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!

Necrotizing enterocolitis is a disease that causes inflammation of the tissues present in the intestines and results in damaged tissues. It initially affects the inner lining which ultimately results in thickening of the intestine. It may also lead to a hole in the abdomen resulting in bacteria entering the intestine, thus resulting in infection.

Symptoms-
The symptoms of necrotizing enterocolitis are:

You may experience symptoms of bloating in the abdomen
The abdomen may be discolored
You may experience diarrhea and vomiting
You may not feel hungry
There may be presence of blood in your stool
You may have a fever and constantly feel lethargic
Causes-
Lack of blood and oxygen in the intestine causes it to become weak and increases the chances of necrotizing enterocolitis. It may result if oxygen levels drop during a difficult delivery. If the intestines are weak, then they are at a higher risk of getting infected by bacteria. If you have an excessive supply of blood cells in your body or other stomach condition, then it may lead to this disease.

Diagnosis-
Usually the doctor conducts a physical exam to detect the symptoms of this disease. If babies are born with this condition, then they may suffer from weak immune system and problems in blood circulation. The doctor may also recommend x-rays to get detailed images of the intestine in order to probe for symptoms of inflammation and damage.

Treatment-
The treatment of the disease depends on few factors such as:

The child's age
How far has the disease progressed?
Health of your child
It is recommended to stop breastfeeding. Feed the baby through intravenous methods. The doctor may also recommend antibiotics and oxygen support if the child has breathing problems. In severe cases, the child may require surgery to treat this disease.

If the treatment occurs early, then the child may recover. However, complications such as a narrow and damaged bowel may persist. This may cause problems in nutrient absorption in the intestine leading to other disorders.


All About Necrotizing Enterocolitis

The chronic obstructive pulmonary disorder is a highly prevalent lung disease. People affected by COPD suffer from difficulty in breathing which can hamper regular life to a considerable extent. Though there is no particular cure available for this condition so far, it can be essentially managed with lifestyle changes and proper treatments. This first step in the process is to quit smoking.

Which medicines are available for treating COPD?
Doctors use various medications for treating the symptoms and complications of this disease. Drugs that fall under any of the categories mentioned below, coupled with therapy sessions would be recommended.

Bronchodilators: These medicines which tend to come in the form of an inhaler help in relaxing the muscles around the airways. It can assist in relieving coughing and shortness of breath making it easier to breathe. You may need a short-acting bronchodilator to provide quick relief and a long-acting bronchodilator to use on a regular basis.
Combination inhalers: For those patients whose condition is severe and experience frequent flare-ups, combination inhalers are used. As the name implies, it is a combination of steroids and beta-agonist employed in the short or long acting bronchodilator. Your doctor might recommend this depending on your condition.
Theophylline: This class of medicine is quite inexpensive which is commonly used in the treatment of COPD and asthma. It can improve breathing while preventing flare-ups. But the side effects of this medicine are many and may include fast heartbeat, headache, nausea, and even tremor. Hence, your doctor might advise this medication only if it suits you.
Can lung therapies help in treating COPD?
Doctors often use additional therapies for the treatment of moderate to severe COPD:

Pulmonary rehabilitation program: These programs include exercise training, education, nutrition therapies and counseling. The affected person needs to work with the professionals who can tailor the rehabilitation program for meeting their specific needs. This treatment can shorten the duration of hospitalization and increase one s ability to take part in daily activities.
Oxygen therapy: If there is a lack of oxygen in the blood, you would need additional oxygen to supplement it. There are several types of equipment available in the market that can deliver oxygen to the lungs. Some of these are lightweight and portable which you may carry with you while running errands.
Is there any surgery available in the treatment of COPD?
Surgery may be the only option for people who have a severe form of COPD and emphysema. Some of the most common surgical interventions include bullectomy, lung transplant, and lung volume reduction surgery. There are individual risks and complications in each of these cases, and therefore, it is very important to manage the symptoms to avoid the need for surgical operations.

Thus, with caution and care, COPD can be managed effectively, and you may lead a normal life.


COPD- How Can It Be Treated?

