Signs And Symptoms Of Bronchial Asthma In Acute Exacerbation

What Should I Do If I Have A Severe Asthma Attack

Asthma and COPD: Acute Exacerbations

If you have a severe asthma attack, you need to get immediate medical care.

The first thing you should do is use your rescue inhaler. A rescue inhaler uses fast-acting medicines to open up your airways. Its different than a maintenance inhaler, which you use every day. You should use the rescue inhaler when symptoms are bothering you and you can use it more frequently if your flare is severe.

If your rescue inhaler doesnt help or you dont have it with you, go to the emergency department if you have:

  • Anxiety or panic.
  • Bluish fingernails, bluish lips or gray or whitish lips or gums .
  • Chest pain or pressure.
  • Very quick or rapid breathing.

Whats The Outlook For People With Asthma

Most people with asthma are able to manage symptoms and maintain a good quality of life.

An acute exacerbation of asthma can be a life-threatening event. However, you should be able to resume your normal activities once its under control. Of course, youll want to avoid known triggers and follow your doctors advice for management of your asthma.

If you have asthma, you should have an action plan in place. Work with your doctor to come up with a plan so youll know what to do when symptoms flare up.

What Imaging Studies Will Be Helpful In Making Or Excluding The Diagnosis Of Asthma

Although the chest radiograph is usually of little specific diagnostic value in asthma, all patients with dyspnea or suspected asthma should have a chest radiograph performed on initial evaluation. The presence of infiltrates, consolidation, pleural effusions, or lung nodules should prompt consideration of alternative diagnoses. The chest radiograph can also be helpful in evaluating patients with severe or atypical forms of asthma, such as ABPA or chronic eosinophilic pneumonia.

In patients with poorly controlled asthma and a history of prior asthma exacerbations, the combination of budesonide and formoterol significantly reduces asthma exacerbations compared with ICS alone. ICS/LABA have consistently been shown to prevent exacerbations., , The benefit of ICS/LABA to prevent exacerbations versus ICS alone is primarily seen in patients requiring higher doses of ICS, thus suggesting that combination therapy to prevent exacerbations should be reserved for patients with more severe disease.

Asthma control can vary even in the face of ongoing ICS/LABA treatment. Consequently, the use of ICS/LABA combinations both for maintenance and symptom relief has been investigated and shown to reduce exacerbations., , These benefits are also seen in children with a prior history of severe asthma exacerbations and poorly controlled moderate-to-severe persistent asthma despite the use of moderate doses of ICS. The use of ICS/LABA as maintenance and reliever treatment should be restricted to formoterol because of its quick onset of action, safety profile, and dose-response effect.

Who Can Get Asthma

Asthma symptoms in children, adults, and more

Anyone can develop asthma at any age. People with allergies or people exposed to tobacco smoke are more likely to develop asthma. This includes secondhand smoke and thirdhand smoke .

Statistics show that people assigned female at birth tend to have asthma more than people assigned male at birth. Asthma affects Black people more frequently than other races.

What Causes Bronchial Asthma

The cause of bronchial asthma is not entirely known. There is also currently no way to prevent the condition. But researchers think a combination of genetic factors and environmental triggers may lead to bronchial asthma. For instance, if you have a parent who has bronchial asthma, you are more likely to develop the condition.

Having allergies or a family history of allergies also increases your risk. Additional risk factors include having frequent respiratory infections as a baby or young child, and smoking or being around secondhand smoke.

People who are obese or who were born prematurely also have an increased risk of developing bronchial asthma.

Globally, increasing patient population with various type of allergies, changing life style and environment pollution is increasing, which drives the global allergy treatment market. When the airways continue more sensitive, your child is more likely to have asthma symptoms when exposed to things that make asthma worse.

Another hydrotherapy solution is to add 16 ounces of hydrogen peroxide in a hot bath and soak for exacerbatoin to twenty minutes.

It is a vicious cycle that can lead to diabetes, high blood pressure, obesity, natural disorders, cardiac arrest and premature death. This category of asthma may be triggered by a person’s work environment elements.

