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.

Hearing Loss In Children - Signs And Treatment Of It!

Mastitis is primarily an infection that occurs inside or on women's breasts within the first three months after pregnancy. Sometimes the infection can also affect non pregnant women where it is referred to as periductal mastitis.

What are the causes and symptoms of mastitis?
The most common reason behind such an occurrence is malfunctioning mammary ducts in pregnant women. Milk stasis or blocked milk ducts happen due to irregular feeding sessions, the baby's difficulty in sucking or not being able to attach optimally to the breast for feeding. The other plausible reason is bacterial infection that has somehow entered the ducts through a crack in the nipple area. Blocked milk ducts carry a lot of stagnant milk that provides the most suitable breeding ground for bacterial cultures. Steps must be taken so as not to pass on this bacterium to the baby who depends on breast milk almost entirely for nutrition.

1. It often manifests itself in the form of redness, swelling, pain, fever and exhaustion, resulting from inflammation of the breast tissues and mammary glands.
2. There is also a palpable warmth and tenderness of the breasts, accompanied by a general feeling of malaise.
3. Other common symptoms include lumpy formations, wedges, burning sensation especially during breast feeding.
4. Nipple discharge, body aches and relatively higher body temperatures might also occur in association.

You must consult with your doctor immediately after the appearance of similar symptoms; promptness is advisable when you are pregnant.

What problems does mastitis cause?
1. Most commonly affecting nursing and recent mothers, mastitis poses a pertinent problem in breastfeeding as it causes dysfunctional lactation.
2. Mastitis is therefore also as precarious for the new born baby who is left without its primary diet.
3. Doctors often recommend such mothers to continue breast feeding in spite of the disease, after prescribing some antibiotics which usually work in suppressing the infection after a maximum of 2 to 3 weeks.
4. The affected mothers usually feel too tired to take care of their child while suffering from this kind of infection.

Preventive measures
1. Avoid wearing tight clothes or undergarments.
2. Regularize breastfeeding schedules; do not stop before 6 months.
3. Encourage your baby to feed especially when you experience of build-up of milk.
