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?

Tonsils are the two oval-shaped tissue pads at the back of your throat, which function as a mechanism to protect you from diseases. Any infection of the tonsils is referred to as  tonsillitis .

You can suffer from tonsillitis at any age, but it is more commonly diagnosed in children. Tonsillitis is highly contagious.

There are two types of tonsillitis:

Chronic tonsillitis Longer episodes of acute tonsillitis
Recurrent tonsillitis Recurrent episodes of tonsillitis in a year
Causes

Tonsillitis can cause viral and bacterial infections. The  Streptococcus (strep) bacteria  is a common cause. Some other causes include:

Adenoviruses
Influenza virus
Epstein-Barr virus
Parainfluenza virus
Enteroviruses
Herpes simplex virus
Symptoms

Since tonsillitis has various causes, symptoms too tend to differ. Some symptoms include:

An extremely sore throat
Painful or difficult swallowing
Scratchy-sounding voice
Bad breath
Fever
Chills
Earaches
Stomach aches
Headaches
Stiff neck
Neck and jaw tenderness due to inflamed lymph nodes
Tonsils that become swollen and red in colour
Yellow or white spots on the tonsils
In children, symptoms such as excessive drooling, increased irritability or poor appetite are usually noticeable.

Treatment

If the tonsillitis is mild, especially caused by a virus, it usually doesn t require any treatment. More critical cases of tonsillitis might require treatments such as tonsillectomy (a surgical process used to remove the tonsils) or administration of antibiotics.

Penicillin is the most commonly administered antibiotic. Once commonly performed, tonsillectomy (surgical removal of tonsils) is now reserved for extremely critical cases. 

Causes, Symptoms and Treatment of Tonsillitis

Fever in children is a very common phenomenon, but still parents absolutely dread it. It can completely break your heart to suddenly see a happy, healthy child not getting up from the bed. Your first instinct when that thermometer crosses that dreaded 100 degrees F is to rush to the doctor for an immediate cure. That is probably the best remedy as a doctor can often catch additional signs of any disease that you may miss out on. Beyond that, here is how you can understand about fever in children better and how you can help. Technically, your child has fever when the body temperature crosses 100.4 degrees F.
 
Some children manage to stay active even then, but slowly get bogged down with muscle pain or other accompanying symptoms like cold, diarrhea, vomiting etc.
 
Causes: Fever is normally caused by the body's reaction to fighting an infection. (That is why most doctors say it's a sign of a robust immune system). When the body's natural defense system is stimulated, the core inner temperature rises, thereby making it harder for the bacteria and viruses that caused the infection to survive. Most fever subside on their own but that's a tough thing to accept as a parent who only wants to see their child up and running as soon as possible.
 
What you can do: Keep an eye on that temperature obviously. You need to find a doctor the moment the fever crosses the threshold temperature (101+ for less than three months olds, 102+ for 3-6 month olds and over 102 for older children). You should also see a doctor if there are accompanying symptoms or if you've given a dose of Paracetamol but the fever shows no sign of subsiding. It might happen at midnight and beyond, when no regular pediatrician is unavailable. So it is best to find out which hospital has an emergency center capable of handling such eventualities near your home.
 
Fever medications: It is super important for parents to know that fever medications must be given in the correct dose at the right times based on a child's weight, age, and overall health. An overdose can lead you straight to the emergency room. Don't mix a cold/cough medication that also has a fever medication in it.
 
Home remedies: Encourage your child to drink as much fluids as possible to prevent dehydration. Some doctors advise complete body sponging to bring down the temperature and this can be done as long as it doesn't cool the body too suddenly (there are contradictory notes on this practice, so do consult you doctor before your do this).
 
As parent, it is important you equip yourself with the right knowledge before you provide treatment to your child.

