Diagnosing Asthma And Copd With Pft

Can coronavirus cause patients to develop severe diseases? Does asthma increase that risk?

I explained how a PFT can help diagnose asthma in my post at Asthma.net: What Are PFTs? I explained how a PFT can hep diagnose COPD in my post on this site, What Are PFTs?

So, if you read those, you know what an FEV1 is. You know how this can be used to determine if you have COPD. Still, heres a quick review. You do a PFT. You do a pre and post FVC. A computer determines your FEV1. This is the best indicator of airflow limitation.

You then use a bronchodilator. This can be either an inhaler or breathing treatment. Then you do a second FVC. Heres how you determine if its asthma or COPD.

  • COPD. By its basic definition, its persistent respiratory symptoms and airflow limitation. Your pre and post bronchodilator FEV1 is less than 80%. Your post bronchodilator FEV1 is not much different than your pre bronchodilator FEV1. This shows that airflow limitation is persistent. It is not reversed with time or treatment. This confirms a diagnosis of COPD.1
  • Asthma. By its basic definition, respiratory symptoms and airflow limitation are intermittent and vary in intensity. Asthma attacks are reversible with time or treatment. Your post bronchodilator FEV1 improves by 12% or more. This shows airflow limitation is reversible. This can help make a diagnosis of asthma. 2
  • Asthma and COPD. This is when you have both. Your airflow limitation is reversible. But, your FEV1 remains under 80% despite treatment.

Reducing The Burden Of Asthma

Asthma cannot be cured, but good management with inhaled medications can control the disease and enable people with asthma to enjoy a normal, active life.

There are two main types of inhaler:

  • bronchodilators , that open the air passages and relieve symptoms; and
  • steroids , that reduce inflammation in the air passages. This improves asthma symptoms and reduces the risk of severe asthma attacks and death.

People with asthma may need to use their inhaler every day. Their treatment will depend on the frequency of symptoms and the different types of inhalers available.

It can be difficult to coordinate breathing using an inhaler especially for children and during emergency situations. Using a spacer device makes it easier to use an aerosol inhaler and helps the medicine to reach the lungs more effectively. A spacer is a plastic container with a mouthpiece or mask at one end, and a hole for the inhaler in the other. A homemade spacer, made from a 500-ml plastic bottle, can be as effective as a commercially-manufactured inhaler.;

Access to inhalers is a problem in many countries. In 2019, only half of people with asthma had access to a bronchodilator and less than one in five had access to a steroid inhaler in public primary health-care facilities in low-income countries .

Asthma Medication Is Important

Asthma can be well-controlled with the appropriate medication in almost all people. To maintain and improve your asthma control both in the short and long term, it is important to continue to take your asthma medications;and discuss any symptoms and concerns with your doctor, nurse or pharmacist.

The main types of medication are:

  • preventers that slowly make the airways less sensitive to triggers by reducing swelling and mucus inside the airways. This medication is taken daily. There are also combination preventer medications containing two different medications.
  • relievers that act quickly to relieve symptoms by relaxing the tight muscles around the airways. This medication is used during an asthma attack

How Is Asthma Treated

Take your medicine exactly as your doctor tells you and stay away from things that can trigger an attack to control your asthma.

Everyone with asthma does not take the same medicine.

You can breathe in some medicines and take other medicines as a pill. Asthma medicines come in two typesquick-relief and long-term control. Quick-relief medicines control the symptoms of an asthma attack. If you need to use your quick-relief medicines more and more, visit your doctor to see if you need a different medicine. Long-term control medicines help you have fewer and milder attacks, but they dont help you while you are having an asthma attack.

Asthma medicines can have side effects, but most side effects are mild and soon go away. Ask your doctor about the side effects of your medicines.

Remember you can control your asthma. With your doctors help, make your own asthma action plan. Decide who should have a copy of your plan and where he or she should keep it. Take your long-term control medicine even when you dont have symptoms.

How Long Do You Have To Claim Compensation For Work Related Asthma

World Asthma Day

Generally speaking you have three years from the date of an injury to start your claim for compensation at court, but the three year period only starts to run from the date of injury or date of knowledge of injury.

In other words you will often have three years from when you started to display symptoms of asthma and in some cases: three years from the date you were medically diagnosed with asthma.

If you think you might have an occupational asthma compensation claim you should contact a specialist solicitor immediately to advise if you are in time to make a claim.

