What Is The Prognosis For Asthma

How to prevent asthma attacks

The prognosis for asthma is generally favorable. Children experience complete remission more often than adults. Although adults with asthma experience a greater rate of loss in their lung function as compared to age-controlled counterparts, this decline is usually not as severe as seen in other conditions, such as chronic obstructive pulmonary disease or emphysema. Asthma in the absence of other comorbidities does not appear to shorten life expectancy. Risk factors for poor prognosis from asthma include

  • a history of hospitalizations, especially ICU admissions or intubation,
  • frequent reliance on systemic steroids,
  • significant medical comorbidities.

The airway narrowing in asthma may become fixed over time and can resemble COPD or emphysema. The other main complication of asthma is due to side effects from oral steroid use, which can include bone loss , weight gain, and glucose intolerance.

Know When To Get Help

Symptoms that place you in the “red zone” of your asthma action plan are serious. If you experience any of these, follow the instructions in your plan and get emergency care right away:

  • Wheezing when you inhale and exhale
  • Nonstop coughing

Immediately call 911 or your local emergency number if:

  • You can’t talk in full sentences.
  • Your lips or fingernails turn blue .
  • You begin breathing rapidly .
  • You aren’t able to breathe in or out fully.
  • You feel confused or agitated.
  • Your rescue inhaler doesn’t relieve your symptoms.

Create An Asthma Action Plan

For anyone who has asthma, an asthma action plan is essential for preventing symptoms that can progress to a full-on asthma attack. This is a written document you and your asthma doctor will develop together based on your asthma triggers, usual symptoms,;peak flow readings, and;what you should do at different stages of progressively worsening symptoms.

A typical asthma action plan uses the color coding of a traffic light and is divided into three zones.

;Green Your asthma is under control, your peak flow readings are within your healthy range, and you feel well.
;Yellow Your symptoms are worsening and/or your peak flow readings are declining.
;Red Your symptoms are dangerously severe and you should get emergency help right away.

In terms of prevention, the action plan will identify all of your known triggers and ways to avoid them. It also will list your medications and how you should be taking them.

Why Is Asthma An Important Public Health Issue

The negative impact on asthmatics from direct or second-hand smoke is significant.

The incidence of asthma has been increasing in the last few decades in the developed world,especially amongst children. Asthma is now a serious chronic condition in Ontario and in Canada.Asthma impacts the quality of life of those affected with the disease, as well as their families.According to the 1996-97 National Population Health Survey, more than 2.2 million Canadians hadbeen diagnosed with asthma by a physician at some time in their lives . The same survey found that approximately 10 per cent ofCanadian children and five per cent of adults had asthma at the time of the survey .

The prevalence of asthma in Canadian children aged 0-14 years increased from 141,000 childrenin 1978/79, to 167,000 children in 1983/84, and then to 672,000 children in 1994/95. This is adramatic increase from 2.5 per cent to 11.2 per cent of children under 14 years, over a periodof 18 years.

Asthma is also becoming more prevalent among low-income adults over the age of 35 years. It is notclear at this time whether that higher prevalence can be attributed to lifestyle , residential status, occupation or other factors.

Yet, despite these statistics, 35 per cent of people with asthma were regularly exposed to smoke inside their home. Thus, it is evident that a change in attitudes and behaviors around smoking is especially important for asthma sufferers.

Scuba Diving And Asthma

Discharge strategies to prevent asthma readmissions

Scuba diving if you have uncontrolled asthma can be life-threatening. In fact, it is one of the few sports that is not recommended for some people with asthma.;

The risk is that you may breathe in air at a certain pressure at a certain depth, then have that higher pressure air become trapped in your lungs due to asthma closing the air passages in your lungs. As you rise to the surface , that trapped air will expand and may cause injury to your lung. This is called barotrauma , and can be very dangerous.;

Only people with mild and well-controlled asthma should consider scuba diving and only with careful medical clearance. Diving regulations vary from country to country so if you have asthma and are keen to dive, its best to check on the local requirements and have a thoughtful discussion with your doctor.

Tips To Reduce Exposure To Pollen

The season for pollen allergies can last for several months and occurs when plants are flowering. The timing of your own personal allergy season will depend upon which plants you are allergic to, and when they flower.

A direct way to manage pollen allergies is to reduce your exposure to pollens. Pollen counts are published in the media and can help you to plan to avoid exposure.

To reduce your exposure to pollen during peak times:

  • Stay indoors in the morning, if possible grass pollens mainly circulate in the morning.
  • Avoid mowing the grass, or wear a mask when you mow if someone else is doing the mowing, stay indoors while they do so.
  • Keep windows closed in your home and car.
  • Avoid picnics in parks or in the country during the pollen season.
  • Wear sunglasses to protect your eyes.
  • Plant a low-allergy garden around your home, especially near the windows of your home.

How Is Asthma Diagnosed

A doctor visit is in order if you have asthma symptoms.

Asthma is diagnosed based on:

  • Your medical and family history of asthma and allergies
  • A physical exam
  • Asthma test results.

The doctor will use a stethoscope to listen to your lungs and look for signs of asthma such as wheezing, swollen nasal passages, and runny nose.

Asthma tests may include a lung function test called spirometry that measures how much and how fast you can blow air in and out. Your doctor might recommend allergy testing, too.

Invest In A Peak Air Flow Meter

A peak air flow meter can tell you how well youre able to breath out. Knowing the quality of your breath can help you predict when there is an impending asthma attack. This information can give you more time to initiate your asthma plan, control your symptoms, avoid the need for further medication, and potentially stop the attack before it starts.

When To Seek Medical Help

Preventing Asthma Attacks

  • Learn how to spot clues that mean you’re likely to have a flare-up.

    Asthma And Blood Oxygen Levels

    What causes blood oxygen levels to become low?

    Blood oxygen levels can get low due to any of the problems that include:

    • Low air oxygen levels: Atmospheric oxygen becomes extremely low at high altitudes such as mountainous regions.
    • Other conditions include anemia, sleep apnea, and smoking

    Asthma may not be the same in different affected individuals. Asthma specialists currently use a variety of clinical data to categorize a patient’s asthma. This data includes the age of asthma onset, the presence or absence of environmental allergies, the presence or absence of elevated blood or sputum levels of eosinophils , lung function testing , obesity, and cigarette smoke exposure.

    Types: T2 high or non T2

    Non T2 asthma, or T2 low asthma, comprises a smaller yet difficult to treat proportion of asthma that is not associated with allergies or eosinophils. This type of asthma is sometimes called “neutrophilic asthma” and may be associated with obesity.

    Treatment Options For Managing Cat Asthma

    There are two types of medications used to treat cat asthma: corticosteroids and bronchodilators.;Corticosteroids;are used daily to manage asthma. These medications help improve symptoms and prevent asthma attacks by reducing the inflammation in the lungs.

    If your cat is in distress ,;bronchodilators;help open the airways so they can breathe. Bronchodilators are often referred to as rescue medications because they provide quick relief and are only used when needed.

    Both of these medications are most effective when;administered by an inhaler;and a spacer device rather than taken orally or by injection. Inhaled medications directly target the lungs and significantly reduce the risk of side effects because they dont affect other organs in the body.

    Over-the-counter medications may be indicated under the direction of your vet, such as antihistamines, but are not to be used in place of corticosteroids and bronchodilators.
