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?

Asthma is the most common chronic condition for women in pregnancy. While Asthma control can affect pregnancy, pregnancy too can affect Asthma. Yet while pregnancy does not beget Asthma, neither does it abate.

Nevertheless, Asthma management during pregnancy is very important. Improper Asthma management, especially in difficult Asthma, during pregnancy may imperil both the mother and the child.

Along with taking the right medications, Asthma patients also need to avoid exposure to Asthma triggers.

Avoiding Asthma Triggers

Asthma triggers may be different for different people. In general, one or a few of the following act as Asthma triggers:

Allergens like pollen, dust mite etc.

Smoking

Certain exercises

Certain occupational exposure

Pollution

Certain drugs like  blockers, aspirin etc.

Alcohol, dairy products, orange juice, peanuts etc.

Additives like tartrazine, monosodium glutamate etc.

Certain medical conditions like gastric reflux, rhinitis etc.

Apart from avoiding these Asthma triggers, she would also need to follow the instructions of her gynecologists. She should always be concerned that if the treatment is not working or if she is experiencing any trouble, she must consult with the gynecologists. She can also do some exercises to stay active and healthy.

However, she should always consult a doctor before doing any exercise, especially for those who have experienced Asthma attacks in the past.

Effects of Asthma on Pregnancy

Poor Asthma management and difficult Asthma before pregnancy are associated with increased risk of hypertension during pregnancy, which can beget Preeclampsia. Studies have also shown that women with Asthma tend to undergo Caesarean sections more than others. It has also been observed that Asthma may restrict the growth of the fetus leading to low birth weight.

However, this is more due to poor Asthma control such as persistent breathing difficulty or poor lung function etc., than Asthma per se.

Effects of Pregnancy on Asthma

Certain physiological factors during pregnancy do affect Asthma. In difficult Asthma, control usually deteriorates between 24 and 36 weeks of pregnancy, mainly due to poor adherence to corticosteroids. This is why pregnant women with Asthma should be monitored closely irrespective of the severity of Asthma.

Breathlessness in Pregnancy

Breathlessness during pregnancy is common. In fact, even pregnant women with no Asthma symptoms may feel breathless at times. It reflects some normal physiological and anatomical changes during pregnancy. Even anxiety may precipitate breathlessness. This indicates that pregnant women with difficult Asthma may feel breathless, not just because of Asthma, but also because of normal changes during this period. However, new incidents of Asthma can also be a cause of breathlessness.

Respiratory Distress in Pregnant Women

Respiratory distress in pregnant women may not always be due to asthma. There may be a whole host of reasons that include Anxiety, Hyperventilation, chest infection, dysfunctional breathing, pneumonia, interstitial lung disease, thromboembolic disease, amniotic fluid embolism, pneumothorax, ischemic heart disease, arrhythmias, cardiomyopathy and a variety of endocrine, hematological and renal disorders.

Preventing Respiratory Distress During Pregnancy

Apart from avoiding Asthma triggers, pregnant women with Asthma or difficult Asthma need to strictly adhere to Asthma control. This indicates that they need to adhere to their corticosteroids religiously. However, before that, they also need to make sure that the corticosteroid is safe to be taken during pregnancy.

Asthma may or may not affect pregnancy. However, it is always a great idea to go for Asthma management. This will help women deal with complications related to Asthma during pregnancy.

Apart from that, always consult a doctor before going for any medication related to Asthma control, or actual treatment of Asthma.

Difficult Asthma - All You Should Know!

The festival of Diwali is greeted with great pomp and splendour and along with the regular festivities, the pollution levels in the air also rise due to the ritual of bursting fire crackers. In an analysis, the rise of harmful pollutants such as sulphur dioxide and nitrogen dioxide seemed to reveal a disturbing outcome.

The rise in pollution during Diwali affects you in the following ways:

The PM (particulate matter which is smaller than 2.5mm) enters your lungs and bloodstream and has several health impacts including chronic respiratory symptoms such as painful breathing and shortness of breath which might cause premature death.
High sulphur dioxide levels in the air during Diwali also lead to inflammation of air passages and causes complications in respiration.
A compound called  strontium  found in the atmosphere multiplies by 120 times during the festival and causes bone damage and blood clotting ailments.
Firecrackers contain heavy metals which are toxic to the human body and the amount of magnesium in the air goes up by 22x, which poses a significant threat to all forms of life.
The noise pollution also rises during the festival and in extreme cases, can permanently damage one s hearing.
However, there are a few measures you can undertake to steer clear of the excessive pollutants present in the air:

Limit the amount of time you spend outdoors even while exercising. This is because the air remains contaminated, days after all the festivities get over and the pollutants take a very long time to dissipate.
Even on the road, drive with the windows of your car rolled up to avoid intake of adulterated air and use a face mask if you are a two-wheeler rider.
Plant a lot of green plants inside your house as they purify the air you are breathing and ensure a supply of fresh oxygen.
Install an air purifier in the room to make sure you breathe in fresh, uncontaminated oxygen when you sleep. The air purifier will also help in lessening your respiratory complications.
Also, in case you notice any respiratory or breathing problem, it is advisable that you consult a pulmonologist, to rule out serious health issues.
