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?

The lungs are made of pipes - starting from the nostrils all the way to the fine tubules in the lungs, through which the air we breathe passes through. The inhaled air also contains a lot of other particles - dust, pollen, virus, cigarette smoke, etc. Very often, the body is allergic to one or more of these particles, and the bronchi are constantly irritated and inflamed due to their sustained exposure. This causes allergic bronchitis which is identified by symptoms like chronic coughing, difficulty breathing, hoarseness, nasal congestion.

Ayurveda believes that the human body has 3 doshas or bio elements - vata, pitta, and kapha. Any disease is believed to be due to one of these being affected. Allergic bronchitis is believed to be an issue with vata.
1. The most effective treatment for bronchitis is believed to be a glass of milk mixed with 1/2 teaspoon of turmeric powder in it. This mixture is believed to be most effective when taken on an empty stomach and can be had 2 to 3 times a day.
2. Equal portions of powders of dry ginger, long pepper, and black pepper can be mixed with honey to make a smooth paste. This can be had 2 to 3 times a day to see wonderful results.
3. One-half teaspoon of licorice powder mixed in 1 cup of water can be boiled, cooled, and stored to be consumed through the day.
4. A creeping plant known as somlata (ephedra vulgaris) is found to be highly efficacious in relieving asthma. This grows in western himalayas in abundance and is sent in hundreds of tonnes to western countries where ephedrine is prepared from it. The powder made from the whole plant, after drying in the shade and is given in the dosage of 100 to 250 milligrams, mixed with honey or water at the intervals of 8 to 4 hours.

Other formulations

Kapha katari - literally translates as phlegm cutter, this works immediately. The powder needs to be wrapped in betel leaf and chewed slowly. Continue with another 4 doses over the next 24 hours.

Kanakasava - the extract of datura is very effective in halting bronchitis but needs to be taken under medical supervision only. This is habit-forming and therefore, needs to be used cautiously.

In addition, follow these general considerations too:
1. Avoid or minimize exposure to known allergens, cigarette smoke and pollution
2. Drink about 8 to 10 glasses of water to help form a thin mucous
3. Avoid dust in the bedroom, avoid feather pillows
4. Regularly vacuum clean the house
5. Do yoga, especially the breathing asanas which are very beneficial for bronchitis patients
Allergic bronchitis is a chronic condition, and acute attacks can be avoided by following some of the pointers mentioned above.

Ayurvedic Treatment Options for Allergic Bronchitis

Radiotherapy is a kind of treatment that kills the cancer cells by using high energy beams. Specialists use radiotherapy to treat a wide range of lung cancer. For early stage lung cancer, the radiotherapy may get rid of the cancer totally. For the small cell lung cancer you may have radiotherapy only. Then again you may have it with another treatment, for example, chemotherapy or surgery.

For small cell lung cancer, radiotherapy is used with or after chemotherapy. Chemotherapy makes the tumor in the lung shrink. You may have radiotherapy to your cerebrum, which tackles any cancer cells that may have spread to the brain. This is called prophylactic cranial illumination (PCI). In case of advanced lung cancer, the treatment contracts the tumor and controls it for a while. It additionally decreases symptoms like shortness of breath.

The types of radiotherapy used for the lungs include:

Outer radiotherapy: This kind of radiotherapy comes from a machine and is administered to the body through an external source. It depends on the kind of cancer and the progression of the same. You may have three radiotherapy sittings every day for around 12 days. This sort of radiotherapy is known as CHART ceaseless hyperfractionated quickened radiotherapy. A few people with small cell lung cancer may have treatment twice a day. If you are getting radiotherapy to control the side effects of lung cancer, you may have a single treatment or day by day medications for up to 3 weeks.



Inner radiotherapy: This is called brachytherapy or endobronchial treatment. This will be administered during a bronchoscopy. The radiation is given through a thin tube that the specialist puts inside your aviation route for a few of minutes. Specialists use this sort of treatment to shrink a tumor that is blocking or pushing your breathing track and making breathing troublesome for you.

These are some of the procedures that take place while you are having lung cancer radiotherapy:

Radiotherapy machines are enormous. The machines are fixed in one position or are sometimes ready to go around your body to give treatment from various angles.
Prior to your first treatment, your radiographers will clarify what you will hear and see. The treatment room normally have docks for you to connect to music players. So you can listen to your own choice of music.
You cannot feel radiotherapy when you really have the treatment. It takes anything from one second to a few minutes. It is essential to lie similarly situated every time, so the radiographers may take a short time to get you prepared.
Once you are in the right position, the staff will allow you to sit in the space for a couple of minutes. They watch you constantly on a closed circuit TV screen. They may request that you hold your breath or take shallow breaths during the treatment.
In case you have a concern or query you can always consult an expert & get answers to your questions!

Radiotherapy For Lung Cancer!

Lung cancer is the cancer killer of both men and women in the world. When you think of risk factors for lung cancer, what comes to mind? Most of us think about the risk associated with smoking cigarettes, but did you know that air pollution can also cause lung cancer? Overwhelming evidence shows that particle pollution in the outdoor air we breathe like that coming from vehicle exhaust, coal-fired power plants and other industrial sources - can cause lung cancer. Particle pollution increases the risk of dying early, heart disease and asthma attacks, and it can also interfere with the growth and function of the lungs. 

What is Particle Pollution?

