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?

Hot and Cold therapy is one of the most popular home remedies for any kind of joint pain or muscle sprain. In some cases applying heat therapy and cold therapy alternatively, can help relieve the pain while for others only one form of therapy is necessary. To understand what to use when, one should first understand the effect of heat and cooling on the body.

Applying a heat pack or immersing the affected limb in hot water improves blood circulation and makes the muscles more flexible. Thus, it can help relax a muscle and fasten the healing of damaged tissues. On the other hand, cold therapy or cryotherapy reduces blood flow to the affected site. This helps relieve inflammation and pain caused by it. It can also make the area feel numb by reducing nerve activity temporarily.

Types of Heat Therapy
Heat therapy can be categorized as dry heat and moist heat. Dry heat involves using saunas or dry heating packs to relieve pain. This is also known as conducted heat therapy. As the name suggests, moist heat involves the use of steamed towels, hot baths and moist heating packs. This is also known as convection heat therapy. Moist heat is usually considered more effective than dry heat.

Types of Cold Therapy
Cold therapy may be applied to a part of the body or to the entire body. This includes ice packs, coolant sprays, ice baths, ice massages and whole body, cold therapy chambers.

How to use heat and cold therapy?
The sooner heat and cold therapy is given to a person, the faster they will recover from their pains. Heat therapy can be given to a person for extended periods of time but when giving cold therapy, a person should not be exposed to a cold pack or ice bath for more than 10-15 minutes. Care should also be taken no to apply ice or a frozen pack directly on the skin as it can damage the skin and nerves.

When not to use Heat Therapy?
If the injury site is swollen or bruised, cold therapy is better than heat therapy. Heat therapy should also not be applied to an open wound. People suffering from conditions such as diabetes, dermatitis, deep vein thrombosis, vascular diseases and multiple sclerosis should also avoid heat therapy as these conditions can increase the risk of burns and other such complications. Pregnant women should also consult a doctor before using a hot tub or sauna.

When not to use Cold Therapy?
Cold therapy is avoidable for treating stiff joints and muscles. People suffering from poor circulation and sensory disorders should also avoid using cold therapy without a doctor s supervision.

Causes and symptoms of acute tubular necrosis

Damage or destruction to tube-like structures known as tubules in the kidneys can bring about the development of acute tubular necrosis (ATN) and subsequently, acute kidney failure.

What causes acute tubular necrosis (ATN)?

A lack of supply of oxygen to the cells in the kidney is the most common cause of this condition. The reason as to why oxygen may not reach the cells and tissues of this organ could be restriction or blockage of the pathways. When this happens, the kidneys get damaged. Dehydration is the most important cause of ATN which may be because of loose motions, vomitings, heat stroke etc.

Health conditions such as diabetes, heart attack, and stroke can bring about a decrease in blood flow to the organs resulting in ATN and death of cells. Similarly, the presence of toxic substances in the blood can also lead to tubules damage and change the way the cells function in the tubules.

Other causes that may lead you to develop ATN may be medications, radiology dyes, anesthetics and chemicals that cause your body to react adversely.

In addition to these causes, a number of factors can put you at risk of ATN and there are:

- An injury to the body, more specifically your kidneys can cause clotting of the blood vessels
- An adverse response to blood transfusion
- Instances of septic shock can slow down blood flow to the organs
- A major surgery that can interrupt blood supply to the organs

What are the symptoms of the condition?

The symptoms associated with the condition can vary depending on the severity of the problem.

You may experience:

- Troubles in waking up
- Drowsy feeling even during daytime
- Feelings of lethargy
- Feelings of excessive thirstiness
- Problems with urination
- Fluid retention problems
- Instances of confusion
- Feelings of nausea



Can Acute Tubular Necrosis Cause Kidney Failure?

Benign paroxysmal positional vertigo is among the common causes of vertigo. It is the sudden sensation of the spinning of your head which occurs with the change of position of your head. It is a disorder of the inner ear. It occurs when calcium carbonate crystals accumulate in large numbers in any one of the ear canals and stimulate abnormal fluid movement in the inner ear. This sends false signals of head movement to the brain. This can also crop up post head injury. Rolling over the bed or quick head movements like when sitting up in bed can also trigger this condition. 

The common symptoms of benign paroxysmal positional vertigo are as follows: 

Vomiting and nausea. 
Vertigo Blurred vision
Intense dizziness 
Loss of balance 
Benign paroxysmal positional vertigo may be treated in the following manner: 

Medication to get relief from the spinning of your head. 
Epley's Maneuver involves transportation of the calcium particles to a different part of the ear which will no longer cause any problems. 
Brandt-Daroff exercises. 
Sometimes watchful waiting can help a person to recover without having to undergo any other treatment but it is a long process and often involves risk factors. 
Surgery: This option is used rarely when other treatments fail. 
A very important thing to remember is that vertigo can lead to falls and driving should be avoided. The patient will need support during an episode to avoid injuries.

All About Benign Paroxysmal Positional Vertigo

Our heart is one of the most important organs that must be kept healthy and fit so that we can lead a good lifestyle, however, unfortunately many people still suffer from heart problems. And, one such heart problem is Cardiomyopathy.

What is Cardiomyopathy?

