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?

It is no longer so surprising to read about alarming air pollution levels in our cities. On more than one occasion, these levels have risen above the danger levels. For some people, this may simply create an annoying fog that makes it difficult to see. For others, it can cause serious health issues. Air pollution is one of the most common reasons for the growing instances of asthma and allergies. Children are most susceptible to such diseases caused by air pollution.

Asthma and Allergies
Asthma can affect children even before their fifth birthday and the condition is characterized by breathlessness caused by a constriction of the airways. While the root cause of asthma is unknown, it is usually seen that asthmatic patients are more sensitive to others to particles in the air such as pollutants, dander, dust, smoke etc. Thus, the airways construct as a reaction to these allergens. Changes in the weather, a sudden cold draft or the flu can also aggravate asthma.

Can you Protect Your Children from Asthma?
Wheezing, panting, finding it difficult to breathe and a persistent cough are some of the signs of asthma. If you notice these symptoms, you must consult a doctor immediately. At home, here are a few things you could do.

Avoid exposing your children to smoke: Do not smoke around your children or allow others to smoke around them. If you cannot give up the habit, wear a smoking jacket when you smoke and take this off before you play with your children. When you ll go out, drive with the windows up so that your child does not inhale exhaust smoke. Set your air conditioner to circulate air within the car itself.
Dust often: Try and keep your home as dust free as possible. Use a wet cloth to clean so that the dust does not fly in the air. Wash all your bed linen once a week. Carpets and rugs should be vacuumed regularly or dusted outside. It may also be a good idea to invest in dust mite impermeable covers for your child s mattress and pillows.
Keep your Pets clean: If you share your home with pets, bathe them once a week and brush them daily. Do not let them climb on to the furniture or your beds. Also, avoid having their toys lie on your beds.
Wear a face mask: Try and time your child s outdoor activities when the pollution levels are low. Buy yourself and your child a face mask that will filter the air they breathe in. These should be worn whenever they play outdoors.
These simple steps could help your child be healthier and can prevent asthma and other such allergic reactions.

Sudden Infant Death Syndrome (SID) refers to the unexplained and sudden death of a seemingly hale and hearty baby. This condition tends to occur when the baby is asleep and that's why it's also known as crib death. Although the reason for the condition is still not known, many experts have attributed the cause of the condition to abnormal development in the parts of the baby's brain that oversees breathing and awakening from sleep. Nonetheless, there are ways that can prevent the problem from occurring and which are:

Always place your baby on the back to sleep

Sleeping on the back is the safest position that your baby should be in, whenever he or she sleeps. You shouldn't let your child sleep on the sides as he or she can roll onto the stomach, and may hamper the breathing process. You can place your baby on the stomach when he or she is awake.

Place your baby on a firm surface to sleep sans of any objects

It's best to place your baby on a firm mattress to sleep while avoiding thick and feather padding like a thick comforter. At the same time, objects like toys, stuffed animals or pillows should be removed from the crib as they may get in the way of your child's breathing by pressing on his or her face.

Make sure your baby doesn't become very hot

For keeping your baby warm during sleep, it's best to opt for sleep clothing or blanket made of light material so that it doesn't make him or her feel very hot. If using a blanket, it should be placed loosely over the baby and one should also remember to not cover the baby's head during sleep.

Use a pacifier

Research suggests that the use of the pacifier can reduce a baby's chance of dying from SIDS. This is because the pacifier helps in preventing the baby from rolling over onto his or her stomach during sleep. At the same time, it's also believed that the instrument helps in keeping the baby's tongue positioned in a manner that keeps his or her airways open.

Breastfeed your baby

Breastfeeding your baby for a minimum of 6 months can help in preventing the occurrence of SIDS. Several studies have revealed this beneficial aspect of breastfeeding.



5 Ways to prevent Sudden Infant Death Syndrome (SID)

Tonsillitis is an affliction that plagues a fair share of people. Located at the back of your throat, tonsils are essentially two small glands, which contain white blood cells to defend your body against infection. However, on account of germ attacks, sometimes the tonsils get infected and this results in the swelling of the tonsil glands, which in turn causes sore throat and aligned maladies. 

Tonsillitis may be cured through surgical procedures. However, an isolated case of the inflammation of the tonsils need not warrant a surgery. Tonsillectomy or the surgical method of curing tonsillitis is only recommended for extreme cases of tonsillitis. Only the frequent sufferers of tonsillitis take recourse to tonsillectomy for a durable and effective solution. Surgeries are only done on those who have had at least seven bouts of strep throats within a span of a year. 

Tonsillectomies essentially involve surgical removal of the tonsils either using a scalpel or burning the tissues in the tonsils with the use of ultrasound vibrations. Usually performed under anesthesia, it is a fairly painless and a non-hazardous procedure. Tonsillectomies generally last for about an hour. However, the recovery period sometimes entail a few physical discomforts. Sore throat, difficulty in swallowing, pain in the jaws and ears are common symptoms of post tonsillectomy conditions. While there are palliative medicines available in the markets, adequate rest and proper diet speeds up the recovery. 

Tonsillectomy generally leaves no side effects and the success rate of this surgery is quite heartening. Tonsillectomy has also known to cure several other associated health problems in the likes of breathing troubles, sleep apnea, bleeding of the tonsil glands or cancerous developments in the tonsil glands. That aside, tonsillectomy is only performed on acute cases of tonsillitis and often regarded as the lender of last resort when medicines stop according any relief to the patient.

When to go for a Tonsil Surgery?

A mother s milk is said to be the most nutritious food for a new born baby. It contains the perfect balance of carbohydrates, fats, proteins, vitamins and minerals needed for your baby and changes to keep up with your baby s growing needs. However, the benefits of breastfeeding extend way beyond nutritional value. Breastfeeding is beneficial for both you and your baby. Ideally, a baby should be breastfed for at least the first six months. 

Here are 5 major benefits of breastfeeding.

Stronger immunity: Mother s milk is rich in antibodies and a number of unique compounds that help the newborn child s body fight bacterial and viral infections. No other form of baby food is as rich in these antibodies. Babies who have been breastfed have a lower risk of suffering from ailments such as ear infection, stomach upsets and respiratory problems. The first milk expressed by a woman s breasts after giving birth is known as colostrums. This milk coats the baby s digestive system and prevents the growth of harmful bacteria.
Fewer allergies: Breast milk is easier to digest than formula or cow s milk. This protects the gastrointestinal passages from inflammation and prevents undigested food from triggering allergic reactions. Being breastfed can also reduce the number of allergies a child may suffer from in their later years.
Healthy body weight: Breastfeeding makes a child less likely to suffer from obesity in their later childhood and adult years. This is because breast milk contains less insulin and more hormones as compared to formula. This helps regulate fat absorption. On an average, babied fed on formula put on weight quickly and are more likely to overeat in their later years.
Stronger bones: Breastfeeding is beneficial for both the child and the mother. When a woman is breastfeeding her child, her body s ability to absorb calcium increases. This helps increase bone density, especially as pregnancy can make bones weak.
Builds a strong mother-child bond: After 9 months of carrying a child to term, giving birth may lead to post partum depression and a mother may feel the connection between her and the child severed. Breastfeeding helps nurture this connection and provides emotional relief to both the mother and child. For the mother, this experience releases hormones that reduce stress and relax the body. For the baby, close physical contact is very important and this process provides the perfect opportunity to do so.
