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?

What is Bronchits?

A cold or the flu runs its course in a couple weeks, if you re lucky. After that, you re back to normal. But sometimes you may get bronchitis, too.

That s when your bronchial tubes, which carry air to your lungs, get infected and swollen. You end up with a nagging cough and a lot more mucus.

Types:

-Acute bronchitis: This is the more common one. Symptoms last for a few weeks, but it doesn t usually cause any problems past that.
-Chronic bronchitis: This one is more serious, in that it keeps coming back or doesn t go away at all. It s one of the conditions that makes up what's called chronic obstructive pulmonary disease (COPD).

Causes:

Most often, the same viruses that give you a cold or the flu also cause bronchitis. Sometimes, though, bacteria are to blame.
In both cases, as your body fights off the germs, your bronchial tubes swell and make more mucus. That means you have smaller openings for air to flow, which can make it harder to breathe.
If any of these things describe your situation, you have a bigger chance of getting bronchitis:
You have a weaker immune system. This is sometimes the case for older adults and people with ongoing diseases, as well as for babies and young children. Even a cold can make it more likely since your body s already busy fighting off those germs.
You smoke or live with a smoker.
You work around substances that bother your lungs, such as chemical fumes or dust. (Examples: coal mining, working around farm animals).
You live in or travel to a place with poor air quality or lots of pollution.
Symptoms:

-Cough and production of mucous or sputum are the two most common symptoms of bronchitis.
-Due to excess production of mucous within the bronchial tubes, the cough reflex is induced in a bid to get rid of the mucous. The mucous is usually whitish in colour.
-Often patients feel shortness of breath. This shortness of breath is aggravated on any physical activity like walking, running or climbing stairs.
-There may be wheezing in the chest while breathing. A sensation of tightness or heaviness in the chest may be felt.
-Exercising or running or climbing stairs is often difficult as the compromised lungs are unable to meet the increased requirements of oxygen.

Diagnosis:

Your doctor usually can tell whether you have bronchitis based on a physical exam and your symptoms.She ll ask questions about your cough, such as how long you ve had it and what kind of mucus comes up with it. She ll also listen to your lungs to see whether anything sounds wrong, like wheezing.

That s usually it, but in some cases, your doctor may:

-Check the oxygen levels in your blood. This is done with a sensor that goes on your toe or finger.
-Do a lung function test. You ll breathe into a device called a spirometer to test for emphysema (a type of COPD in which air sacs in your lungs thin out and are destroyed) and asthma.
-Give you a chest X-ray. This is to check for pneumonia or another illness that could cause your cough
-Order blood tests.
-Test your mucus to rule out diseases caused by bacteria. One of these is whooping cough, which is also called pertussis. It causes violent coughing that makes it hard to breathe. If your doctor suspects this or suspects the flu she'll also take a nasal swab.

Role of Homeopathy In Bronchits:

When it comes to treating bronchitis, Homeopathy is very effective. In fact it is the most promising system of medicine for the treatment of bronchitis. Here one must mention that the preventable or avoidable causes of bronchitis should be and must be removed. It is very important that one should stop smoking if the patient is suffering from bronchitis. Any sort of pollution should also be avoided. In homeopathy, I have seen pretty severe cases of bronchitis getting cured.

Diet and Non Diet Food:

Eat plenty of fruits, vegetables, and whole grains. You can also eat meats low in fat, chicken, fish, and low-fat or nonfat dairy.

Bronchits - All You Should Know!

Does your baby s skin taste too salty when you kiss him or her? Did he or she not poop after being born? These symptoms indicate cystic fibrosis in your baby, which is a condition that changes the way your body makes sweat and mucus. It also affects the functioning of the lungs and digestive system. The condition occurs from a flawed gene. If you have cystic fibroids, your mucus may be too thick or your sweat can be too salty. Heavy mucus clogging in your lungs may affect your ease of breathing. This is a serious and life-threatening disease, but it affects different people in different ways.