The sound of the word cancer can be really traumatic and the fact the one may most of the time be unaware of this condition can be hard to handle. The same is the situation in the case of lung cancer as it does not produce any remarkable signs and symptoms in its early stages. However, there are ways in which you can be aware of this life-threatening ailment. Here are some tell-tale signs of an early stage of lung cancer:

A stubborn cough:
Beware when a cough is lingering on for long with no sign of relief. When a cough is related to cold and respiratory infection, it will subside within a week or so. But in case the cough is persistent, it can be a symptom of lung cancer. You should never dismiss a stubborn cough regardless of whether it is dry or producing mucus. You should talk to a doctor right away as he can check the lungs and may order for other tests to determine whether you have cancer.

Breathing problems:
Becoming easily winded or shortness of breath is considered the most prominent symptoms of lung cancers. This may occur when cancer blocks or inhibit the airway or when the fluid from the tumor starts building up in the chest. If you find that it is becoming difficult for you to breathe in doing tasks that you found easy before, you should not ignore it.



Wheezing:
When the airways become inflamed, blocked or constricted, then the lungs would produce a wheezing and whistling sound while breathing. It can be associated with a host of other causes that are easily treatable but could also be due to lung cancer.

Headache:
Even though headaches are considered one of the most common health problems, if there is a persistent headache, then it could be a sign that lung cancer has spread to the brain. It is important to understand that all headaches are not associated with the brain metastases. There are times when the lung cancer creates pressure on the superior vena cava which is in charge of supplying blood to the upper part of the brain. This pressure can also lead to headaches.

Pain in the bone:
If the lung cancer has spread to the other parts of the body, then it may produce mild pain in the back and other parts of the body. It tends to become worse during the night when you are resting on your back. But it can be difficult for a commoner to differentiate between muscle and bone pain. In case you are suffering from bone pain, you will see that it is becoming worse with movement. Moreover, lung cancer is also associated with pain in the shoulder, neck, and arm even though it is very rare. You should be very attentive to the pain and aches in the body and consult with an expert at the earliest.

You can easily combat lung cancer if diagnosed and treatment is started in its early stages. In case you have a concern or query you can always consult an expert & get answers to your questions!

Five Signs That You Might Be Suffering From Early Stage Lung Cancer!

Asthma is a respiratory disease that takes place with a variety of symptoms including breathlessness, wheezing and coughing. It usually occurs when the airways get obstructed, which in turn leads to inflammation of the tubes. So how can you recognise the signs and symptoms of asthma? here is a list of ways!

Risk identification: it has been observed by doctors and medical science that there is no specific reason for the onset of this ailment. It can be caused due to genetic as well as environmental factors. So, in order to recognise the symptoms, you will first of all have to take stock of both these factors. Find out if you have any blood relatives who have suffered from this ailment and try to find out how it started and at what age, so that you can watch out for the same warning signs. Also, if you are more prone than others when it comes to allergic conditions like rhinitis and atopic dermatitis, then you are at risk. Other risk factors also include living in a high pollution zone, as well as being overweight, smoking, working within close range of exhaust fumes and other chemicals, and other such factors.

Symptom identification: to be able to identify whether or not you are at risk, you must identify the potential symptoms including persistent shortness of breath, which may strike regularly. Also, another symptom is not being able to sleep comfortably due to excessive coughing and breath shortness as well as shallow breathing and wheezing. You may also experience some amount of chest tightening or constriction. These symptoms will usually get worse if you happen to be suffering from the flu or a cold. 

Respiratory health: if you are suspecting the onset of this disease, it would be a good idea to watch your respiratory health by observing the rise and fall of your breath when you are doing energy consuming and strenuous activities like exercising or other such tasks. Sports induced asthma is an actual condition that can get worse when your lungs are faced with cold and dry air. Also, if you are facing exhaust fumes and chemicals as a part of your job, then you are at risk of occupational asthma, in which case you should watch your respiratory health very closely. These symptoms can also get worse when you are around animals and pets due to the allergens that may trigger wheezing and coughing. A lung function test can be conducted by the pulmonologist in case you are suffering from any of these symptoms and conditions on a persistence and prolonged basis. 

Knowing and reporting your symptoms to the doctor is important for getting timely treatment.
