingested with the milk (breast or bottles)
4. Hormones that are supposedly affecting the baby's moods

Treatment: as there is no specific cause identified, the treatment is also symptomatic and aims at soothing the baby's pain and discomfort.

1. Altered feeding: given that a baby's tummy is very small and is about the size of a fist, it makes sense to feed it small amounts at regular intervals than to give a full feed once in like 4 to 5 hours. The baby is sure to feel full with this and therefore the discomfort. Burping between the feed is also shown to help avoid feeling of fullness. If you are breast feeding, try to not let the baby doze off when feeding.

2. Anti-colic bottles: these bottles have a vent inside the bottle which will help reduce the accumulation of gas within the bottle. There are various brands available in the market, these could be a good solution if the baby is even partially bottle-fed.

3. Simethicone: this is an anti-flatulent, which again helps eliminate gas bubbles in the stomach and thereby provides relief to the infant. It can be given either by a dropper or a syringe.

4. Exercise: try bending the legs at the knee and holding it towards the baby's stomach, this can help ease the pain.

Remember that this is a very transient thing and usually disappears on its own by the 4th month, and the above measures are only to help the baby and the mother.

Colic Pain - How to Treat It

Stomach aches or abdominal pains are one of the most frequently reported health complaints faced by children. Children below the age of twelve are known to suffer from recurrent stomach pain. While pains such as these lead to momentary discomfiture, they also lay the path for graver worries if neglected for too long. Your child may feel sick and bunk school for two days; rest and home care can restore his or her health, but that in no way, is the best suited way of dealing with the situation. If tummy aches resurface over a certain period of time, parents should be cautious enough to look for the root cause and should try to eliminate it accordingly.

Widely noticed causes of stomach aches in children:

Unhygienic food can affect the child s digestive system.
Intolerance to a certain food item should not be overlooked.
Perpetual anxiety can make the tummy twist and turn.
Urinary Tract Infections can also lead to acute abdominal pain.
Serious factors such as gallstones or appendicitis could also be present. Immediate expert consultation is advised in such a case.
Caffeine and packaged soft drinks can be harmful.
Butter, ghee and other greasy products can trigger tummy aches.
Ways to treat tummy aches in children:

Keep children away from gas producing food items: Food that is hard to digest should be avoided. Lentil soup or dal should only be consumed in limited amounts to prevent the formation of gas. Don t let your child have too many nuts regularly.
Keep them hydrated: Fluid intake should be monitored. A child should drink at least six to seven glasses of water per day. Fruit juices or soups can also be given to them alongside main meals. This helps digestion.
Do not stack up food in one go: Eating a lot in one meal is a bad way of satisfying hunger. Have smaller meals in more numbers. Six to eight meals will keep your child full and will also eliminate chances of acid reflux which happens either due to an empty stomach or too much piling up of greasy food.
Timely check - up with the doctor: If tummy aches refuse to go away, take your child to a doctor for a thorough check- up. Administer medicines as prescribed by the physician.

Stomach Ache in Kids - 7 Causes Behind It!

Dyslexia is a neurological condition which makes learning a difficult process in children. Children suffering from dyslexia find themselves incapable of reading and learning as compared to their peers. Dyslexia occurs when the brain cannot process graphic symbols. This causes difficulty in recognizing, spelling and also decoding words. The effect of this condition varies from one person to another and is most often a lifelong condition. It can also vary as a result of different ages in people. However, a slower reading level is one common characteristic that is present in all dyslexic children.

Dyslexia is a strictly neurological condition that has little to do with a person s intelligence. It can also occur as a result of genetic conditions. Early detection of the condition can help in improvement before he or she reaches adolescence. A thorough evaluation process of the child will include the following aspects IQ level, language skills, ability of word recognition, phonological processing, automaticity skills, fluency skills, family history and also knowledge of vocabulary.

The most common symptoms of dyslexia include:

Trouble reading
Very slow progression to milestones such as walking, talking, crawling and learning to ride a bicycle.
Slow development of speech
Trouble with hand-eye coordination
A slow rate of learning when it comes to data
Problem with speech
Very poor concentration span
Children suffering from dyslexia are more prone to developing certain autoimmune diseases such as eczema and asthma.
Dyslexia is sometimes subdivided into a number of categories such as Surface Dyslexia, Rapid Deficit Dyslexia, Visual Dyslexia and Phonological Dyslexia.

