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?

Diabetes is a chronic metabolic disorder that results in higher level of blood sugar in the body. It is assuming epidemic proportions and India has become the new diabetic capital with more than 50 million diabetic people. The main problem with diabetes is that it does not completely go away and there is a whole myriad of issues that it brings along with it. Heart attack, stroke, eyesight problems, delayed wound healing, nerve damage and impotence. Therefore, diabetes and by that we mainly mean blood sugar level has to be managed so that there is a delay in onset of the associated conditions and/or reduced in severity.

Ayurveda refers to diabetes as Prameha (excessive urination) and Madhumeha (sugary urine) and has identified close to 20 forms of the disease. According to Ayurvedic belief, each disease is caused due to imbalance in kapha, pitta, and vata doshas and diabetes is caused by all these, predominantly by kapha. With any stream of medicine, management of diabetes involves two tracks   one is lifestyle changes and the second is medications.

Lifestyle changes include the following:

    Diet: Reduce the amount of rice, sugar, potato, sweet fruits, maida, deep fried foods, and red meat. Protein-rich foods like lentils, soya, green leafy vegetables and fish should be increased. Diet plan should change to small, frequent meals instead of binge eating.

    Exercise: Include 30 minutes of regular exercise into your daily routine if you have a diabetic predisposition.

    Others: Avoid smoking and alcohol, ensure sufficient sleep, avoid sleeping during day time, improved foot and eye care, periodically check sugar levels and manage stress levels.

Medication

Ayurveda has a whole lot of home remedies which have proven to be very effective against diabetes:

    Jambhul: Eugenia Jambolana whether eaten raw or juice extract has been shown to have beneficial effects in managing sugar levels and cholesterol.

    Gymnema sylvestre: Used to manage diabetes for over 2000 years, it reduces sugar cravings and is being touted as the future for diabetes treatment.

    Bitter gourd (Momordica charantia): It has 3 components that give it strong antidiabetic properties. The charantin reduces blood sugar levels; the polypeptide has insulin-like effects; and lectin that again has hypoglycemic effects.

    Bel (Aegle marmelos): Also known as wood apple, leaves of the plant are shown to have antidiabetic properties. 5 to 10 leaves can be chewed on a daily basis to help control blood sugar levels.

    Fenugreek (Trigonella foenum graecum): Consuming 10 g of fenugreek seeds soaked in water increases the amount of insulin produced, thereby increasing sugar breakdown.

    Neem: Chewing about 4 to 5 leaves in the morning on an empty stomach helps to control blood sugar levels. Alternately, neem leaves powder is available which can be dissolved in water and consumed.

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

Sometimes children suffer from conditions where their feet may not be in proper shape or size, something that can affect their posture. Most of the times the disorders get corrected themselves as children grow up, but there can be situations where medical attention is required. These conditions can be normal variations in the anatomy as well which don't essentially require treatment. Some of the common orthopedic disorders found in children include:

1. Flatfeet

While most babies are born with flat feet which develop arches as they grow, in some case the arches remain underdeveloped even after they grow older. Their feet may turn inwards while they walk due to their flat nature. There is no inherent problem in this condition unless it becomes painful. Doctors may recommend special footwear with arches inserted for support to reduce the pain.

2. Toe Walking

Toe walking is not a disorder while your child is just learning to walk. Toddlers who continue to walk on their toes after the age of 3 may require medical attention. Toe walking on one leg or persistent toe walking can be due to other medical conditions like muscle weakness, cerebral palsy or autism. It is advisable to take your child to a therapist for casting the foot and ankle which can help stretch the muscles.

3. Pigeon Toes

In toeing or pigeon toeing is common among babies when they are first learning to walk. Sometimes children above 3 years walk with their toes inwards which can be due to femoral anteversion. This happens when upper part of the leg bends more than it naturally should, causing inward rotation of the feet. Specially designed shoes and braces can help to correct this condition. Usually, the condition corrects on its own with age and does not interfere with sport activities which involve running.

4. Knock-Knees

It is a common tendency among children aged between 3 and 6 to develop knock-knees (genu valgum), since their bodies go through natural shift in alignment. Usually, treatment is not required as the legs straighten out eventually. Knock knees on one side or persistent knock knees may require medical attention. Children with this disorder may suffer from pain hence in some cases surgery is recommended after the age of 10.


Common Orthopedic Disorders In Children

Iron is an essential nutrient and mineral that is required by adults and children alike. Iron helps move oxygen from the lungs to the rest of the body and helps muscles store and use oxygen. It is especially important for children because it aids development and prevents anaemia. Untreated iron deficiency in children can cause physical and mental delays. It can lead to less healthy red blood cells in the child's blood stream which will cause a delay in the growth of physical and mental faculties.

Risk factors for iron deficiency in children

Infants and children at highest risk of iron deficiency include:

Babies who are born prematurely or have a low birth weight
Babies who drink cow's milk before age 1
Breast-fed babies who aren't given complementary foods containing iron after age 6 months
Babies who drink formula that isn't fortified with iron
Children ages 1 to 5 who drink more than 24 ounces (710 milliliters) of cow's milk, goat's milk or soy milk a day
Children who have certain health conditions, such as chronic infections or restricted diets
Children ages 1 to 5 who have been exposed to lead
Adolescent girls also are at higher risk of iron deficiency because their bodies lose iron during menstruation.
Symptoms of iron deficiency anaemia

The signs and symptoms of iron deficiency anaemia in children may include:

Pale skin
Fatigue or weakness
Slow cognitive and social development
Inflammation of the tongue
Difficulty maintaining body temperature
Increased likelihood of infections
Unusual cravings for non-nutritive substances, such as ice, dirt or pure starch
Prevent iron deficiency in children

Take steps to prevent iron deficiency in your child by paying attention to his or her diet. For example:

Breast-feed or use iron-fortified formula. Breast-feeding until your child is age 1 is recommended. If you don't breast-feed, use iron-fortified infant formula.
Encourage a balanced diet. When you begin serving your baby solids, typically between ages 4 months and 6 months, feed him or her foods with added iron, such as iron-fortified baby cereal. For older children, good sources of iron include red meat, chicken, fish, beans and dark green leafy vegetables. Between ages 1 and 5, don't allow your child to drink more than 24 ounces (710 milliliters) of milk a day.
Enhance absorption. Vitamin C helps promote the absorption of dietary iron. You can help your child absorb iron by offering foods rich in vitamin C, such as melon, strawberries, kiwi, broccoli, tomatoes and potatoes.
Consider iron supplements. If your baby was born prematurely or with a low birth weight or you're breast-feeding a baby older than 4 months and he or she isn't eating two or more servings a day of iron-rich foods, talk to your child's doctor about oral iron supplements.
Make sure that you watch out for the tell tale signs of iron deficiency and take the necessary precautions to avoid the same.