If Your Asthma Symptoms Are Caused By Allergies Take Steps To Control Knownor Potential Triggers In Your Environment

Allergy-proof your house for dust, mold, cockroaches, and other common indoor allergens to which you are allergic.

;Reduce your outdoor activities when the pollen count or ozone level is high.

;Choose foods that dont contribute to your asthma or allergy symptoms.

;Evaluate your workplace for possible allergens and take the necessary steps to reduce your exposure to them.

In order to determine relevant triggers, you may want to seek consultation with an allergist who can further define these triggers.

In addition, anyone with asthma should consider getting an annual flu shot. Older adults also should talk with their internist about getting a pneumonia vaccination.

Global Alliance Against Chronic Respiratory Diseases

How does asthma work? – Christopher E. Gaw

The Global Alliance against Chronic Respiratory Diseases contributes to WHOs work to prevent and control chronic respiratory diseases. GARD is a voluntary alliance of national and international organizations and agencies from many countries committed to the vision of a world where all people breathe freely.

Are People With Asthma At Higher Risk Of Poor Outcomes From Covid

Despite the lack of hard data, the WHO, the CDC, and lung disease specialists are in agreement: People with asthma have a higher risk of severe illness and death with respiratory infections in general. Because of this, any child or adult with moderate to severe asthma should consider themselves at risk for severe COVID-19 disease and take extra precautions with their health.;

This is especially true for anyone who has been admitted to the hospital for asthma in the last 12 months, or who has ever been admitted to an intensive care unit for their asthma.;

Why is this recommendation in place when there is no hard evidence? Heres why.;

Any infection in the lung can trigger an asthma attack, causing the smallest airways in the lung to tighten up and let very little air in and out. The symptoms are sudden and severe: shortness of breath, wheezing, and cough. If the infection is mild, for example with a common cold, asthma symptoms can usually be managed at home. Most people with asthma have an asthma action plan that tells them how to manage their symptoms when they get worse, and when to seek medical attention.;

If the infection is more serious, a person with an asthma attack may need emergency treatment in the hospital with oxygen, nebulizers, and corticosteroids. Usually things improve pretty quickly. Antibiotics help to treat a bacterial lung infection if there is one, and flu treatments like Tamiflu can help shorten symptoms if the infection is caused by the flu.;

What Causes Allergies Later In Life

Just like childhood allergies, we do not completely understand why some people develop allergies and others dont. We do know there are complex genetic and environmental factors involved.; Scientists have proposed theories about why allergies occur, including the hygiene hypothesis that attributes allergic disease in part to the use of antimicrobials and the high standard of cleanliness in modern societies.

Adults can also present with new-onset environmental allergies. In some cases, the patient may have had a tendency to develop allergies all along, but their environment changed, putting them in more contact with the triggering allergen .

Benefits You Can Claim For An Occupational Disease

Workers who develop diseases have access to the same benefits as those who suffer injuries. These include compensation for:

  • Medical costs This includes medication, hospitalization, doctors visits, the cost of traveling to appointments.
  • Temporary disability If you need time off to recover, you typically get two-thirds of your average weekly wage prior to the injury. Paralysis and other severe injuries may result in benefits of 80 percent of your average pre-injury wages.
  • Permanent impairment When your treatment is complete or you only have six weeks of temporary disability benefits left, your doctor will determine whether you have any lasting impairment. If you can do some type of work, your doctor will assign an impairment rating. This will determine how long you can get permanent impairment benefits of 75 percent of your temporary total disability rate. This will be halved if youre earning at least as much as you did before your injury.
  • Permanent total disability If you cant do any type of work, you will be eligible for permanent total disability benefits at the same rate as your temporary total disability benefits. These benefits will continue until youre 75 years old. If you dont qualify for Social Security benefits, youll receive permanent total disability benefits for the rest of your life.
  • Vocational rehabilitation; If you cant return to your usual job, you may be eligible for vocational counseling, training, and other help in finding a new job.

How Does Fasenra Work

Fasenra works by:

  • Depleting the number of eosinophils
  • Blocking IL-5 from binding to eosinophils, which prevents IL-5 from helping eosinophils to multiply and survive
  • Enhancing the ability of natural killer cells to kill eosinophils
  • Enhancing the ability of NK cells to kill basophils, which also play a role in the airway-inflammation associated with asthma

Fasenra blocks the action of a cytokine signaling protein called IL-5, which is part of the immune system and plays a key role in airway eosinophilia in people with asthma. Fasenra specifically binds to the IL-5 receptor on eosinophils, preventing IL-5 from binding and its alpha and beta subunits from interacting.

