Potassium is an essential mineral which is known as an electrolyte. Electrolytes are responsible for maintaining the ionic balance of your body. Other electrolytes are sodium, calcium, magnesium, phosphate, chloride. These electrolytes bear an electric charge which manages the electrical activity of your health system. Potassium also helps the muscles of the body to function properly. In fact, it has its contribution in regulating blood pressure; a crucial role for a healthy heart.

Potassium deficiency is a kind of medical condition which is known as hypokalemia. The normal level of potassium in the human body should be in between 3.5-5.0 mmol/L. But the deficiency in potassium can cause severe problems including muscle weakness, nerve disorders, heart problems, etc. Kidney is the organ which is known to manage the potassium balance by removing the extra potassium through urine.

Causes of potassium deficiency:

Lack of potassium in diet
Dehydration
Diarrhoea
Too much sweating
Several medicines also cause potassium deficiency

Signs of potassium deficiency:

You are getting wiped out too often: Like it is discussed before that potassium is responsible for your muscles to work actively. Each and every cell needs the required amount of potassium to work effectively. So, a little deficiency of potassium can leave you exhausted throughout the day. If your normal working routine leaves you exhausted and if you are sweating too often, then there is a chance that you are suffering from hypokalemia.
High blood pressure: Potassium plays an important role in maintaining the blood pressure by helping in relaxing the blood vessels. Low potassium can cause the blood vessels to get constricted, due to which your blood pressure increases.
Muscle weakness: Potassium plays a significant role in building the strength of your muscles. Lack of potassium can easily cause muscle weakness, aches and spasms.
Irregular heartbeat: Anything regarding your heart problem can scare you badly; especially when you experience sudden skipped heart rate or when your heart rate doubles. Low potassium can cause such palpitations and skipped heartbeat.
Feeling dizzy: Lack of potassium in your body can slow down your heart rate and make you feel dizzy or you may feel that you are going to faint. Though many other medical conditions can be responsible for such symptoms but hypokalemia is one of them.
Constipation: Potassium deficiency can affect your overall health. You might encounter symptoms like bloating, abdominal cramping etc.
Numbness and tingling: Potassium is significant in keeping your nerves healthy. Potassium deficiency can make you experience numbness, needle sensations on your feet, wrist, etc.
These are the signs that people encounter when they suffer from hypokalemia. Hypokalemia can make you feel extremely sick and it causes several diseases which are discussed above. It is always advisable to visit a doctor when you encounter any of these above mentioned symptoms.

Potassium Deficiency - 7 Signs You Are Suffering From It!

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?

Has your child been coughing frequently? Is the cough chronic in nature, making your child breathe rapidly and does he/she complain about a tightened chest? These symptoms signify that your child is having asthma. Asthma is a medical condition characterized by paroxysmal wheezing respiration dyspnoea. It is common in children and an affected child experiences difficulty in breathing, and a whizzing sound is produced, especially during expiration. Asthma may lead to severe health complications and needs immediate diagnosis and treatment.

Diagnosis: The diagnosis of asthma is based on the symptoms, medical history and a physical examination of the child.

The different modes of asthma diagnosis are as follows:

    Medical history and symptoms: You must tell the doctor about any history of breathing trouble with your child or whether there are chances of other inherited health conditions. You must explain your child's symptoms properly, which may include coughing, wheezing, chest pain or tightness and others if observed.
    Physical examination: A physical exam will be carried out in your child where the doctor will listen to his heart and lungs, and look for eye or nose allergies.
    Medical tests: A chest X-ray of the child has to be carried out, along with a simple lung function test known as spirometry. This test measures the amount of air present in the lungs and determines how fast it can be exhaled. Spirometry enables a doctor to determine the severity of the asthma. Some other tests are also carried out for the identification of asthma triggers. They include allergy skin testing, blood tests and X-rays to know if sinus infections are affecting the asthma. An asthma test determines the amount of nitric oxide in your child's breath.