Are You Sure Your Patient Has Asthma What Should You Expect To Find

No definitive test or specific symptom complex is diagnostic for asthma. In making an accurate diagnosis, the clinician should:

  • Determine whether the patient has episodic respiratory symptoms that occur as a result of exposure to an environmental trigger. Classic symptoms include cough, wheezing, dyspnea, and chest tightness.

  • Use pulmonary function testing to demonstrate the presence of airway obstruction that is at least partially reversible after bronchodilator administration.

  • Ensure that alternative diagnoses have been considered and excluded.

A diagnosis of asthma is often made based on the presence of symptoms alone, without appropriate consideration of alternative diagnoses and without pulmonary function testing. As a result, an erroneous diagnosis of asthma may be made, exposing the patient to unnecessary medications and risk.

A variety of asthma phenotypes are recognized, including allergic asthma, adult-onset asthma, steroid-resistant asthma, and exercise-induced asthma. Data also suggest that obesity and female sex can also affect the presentation of asthma. Consequently, entertaining a broad differential diagnosis and performing a thorough history are important when evaluating a patient for asthma. Not all patients will present with the classic history of episodic wheezing and environmental allergies.

Exacerbations And Accelerated Loss Of Lung Function

Asthmatic Bronchiole During an Exacerbation

A cycle of exacerbations and accelerated loss of lung function in asthma: Acute severe exacerbations in susceptible asthmatics activate pathways of inflammation and remodelling resulting in deterioration of lung function. Accelerated loss of lung function in turn puts these patients at increased risk of recurrent exacerbation resulting in a vicious cycle that may promote the exacerbationprone phenotype.

How And/or Why Did The Patient Develop Asthma

The etiology of asthma is unknown, but asthma likely results from complex interactions between multiple genetic and environmental variables. Studies of twins and families with asthmatic members have shown that, in many cases, asthma occurs in a pattern consistent with heritable factors. However, at present, the specific genes responsible for asthma have not been definitively identified. Furthermore, the variety of asthma phenotypes, as described previously, may have distinct etiologies, a focus of much ongoing research.

Management Of Patients Admitted To The Hospital: Wards And Icu Care

Careful consideration must be given to the level of care required when a patient with an exacerbation of asthma is admitted to the hospital. In general, guidelines suggest that patients should be admitted for observation and further treatment if the pretreatment FEV1 or PEF is < 25% of predicted or of personal best or if the post-treatment values are < 40% after emergency department treatment. Typically, patients who demonstrate a poor response to therapy , persistent or unresponsive hypercapnia, altered mental status, hypotension, or have significant comorbid conditions should be admitted to the ICU.

Although many patients maintain good oxygen saturations despite severe airway obstruction, some patients develop small airway mucus plugging even after the PEF/FEV1 normalize. Guidelines suggest that oxygen should be administered via nasal cannula or oronasal mask to maintain an arterial oxygen saturation of 9395% in adults and 9498% in children. In severe exacerbations, low-flow oxygen therapy by titrating the saturation to 9395% was associated with better physiological outcomes than with high-flow 100% oxygen therapy.

Home Management Of Asthma Exacerbations

An asthma exacerbation that causes minimal problems for the mother may have severe sequelae for the fetus. Patients should be instructed on rescue management and should be educated to recognize signs and symptoms of early asthma exacerbations such as coughing, chest tightness, dyspnea, or wheezing or by a 20% decrease in their PEFR. This is important so that prompt home rescue treatment may be instituted to avoid maternal and fetal hypoxia. In general, patients should use inhaled albuterol, 2 to 4 puffs every 20 minutes for up to 1 hour . The response is considered good if symptoms are resolved or if they become subjectively mild, normal activities can be resumed, and the PEFR is more than 80% of the personal best. For asthma exacerbations that can be managed at home, a course of oral prednisone is recommended, 40 to 60mg per day in a single dose or in two divided doses for 3 to 10 days.64 The patient should seek further medical attention if the response is incomplete or if fetal activity is decreased.

