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?

Chronic Obstructive Pulmonary Disease or COPD for short is a respiratory disease that makes it increasingly difficult to breathe; the lungs stop functioning properly. There are mainly two categories of COPD which are emphysema and chronic bronchitis. The primary reason for COPD is longstanding exposure to substances such as cigarette smoke, chemical fumes and air pollutants that damage the lungs gradually.

Initially, the symptoms of COPD may be really mild but over time it may become extremely severe. These include symptoms such as:

Shortness of breath
Coughing with mucous formation
Wheezing or gasping
Tightness in the chest
Feeling tired constantly after doing normal daily activities or after exercising.
In the long run, the damages can prove to be permanent.

Of the two subtypes mentioned, bronchitis is when the airways become inflamed as well as narrowed. People suffering from bronchitis tend to produce sputum which is basically a combination of mucus and saliva.
And the other subtype, Emphysema is the condition when the air sacs in the lungs become affected. The air sacs degenerate and become baggy with lots of holes in it. This, in turn, traps air. This narrows the airways making it difficult to breathe. In COPD, there is a narrowing of the lungs because:

The lining of the airway becomes inflamed
The lining of the airways which is elastic flops
The tissues of the lungs become damaged so there is an exertion on the airway.
COPD, in the long run, can lead to a number of health complications such as heart disorders, lung cancer, respiratory infections, depression and high blood pressure. COPD is treatable but not curable because it is a life-long condition. The following are some of the treatment methods for COPD:

Oxygen Therapy- If you are experiencing low levels of oxygen then opting for a portable oxygen unit will be extremely beneficial.
Medication- Bronchodilators help in relaxing the airway muscles for comfortable breathing. These medications are usually taken via an inhaler. Other medications include corticosteroids, theophylline, vaccines and antibiotics/antivirals.
Surgery- Surgery is usually advised as the last step when the COPD condition has become so severe that all other methods of treatment have failed. This is, more possible, in the case of emphysema. There are mainly two surgical methods: one is bullectomy when the surgeons remove the damaged air sacs. The other method is lung volume reduction which removes the lung tissues that have become damaged.
Adopting certain lifestyle changes can provide relief for the time being. Such alterations include:

Quit smoking immediately, if you haven t already.
Try to avoid passive smoking as much as possible. Passive smoking is as damaging as firsthand smoking.
Give your body the daily dose of nutrition so that the immune system doesn t falter as well.

Laryngitis is basically referred to the inflammation of the voice box or the larynx. It is mainly caused due to infections, which are either viral or bacterial or even fungal. If it is caused due to viral infections, laryngitis may be contagious. Some of the other causes of this disease include the following:

Overuse of voice
Allergies
Acid reflux disease
Smoking
Alcohol intake
Larynx is said to be acute or even chronic. Acute laryngitis is referred to a period of a less than three weeks. It is for a short term. Laryngitis which lasts for more than 3 weeks is usually regarded as chronic laryngitis.

Symptoms Of Laryngitis-
One of the major symptoms of laryngitis is considered the hoarseness of the voice. Other symptoms include dry throat, sore throat or even raw throat. Sometimes there is cough, and difficulty in swallowing. Some people also feel the need to repeatedly clear their throat. Nasal congestion and runny nose are some other probable symptoms of laryngitis.

Homeopathic Medicines For Laryngitis

Argentum Met and Arum Triphyllum   These are usually regarded as the most useful medicines for singers and public speakers. This is because these professionals often suffer from laryngitis due to overuse of their voice. The key symptoms are hoarseness of voice or having a sore feeling in the larynx.
Phosphorus   The violet tickling caused due to laryngitis may be most effectively treated by Phosphorus, which is regarded as the best suitable medicine among other homeopathic medications.
Drosera   This medicine is used for treating laryngitis with a highly nagging cough. This is the best and the most reliable medicine for a dry and irritating cough. There is usually a rough scraping sensation in the throat. In some of the cases, the voice of the affected person may be cracked. There are also incidents where people have difficulty in swallowing food.
Causticum - Laryngitis caused due to exposure to cold air is wonderfully cured by Causticum. It is considered to be one of the top-graded homeopathic medicines for the treatment of laryngitis.
Belladonna and Iodum   Belladonna and lodum are two of the most reliable medicines in homeopathy for treating laryngitis, which is caused due to hoarseness. These have a miraculous power to cure the pain in the larynx. Belladonna is prescribed when voice is hoarse and it is highly painful.
In order to know the best medicine for you, it is advised that you consult a homeopathic practitioner.

Lungs are the most important organ of our body that has the responsibility of taking in the oxygen and releasing out carbon dioxide. When cancer develops in it, the entire body gets imbalanced. Lung cancer leads to more death than any other type of cancer, which is why identifying the symptoms and knowing the causes are instrumental in obtaining a timely diagnosis as well as in prevention of lung cancer.

