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 become a mother for the first time it is a completely new experience which may often leave you feeling exhausted and wondering whether all the things are being done right. First time motherhood is a beautiful as well as a harrowing experience at the same time. Although there are many important things to keep in mind, you can keep the responsibilities simple and streamlined in order to remember them. 

Some of these are mentioned below

Properly handling your baby   New mothers tend to be very careful anyway with their new born children. However, first time inexperience may cause harm to your baby inadvertently. Some of the things you need to be careful about while handling you baby are
Supporting and cradling the head and neck of your baby, especially while handling them is very important.
When you handle your baby, be careful enough to ensure that you don t shake or jerk them too hard. Always be very mindful of the fragility of your baby s body.
Keeping your hands clean every time before you handle your baby is extremely important.
Keep a hand sanitizer handy for this reason. Also, if you have to attend to your baby in the middle of house chores, such as kitchen work, wash your hands thoroughly with soap and wipe clean before handling your baby.
Perfecting your breast feeding technique is very important   One of the more important things to consider is getting attuned to your lactation cycles; either storing the excess milk for later or ensuring your baby is fed properly according to your cycles as well as his or her demand. Some of the points that need to be kept in mind are
It is important to know how to improve and make the best out of your breast milk through improved breast feeding techniques. Thus, visit a lactation consultant who can easily formulate a plan for you and optimize your breast feeding techniques.
Although breast milk is very important, some minerals can only be supplied by specialized formulas. The best way to balance between breast milk and formulas and you lactation consultant along with your doctor should be able to give you some pointers.
Your breasts will become sore after repeated feeding or suction. It is important to perform warm compress and heat massages to ensure that they don t hurt.
Soothing your baby   The only way your baby can communicate with you is via sounds such as crying and babbling. Thus soothing and comforting the baby is something which you may already do instinctively, but you may have to fine tune your technique slightly. Some of the things to keep in mind would be  
Swaying or swaddling you baby in a way that mimics the coziness of your womb
The baby can be kept entertained with sound and lights
Keep your baby warm, but not too warm depending on the season. Striking the correct balance is very critical.
Try to make the cleaning and changing process enjoyable for your baby by integrating play and fun into it.
Sleep for the mother and the baby   The priority at this point in time is to ensure your baby s growth and health. Thus, live by the principle that you sleep when your baby sleeps. Ensure that you adjust your routine to get the best results to minimize feeling tired all the time. New mothers tend to lose a lot of sleep and thus have interrupted circadian rhythms that affect their body. It is very important to maintain your mental composure and also be able to focus on your baby better.

First Time Mothers - Things You Should Take Care Of!

Growth is the most important aspect of childhood, one that distinguishes children from adults. Growth is affected by a number of diseases and growth failure is often the first sign of a serious disease. Unfortunately children with growth failure present very late when no help is possible. 

Why to worry?

Growth is the best marker of health and growth failure may be caused by a seious disease. Moreover children with short stature have lower self esteem. 

When to worry? 

Plot the height of your child in the growth chart and if it is below the lower limit visit a doctor. Alternatively if your child's height is less than the formula (Height = Age in years x 6 + 77 cm) it may be a cause of concern. Growth stops at the age of 14 years in girls and 16 years in boys. Hence the child should be reviewed latest by 10 years for girls and 12 years for boys. 

What causes growth failure? 

Growth failure can be due to a number of causes including poor nutrition, lack of physical activities and low genetic potential with parents being short. Short stature can also be caused by a number of diseases like thyroid problems, growth hormone deifiency and celiac disease (wheat allergy). 

How can I improve my child's growth?

Please encourage your child to play for atleast 1 hour a day. It is important to restrict screen time including television, computer, tablets and mobiles to less than an hour. Increased protein and calcium intake with more milk, pulses and vegetables also helps in improving growth. Growth hormone is produced during sleep. Sleeping for at least eight hours a day is therefore essential for a child to achieve good growth. 

What can be done if my child is very short? 

Please consut a doctor to identify the cause of short stature. Most conditions are readily treatable. Children with growth hormone deficiency respond dramatically to growth hormone. Growth hormone is also being used now in children with turner syndrome, familial short staure, small size at birth and kidney disease. 

Time is important- act now if your child is short.

What causes hearing loss? + How to ensure you can help it as you age

The partial or total inability to hear is known as hearing impairment or hearing loss. It can be present at birth, or develop later in life.

There are a number of factors, which may cause hearing loss

1. Age - Age is the biggest factor when it comes to the loss of hearing, and you may lose the ability to hear as you age. This condition is known as presbycusis. It becomes difficult to understand high-frequency sounds like that of a child or a woman when you get old.

2. Noise - When you are exposed to loud noises for a prolonged period of time, it damages your ears. This leads to loss of hearing. 5% of the total population of the world is affected by noise (the degree of suffering varies). It may be a result of continuous exposure to loud music or a sudden exposure to a loud noise like an explosion.

3. Hereditary disorders - Hearing disorder may be inherited by the dominant or recessive genes of parents in the child. 70-80% of these cases inherit from the recessive genes, whereas 20-25% inherit hearing loss from the dominant genes.