Treatment: Based on your child's severity of asthma symptoms and his medical history, the doctor will provide you with an action plan to treat the same. This action plan explains all the medications your child requires, the dosage and schedule of the medicines. The plan also includes points on what to do when the asthma worsens and when an emergency treatment is required. Anti-inflammatory drugs are prescribed to children who require bronchodilator medication. All asthma medicines used by adults can be used in case of children but in lower dosages.

You should give the asthma medications to your child using a home nebulizer or a breathing machine. A nebulizer delivers asthma drugs by transforming them from liquid to a mist. The child gets the drug by breathing it via a face mask.

In order to control and manage asthma in children, they must avoid the triggers and should keep away from any source of smoke. A doctor must be consulted to know about the best diagnosis and treatment methods.

Asthma in Children: Diagnosis and Treatment

If you have been diagnosed with asthma, it is important for you to know about the most common triggers of asthma. Asthma is a medical condition, which is characterised by paroxysmal wheezing respiration dyspnoea. It causes breathing difficulties, tightened chest and coughing. By identifying and reducing your exposure to several asthma triggers, you will be able to manage or control your asthma symptoms and the frequency of your asthma attacks. Here are the most common triggers of asthma you should know about:

Allergies that trigger asthma
Allergies, are common problems and over 80% of people are suffering from asthma and are allergic towards substances like weed pollens, animal dander, dust mites, mould and cockroach particles. Children having large amounts of cockroach droppings in their homes are more likely to develop childhood asthma. Dust exposure may lead to dust mite allergy in asthmatic patients.

Food which triggers asthma
Certain food allergies may lead to isolated asthma, where other symptoms are absent. Patients with food allergies can exhibit asthma as a part of anaphylaxis, which are food induced. The common food items which are associated with allergies include eggs, peanuts, cow milk, soy, fish, wheat, shrimps, salads and fresh fruits. Several food preservatives also trigger asthma. They may include sulfite additives such as potassium bisulfite, potassium metabisulfite, sodium sulfite, sodium bisulfate and many others. These are commonly used in food processing and trigger asthma in sensitive people.

Asthma induced by exercise
Strenuous exercise may lead to the narrowing of the airways in maximum people having asthma. Exercise acts as a primary trigger for asthma symptoms in many people. Patients having exercise induced asthma are likely to feel chest tightness accompanied by coughing and breathing difficulties after completing an aerobic workout session. Although the symptoms subside, they may reoccur within some hours. You should warm up properly and slowly before a rigorous workout session to prevent an asthma attack.

Smoking
People who smoke are more likely to have asthma. If you have asthma and still smoke, the symptoms of wheezing and coughing worsen. Pregnant women who smoke increase the chance of wheezing in their to-be-born babies. You should absolutely quit smoking if you have asthma.

Infections which trigger asthma
Several infections such as cold, bronchitis, flu and sinus may cause asthma attacks. The respiratory infections, which are viral or bacterial, are a common cause and trigger asthma, especially in children. Asthma is also associated with severe heartburn. According to studies, more than 85% people with asthma also suffer from heartburn. This is a condition known as gastroesophageal reflux disease or GERD.

Asthma - Common Triggers Behind it?

Asthma is a distressing condition during which people find it difficult to breathe as the bronchi or tubes carrying air to lungs swell up. This happens when mucus inside bronchi comes into contact with an allergen like a pollutant or dirt causing symptoms like wheezing, coughing, more mucus production and difficulty breathing. There is no cure for asthma. As of now, it can only be managed. But managing asthma becomes really difficult during low air quality days, especially during winters when it s cold and dry.

The most common air pollutants are gases like sulphur dioxide, nitrogen dioxide, vehicle smoke, and suspended particles. Each one of them can trigger an asthma attack by itself because of its deleterious effect on the lungs. The smaller the particulate matter is, the more dangerous it becomes as these particles get lodged in the air sacs inside lungs, causing not just asthma from worsening but also fatal diseases like lung cancer.