Symptoms of Lung Cancer

In the early stages:

Persistent coughing

Chest pain

Bleeding

Fatigue

Loss of appetite

Sudden weight loss

Headaches

Coughing up blood

In the later stages:

Bone pain

Joint pain

Facial paralysis

Neck swelling

Blood clotting

Weakness

Sever chest pain

Causes of Lung Cancer:

Smoking: People who smoke are more prone to lung cancer. With the increase in the number of cigarettes you smoke, your chances of getting lung cancer increase too. People who don't smoke but are surrounded by the smokers also have high chances of being affected by this form of cancer.
Exposure to Asbestos: Asbestos is a group of mineral, which is present naturally in the environment. Lung cancer can occur due to the inhalation and ingestion of asbestos fibers.
Exposure to Ranon Gas: Ranon is a radioactive gas, which is formed naturally on decaying of radioactive elements. It is found in low levels in the air that we breathe and the water that we drink. Consumption of air and water having this gas leads to lung cancer.
High Levels of Air Pollution: Presence of high levels of dust particles and pollutants in the air that we breathe can cause lung cancer. 1-2% of lung cancer is caused because of it.
High Levels of Arsenic in Drinking Water: Consuming water with arsenic content is harmful as it directly affects the lungs and when the arsenic content is too high, it may lead to lung cancer.
Exposure to Chemicals: Exposure to certain chemicals like uranium, coal products, gasoline, diesel exhaust and mustard gas can also cause lung cancer.
Family History of Lung Cancer: Chances of getting lung cancer increase if your parents, child or siblings are already prone to lung cancer. In case you have a concern or query you can always consult an expert & get answers to your questions!

Lung Cancer - Symptoms & Causes! 

The lungs are made of tubes through, which air passes in and out for exchange of gases, taking in alveoli. It is a disease of alveoli to which finer air conducting tubes are attached. Over a period of time, with age and exposure to various agents, these tubules get obstructed. The amount of air that can pass through these is reduced, leading to reduced oxygen supply to the lungs and thereby the various body organs.

Symptoms
The symptoms of copd can be easily understood if we realize how copd is caused. The progressive blockage of the air tubes causes less oxygen to reach the tissues, which is the most essential agent for all tissues and organs to function. Reduced supply produces a generalized limitation in physical activity. There are two main components to copd - chronic bronchitis and emphysema. The symptoms indicative of copd are as follows:
1. Chronic cough - also referred to as smoker's cough, the cough is relentless and does not subside with regular cough treatment. This is one of the first indications of copd.
2. Mucus buildup - there is constant buildup of mucus which gets expelled during coughing. The person never feels completely clear of mucus, and the regular cough expectorants do not help relieve the symptoms.
3. Fatigue associated with limited activity - as noted earlier, the reduced capacity of the organs limits their activities. Therefore, regular activities like walking short distances or climbing stairs can induce fatigue.
4. Shortness of breath - the above fatigue is associated with shortness of breath, even with small physical exertion. A person with copd will see marked tiredness and reduced ability to perform routine chores and feel a tightness in the chest.
5. Wheezing - passage of air through the obstructed air tubes produces a whistling sound or wheezing. It is more pronounced when there is mucus accumulation in the airways.
Rarely, frequent respiratory infections, more frequent flu attacks, swelling of the feet and ankles, cardiovascular disease, weight loss, and morning headaches.

Treatment
While there is no cure for copd, once it sets, the following are some ways to slow its progression and reduce severity of the symptoms:
1. Bronchodilators - dilate the air tubes and ease flow of air
2. Corticosteroids - help reduce inflammation and thereby improve airflow through the tubes
3. Flu vaccination - helps curb the frequent flu attacks
4. Antibiotics - to contain infections
5. Pulmonary rehabilitation - a combination of breathing exercise and patient education to improve lung function.
6. Oxygen therapy - in very severe cases, oxygen may be required.
7. Lifestyle changes - eating healthy foods, preventing exposure to dust and smoke, quitting smoking, breathing exercises, bi-annual medical check-ups to monitor lung functions are essential.

Knowing that you have copd is the first step towards managing copd, which can be managed effectively.

Chronic Obstructive Pulmonary Disease - Symptoms and Treatment

If you are suffering from bronchitis, it is important for you to recognize whether your condition is acute or chronic in nature. Bronchitis is a condition that involves the inflammation of the airways between your lungs and the windpipe. The lining of these tubes produces mucus in large amounts that trigger a lingering cough.

Acute bronchitis is the form of bronchitis that onsets rapidly after a virus infection in your upper respiratory tract. The viruses that cause common cold or influenza, are also responsible for acute bronchitis. Moreover, the germs that are responsible for measles and whooping cough may lead to acute bronchitis. In such cases, the condition is referred to as acute infectious bronchitis. In case of dust, smoke, or fumes causing bronchitis, it is referred to as acute irritative bronchitis.

Diagnosis

For the diagnosis of acute bronchitis, you will be inquired about the symptoms you are experiencing.
After that, an overall and detailed physical examination is carried out, which confirms acute bronchitis.
In some cases, the patient might have to get an X-Ray done for ruling out other conditions such as pneumonia.
Treatment
Generally, in about two weeks, acute bronchitis resolves on its own without any medical treatment.
Medications: Several medications may be prescribed for the treatment of acute bronchitis.

Antibiotics: These are usually not used for treating bronchitis, as the condition occurs from a viral infection. However, when you have a bacterial infection, antibiotics may be useful for treating it.
Cough medicine: It is recommended for you not to suppress cough bringing up mucus, as the coughing helps in removing irritants from the lungs and air passages. In case of cough that hampers your activities, you may take cough suppressants before going to sleep at night.
Other medications: In case you have allergies, or suffer from asthma or chronic obstructive pulmonary disease (COPD), an inhaler along with other medications may be recommended for the reduction of inflammation, and for opening the narrowed passages within your lungs.
Prevention

Quit smoking immediately and try to keep away from secondhand smoke.
Keep yourself clean and hygienic during the flu season.
Try to avoid direct contact with people who are sick or infected.
Get a flu vaccine on a regular, yearly basis.
Drink a lot of fluids throughout the year.
Consider using a warm or cool, moist air humidifier for helping to thin the mucus layers blocking your air passages.
It is important for you to consult a doctor on experiencing any symptom of acute bronchitis. This will allow timely diagnosis and treatment, and prevent the condition from worsening.