It is a known and proven fact that eating while consuming alcohol is necessary. One tends to grow hungrier, the more he or she drinks alcohol. This is because alcohol has the attribute to stimulate one s appetite in such a way that one would have you craving for food that is rich in salt and high in fibre. Consuming only alcohol ignoring the hunger would lead to several diseases like pancreatitis and issues with the liver.

Though the appetite of an individual during alcohol consumption tends to incline towards snacks like pizza, french fries, nuts and cheese cubes, it is wise to opt for healthier food choices. Salty food can worsen the dehydration effects of the body. And as the body tends to be dehydrated during drinking, it is better to avoid salty food. High-fibre food items are not good for the health either. It delays the digestion process, which is not a good sign for the body. Also, it is also not advisable to eat food in large portions before going to bed, especially after alcohol intake.

There is a variety of healthy food that one can eat along with alcohol

Soup: A clear soup, like chicken clear soup or vegetable clear soup, which has a broth-like texture, is a healthy choice. Creamy soup with cream of chicken or cream of mushroom should be avoided as it would make one heavy, thus delaying the digestion process.
Rice: Plain rice is said to be one of the best food that is easy to digest, paired up with a light vegetable dish. It is very nutritious as well.
Chicken sandwich: Grilled chicken sandwich without cheese and mayo is a healthy food tip as it contains sodium.
Popcorn: Popcorn does not contain fat, neither is it high-fibre. It is the best low-calorie food to go along with alcohol and it tastes really good too.
Wheat crackers: Wheat crackers contain whole grains. It is full of complex carbohydrates, which help the alcohol to absorb easily. It also consists of Vitamin B, which like potassium, gets reduced with the consumption of alcohol.
Banana: It is rich in potassium. Though an individual would never have a banana along with alcohol, it is healthy as the level of potassium should be taken care of while drinking alcohol.
Wheat bread: Wheat bread toast can be consumed with alcohol without butter or cheese. It is an alternative to wheat crackers for those who do not prefer it.
Oats: Cooked food is easy to digest with alcohol, so a pot of cooked oatmeal can be a healthy accompaniment. It can be spiced up a bit to add flavour.
Salad: Salad is refreshing and healthy at the same time. It can be bland, but it is better to have healthy salad as an accompaniment than having salty food with alcohol.
Milk cereal: Cereal, especially whole grain cooked with low-fat milk, is healthy.
By being aware of the right eatables, the ill effects of alcohol can be mitigated to a large extent.

Alcohol - 10 Healthy Foods that You Can Eat With It!

Asthma is something which affects quite a large number of people. As a matter of fact, up to 20 percent of the population is affected by it. Isn t it surprising that the ways to treat it are not so well known, taking into account how many people it affects? So, wouldn t it be a great idea to learn more about it and learn to treat it in a pretty unique way?

When a person has asthma, the airways of the respiratory system become narrower than they usually are and this, in turn, leads to a shortage of breath. While many people would normally go to a conventional doctor in order to treat asthma, it may come as a rude shock to know that asthma is often triggered by reactions to conventional medicines such as non-steroidal anti-inflammatory drugs, which are also known as NSAIDs. Things are not that straightforward, are they?

Ayurveda is a body of medicine which looks not at just patching up and fixing medical problems, but rather to maintain a high level of overall health. Considering this, it should not be much of a surprise to come to know that when it comes to the treatment of asthma, Ayurveda is not superficial like a lot of other methods of treatment. As a matter of fact, it not only looks at the respiratory system but also at the gastrointestinal system in order to provide a comprehensive solution for a patient who is affected by asthma.

According to Ayurveda, the body is divided into three doshas and in the case of asthma, it is the kappa dosha which is culpable. If the asthma is detected before too long, a fully effective treatment can be undertaken and the patient can be restored to his or her pre-asthma level. However, if there is a significant delay between the time that asthma sets in and its detection, only management is possible.

Foods which trigger asthma are to be avoided like the plague! Examples of these foods happen to be animal products and dairy products such as curd. In addition to this, bananas and sugary foods or sweets, including sugar, in itself, are to be avoided.

A paste of rock salt, mustard oil or clarified butter can help if it is rubbed on the chest. Medicines such as Sitopalaadi choorna are to be taken, with this specific medicine ingested with honey. Kapha kartari addresses the issues with the Kapha and with it, asthma should be on its way to becoming a minor problem pretty soon!
