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?

Dandruff is characterized by flaky skin on the scalp caused by shedding of the dead skin cells. Although small amount of flaking is normal because of the death of the skin cells, any aberration causes uncontrollable itching and foul odor. Studies state that dandruff is usually caused due to bad hair hygiene.

What causes dandruff?

People diagnosed with a skin disorder called  seborrheic dermatitis  are at an increased risk of this condition. Seborrheic dermatitis can affect many areas of the body such as the sides of the nose, eyebrows, breast-bone and back of the ear. Not combing or shampooing the hair enough can also result in dandruff. Sensitivity to yeast is one of the major causes of dandruff. Dry skin, having been subject to immense stress over a prolonged period of time, unhealthy diet and other disorders such as HIV, skin conditions such as psoriasis or eczema are few of the other reasons behind dandruff.

Ayurvedic Tips To Get Rid Of Dandruff

Contraceptives are generally drugs and devices, which are used to prevent pregnancy. A large number of contraceptives are available which allow the couple to enjoy sex without running the risk of unwanted pregnancies. The general categories of contraceptives are explained below:

Barrier Methods:
i. Male Condom: It is one of the most common forms of contraception. They are worn on the penis before sex is initiated. For safety purpose, a new condom should be used every time the person has sex.

ii. Female Condom: Much like male condoms, these are available at over-the-counter pharmacies without prescription. The condoms can be inserted to the vagina anytime within a period of 8 hours prior to sex.

iii. Diaphragm: This should be coated with a spermicide before sex and placed inside a woman's vagina so that the sperms are prevented from entering the uterus.

iv. Cervical Cap: These are used as replacements for diaphragms because some women may develop bladder infections such as cystitis while using it and these caps have lesser contact with the vagina.

Hormonal Methods:
The main implementation of hormonal changes to provide contraception is the pill. This is the most common form of female contraception available. It comes in two forms:
i. Combined contraceptive pill: Contains a combination of hormones such as progestin and oestrogen.
ii. Mini-pill: Contains only progestin: It is available only with the prescription of the doctor and should be used as per the prescription.

Intrauterine Devices
The intrauterine device (IUD) is a long-acting and reversible form of contraception for women. It is of two types: Copper IUD (contains copper) and Hormone-releasing IUDs (progestin hormone is released into the womb slowly). It is a small device that is fitted inside the womb and it provides contraception by facilitating the prevention of fertilization of the egg.

Sterilization
This is a lifelong option that is available for both men and women. In males, the procedure is known as vasectomy which basically ties and cuts off the tubes that carry the sperm.

In women, two forms of sterilization are available; surgical and non-surgical. Surgically, the fallopian tubes are cut and tied using small cuts in the belly so that the ovaries and uterus are not linked. Non-surgically, coils are inserted into the fallopian tubes so the resultant development of scars leads to complete blockage of the tubes.

Other forms of contraceptives include contraceptive patches, vaginal rings, contraceptive injections, spermicides and contraceptive implants.

Cirrhosis is a severe problem of the liver, wherein the liver stops functioning properly due to long-term damage caused by its exposure to toxic substances like alcohol or viral infections. Every time the liver gets affected, it tries to repair itself through the body s natural healing process. Now, due to this continuous healing process, scar tissue gets formed. With the progress of cirrhosis, resulting in the formation of more and more scar tissue, the liver becomes unable to function properly. 

What are the symptoms of Cirrhosis?
Usually, cirrhosis doesn t have signs or symptoms till the time when extensive liver damage has occurred. In those cases, the signs and symptoms which occur include:

One could sense discolouration in the eyes and skin, giving a clear indication of jaundice.
Excess fluid might get accumulated in your abdomen, resulting in utter discomfort.
One may not feel like having any food due to loss of appetite.
You might have uneasiness and discomfort in your upper stomach, provoking you to vomit.
There can be noticeable swelling in your legs, which make it difficult for you to walk properly.
Drowsiness and slurred speech could also be associated as symptoms of cirrhosis.
There might be redness in the palms of one s hands.
So we see that there are numerous signs and symptoms which you could come across, giving a clear indication of the problem of cirrhosis.

Causes which lead to cirrhosis
There are various kinds of diseases and conditions, which can damage the liver and lead to cirrhosis. Some of the most common causes are:

Chronic alcohol abuse over a long period of time can cause severe damage to the liver, hence resulting in cirrhosis.
The virus out of chronic hepatitis B and C attacks the liver and gradually lead to the formation of scar tissue, thereby resulting in Cirrhosis.
Accumulated fat in the liver due to the intake of an unhealthy diet.
Other possible causes can include:

The genetic digestive disorder is another serious cause behind the occurrence of cirrhosis.
Autoimmune hepatitis, where liver disease is caused by one s body s immune system.
Iron is an important part of haemoglobin as it carries oxygen from our lungs to other parts of our body. The problem arises when too much iron gets accumulated in the system, which can poison organs like liver, heart and pancreas. Presence of too much iron in the liver cause cirrhosis.
Poor formation of bile ducts.
Treatment
Treatment mainly depends on the underlying cause and extent of your liver damage. Some of the treatment options which doctors would adopt are:

People should stop drinking immediately if the cirrhosis has been caused due to alcohol consumption.
As one of the reasons for cirrhosis in non-alcoholic persons is obesity, so making a conscious attempt to lose weight is must if they want to get rid of this problem. Loss of weight and keeping blood sugar under check would gradually make the liver healthy.
Damage to liver cells caused by hepatitis B or C can be healed through the specific treatment of these viruses.
