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?

Few things in life take longer than habits to be inculcated and eventually to die out. Every parent tries in his or her way to teach the child certain healthy habits, those that they wish would be followed long enough to be internalized by them. Certain healthy habits that every child should follow are:

1. Include a lot of vegetables in the diet: There is an array of vegetables available in the market, which is replete with rich nutritional values. Though children are generally averse to the idea of eating vegetables, it is your duty to inculcate in them the habit of eating vegetables and constantly remind them of their rich nutritional benefits.

2. Never skip breakfast: Breakfast is the most important meal of the day and is often the most ignored. Most children have the propensity to skip breakfast if they are late and generally they are seldom reprimanded by their parents. As a parent, you must make it a point not to take this lightly and severely insist on a healthy breakfast every morning.

3. Indulge in physical activities: With the advent and easy access of technology, going out to play in has become a distant reality, one that is never explored. However, it goes without saying that nothing can substitute the physical and mental benefits that a physical activity entails. It not only keeps the body of your child fit but also helps in keeping the mind fresh.

4. Read daily: Few things in life can be as rewarding and fulfilling as reading a book. However the habit does not come easy and as a parent it is your responsibility to induce in them this. Try to make your child read a few pages everyday till they take it up themselves out of their volition.

5. Drink water and skip the soda: The many flavored sodas, which are available serve as a more palatable alternative to the drab water for the children. Though the choice may seem convenient, it must be snipped off right from the beginning. Sodas are packed with harmful preservatives and should be duly avoided by children. Instead, they must choose the bottle of water to quench the thirst.

5 Healthy Habits That Every Child Should Follow

Spitting up, refusing to try new foods and occasionally turning up their noses at feeding times, is normal but consistently refusing food and water, vomiting and allergies may indicate an underlying medical condition that requires attention. Common feeding problems that affect infants include sucking, prolonged chewing without swallowing, holding food in their mouth and grabbing food. Infants who are unable to close their mouths in order to keep food inside may also be said to be suffering from feeding problems.

Feeding problems could be triggered by medical conditions like a cleft palate, premature birth, respiratory problems, low birth weight etc. or by non-medical reasons such as the child s feeling of being unloved or stressed. Symptoms of feeding problems vary from infant to infant. However, some of the common symptoms exhibited are:

Problems with chewing

Excessive drooling

Refusing to eat foods or drink liquids

Long feeding times

Coughing or gagging while feeding

Difficulty with breast or bottle feeding

Nasal stuffiness while eating

Poor weight gain

Recurring respiratory infections

Vomiting or excessive spitting up of food

Arching the back while feeding

Disinterest in feeding

Though feeding problems are minor in most cases, it is important to consult a doctor if this behaviour continues over a period of time. This is because the child may be suffering from an underlying medical condition or could be at an increased risk of suffering from dehydration, aspiration and lung problems. It could also lead to delayed physical and mental development, speech problems and cognitive issues.

Feeding problems are addressed in many different ways. The first step to dealing with feeding problems is to change the texture and temperature of food being given to the baby. In addition, try changing the posture of the baby while feeding.

In some cases, mouth exercises may be needed to strengthen the mouth muscles. Chewing exercises and tongue movement may also help reduce feeding problems.

Encourage your infant to try different types of food by including different textures in their daily meals. Alternating food textures and liquids can make it easier for the infant to swallow the food. Do not force your child to eat in a hurry but let him or her take their own time.

In cases where the infant is not gaining weight, the doctor may suggest nutritional changes and a specific diet to help gain weight. In emergency cases, hospitalisation may also be required and your baby may be given a feeding tube to ensure he or she receives adequate nutrition.

Medication to relieve fever
Antibiotics to prevent or treat accompanying bacterial infections
Vitamin A supplements to reduce the severity of measles symptoms
Pain relievers to deal with muscle pains
