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, abbreviated as COPD, is an umbrella term which refers to the group of lung infections and diseases that include emphysema, chronic bronchitis, and diseases of the small airways. Most people feel breathlessness, which is caused due to impairment of gaseous exchange that happens because of prolonged damage to the lungs over a period of time.

Symptoms such as fatigue, reduced tolerance to exercise, muscular dysfunction, breathlessness even after simple tasks like walking, anxiety, panic, depression, and mood disorders are associated with major chronic disorders of the respiratory system.

Pulmonary Rehabilitation:

Physiotherapy is an effective intervention to treat patients suffering from COPD. It is the part of a formal supervised, multidisciplinary, and an intensive Pulmonary Rehabilitation Program that helps in treating manifestations of the conditions like COPD and Asthma. It consists of exercises to improve and maintain good lung capacity, resistance training, aerobic exercises, and support to behavioural and lifestyle changes for promoting self- efficacy. Your physiotherapist will choose from the different techniques and positions used to remove the unwanted excess sputum from the lungs and airways. The main purpose of the Pulmonary Rehabilitation is to help in improving the psychological and physical conditions of the pulmonary patients, along with training them for health enhancement techniques. Also, it should be noted that Pulmonary Rehabilitation is the cornerstone of care for patients suffering from COPD that uses integrated care by exploring underutilized opportunities.

Benefits of Pulmonary Rehabilitation: 

There are well-researched evidences of the improvement in the capacity of exercising, less breathlessness and fatigue, better control over condition, and an overall improvement in the quality of life of the patients suffering from COPD and Asthma.

Also, undergoing Pulmonary Rehabilitation lowers the rate of admissions, and re-admissions in hospitals due to recurrence of the symptoms and the related conditions.

It has also been reported that if Pulmonary Rehabilitation is properly undertaken, there is nearly no need for systematic health review to check COPD.

Pulmonary Rehabilitation, being a comprehensive program, helps in restoring fitness and easy breathing through breathing techniques, nutrition, exercise, relaxation, emotional support, medications, self-management, and other strategies for a better life, mainly by helping the lungs and the heart to function better.

How It Works?

Exercise is the key to any Pulmonary Rehabilitation Program for helping the lungs and the heart to function better and adjust to the condition. Some of the following exercises can be recommended based on the medical history of the patient:

1. Lower Body Exercise focuses on the workout of legs via running on a treadmill or climbing the staircase for rigorous training.

2. Upper Body Exercise includes working up the muscles of the arm and the chest by tasks as simple as lifting arms against gravity.

3. Breathing Exercise helps people with weak breathing and increasing their breathing and lung capacity.

4. Strength Training helps in building endurance and better stamina through activities like weight-lifting.

Other than exercise, Pulmonary Rehabilitation Program focusses on helping patients build an understanding of their situation and amend their lifestyles accordingly. This includes helping them understand their medication plan, teaching them to use their inhalers right, quitting smoking, consuming a healthy and balanced diet, and other methods as may be suitable based on their specific condition. Also, they are made aware of their symptoms so that if there is any recurrence, it can be immediately reported to the concerned health professional. They are trained through counseling to manage and deal with panic, anxiety, and depression caused due to their condition.

It helps in treating manifestations of the conditions like COPD and Asthma.

Pulmonary Rehabilitation For COPD & Asthma!

Pulmonary tuberculosis was a fatal disease in the past in India. On an average, 95% of the deaths occur in third world countries, especially the developing ones, due to tuberculosis. In India, the deaths account to 50% out of the 95%. Such is the scenario that everyone is apprehensive if they have a prolonged cough and cold. As sputum with blood is a clear sign that the person is suffering from tuberculosis, steps must be taken promptly and at a swift pace to streamline things for quick care. 

Tuberculosis is an air-borne disease and it can easily travel through the air when the affected person is in contact. In tuberculosis, specific bacteria called mycobacterium tuberculosis affects the lungs. On an average, 10% of such infections progress into acute disease and kill the affected individuals.

The symptoms of tuberculosis are seen more in patients suffering from AIDS as their immunity is often compromised. Early detection can be made possible through a chest X-Ray, microscopic examination, and the nature of the fluids. In case you are suffering from a prolonged cough and cold, you must go for tuberculin skin test or blood test to find out more about the problem.

Why is it important to eat a proper diet during pulmonary tuberculosis?
Malnutrition and pulmonary tuberculosis are interrelated. If you are eating right and inducting all healthy means in your daily lifestyle, it will build your immunity and help fight against grave diseases. When you have pulmonary tuberculosis, the desire or craving for the food will disappear and eventually, your body will wither off. You will lose mass by losing muscles.

So, eating healthily can only help you stay strong to defeat pulmonary tuberculosis. Those who are suffering from tuberculosis face challenges with nutrients in their body. They are deprived of essential micro-nutrients and they have severe deficiencies of zinc, Vitamin A, D, C & E, selenium, iron and copper.

