Criteria for exacerbation severity are based on symptoms and physical examination parameters, as well as lung function and oxygen saturation. Multiple doses of inhaled anticholinergic medication combined with beta2 agonists improve lung function and decrease hospitalization in school-age children with severe asthma exacerbations. The administration of systemic corticosteroids within one hour of emergency department presentation decreases the need for hospitalization, with the most pronounced effect in patients with severe exacerbations. Airway inflammation can persist for days to weeks after an acute attack; therefore, more intensive treatment should be continued after discharge until symptoms and peak expiratory flow return to 2005, the prevalence of asthma in the united states was nearly 8 percent (close to 9 percent in children younger than 18 years), and approximately 4 percent of americans (5 percent of children) experienced an asthma attack. 2 there have been many advances in medical therapy to prevent the worsening of asthma symptoms, including an improved understanding of asthma etiology, identification of risk factors for asthma exacerbations, and evidence supporting the benefits of written asthma action study of children up to 18 years of age presenting to the emergency department with acute asthma symptoms identified multiple risk factors for a subsequent emergency department visit: age younger than two years, black race or hispanic ethnicity, persistent asthma, public health insurance, lower asthma quality-of-life scores, and increased use of the health care system during the previous 12 months.
In adults, variables associated with relapse within eight weeks of an asthma exacerbation include three or more visits for emergent care in the preceding six months, difficulty performing daily activities because of physical health in the preceding four weeks, and patient self-discharge from care within 24 hours of hospital admission without achieving 50 percent predicted peak expiratory flow (pef). Persons older than two years with asthma, neither the injectable nor the intranasal influenza vaccine increases the likelihood of an asthma exacerbation in the period immediately following vaccination. Although no single parameter has been identified to assess exacerbation severity, lung function is a useful method of assessment, with a pef of 40 percent or less of predicted function indicating a severe attack in patients five years or older. The most useful signs for determining the severity of an asthma exacerbation in children younger than five years, or any child unable to perform a pef, include the use of accessory muscles of respiration, chest wall retractions, tachypnea greater than 60 breaths per minute, cyanosis, and the presence of inspiratory and expiratory wheezing. Patients who have a written asthma action plan and appropriate medication can often manage mild exacerbations at home (figure 16). Key components of an asthma action plan that have reduced emergency department visits and hospitalization include standard written instructions; criteria based on symptoms or pef (compared with personal best) to trigger action; two to three action points; and individualized, written instructions on the use of inhaled or oral corticosteroids. Patients at risk of asthma-related death may need more intensive treatment in a monitored setting at the first sign of an exacerbation (table 26).
These patients should have an asthma action plan that emphasizes early communication with their physician.

Asthma affects children and adults, causing excess mucus and swelling of the airways, affecting airflow. In an acute asthma attack, symptoms are exacerbated and people develop increasing shortness of breath, cough, wheezing and tightness in the chest. Many asthma exacerbations can be prevented with daily controller medications and lifestyle changes, but sometimes triggers can cause the asthma to flare ms of asthma exacerbation may include feeling restless, coughing, wheezing and chest tightness. Things a doctor may consider to determine how bad an exacerbation is and how it will be treated include: how much the respiratory rate is increased; speed of heart rate; ability to take deep breaths and inflate the lungs; blood oxygen levels; whether the patient is using extra muscles to breathe; whether the patient can talk in full sentencesa person with a mild asthma exacerbation may just feel short of breath and mildly restless, but may not have any significant change in oxygen level. On the other hand, in a life-threatening exacerbation, a person may be agitated, unable to speak, using abdominal muscles to breathe and have a blue tinge to his lips from poor oxygen levels in the asthma exacerbation is often caused by a particular trigger. Respiratory viruses, especially rhinovirus, cause the majority of asthma exacerbations in both children and adults. Medications not related to asthma treatment may still have the effect of triggering an asthma attack.
Aspirin, anti-inflammatory pain medications, and blood pressure medications known as beta-blockers and ace inhibitors may all interfere with asthma control. Stopping or changing an asthma control medication can also lead to asthma becoming unstable and spiraling into an attack. Being male, having a strong family history of severe asthma, and having eczema or allergies may translate to greater risk of ents vary depending on severity of the attack. When an attack starts, home treatment with rescue bronchodilators is important to try to stop exacerbation. Magnesium sulfate is a naturally occurring mineral in the body, and when given intravenously it has been found to help stop severe asthma you have asthma and are suffering from shortness of breath and wheezing despite taking your control and rescue medications, seek immediate medical attention. Consequences of an untreated asthma attack could be dire, including confusion, poor organ function, collapse of the respiratory system and even death. Call 911 if you are suffering from an asthma attack that is severe or you see someone with asthma who is struggling to breathe, is in distress, or turning pale or weight.
