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?

Tuberculosis is a highly infectious and potentially fatal disease which primarily affects the lungs. It is highly contagious and can infect other people via the tiny water droplets released by an infected person while coughing or sneezing. Some strains of this disease have the potential to resist drugs, which are commonly used to cure tuberculosis.

Read more to find all about the different causes, symptoms, preventive measures and the treatment of tuberculosis:

Symptoms: Tuberculosis, also known as TB, can be both latent and active. In latent condition TB is not contagious and it does not harm the infected person. But latent TB can change to an active form so treating it in its latent condition is highly advisable. Active TB can be diagnosed due to the prevalence of certain symptoms such as a cough, which lasts for more than 3 weeks, coughing up of blood, unintentional weight loss, chills, chest pain, loss of appetite and fever. Tuberculosis mainly affects the lungs, but can also affect your kidneys, brain and spinal cord.
Causes: Tuberculosis in general is caused by infection. It spreads from person to person by ultra-small droplets, which an infected person releases while coughing or sneezing. Tuberculosis is highly contagious but it is not very easy to catch TB as the immune system of your body fights it off. Also if a patient of TB is under treatment, the person 's disease is no more contagious.
Risk factors: Potentially everyone can be infected with TB but certain factors increase the chances of infection such as a weakened immune system, living in or travelling to certain areas and substance abuse. TB can also cause complications such as spinal and joint damage, liver or kidney problems and heart disorders.
Treatment: Administering medical drugs is the most convenient way of treating TB. But TB is more persistent than normal bacterial infections and utmost care and caution must be taken to treat it. Completion of treatment is highly essential to fully cure TB. Some of the side effects of TB medication include loss of appetite, nausea or vomiting, dark urine and jaundice.

Choosing homeopathy to cure bronchitis

Bronchitis is a respiratory disease where people cough up thick mucus. Bronchitis can either be acute or chronic, with the most common cause of bronchitis being either viral or bacterial infection. Acute bronchitis improves within a few days with proper medications. On the other hand, chronic bronchitis is a serious condition causing constant irritation in the linings of bronchial tubes. The most commonly visible signs of bronchitis are a cough, fatigue, shortness of breath, chest discomfort and slight fever and chills. Exposure to excessive pollutants and smoking can cause chronic bronchitis.

How homeopathy can help you in treating bronchitis

Bronchitis can be treated with the help of homeopathy, which can be instrumental in providing relief, thereby improving your quality of life. In fact, homeopathy can be your best option for treating both the forms of bronchitis, as it offers significant relief from the symptoms as well as helps in improving your health in totality.

In the case of acute bronchitis, homeopathy can shorten the duration of the illness to a great extent. When a patient is on the homeopathic treatment he/she experiences a marked reduction in toxicity as well. For the management of an acute attack of bronchitis, the prescribed homeopathic medicines may have to be taken at shorter intervals, after every few hours.

Chronic bronchitis, though contagious, can be treated by homeopathy as well. The symptoms of chronic bronchitis can be significantly improved by homeopathic remedies. It can even aid the patient in quitting smoking.

The most important aspect of homeopathy treatment in the management of bronchitis is that the medicine works very fast and does not leave you weak and drained at the end of the infection.

Here's a Reason for Choosing Homeopathic Treatment for Bronchitis

It is nightmarish when your babies have cough, congestion and stomach aches – and they happen often. The littles ones can't express very well, but as parents you might be able to figure out. Here are common and highly effective home remedies to these baby ailments.
 
1) COLD & COUGH : Honey is highly soothing for temporary cough relief. You can prepare a warm drink with ginger, honey, and lemon juice to drink before bedtime. The ginger and lemon soothe the throat, and the honey loosens up mucus and also acts as a gentle cough suppressant.  Don't give honey to babies ages one or under, though, due to the risk of infantile botulism. For the really little ones, a hot steam vaporizer usually does the trick. 
 
2) NASAL CONGESTION: A stuffy nose is an added challenge with babies and toddlers, as they can’t blow their nose. Prepare a solution of salt in lukewarm water, put this saline solution into the nose, then let your baby lie down for a while, and use the aspirator to remove the loosened mucus. This remedy is safe for babies as well as toddlers.
 
3) STOMACH UPSET/VOMITING:  Stomach aches or infections are the most difficult to get around and can be highly uneasy for the child. Try giving light liquids like dal/rice and vegetable stock, the best that works for everything is breat milk. If you can't breast feed, try to boil fennel seeds (sauf) in milk to make the baby's stomach feel better.