So, most asthma patients suffer from frequent attacks due to air pollution. How can these attacks be prevented? Here are some tips:

According to research, asthma can be managed by making modifications in everyday life. On high air pollution days due to ozone, for example, asthmatics tend to experience more lung inflammation. If you are an asthmatic, you should reduce time spent outdoors, especially doing strenuous activity in the mornings and evenings. Keeping medications on hand and using those at the very start of an asthma attack also helps. There should always be a plan in place to lessen the chance of an asthma attack on poor air quality days starting from a rescue inhaler to preventive medication if your doctor feels you need it.
Stay hydrated and breathe through the nose. Dehydration is dangerous for asthmatics especially when air quality is bad. In this case, lungs can become badly affected because they need right temperature and levels of water to work properly. It s crucial to breathe through the nose only and not the mouth as the air breathed in from the mouth can be very cold and dry and can cause even more inflammation of the lungs.
Know your asthma triggers and change lifestyle. Avoiding your triggers is key to managing asthma. If traffic fumes are a trigger, it s best to change the route you take to work to manage your asthma. If you don t know your triggers look back at your last asthma attack and remember what you were doing. Did you pet your dog? Write a diary and discuss with your doctor on how to avoid your triggers. Use a face mask when outdoors to limit exposure to allergens. 
Track your asthma to recognise early signs of asthma. If you know that it s getting worse, you should have a fool-proof plan in place.

Air Pollution - Tips to Prevent Asthma From Worsening!

The term asthma and bronchial asthma are often used interchangeably. Bronchial asthma refers to the chronic inflamation of the airways either due to some internal or environmental allergen. This leads to the narrowing of airways, which makes breathing difficult and blocks air from entering the lungs. Children are most affected by this condition as the immune system is still in the process of maturity and often grows out of it as they age. However, if not treated, this can lead to many complications like respiratory failure and can prove to be fatal. Asthma cases often spike in winter months and in the flowering season. It can also be triggered by second hand or passive smoke, stress, sudden unaccustomed physical exercise, food additives, dust, house mites, perfumes, certain drugs and many other allergens. A family history of asthma, allergic rhinitis, atopic dermatitis and other allergic conditions can also increase a child s risk of suffering from this condition.

Some of the most noticeable symptoms of bronchial asthma include:

1. Wheezing 
2. Shortness of breath 
3. Excessive coughing that worsens at night 
4. Tightness of the chest 
5. Lowered energy levels 
6. Rapid breathing 
7. Tiredness 
8. Indrawing of chest and lower neck

These symptoms often worsen after exercising. Lung function test and Chest X-ray are often used to confirm a diagnosis of bronchial asthma. Once diagnosis is being confirmed, it should be categorized as per severity. Your doctor may prescribe medication in the form of pills and inhalants as per the category of disease. It is important to note that these cannot cure asthma, but can help manage it. Inhalers deliver low doses of steroids directly to the lungs to reduce inflammation and other inhaled medication like Beta 2 agonist will open the airway by relaxing the muscles of airway. Children suffering from asthma must be taught how to use the inhalers and should always have it with them. In the case of school going children, their teachers should also be informed about the condition. Parents should also know how to keep it, use it and clean the device in a proper and hygienic way.

In very small kids those inhalational medication can be given by face mask and spacer, but as the age grows or in case of elder children above 6 years of age, they can directly take the medication from spacer. Those children who are already on inhalers, but still face asthma attack , for them nebuliser is the better choice to manage the emergency. It will make the liquid medicine into mist and enters into the air passage easily and work promptly.

In addition, certain lifestyle changes can also help reduce the frequency of asthmatic attacks. Avoid going outdoors on windy days or days when air pollutant level is high. Reduce the child s exposure to allergens like pet hair, dander and dust by dusting and vacuuming on a weekly basis. Avoid the use of humidifiers inside your house as moist air can promote the infestation of dust mites. Try to keep the child in a room with adequate air and sunlight. Take plenty of green leafy vegetables and fruits, which contain lots of vitamins and minerals. If possible get your child to wear cover his or her nose and mouth while in outdoors.