Causes
The gene known as CFTR is present in everybody. It makes a protein which controls the amount of salt and water that are moved in and out of the cells of the body. In case of cystic fibroids, the CTFR gene is broken, which occurs if you inherit two bad copies of the gene. A bad CFTR gene may lead your cells to make the wrong amount of water or salt. This makes the body incapable of getting sufficient oxygen and nutrients, as the body loses them via sweating.

Symptoms
Apart from the primary symptoms, several other symptoms are also likely due to cystic fibroids. The common symptoms which your child may experience are as follows:

Coughing up thick mucus, wheezing and shortness of breath
Sinus infections, pneumonia, or very frequent bronchitis
Development of polyps in the nose
Bulky, oily and foul-smelling stool
Low bone density, widening and rounding of the fingertips and weight loss
In later life, cystic fibroids may cause liver disease, gallstones or pancreatitis.
Treatment
There is no specific treatment for cystic fibroids. Several treatments are followed for relieving the symptoms and help patients feel better, breathe easier and have lesser infections or stomach problems.

Airway clearance technique can help you with breathing as the mucus from the lungs is cleared in the process. There are several ways to undertake airway clearance and special devices can be used for assistance.
Several inhaled drugs such as salt solutions, steroids and antibiotics are used in thinning the mucus, clearing the lungs and fighting infections.
Several medicines are used for fighting the inflammation and reducing swelling in the lungs.
In case your pancreas are not working properly, you can take enzyme pills for digesting proteins and fats for absorbing more nutrients from the food you take.
Vitamin A, E and D supplements provide the nutrients, which your intestine cannot absorb.
In case you experience the symptoms of cystic fibroids, you should visit a doctor immediately. This will allow you to go for an early diagnosis and effective treatment.

Cystic Fibrosis - Can it be Life Threatening?

Laryngitis is referred to as the inflammation of the vocal cord or the larynx situated in the throat either due to it s over usage or certain infections. This condition spreads rapidly and does significant damage to the larynx. Laryngitis can be acute or chronic. If not diagnosed timely, laryngitis can cause significant problems in the respiratory system such as experiencing trouble while breathing. Laryngitis can be treated with antibiotics and with other home remedies such as gargling with warm salt water, giving your voice some rest and drinking sufficient water (around 2-2.5 liters) in a day to keep dehydration at bay. Make sure you avoid any caffeinated beverage and alcohol if such a condition develops. In urgent cases of laryngitis, a prescribed dosage of corticosteroids and antibiotics can provide relief.

Causes
The causes of laryngitis depend considerably on the form of laryngitis. If the laryngitis is of acute nature, then it might have been caused due to an infection and it tends to go away after suitable treatment. In the case of chronic laryngitis, the inflammation is caused due to a frequent exposure to irritants. This condition has long sustained effect and tends to be painful. The causes of laryngitis are as follows:

Apart from viral and bacterial infections, an acute form of laryngitis can be caused due to the impairment of the vocal cord as a result of constantly talking or screaming at a high-pitched voice.
Acid reflux (acidity) and frequent instances of sinus infections can cause chronic laryngitis.
Excessive consumption of tobacco and alcohol might cause chronic laryngitis.
Constant exposure to toxic chemicals might cause chronic laryngitis.
In some cases, prolonged huskiness of the throat might be a symptom of a serious underlying medical condition such as cancer or vocal cord paralysis. In such a case, you should seek medical attention as soon as possible.
The symptoms of laryngitis are as follows:

A constant sensation of dry throat which might lead to permanent impairment of voice
Persistent sensation of titillation in the throat coupled with a persistent dry cough
Significant pain while swallowing food
Feeling of fullness in the throat
Severe pain in the throat

Laryngitis - Signs You Are Suffering From It!

Tuberculosis is an airborne communicable disease that mainly affects the lungs. However, it can attack the other organs as well. A tuberculosis infection may be categorised as latent or clinically active. A person is said to be suffering from latent tuberculosis when he or she has been infected with the tuberculosis bacteria, but is protected from the germs by a strong immune system. People showing symptoms of the disease are said to be suffering from a clinically active form of tuberculosis and must seek medical attention as soon as possible.