3 Must-know Home Remedies For Every Parent

Lung diseases are some of the most common diseases suffered by human beings throughout the world. Smoking and infections are responsible for most lung diseases. The lungs perform one of the most important functions of the body. It is also one of the most active organs in the human body and hence lung problems can arise due to problems in any other part of the body. Some of the most common and infectious lung diseases are discussed below.

1. Asthma
Asthma is a common long term disease which is characterized by reversible airflow obstruction and bronchospasm. The symptoms of asthma include coughing, shortness of breath and tightness of chest. These symptoms may occur frequently during a day and depending on the person, it may become worse during night or during a certain exercise.

2. Pneumonia
Pneumonia is another common lung problem which is suffered due to inflammation in the microscopic air sacs in the lungs known as alveoli. Symptoms of pneumonia include dry cough, chest pain, breathing problem and fever. Pneumonia is caused most commonly by viruses or bacteria. It is also caused by certain medications and conditions which are popularly known as autoimmune diseases. There are a number of vaccines available to prevent certain types of pneumonia. Other methods include hand washing and refraining from smoking.

3. Tuberculosis
Tuberculosis is a very infectious disease which is caused by the bacteria mycobacterium tuberculosis. Although tuberculosis generally affects the lungs, but it has been known to affect other parts of the body as well. Symptoms of tuberculosis include cough containing sputum with blood, night sweats, fever and weight loss. Air is an active medium for spreading tuberculosis. This happens when people who already have tuberculosis sneeze, cough or speak. Infection occurs more in those who have hiv/aids or those who smoke. Prevention of tuberculosis includes staying away and keeping those who are at high risk, early detection and treatment and vaccination.

4. Mesothelioma
Mesothelioma is a type of cancer which affects the lungs. It affects the lining of the lungs and chest wall. Symptoms of mesothelioma include shortness of breath, swollen abdomen, cough, chest pain, weight loss and general lethargy. Mesothelioma is caused mainly due to exposure to asbestos. Those people who mine asbestos, produce products from asbestos, work with asbestos products are at high risk. Mesothelioma also results from genetical problems and due to infection caused by the simian virus 40.

5. Pulmonary embolism
This is a disease caused due to blockage of an artery in the lungs by a substance which has travelled from another part of the body by the bloodstream. Symptoms of this disease include chest pain, breath shortness and coughing up of blood. There may also be signs of blood clot in the legs.

Types of Lung Diseases

Tuberculosis is a respiratory disease that is very infectious and usually affects the lungs. It is one of the deadliest diseases that have killed millions of people worldwide. According to WHO, 9 million people get infected with tuberculosis in a year. It is one of the top reasons for death among women aged between 15 to 44 years. Symptoms can range from cough, fever, weight loss and night sweats. Moreover, it is an airborne disease meaning that people having tuberculosis can infect many others around them through coughing, sneezing or sharing a glass or cup.

The main cause of tuberculosis is a bacterium called Mycobacterium tuberculosis. However, there are two types of tuberculosis-

Latent TB- In this condition, the bacteria causing TB is present in the body and is inactive. It is not contagious or results in any symptoms.
Active TB- The bacteria causing TB is active and the person carrying it can infect others as well.
Diagnosis
The most common diagnostic test for tuberculosis is a skin test where an injection of PPD tuberculin which is an extract of the TB bacterium is injected into the skin. After 2 to 3 days, the doctor checks the injected site and if there is red swelling, it means that person has TB. Along with this the doctor also uses a stethoscope to gauge the condition of lungs. However, the skin test is not very accurate to know whether a person has TB or not.

Therefore, doctors also use blood tests, x-rays and sputum tests to find out whether a person has TB or not.

Treatments
Tuberculosis can be cured with medications. However, the correct medicines will depend on the type of TB you have and the period of treatment. If you have latent TB, then taking a single TB drug may be enough. But if you have active TB then you need to have proper medicines prescribed by a doctor for at least 6 months. Some common medicines used to treat TB (active) are:

Isoniazid
Rifampin (Rifadin, Rimactane)
Ethambutol (Myambutol)
Pyrazinamide
Also, antibiotics and injections are used to treat drug-resistant TB that may take longer to cure.
When taking medications or any sort of drugs for TB, one needs to be careful and look out for any side effects that can occur due to TB medications. As medicines taken for TB can cause:

Dark Urine
Loss of Appetite
Nausea or Vomiting
Jaundice
For people suffering from Tb, it is important to follow the full course of medications and not to skip taking any drugs that have been prescribed your doctor. There is a program called Directly Observed Therapy (DOT), where the heath care helper administers and look after a TB patient to ensure that the correct course and medicines are given to the patient.