Fasenra also binds to and activates the FcRIIIa receptor on another type of white blood cell called natural killer cells. This enhances apoptosis, or programmed cell death, of eosinophils via a process called antibody-dependent cell-mediated cytotoxicity . It also enhances the apoptosis of basophils. Basophils are yet another type of white blood cell. They also express IL-5R like eosinophils do and play a role in the airway-inflammation associated with asthma.

While Fasenras mechanism of action in the body is known, it is not fully understood exactly how its actions help to treat asthma.

Why Are More People Getting Asthma And Allergies

Some researchers put the increase in asthma and other allergic conditions over the last few decades down to the fact that we live in much cleaner, more urban conditions.;This means we have less contact with the friendly bacteria that thrive in more rural, natural environments.

Along with fewer childhood infections, this has resulted in lowered immunity, and more chance of allergies, including asthma.

The ‘hygiene hypothesis’

The idea that were missing out on exposure to useful microbes early in life began to be considered a while back with a theory known as the hygiene hypothesis. This was based on evidence that children growing up in large families, in unhygienic homes, had fewer allergies, including asthma.

More recent research suggests babies exposed to friendly bacteria in the first few months of their lives are thought to have less risk of developing asthma and allergies.

This is why some studies show that children growing up on farms have fewer allergies, and other studies show that having a dog in the house when your baby is very small can protect them from allergies and asthma. The studies are based on exposure to friendly microbes in babies less than two or three months old.;

But being around animals, or being in a natural environment, may not necessarily protect your child against asthma other factors need to be taken into account, such as if theres a family history of allergy and asthma.;

Can I Qualify For Workers Compensation With Occupational Asthma

Occupational asthma is already widely recognized as an occupational disease. If you are exposed to irritants in the workplace environment that can induce asthma, or if you have been in the past you may qualify to receive workers compensation benefits. However, one of the challenges of qualifying for workers compensation with asthma is to prove that you succumbed to the disease because of workplace exposure rather than from other environmental pollutants such as second-hand smoke.

What Causes Adults To Develop Asthma

What is nutrition’s role in developing asthma and allergies, & what role does food insecurity play?

At least 30% of adult asthma cases are triggered by allergies. People who are allergic to cats may have an increased risk for developing adult onset asthma. Exposure to allergens or irritants such as cigarette smoke, chemicals, mold, dust, or other substances commonly found in the persons environment might trigger the first asthma symptoms in an adult.

Prolonged exposure to certain workplace materials may set off asthma symptoms in adults.

Hormonal fluctuations in women may play a role in adult onset asthma. Some women first develop asthma symptoms during or after a pregnancy. Women going through menopause can develop asthma symptoms for the first time.

Different illnesses, viruses, or infections can be a factor in adult onset asthma. A bad cold or a bout with the flu is often a factor in adult onset asthma.

Smoking does not cause adult onset asthma; however, if you smoke or if you are exposed to cigarette smoke , it may provoke asthma symptoms.

What Are Signs And Symptoms Of Adult Onset Asthma

Regardless of age, asthma symptoms can include:

;;;;;;;;;;; Dry cough, especially at night or in response to specific triggers

;;;;;;;;;;; Tightness or pressure in the chest

;;;;;;;;;;; Wheezing a whistling sound when exhaling

;;;;;;;;;;; Shortness of breath after exercise or physical exertion

;;;;;;;;;;; Difficulty breathing

;;;;;;;;;;; Colds that go to the chest or hang on for 10 days or more

Asthma Symptoms Childhood Vs Adult

Childhood asthma symptoms are generally similar to adult asthma symptoms. However, determining asthma symptoms in children can be a bit more difficult. Adult asthma symptoms are easier to determine since an adult can tell you how they are feeling plus they know their body better. Although you can see and hear the coughing and shortness of breath in younger children, they may not be able to let you know how they are feeling. Plus young children are not able to do a breathing test called spirometry.

  • Not being able to keep up with other children while running around
  • Having a hard time catching their breath or breathing faster than other children who are doing the same thing
  • Looks like they have a cold, which could actually be asthma
  • Coughing, especially at night
  • Coughing so hard that they vomit
  • You may hear wheezing
  • If you notice any of these typical childhood asthma symptoms, see your doctor to find out if it is due to asthma.