Nursing Interventions With Rationales For Bronchial Asthma Anxiety

Childhood bronchial asthma: acute exacerbation diagnosis and treatment ...
Nursing Interventions
Stay with the patient and encourage slow, deep breaths.Consistent presence and coaching can help lessen feelings of anxiety during an asthma exacerbation.
Provide a calm environment and decrease stimuli.A calm environment will decrease anxiety, thus decreasing oxygen consumption.
Educate the patient on pursed-lip breathing.Pursed lip breathing is an intentional breathing technique that encourages slow, deep, effective breaths.
Help the patient develop an emergency plan for asthma attacks.The patient should always have their rescue inhaler on hand. During an asthma exacerbation, the patient should sit upright and administer their rescue inhaler. If no relief is felt within 4 minutes, the patient should seek immediate medical attention, and continue administering the rescue inhaler every 4 minutes.

Induced Asthma Is A Chronic Inflammatory Pulmonary Disease That Affects The Bronchiole

Asthma is a chronic inflammatory pulmonary disease that affects the bronchiole. The air penetrate with more difficulty in the lungs because the swelling of the bronchiole.

The symptoms of asthma occur in episodes of asthma attack. This disease alternates free period with those of attacks.

An episode of asthma attack is determined by substances called triggers, substances presents in the external environment. For a healthy person these substances are harmless but for an asthmatic they cause severe symptoms like wheezing, difficulty breathing, coughing, dyspnoea, chest tightness.

The triggers are different for different persons. For example mole can cause an asthma attack to a person and be harmless for another asthmatic.

Exercise is another trigger that can induce asthma. It is usually a trigger for persons with a high sensitivity of the tracheobronchial tree. The mechanism trough exercise can induce asthma is not entirely known.

It is believed that the reaction of the tracheobronchial tree is a response to the differences of temperature and humidity between the air existing in the lungs and the air inhaled.

In a normal breath the air that arrives to the lungs is warmed and with a high humidity, because it is modified in the nasal mucous.

Classification Of Bronchial Asthma In Etiology

Distinguish allergic and non-allergic forms of the disease. At children in 90-95% of cases there is an allergic / atopic bronchial asthma. Non-allergic forms of asthma are referred to as non-allergic. The search for specific causal environmental factors is important for the designation of elimination activities and in certain situations allergen-specific immunotherapy.

Asthma Peak Week: How To Exercise Safely With Asthma

The third week of September is known as Asthma Peak Week, the week with the highest numbers of asthma attacks and hospitalizations every year. Allergen levels are at their highest this week, particularly common allergens like ragweed pollen, dust, and mold, and this can make any activity difficult. You might be reluctant to work out, but regular exercise can improve asthma symptoms by increasing lung capacity and reducing inflammation. A well-considered exercise plan guided by a medical professional is vital to ensuring you can exercise safely with asthma, so read on to learn what to discuss with your doctor about creating an exercise plan for you!

Nursing InterventionsRationales
Educate the patient about rescue inhalers vs. controller inhalers.Rescue inhalers are meant to be used in case of emergency and should not be used every day. Controller or maintenance inhalers can be used every day to decrease symptoms of asthma. Examples of maintenance inhalers are Symbicort and Advair.
Educate the patient about environmental asthma triggers.Examples of environmental triggers include smoke, allergens, mold, and air pollution.
Educate the patient on how to effectively manage asthma when exercising.Sometimes asthma can be exacerbated by exercise. Walking, swimming, or hiking are asthma-friendly alternatives, and exercise with short bursts of activity is better than prolonged exercise. Sometimes a physician can prescribe a rescue inhaler to be used before exercise.
Show the patient how to use a spacer.A spacer is a tube between the inhaler and the patients mouth which gives the patient more time to inhale the medication.
Advise the patient to rinse their mouth following administration of an inhaled corticosteroid.If the mouth is not properly rinsed after administration of inhaled corticosteroids the patient can develop thrush, a fungal infection in the mouth, which looks like white patches on the mucous membranes and tongue.

