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 Bronchitis is a result of inflamed bronchioles (pipes carrying air to alveoli or balloons) that can produce mucus and lead to coughing and difficulty in breathing. When smoking causes inflammation of the bronchioles, constriction or squeezing takes place. This results in wheezing because air is travelling through narrowed tubes.

Emphysema, in short, is basically a dead lung. As smoke travels farther down your respiratory tract, the air sacs in your lungs (alveoli), start popping out or dying. Your bank of alveoli gets depleted over time as you continue your habits. You will notice as you increase your heart rate whether its by running or walking a flight of stairs this activity requires your red blood cells to move faster through the alveoli and have less time to receive oxygen from the lung. This leads to having less oxygen on red blood cells whose job is to deliver oxygen to the rest of the body.

Symptoms

In COPD, Both the airways(pipes) and lung parenchyma are affected by the disease and airflow limitation is progressive. COPD has been predominantly seen in patients above 40-yearold and frequent smokers.

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 built up 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.

COPD Is Broken Down To Clinical Scenarios - Chronic Bronchitis & Emphysema!

Asthma is a disease that can be only controlled and not completely cured. This chronic disease can make one feel breathless and experience chest tightening. Modern medicine has an answer to the stressful symptoms of asthma. A wide range of tools and medicines help a great deal in controlling this disease. Find what tools and medicines can help in bringing down the symptoms of asthma and help one breathe with ease.

Pink flow meter: This small tool helps in measuring the movement of air in the lungs. You need to blow into it and read the number. The result helps in finding out the frequency of doctor visits and the dosage of the medicines. Forthcoming asthma attack too is indicated by this device, and you can see it declining with constant use. In fact, you would slowly stop experiencing any other symptoms. Using the pink flow meter forewarns you about a forthcoming asthma attack.

Checkups: You need to visit your doctor regularly. The frequency can vary. You will be seeing your doctor after every two to six weeks, based on the severity of the disease. If you strictly stick to the instructions of your doctor, you can improve the lung function. You can stay active and sleep well if you follow the medicines. This way, there will be no fear of emergency treatment as the peak flow is almost always above 80 percent in case of complete compliance to medicine. Even if you know your condition cannot be cured, you can keep it in check to lead a healthy life.

Medications: Asthma has to be controlled with two types of medicines. You will need to take fast-reacting medicines and the long-term medications. Providing immediate relief is what the quick-relief medicines do, and reducing inflammation of the airways is what the long-term medicines aim at. While there are pills available, the inhalers play a vital role in keeping asthma patients healthy. Through an inhaler, the medication is administered straight into the airways. This makes it easy to give larger and continuous dose of medicines. In fact, this is the most effective way to prevent and treat the asthma symptoms. Corticosteroids are inhaled with an inhaler and it results in long-term relief. Even if taken daily, patients do not get addicted to corticosteroids. Physicians may also prescribe pills that reduce inflammation of the airways. Short-acting b2 agonists are often prescribed as quick-relief medicines. Asthma-affected individuals must carry the inhaler and the quick-relief medicines with themselves, wherever they go.

Treatment for different age groups: In children, only the quick-relief medicines are prescribed. If required, the long-term medications are used after six years of age. If desired results are obtained, the treatment is stopped after six weeks. Children can also be administered corticosteroids. This may result in slowed growth in a few children but the effect does not last long. In elders, long-term inhaling of corticosteroids can increase the risk of osteoporosis. It is essential to take vitamin D supplements along with it. Also, do not take pain suppressants and anti-inflammatory drugs. Speak with your doctor about taking pills for other diseases. When a pregnant mother is asthmatic, the chances of the child getting asthma are higher. They also suffer the risk of premature birth and low birth weight. Check with your doctor about taking medicines for asthma when you are pregnant. You need to consider the risk and stick to safe medication practices.

Brain metastases from systemic cancer are the most common type of intracranial neoplasm in adults, being almost 10 times more common than primary malignant brain tumors, which cause a significant burden on the management of patients with advanced cancer (1). The lungs represent one of the most frequent sources of metastases to the brain, with a probability of (36 64%) (3). Symptoms suffered by the patients include headaches, epilepsy, focal weakness, numbness or changes in mental status. The prognosis of patients with brain metastases is not optimistic and the median survival time is  1 2 months if left untreated. The 1-year survival rate has been recorded as 10.4% (4,5). The treatment of metastatic brain tumors is complex; not only due to being able to provide local control and improve neurological function, but also due to factors such as age, performance and systemic disease status and the size, volume, location and number of metastases at presentation

CyberKnife is a robotic radiosurgery system with a linear particle accelerator (linac), which is coupled with real-time imaging to track and compensate for the patient s or target s motion. As a relatively non-invasive treatment modality, CyberKnife demonstrates certain benefits, including a more accurate target localization and improved dose delivery for the management of metastatic brain tumors that allows higher biologically effective dose delivery without increased incidence of toxicity.

In the present case, the results for the treatment of multiple brain metastases after CyberKnife surgery with a 7 8 Gy marginal dose was promising. CyberKnife for metastatic brain tumors is an effective and safe method for reducing the marginal dose prescribed for multiple brain metastases and for minimizing the radiation-related neurotoxicities. In conclusion, CyberKnife, a focused, highly-targeted radiosurgery and fractionated radiotherapy is particularly useful for multiple brain metastases. CyberKnife provides the advantage of the management of local recurrence and a tolerable complication rate. Although the treatment of brain metastases has been performed with CyberKnife, the clinical significance and optimal dose fractionation scheme require further investigation.
