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?

Corns and calluses are defined as thickened and hardened areas of the skin, which are formed due to excess pressure, friction or rubbing in a particular area. They generally form at the bottom of the feet and can cause discomfort and pain while walking. Corns usually form on the sides and tops of toes. There are several variants of corn such as hard corn, soft corn and seed corns. Calluses typically form in areas which undergo high friction. It can appear on hands and feet. Read on to find more about corns and calluses.

Causes
1. In some cases, corns or calluses may form due to improper walking motion but in most cases corns and calluses form due to wearing shoes which fit in an improper manner.
2. High heels in particular are a major reason for the formation of corns and calluses. Other reasons include foot deformities or wearing shoes and sandals without socks.
3. Corns and calluses have a risk of being infected by bacteria which causes the infected region to secrete pus or fluid.

Symptoms
There are different types of corns and calluses and each of them have different symptoms during their formation.
1. A callus is a small patch of dead skin which can form anywhere in the body but usually in places which undergo friction.
2. A hard corn is a patch of hard skin which is located outside the little toe or on top of a toe.
3. A soft corn is a sensitive red patch of skin which is typically found between toes.
4. A seed corn is a painful patch of dead skin which typically forms on the ball of the foot or on the heel.

Treatment
If you have developed a corn or a callus it is advisable to consult a doctor as they can correctly differentiate between warts and calluses. Use of moleskin around the corn or callus usually reduces the pressure from the affected region. Oral antibiotic medication can also be prescribed by your physician. Certain moisturising creams also help treating corns and calluses. Opt for stronger moisturising creams after consulting your doctor if regular ones are not helping. In certain instances corns and calluses may need to be surgically removed.

The medical name for the yellow tint on your skin and around the white portion of the eye is jaundice. However, jaundice is a symptom of a variety of underlying medical conditions, and not a specific disease. When the body break downs deceased red blood cells, a yellow pigment known as bilirubin is formed. Jaundice develops when your system contains excess bilirubin. Usually, the bilirubin, as well as the dead blood cells, are exterminated by your body.
Jaundice may symbolise a critical problem with your pancreas, blood cells, gallbladder or liver.
Causes:
Jaundice isn t a disease; it is a symptom. Thus if you have jaundice, it might indicate you may have any of the following complications:
Alcohol abuse.
Liver infection.
Liver cancer.
Cirrhosis (Liver scarring mostly due to alcohol).
Gallstones.
Hepatitis (Swollen liver that decreases its functionality).
Pancreatic cancer.
Blood disorders.
An overdose or adverse reaction to certain medications.
Symptoms:
The major indication of jaundice is yellow tinted skin and eyes. In serious cases, the sclera (white parts) of the eye can turn orange or brown. You might additionally exhibit other symptoms such as pale stools and dark urine.
If a concealed condition such as viral hepatitis is causing jaundice, you will probably experience symptoms such as vomiting and excessive fatigue.
Misdiagnosis is common when it comes to jaundice. Sometimes, an abundance of beta carotene (a type of anti-oxidant found abundantly in fruits and plants) can turn your skin yellow.
Treatments:
Since jaundice is a symptom of some other underlying disease, the treatment will focus on that disease. When your treatment starts, the yellow tint will disappear on its own.
If the jaundice is serious, blood transfusions might be needed to expel the excess bilirubin and rejuvenate the body s red blood cells. However, if the body s bile duct mechanism gets blocked, a surgery might be required to unblock the same.

Jaundice: Causes, Symptoms and Treatments

Have you been coughing for a long time and don't know what to do? Well, here are 5 ways in which you can manage your chronic coughing:
1. Give up Smoking: Give up smoking before life gives up on you. Quitting at any point of time slows down the deterioration of lung function though not reverting to non smoking status.
2. Practice Pursed Lip Breathing: It's a very useful technique. Breathe in with your lips sealed up and breathe out with your lips slightly opened as if you're blowing birthday candles.
3. Wear a Mask when Going Out: Be cautious while going outdoor when there is sudden change in ambient environmental temperature and when pollution is high or pollen are there in the environment. (Actually simple mask do not help too much)
4. Stick to the prescribed inhaled treatment - Rush to doctor if there is increase in breathlessness, cough and/or sputum production which is not controlled by ongoing treatment. That marks exacerbation and may need hospitalisation.
5. Get vaccinated - by annual influenza vaccine and if you are above 65 then an additional single shot of pneumococcal vaccine. This will prevent infectious exacerbation.


Chronic Bronchitis - 5 important tips to manage it

Anemia is a disease which occurs due to the lack of red blood cells or hemoglobin in your body. The body transports oxygen and the nutrition you get from food, to various body parts through hemoglobin, and a deficiency can cause lower supply of these important elements to the body. Which is why, the patient may feel a lack of energy, dizziness and even exhaustion. Most people don't realize its existence, so it's important that you know the symptoms, causes and cures of this blood disease. And, the foods one should eat to avoid anemia.

Lack of iron: There are various forms of this illness, and one of it is iron deficiency anemia. The red blood cells in the blood contain hemoglobin, which requires iron for formation. If the diet is not adequately loaded with iron, the person can have iron deficiency anemia. This is the most ordinary one that occurs to people, but with adequate care through food, exercise, and medicines, you can tackle it.
The root cause: Faulty production of red cells (hereditary conditions like sickle cell anemia, bone marrow disorders, etc. is the common cause of anemia. Excessive destruction of red blood cells, which is not compensated by normal production (spleen disorders, thalassemia, etc.) can be another reason. People with blood loss conditions (ulcers, gastritis, internal bleeding, excessive menstruation, childbirth, etc. and the ones who consume a poor diet can also get this blood disease.
Know the symptoms: There are essentially nonspecific symptoms of anemia, but overall fatigue with very low energy levels as the body does not receive enough nutrition to perform various functions can be one of them. Reduced heart rate, fainting, and pallor of skin and whites of the eye are common indicators of this illness. Check with your doctor if you face any of these issues.
Foods for prevention: If you follow a healthy diet that is full of nutrients like iron, you can keep anemia at bay. Remember, weight is not an issue here. If you have a good diet intake, you need not worry about being slim. Often, women who are thin get labeled as anemic, which is far from truth. When it comes to nutrients, iron-rich foods should be eaten along with vitamin C to improve its absorption. Vitamin B12 also plays a significant role in absorption. Meat including red meat, lamb, pork, chicken, beet, ham, turkey, and seafood including salmon or tuna can be included in your diet. Other foods like legumes, soybeans, veggies (dark green leafy vegetables, spinach, peas, broccoli), dried fruits and nuts, tofu, pumpkin and eggs are rich sources of iron that can be consumed by vegetarians. Cereals like red rice, brown rice or fortified cereals with a good source of iron can also be included in the diet.
Don't miss out on iron, ladies! Women are likely to be anemic (with symptoms like fatigue and paleness) and hence they should constantly monitor for iron levels and shift to a diet rich in iron. Furthermore, iron supplements can be consumed in the form of tablets, syrup, or tablets with the guidance of a doctor. In severe cases, where there is a significant blood loss, especially with childbirth or internal bleeding, the sufferer may require transfusion. All in all, anemia is definitely manageable with planning of diet, especially during times the like menstruation and pregnancy. So, taking care on time is a vital step.