Particle pollution is a mix of tiny solid and liquid particles in the air and can be made up of a number of components, such as acids, organic chemicals, metals, soil and dust particles. It can be emitted directly from wood stoves, forest fires, vehicles and other sources, and it can also form from other types of pollution that come from sources like power plants. 

Why does particle pollution harm our bodies?

While breathing in larger sizes of particle pollution can be harmful to our health, smaller particles are more dangerous. Bigger particles can irritate your eyes, nose and throat, but our natural defenses help us to cough or sneeze them out of our bodies. Unfortunately, those defenses don't keep out smaller particles, which get trapped deep in the lungs and can even get into the bloodstream, causing damage to our health.



Who is most at risk?

As for who is at risk for health problems from breathing in particle pollution. Those who live where particle pollution levels are high is at risk. Some people face higher risk, including children, the elderly, people with lung and heart disease and diabetes, people with low incomes, and people who work or exercise outdoors.

How do we protect ourselves from particle pollution?

Check the air quality index forecast for the day and limit your activity if pollution levels are high. Avoid exercising along heavily traveled highways regardless of the overall forecast.

As individuals, we can play our part in reducing air pollution levels by trying to avoid creating more of it. Choosing  active travel  options where possible, like walking and cycling, can help reduce pollution levels from transport and is also a great way to be more active, which is linked to a reduced risk of cancer and other diseases. In case you have a concern or query you can always consult an expert & get answers to your questions!

The Connection Between Lung Cancer & Outdoor Air Pollution!

We take the act of breathing for granted, but for many people this simple action can be quite difficult. Difficulty breathing is one of the characteristic symptoms of asthma. This is because of an inflamed, narrow airway. Asthma can be allergic, hereditary, emotional or occupational in nature and can significantly lower the quality of a person s life.

Homoeopathy is a holistic form of treatment that addresses not only the symptoms of a problem, but its root cause. This form of treatment takes into consideration the physical, mental and emotional state of a person. It has negligible side effects and hence can be prescribed to people of all ages. 

Some of the most frequently prescribed homeopathic remedies for asthma are:

Ipecac: This is used in cases where the patient suffers from sudden wheezing, dyspnoea, anxiety and feels a weight on his chest. In such cases, the asthma is aggravated by motion and a constant cough often causes gagging and vomiting.
Arsenicum: Arsenicum is beneficial in cases where the patient is elderly and asthmatic attacks are more frequent after midnight. These patients suffer from anxiety, restlessness, burning in the chest, dry dysponea and fear suffocation. Allergic asthma caused by humidity can also be treated by arsenicum.
Antim Tart: This is prescribed to patients who suffer from a rattling cough with little mucus expectoration. In many instances this cough is triggered by eating and can be relieved by lying on one side. This type of asthma also makes the patient feel drowsy and weak. Antim Tart is especially beneficial for young children and elderly people.
Nux Vomica: Asthma can also be triggered by gastric troubles. In such instances breathing is more difficult in the morning and is marked by a dry cough and a feeling of fullness in the stomach. Nux Vomica is an excellent remedy for such types of asthma. These asthmatic cases also worsen in winters and may be accompanied by a headache or stomach ache.
Carbo veg: This homoeopathic remedy is prescribed in cases where the patient s face turns blue at the time of an asthmatic attack. These patients also suffer from stomach troubles and a cough accompanied by itchiness in the larynx. Along with this, they tend to feel cold, especially in their hands and feet.
Though homoeopathy has negligible side effects, it should not be used to self medicate. Homeopathic medicine should be prescribed only after the doctor has a thorough physical and emotional understanding of the patient.

Asthma - 5 Homeopathic Remedies to Help You Treat it

Any ailment can cause a breakdown of one's overall well-being due to the onslaught of related symptoms, and sinus problem is no different. Sinusitis refers to inflammation or swelling of the tissue that lines the sinus, which are passages filled with air and lie in the nasal tract. 

Sometimes, these passages get blocked with germs, fluid and other elements that can give rise to infections and allergic reactions. Here are the ways in which this condition can affect your health:

Related ailments: one of the most common outcomes of sinus blockage is common cold, which can happen when the passages do not get proper movement of air. Further, it can also cause allergic rhinitis which is also known as hay fever and comes with its own set of symptoms like a runny nose, blocked nose and ears, watery eyes and other signs. A build-up of nasal polyps can also take place in the blocked path of the sinus, while the nasal cavity can also shift, causing a deviated septum. 

Pain: we have many sinuses that are located in various parts of our head, including the areas above and below the eyes. As a part of the sinus attack, one may experience pain and fluid fullness in these areas. These regions can ache when there is a sinus infection. This pain can also be caused by the dull pressure exerted by inflammation, and the pain can then travel down to jaws, teeth and even between eyes. 

Headaches: the constant pressure and persistent pain in the various areas containing the sinus can lead to long term headaches which will be at their worst in the mornings. This is due to the fact that the fluids have been accumulating throughout the night. These headaches can get worse if there is a change in the temperature. 

Congestion: congestion is also a common symptom of sinus infection. The swollen sinuses can lead to constrictions in the nasal passage, which can obstruct normal breathing. This will lead to congestion, which can also affect the senses of taste and smell. 

Cough and discharge: a patient suffering from a sinus infection may end up blowing his or her nose more often than normal. This will usually happen because a yellowing greenish discharge will drain into the nasal passages on a regular basis during the infection. When this discharge bypasses the nasal tract and reaches the throat, it can also cause persistent coughing. It is best to ask for medical intervention and practice steaming to relive the painful symptoms of this condition.
