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?

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.

Different Types of Contraceptives and Its Uses

While siblings are the force that breathes life into any family structure, it has also been seen as a challenge of sorts to manage siblings and bring out the best in each one of them. In any family unit, there are a number of entities who need to be nurtured in a certain way to ensure that their identities are not hampered by a "one size fits all" style of parenting. Every child is different and will need to be handled differently. Besides this, there are other related challenges that will contribute to the quality of the relationships between the siblings, as well as the rivalry that they may feel towards each other when it comes to attention, achievements and varied other factors.

Read on to know the ten tips to tackle sibling rivalry:

1. Make Friends before Birth: encourage your first born to connect even before the birth of the new baby by including him or her in the changes you see and feel. Planning for the new baby with your first born will also help in such cases.

2. Staying positive is a big factor that will help the children in feeling confident despite their different qualities and strengths.

3. Comparison is a big no no. Stay away from these kind of comparisons so that the children do not feel like they have to fight with each other for your praise.

4. Time Sharing: Ensure that you divide your time well and indulge each child in his or her area of interest so that they feel like you are always there for each of them.

5. Harmonious Start to the day: this will ensure that the children have a special bond at the end of the day. Make sure that they help each other and divide chores accordingly. The older siblings should be given the care giving tasks while the younger ones should be taught to obey them and play along.

6. Humour them: It is a known fact that humour is the best medicine that breaks even the most tension filled atmosphere.

7. Family Meetings: Hold family meetings to discuss important things and even intense fights so that everyone's needs and issues are addressed.

8. Empathy: Teaching your child to empathize with others will help him or her steer clear of needless rivalry at home too.

9. Ignore the Small: Let them figure out the smaller fights, yet always be there to address the bigger issues so that they know you are there for them.

10. Equal Treatment: Treating them equally does not mean doing the same thing for each of them. It means giving them equal time and attention with personalized treatment to suit varied temperaments. This will also give them a lot of individual confidence which eventually kills any feelings of rivalry.

Why Your Baby's Diet Must Not Miss Papaya

Most women attain menopause between the ages of late 40s and early 60s, the average age being about 51. This is an important milestone in a women's gynecological history. One major change is altered female hormone levels, and this leads to a lot of physiological changes. From hot flashes to mood swings, there is also increased predisposition to osteoporosis and uterine cancer.

If you have not had your menstrual cycles for close to 12 months, chances are you are into menopause. So, that means absolutely no vaginal bleeding anymore whatsoever. However, if you experience bleeding, even spotting, be on the alert. It is not normal and needs to be examined, and if required, diagnosed and treated.

Postmenopausal bleeding or PMB, as it is popularly called, can be due to a variety of reasons. While it could be something as trivial as inflammation of the uterine or vaginal lining, it could also be an indication of more severe issues like cancer.

Atrophic vaginitis: Decreasing hormonal levels lead to increased dryness and therefore inflammation of the vaginal and uterine tissue. This is one of the common causes of bleeding after menopause.

Endometrial atrophy: Also caused by lower hormone levels, the lining of the body of the uterus gradually thins down and can get inflamed.
Polyps: Noncancerous growths in the uterus, cervix, vulva, or vagina can also lead to bleeding.

Infections: General infection of any area along the uterine tract could lead to occasional bleeding.

Cancers: Though only 1 in 10 PMB cases turn out to be cancers, the prognosis improves with early diagnosis and intervention.

Diagnosis: As repeated above, reach out to your doctor if you notice postmenopausal bleeding.  

Diagnostic methods could include the following:
1. Physical exam
2. Transvaginal ultrasound
3. Endometrial biopsy
4. Hysteroscopy
5. Dilatation and Curettage

Treatment: Needless to say, this would depend on the diagnosis. For very minor cases with diagnosis like altered hormone levels, no treatment may be required other than modification of the hormone replacement therapy. For endometrial atrophy and atrophic vaginitis, use of estrogen creams and pessaries would be sufficient. Polyps would require removal followed by cauterization (application of slight heat) to stop the bleeding.

Cancer: This would depend on the type and location and require a combination of chemotherapy and surgery.  Removal of the uterus also may be required in some cases. So, if you have had bleeding of any sort after a year of menopause, do not ignore it. 


Is Postmenopausal Bleeding Normal?