The symptoms of tuberculosis may be hard to identify as they can be attributed to other causes as well. In some cases, the symptoms may not appear until the disease has reached an advanced stage. Some of the common symptoms associated with this disease are:

Weight loss
Fever
Dry cough
Excessive sweating at night
Unexplained tiredness
Poor appetite
Chest pain
People with a weakened immune system such as those suffering from HIV or those undergoing chemotherapy have a high risk of suffering from this condition. When the disease is in its active form, tuberculosis causing bacteria multiply rapidly and attack the lungs. From here they may spread to other parts of the body, such as the lymph nodes, kidneys, bones, spine, brain and skin. When it reaches an advanced stage, the symptoms vary according to the organ affected. For example, pain in the bones indicates that the bone tissues have been affected while coughing up blood is a sign of TB of the lungs.

Tuberculosis can be diagnosed through a blood test or with a skin test. An x-ray and a lab analysis of your sputum can also help differentiate between latent and clinically active forms of this disease.
In the case of latent infections, preventive therapy is prescribed to kill the germs before they become active. This typically takes the form of a single tablet that must be taken for six to nine months.

Clinically active tuberculosis can be easily treated and cured as long as the patient undergoes the complete course of treatment. Treatment for this disease usually takes the form of oral medication that must be taken for six to nine months continuously. This is because tuberculosis causing bacteria can take a very long time to die. In some cases, multiple drugs may be prescribed to reduce resistance to the drugs. When it comes to tuberculosis it is important to continue taking medication for its full course, even if the symptoms disappear and you are feeling better. 

7 Signs You Are Suffering From Tuberculosis!

As we go about life and routine activities, we may be exposed to a lot of different types of environments. We may have to travel in heavy traffic and may be exposed to vehicular pollution, there may be times when we are at places that allow smoking and that may expose us to smoke from cigarettes. Our nature of work today requires us to be constantly in a situation where we take in industrial fumes and exhausts. Being in any of these conditions temporarily may not be a big matter of worry, but when the incidents get more frequent they may lead to troubles in breathing and diseases such as bronchitis or acute bronchitis.

Acute bronchitis is a condition in which the bronchial tube that carries air to and from the lungs gets inflamed due to different reasons. The biggest hazard related to the inflammation of the bronchial tube is that the patient may suffer from constant coughing and irritation of the throat putting pressure on the lungs. In advanced cases, a bronchial infection may also leave the nodes of the lungs inflamed, making it more difficult for the patients to breathe.

Causes of Acute Bronchitis:

The most common causes of bronchitis include the infection of the bronchial tube with bacteria or virus, which lead to the inflammation of the tube and subsequent bouts of coughing.
A habit of smoking cigarettes or being exposed to cigarette smoke as a passive smoker may lead to the infection of the bronchial tube.
Vehicular smoke and fumes also lead to the inflammation and infection of the tube that plays an imminent role in supplying oxygen to the lungs.
Finally, when one works in a position where he/she is exposed to chemicals or harmful exhausts on a constant basis may also have to suffer from acute bronchitis.
What is the treatment for acute bronchitis?

Bed rest and supportive care such as reducing coughing are the main treatments for acute bronchitis. In most individuals, antibiotics are not needed, especially those who have as cause viral or environmental factors. For some patients who have wheezing with their cough, beta2 agonists may be helpful (bronchodilators). Perhaps the most useful treatments are directed at reducing coughing symptoms with over the counter preparations containing guaifenesin and mucolytics. NSAIDs are often added to reduce inflammation and help relieve discomfort. However, the American Academy of Pediatrics does not recommend giving OTC cough and cold medications to children under two years of age; these medicines may cause harmful side-effects that can be life-threatening to young children.

What natural or home remedies treat and cure acute bronchitis?

Stay well hydrated by drinking fluids
Breath humidified air
Avoid dairy products because they thicken mucous secretions
Avoid alcohol and caffeine because of potential drug interactions
Avoid exposure to environmental smoke and other air pollutants
