A baby should be breastfeed for at least the first few months after birth. Breastfeeding has a number of benefits for both the mother and child. Apart from being the best source of nutrition for the baby, it also helps the mother and child bond.

Here are a few benefits of breastfeeding your baby.

1. Nutrition: No formula can be compared to the nutrition provided by a mother’s milk. The first milk produced by a mother’s breasts is known as colostrum which is rich in antibodies and proteins. Breast milk is made up of the perfect mix of proteins, vitamins and essential fats. It is also easier to digest as compared to formula feeds.
2. Immunity boost: A mother’s milk is rich in antibodies and helps strengthen the newborn child’s immunity. These antibodies also help lower the baby’s risk of developing asthma or allergies later in life. Babies that are breastfed are also said to have a lower risk of suffering from ear infections, respiratory problems and diarrhoea. It also plays an important role in lowering chances of sudden infant death syndrome. Breastfeeding is also said to protect babies from certain types of cancer in infancy and later stages,
3. Bonding: While being breastfed, a baby is held close to the mother and has skin to skin contact. This makes the baby feel secure and helps him or her to bond with the mother. For the mother, this process can also help fight postpartum depression and help reconnect with the baby.
4. Healthy weight: Babies who are breastfed are said to be less likely to develop obesity. This is because breast milk has lower levels of insulin as compared to formula and babies who are breastfed have higher level of appetite and fat regulating hormone called leptin. As they grow, these babies put on a healthy amount of weight, but refrain from overeating and have healthier eating patterns. This helps maintain a healthy BMI and prevents diseases like diabetes etc.
5. Boosts intelligence: Studies show that babies who were breastfed for the first six months have a higher IQ than those who were not. Thus, breastfeeding is said to play a significant role in cognitive development. There are two main reasons for this. Firstly, breast milk is said to fatty acids that are not available in formulas, Secondly, the emotional bonding between mother and child is also said to contribute towards boosting IQ levels.

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

1. 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.
2. 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

1. Total Lung Capacity – the amount of air present in the lungs after breathing in deeply
2. Forced Vital Capacity – the amount of air that can be exhaled after breathing in deeply
3. Minute Volume – the amount of air exhaled per minute
4. Vital Capacity – the total volume of air that can be breathed out after inhaling as much as possible
5. Tidal Volume – the amount of air inhaled or exhaled when breathing normally
6. Maximum voluntary ventilation – the amount of air that can be inhaled and exhaled in one minute
7. Functional Residual Capacity – the amount of air that remains in the lungs when breathing normally
8. Forced Expiratory Flow – the flow or volume of air during an exhalation
9. 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. In case you have a concern or query you can always consult an expert & get answers to your questions!