There is no medical treatment for dyslexia and help generally includes assigning reading specialists, child psychologist, speech-language pathologists and child neuropsychologists.

Certain practices that you yourself follow when dealing with your dyslexic child are:

Praise your child from time to time
Remind your child that being dyslexic has nothing to do with intelligence levels
Mix with other parents who have dyslexic children and interact with them about ways and strategies to heighten the child s confidence level.
Deal with your child patiently.

Understanding Dyslexia - What All Should You Know

Upon reaching adolescence, children's bodies undergo several changes and so do their minds. It is then that their minds are most, as well as least impressionable. And the daunting question regarding the upbringing of an adolescent is how to treat their constantly changing behavior?

Here are some of the tantrums adolescents more commonly throw, and what should ideally be your approach to it:

Your child seems to hate you: It is very common for a phase of emotional exclusionism to prevail between 16-17 years of age approximately. And the worst thing you could do is heighten that emotion by returning the hatred. Make sure you're firm against any extremely unacceptable behavior, but at the same time, show them that you're there for them no matter what.
Electronic devices become the center of their attention: Whenever you want to have an earnest conversation with your children, their attention seems to be drawn solely to their phones and computers. They feel the need to be connected to their friends and all times. Ways to monitor that are by setting limit to the maximum hours spent on devices or making them pay their own bills, which will make them more responsible rather than splurging unnecessarily. Also, if your child is not entirely secluded from the family, it is probably best not to interfere all the time.
Ignoring the curfew: Your kids often stay out later than the set limit. But it is quite possible that your curfew is unreasonable when compared to other parents' curfew. Find out what the average time limit is; it may prevent your child from bearing a grudge against you. In case they still fail to respect your curfew, make sure you spill out to them what the consequences can be, like being grounded for a week. However, in certain cases, your child may be spending time doing nothing constructive, but away from home. There may be something else going on, find out what that is.
Being friends with the wrong people: Sometimes it might happen that you think some children do not have a good influence on your child, but you cannot say that directly because adolescents tend to get very defensive about their choice of friends. Unless the adolescent is doing something harmful with the friend, like using drugs, let him exercise his choice. Otherwise, don't hesitate from seeking professional help to counsel your child.
Being over-dramatic: Every emotion is heightened in your child and you cannot tell them that what they are whining or being overjoyed about are trivial, because that's their prime focus then. Let them realize on their own how irrational they sound or else you may risk spoiling your relation with them.

Behavioral Problems in Adolescents

3 lesser known facts about breastfeeding

Breastfeeding is advocated to be the only best thing for a newborn. But while it is the most natural thing to do, it isn't an easy process. It is challenging and full of surprises. Researches throw up facts that surprise all. For example: breastfeeding is like a shield against breast cancer. 
Here are 3 such lesser known facts:

1. The milk contents - ever wondered what your baby thinks of the taste of your breast milk. Well, the fact is that your breast milk is tailor-made for your baby. From the taste to its benefits, it is a full course meal. When the feeding begins, the milk is watery. This is to quench the baby's thirst. Then the consistency thickens and the milk becomes higher in fat content. This meets your baby's electrolyte needs as well as energy requirement. Want to know something more amazing? through the day, your breasts milk's properties keep changing. By evening, it has higher sedating properties and helps the baby's body meet nutritional demands. This should explain that satisfied smile babies have when they sleep right after their feeds.
2. Variation in milk production - it is okay and natural if you feel you are lopsided. Many breastfeeding mothers feel that one breast is heavier than the other since it produces more milk. This is possible and happens a lot. Our body is not perfectly symmetrical between left and right. This applies to breasts as well and shouldn't be worried about. Because of this, milk production can also vary between both the breasts.
3. It causes weightloss - some women are known to lose their pregnancy weight by breastfeeding. Yes, this is also a lesser known fact. Breast milk happens to be a high calorie food which the baby literally sucks off the mother's body. This leads to shrinking of the mother's body.