A protein- and vitamin-rich diet can boost the immunity of the body and prevent deadly diseases from wreaking havoc in the body. So, if you are wondering about food, here are a few items that you can eat and few that you can avoid when you have pulmonary tuberculosis.

Food to eat

Kale and spinach are instant sources of high iron and Vitamin B, which will help you power-up your immune system.
Whole grains like wheat, bread and cereals are a must-have during this time-tested period.
Carrots, peppers, tomatoes, blueberries, and cherries are rich anti-oxidants and they can boost your immune system by flushing out the oxidants from the body, which are tantamount to poison.
Vegetable oil (not butter) could be a  green go  during pulmonary tuberculosis.
Food to avoid

Greasy food like beef, chicken, and mutton must be avoided. They can increase the cholesterol level in the body and compromise on the power of immunity.
Avoid margarine and butter. One should not eat cake, pastries, and other food with hydrogenated oil.
Keep an eye on your regular diet, work to build a strong immunity, and always stay healthy. 

How A Right Diet Helps Recover From Pulmonary Tuberculosis?

Upper respiratory infection (URI) is a condition, which involves illness, mainly caused by critical infection in the upper respiratory tract. This region includes the pharynx, larynx, nose and sinus. This infection causes diseases, such as tonsillitis (tonsils get inflamed), pharyngitis (causes sore throat) sinusitis (nasal passage becomes inflamed), laryngitis (voice box in your throat gets inflamed) and common cold.

Causes of upper respiratory infection (URI):
1. Both virus and bacteria cause upper respiratory infection (URI). The most common form of virus causing this infection is known as 'rhinovirus.'

2. The immune system of young adults and children are often very vulnerable. Hence, they are more likely to develop upper respiratory tract infection.

3. URI is also contagious and airborne in nature. So if a person comes in contact with an infected person suffering from URI, he/she is likely to develop this infection.

4. Not washing hands before meals can also cause upper respiratory infection because the virus can be transferred easily to the mouth and can travel into your system.

5. If you have any lung problem or heart disease, you are more likely to be susceptible to upper respiratory infection.

6. Those who already have inflamed tonsils can trigger tonsillitis by drinking any cold or spicy beverage like ice-creams or cold milkshakes.

7. Exposure to some flu or cold can cause pharyngitis. It can also be caused by second hand smoking.

8. Birth defects or structural defects in the nasal cavity or nasal polyps can cause sinusitis. Sometimes the inside part of the nose may get swollen due to common cold and block your ducts. This is a common cause for sinusitis.

Symptoms of acute upper respiratory infection:
1. Congestion in the lungs or nasal area.
2. Whooping cough
3. Running nose due to common cold.
4. Feelings of fatigue and lethargy throughout the day.
5. Your body will start aching without engaging in any physical exercise.
6. You can also lose consciousness in severe respiratory tract infections.
7. Difficulty in breathing.
8. Oxygen levels in blood drop down drastically.

Sometimes in worse cases, acute upper respiratory tract infection (URI) can also cause respiratory failure, respiratory arrest and congestive heart failure. Therefore, it is necessary to book an appointment with a doctor as soon as you start experiencing the above symptoms.

Acute Upper Respiratory Infection: Causes and Symptoms

Tuberculosis is one of the most serious infectious diseases and can easily spread from one person to another when the virus enters the air through a sneeze or a cough. The disease is partly preventable by vaccines. It was once upon a time quite rare, but today has become quite common in urban areas. The emergence of HIV is one of the main reasons for this. HIV is an immune system disorder that weakens the body s ability to fight back against infections. With time, the virus causing the disease has evolved and become resistant to many drugs used to treat it.

Tuberculosis is also more commonly seen in slum areas of the cities. This is because of a lack of ventilation and living in close proximity that makes it easy for the disease to spread from one person to another. Limited access to safe drinking water and proper sanitation also reduces immunity and increases the risk of tuberculosis.

To control the spread of tuberculosis, it is important to treat it and keep away from other people while being treated. People also need to be made aware of the disease and its symptoms. It is important for the general public to understand that tuberculosis can be treated. They should also be informed that treatment of tuberculosis is free. As with most chronic diseases, the earlier treatment is started, the easier it is. 

Thus, if you notice any of the early symptoms of tuberculosis such as 

Weakness
Low fever 
Unexplained Weight loss
Then, you must consult a doctor immediately.

Tuberculosis can be diagnosed through a simple skin test or blood test. In terms of the skin test, the results can take up to 72 hours. It is important to note that this test is not foolproof as it can give a false positive or false negative result. For this reason, this may be followed by a blood test. Treatment for tuberculosis takes the form of oral antibiotics. The disease is no longer contagious after the medication is taken for a few weeks. 

However, taking the full course of medication is essential to stopping medication early can make the bacteria resistant to the drug. Tuberculosis caused by drug-resistant bacteria is much harder to treat.
Thus, to reduce the number of cases of tuberculosis in urban areas, people must be made aware of the disease and its treatment. Proper sanitation and ventilation in their living areas should also be provided. 

Tuberculosis - How It Is Affecting The Urban Population?