4. Trauma - Serious injuries of the head/ears may cause loss of hearing, which may be either temporary or permanent. When damage is caused to the brain, the brain fails to process the message conveyed by the ears. So even if the ears are totally functional, a person may face the problem in hearing.

5. Perinatal problems - The ototoxic effects on the fetus due to excess intake of alcohol during pregnancy lead to hearing the loss in about 64% of the infants born to alcoholic mothers.

Also, premature birth can be associated with hearing loss due to high risk of being exposed to noise in neonatal units.

Knowing about the causes of hearing loss can lead you a step closer to preventing this disorder as you age.

Here are some useful tips that can help prevent hearing loss:

1. Be more aware - You should be diligent and aware of the situations, which may risk your hearing ability and should try to avoid such situations as much as possible. Limit your exposure to sources of hazardous noises like firearms, firecrackers, concerts and clubs.

2. Take precautionary measures - If your occupation calls for working at an environment of loud noises, use earplugs or earmuffs to block out the excessive noise. Also, make sure that you work in a place where employers take all the necessary measures of noise control under the federal or state regulations.

3. Monitor your use of gadgets - Monitor and control the use of hearing devices, and try to reduce the use of headphones/ earphones as much as possible.



What causes hearing loss? + How to ensure you can help it as you age

You often get into this mess of losing part or whole of the tooth, and this is actually a nasty situation in several ways. You may get severe pain there, or the sharp edge of the broken tooth may cut the cheek and other areas of the skin in the mouth white chewing or biting. Besides, if left untreated the broken part may accumulate dirt and food particles and can later form serious infections in the gum too. It looks bad too when a front tooth is broken, and often leaves your inner mount with cuts and abrasions when the sharp edge of the broken tooth rips of skin inside the mouth as you chew.


The first aid part


There are several ways to manage the broken tooth, and the first steps of first aid after the incident are as follows:
-  To control the acute pain after the tooth break, you may take a painkiller like acetaminophen. This will soothe the pain, and make it much easier and bearable.
-  You must try sticking some sugar-less chewing gum on the tooth to prevent cutting inside the mouth. In case a gum is not available, you may try putting some simple wax in there.
-  Try gulping the food and chew less, or go on a liquid diet to avoid touch of much food with the broken tooth unless it gets the first treatment.


Filing and Bonding- the initial treatment
On going to the dentist based on the tooth break condition, you will be suggested various remedies. A tooth filing or bonding is the general remedy. If a small portion of the tooth is broken, then the tooth can be simply filed in case it is one of the rear teeth. The tooth will be chipped and filed to smoothen the cut edge so that it never again pokes the skin around. 
If the break is not small, then bonding is a good option. The dentist fills the rest of the tooth space with a resin or porcelain material to make it look whole and natural again, and this solves the problem both physically and cosmetically.


Crowning the tooth
If the tooth is damaged more than a root canalling may be needed, and thereafter a cap or crown will be worn over the broken teeth so that it gets a natural look and the hardness to chew. You may lose sensations permanently on the tooth if the root nerve is blocked during the process. Else you will have a cosmetically working tooth for a few years until the crown wears off and needs a re-crowning.

How To Repair Chipped Front Tooth In Child

Thumb or finger sucking is common in infants through the first year of their lives. A child usually turns to his thumb when he is tired, upset or bored.

A child younger than five years should not be pressured to stop thumb sucking. While majority of children give up such habits on their own before they enter school, about 15 percent of children continue thumb sucking past their fifth birthday. This is an age when teasing often starts, causing difficulties for children.

Apart from this, thumb sucking can also lead to dental problems. A child who is still sucking his thumb by age five, when permanent teeth start coming in, may develop an abnormal bite. In addition, prolonged thumb sucking can cause minor physical problems, such as chapped lips or cracked skin, calluses, or fingernail infections.

The effects of thumb sucking are usually reversible until the age of seven because children still have their deciduous (baby) teeth. If thumb sucking continues beyond that age, when the second teeth are erupting, permanent dental problems can occur.

There are various things you can do to help your child stop thumb sucking:

1. Reward your child and offer encouragement - for example, with a hug or praise to reinforce their decision to stop the habit.

2. Limit nagging - if children feel they are being nagged they will become defensive.

3. Mark their progress on a calendar - for example, place a star or a tick for each period (such as a day or week) that the child does not suck thumb or finger. Provide a special outing or a toy if the child gets through the period successfully.

4. Encourage bonding - for example, with a special toy.

5. Reminders - give the child a mitten to wear as a reminder not to suck, or place unpleasant tasting nail paint (available from chemists) on the fingers or thumb. Placing a band aid over the thumb at bedtime is another reminder.

6. Offer distractions - while a child is watching tv, have toys available for children to play with. Sit with the child during this time and give a cuddle to help them not to suck. In the car, have toys available to keep children occupied.

7. Talk to your pediatrician and your child's dentist, who may recommend appropriate treatment that prevents thumb sucking.
