Asthma attack symptoms
Asthma is a chronic respiratory disease that causes inflammation of the airways (bronchi). This leads to a narrowing and swelling of the airways, causing difficulty breathing. The causes of asthma are associated with genetic, chemical and environmental. Some common triggers for asthma are infections such as colds and flu, drug allergies, pollen, dust mites, food allergies, irritants like cigarette smoke or dust and some chemicals. Asthma can also be caused by some exercises in the cold, dry air. When a person is exposed to one of the factors that lead, histamine and other agents are released by the body. This can cause inflammation of the airways, causing airway narrowing and clogging. It can lead to symptoms such as breathlessness, coughing, wheezing and chest tightness. Approximately 20.5 million people in the United States are diagnosed with asthma.
What is asthma?
Asthma attack or exacerbation of asthma is caused by swelling and inflammation of the airways. airway narrowing is caused by inflammation, hyperresponsiveness and bronchospasm. airway inflammation resulting from exposure to allergens or irritants or action of chemical mediators such as histamine. Inflamed tissues produce a thick mucus, sticky, which can cause airway obstruction. This mucus may accumulate in the lungs, causing difficulty breathing. The muscles are tight wrapped around the airways, causing airway constriction. chronic inflammation of the airways become highly sensitive to allergens or irritants. This condition is known as bronchial hyper-responsiveness "that. Asthma attacks are triggered by an infection of upper respiratory disease gastroesophageal reflux disease (GERD), inhalation of cold dry air and allergens, such as some pets, pollen, dust mites, mold and tobacco smoke.
Symptoms of asthma
During an acute asthma attack, a series of changes occur in the lungs and airways, which contribute to develop signs and symptoms of asthma. Inflammation, excess production of mucus and bronchospasm can cause various signs and symptoms of asthma, such as breathlessness, wheezing and coughing. Symptoms of an asthma attack can vary in severity and duration from person to person. The warning signs of an asthma attack include headache, chronic cough, throat irritation, difficulty speaking, difficulty sleeping, difficulty breathing, chest tightness and wheezing. Wheezing is a symptom frequently observed in asthma. This is a whistling or hissing sound that comes with breathing. Wheezing is usually heard at the end, however, it may also occur during inhalation. When the first signs of an asthma attack are detected, then you should seek immediate medical treatment to prevent severe attacks of asthma. mild asthma are more commonly observed and can be cured in a few hours after treatment.
Severe asthma attacks are less frequent. However, they can last for a longer duration and requires immediate medical treatment. Symptoms severe asthma develop gradually and can become severe in 6-48 hours. There are signs of worsening asthma severity. These signs include a low peak flow expiratory (PEF), increased pulse, increased wheezing, fatigue and anxiety.
In cases of severe asthma attack can not be life-threatening symptoms. Some typical symptoms of severe asthma attack are shortness of breath, difficulty speaking, nasal flaring, pulse rate or heart rate, chest pain, sweating and reading the peak flow in the red zone. Silent chest is an important sign of severe asthma. There is no wheezing at inspiration and expiration. There may be some symptoms of cyanosis, such as gray or bluish skin, lips and nails. Maybe there is a feeling of anxiety, reduced alertness, severe drowsiness or confusion during the attack of severe asthma. A severe asthma attack can cause respiratory arrest and death. Asthma is considered a medical emergency that requires immediate medical attention.
Treatment of asthma
Symptoms of asthma may resemble other respiratory problems such as respiratory tract infections, bronchitis and emphysema. Therefore, an accurate diagnosis of asthma is very essential to decide the appropriate treatment option. The severity of asthma symptoms are controlled by pulmonary function tests such as peak flow readings, spirometry, pulse oximetry measurement of nitrous oxide. asthma treatment focuses on managing symptoms, maintaining normal lung function and prevent severe attacks of asthma. Some medications such as beta-agonists for short-term oral corticosteroids, leukotriene inhibitors such as zileuton and montelukast and methylxanthines can be used to reduce inflammation in acute asthma attack. The use of inhaled HFA (hydrofluoroalkane) can help control symptoms of breathlessness. If symptoms of asthma attack is life threatening, then intubation and mechanical ventilation become necessary to help him breathe.
The best way to prevent an asthma attack is to avoid contact with triggering factors. You must identify allergy triggers and avoid them as much as possible exposure. With appropriate medical treatment, nutritious diet and a healthy lifestyle can prevent these distressing symptoms of asthma.