  • Atopic eczema, asthma and hay fever tend to run together in individuals and in families.
  • Ask about medication the patient may have been started on a beta-blocker recently or taken anti-inflammatory drugs. The association between non-steroidal anti-inflammatory drugs , including aspirin, and the precipitation of asthma is well documented but, in reality, it is not often seen.
  • Ask about smoking, including passive smoking.

Testing For Severe Asthma

Before you can be tested for severe asthma, you will need a referral from your primary healthcare asthma provider to either an asthma specialist or allergy specialist . The specialist will review your medical history, your current asthma treatment plan and do a physical exam to assess your symptoms. If the specialist thinks you may have severe asthma, they will discuss additional testing with you to determine your specific type. This often starts with testing to identify a biomarker.

Biomarkers help determine what is causing the inflammation in your airways. Taking a blood sample, analyzing a mucus sample or taking a breathing test that measure substances in your breath droplets are all common tests doctors use. These tests are performed in a doctors office or an outpatient clinic setting. Your specialist will recommend one or more of these tests based on your medical history and current symptoms. Once the biomarkers are identified, your doctor can determine the type of severe asthma and the different treatment options that are available to treat that specific type.

Mechanisms Of Asthma Exacerbation

Asthma exacerbations represent acute-on-chronic worsening of airflow obstruction that is a consequence of worsening airway smooth muscle contraction, airway wall edema, and luminal obstruction with mucus.238 The mucus pathology is especially problematic in fatal and near fatal asthma . Common upper respiratory tract viruses, especially rhinoviruses, are the most common and important cause of exacerbations in both children and adults.239,240 Susceptibility to acute reductions in airflow in asthmatics relates to airway mucosal remodeling. Changes in the epithelium to increase mucin stores, in airway smooth muscle to render it more hyperreactive, and in blood vessels to make them leakier render many asthmatics vulnerable to exaggerated airway responses to inhaled environmental insults, such as viruses, allergens, or pollutants.238 Asthmatic airways are hyperreactive in more ways than oneconcentric smooth muscle contraction from hyperresponsiveness is one element, but mucosal edema from vascular permeability and excess mucus from mucin hypersecretion are others. The efficacy of corticosteroids in preventing exacerbations likely relates to their effects in not only reducing inflammatory cell numbers but also improving pathologic changes in goblet cells, smooth muscle cells, and blood vessels.

How Do You Monitor Asthma Symptoms

Asthma Exacerbation Definition

You should keep track of your asthma symptom. Its an important piece of managing the disease. Your healthcare provider may ask to use a peak flow meter. This device measures how fast you can blow air out of your lungs. It can help your provider make adjustments to your medication. It also tells you if your symptoms are getting worse.

Acute Exacerbations Of Chronic Obstructive Pulmonary Disease

Similar to asthma exacerbations, most AECOPDs are caused by common respiratory viruses . Because vitamin D-mediated immune mechanisms appear to play a role in the prevention of viral ARI, vitamin D supplementation might be helpful against AECOPD. However, AECOPD is a more complicated phenomenon than asthma exacerbation. For starters, AECOPD often involve both viruses and bacteria . Moreover, the typical COPD patient is older and more likely to suffer from other relevant smoking-related comorbidities, such as cardiovascular disease . Nevertheless, the question remains: does vitamin D supplementation lower the risk of AECOPD?

In 2012, Kunisaki and colleagues analyzed data from an azithromycin trial of exacerbation-prone patients with COPD to examine the longitudinal association between baseline 25D levels and risk of AECOPD over 1 year . Contrary to their hypothesis, baseline 25D levels were unrelated to risk of AECOPD in their observational study of this high-risk population. Similarly null findings were reported in a 2014 study by Puhan and colleagues from the Netherlands and Switzerland and in the previously cited 2015 study by Persson and colleagues in Norway . Taken together, these observational studies do not support a role for vitamin D supplementation in the prevention of AECOPD.