Cardiomyopathy is a disease of the heart muscles that makes it very difficult for the heart muscles to pump blood to the rest of the body. Since the muscles are unable to pump blood effectively, it can lead to heart failure. It is a very serious condition and may require extensive treatment to fully recover from the disorder. 

Different types of Cardiomyopathy

Now we will be discussing about the different types of Cardiomyopathy that can affect an individual.

Hypertrophic Cardiomyopathy - In this case, the heart muscles becomes abnormally thickened, particularly affecting the muscle of your heart's main pumping chamber (left ventricle). The thickened heart muscle can make it harder for the heart to work properly. Most affected people have a family history of the disease.
Dilated Cardiomyopathy - In this case, the muscles enlarge and become weak, therefore they cannot pump the blood. These weak muscles over a period of time become absolutely ineffective and can cause heart failure.
Restrictive Cardiomyopathy - In this type, the heart muscle becomes rigid and less elastic, so it is unable to relax and can't expand and fill with blood between heartbeats.Which eventually does not allow the blood to flow properly.
Arrhythmogenic Right Ventricular Dysplasia - In this rare type of cardiomyopathy, the muscle in the lower right heart chamber (right ventricle) is replaced by scar tissue, which can lead to heart rhythm problems. It's often caused by genetic mutations. This condition can cause a sudden cardiac arrest or heart failure as well.
Symptoms 

Patient may be asymptomatic in the early stages of cardiomyopathy. But as the condition advances, signs and symptoms usually appear, including:

Breathlessness with exertion or even at rest
Swelling of the legs, ankles and feet
Bloating of the abdomen due to fluid buildup
Cough while lying down
Fatigue
Heartbeats that feel rapid, pounding or fluttering
Chest discomfort or pressuretreated
Dizziness, lightheadedness and fainting
Signs and symptoms tend to get worse unless treated.

Complications 

Cardiomyopathy can lead to other heart conditions, including:

Heart failure. Untreated, heart failure can be life-threatening.
Blood clots. Blood clots might form in your heart and may enter your bloodstream, then they can block the blood flow to other organs, including your heart and brain.
Valve problems. The heart valves might not close properly. This can lead to a backward flow of blood.
Cardiac arrest and sudden death.Cardiomyopathy can lead to abnormal heart rhythms which can result in fainting or, in some cases, sudden death.
Treatment 

It can include medications, surgically implanted devices or, in severe cases, a heart transplant, depends on which type of cardiomyopathy you have and how serious it is.

Prevention

You can help reduce your chance of cardiomyopathy and other types of heart disease by living a heart-healthy lifestyle and making lifestyle choices such as:

Avoiding the use of alcohol or cocaine
Controlling high blood pressure, high cholesterol and diabetes
Eating a healthy diet
Getting regular exercise
Getting enough sleep
Reducing your stress
So here are some of the most common types of Cardiomyopathy. These types can affect people of any age group if they lead an unhealthy lifestyle. Cardiomyopathy is a very serious condition and any person  suffering from it should be diagnosed early and given medical treatment as soon as possible.

Plums originally originated in the continent of Asia. They are the member of the plant Genus Prunus, which also consists of apricots, cherries, and almonds. One can t go wrong in adding plums in their diet. Plums have the qualities of being low in calories and they also enable you to meet your daily dose of vitamin A, vitamin C, and fiber needs. Some other amazing benefits of plums are :

Low in calorie content: Plums contain few calories as compared to its portion size, as they are low-energy foods containing 70 calories. There are just 70 calories in two plums of medium sizes. It has been suggested by CDC (Centre for Disease Control and Preventions) that when one includes more amounts of low-energy dense foods in their diet, it can help them to limit their total amount of calorie intake for controlling hunger and weight loss.
Good source of fiber: Plums are very good source of fiber. 2 grams of fiber can be found in two medium sized plums. In average, adults need about 20 to 30 grams of fiber in a day, where most people consume only around 15 grams of fiber. The fiber content in foods can help control hunger. Fiber also helps to add bulk to our stool. It helps to mitigate and prevent constipation. Fiber also has the power to prevent the risks of heart diseases by absorbing cholesterol from our blood stream.
Low glycemic index food: The calories in plum come from the carbohydrates in the form of sugar. In two medium sized plums, there is about 19 grams of carbs and about 16 grams of sugar. Although plums are high in sugar and carbohydrates, plums are low glycemic index food. The glycemic index helps to rank the foods that contain carbohydrate on how and by how much they affect blood sugar. Foods with a high glycemic index can cause a brisk rise in blood sugar. Whereas foods with low glycemic index cause a little bit of rising in blood sugar. And also people who eat too many of high glycemic index food has a high risk of diabetes and also heart disease according to the Harvard School of Public Health. Whereas eating low glycemic index foods helps to control diabetes and also helps in weight loss.
Good source of vitamin A: Eating two medium sized plums can provide about eight percent of a person s daily need of vitamin A or 400 international units. Vitamin A is essential for eye health, development and growth, immune health, reproduction, and bone health. Vitamin A is also known as a fat soluble vitamin.
Good source of vitamin C: It is an important water-soluble vitamin. We need a minimum intake of vitamin C in order to make collagen which also helps in healing of wounds and plums are rich in this nutrient.
