Asthma Complications of asthma can be sudden. Consider the case of Bradley Wilson, a young boy who had several medical conditions. He appeared in good health when he went to school, returned home, and ate dinner.

Asthma pathophysiology essay

How to Write a Summary of an Article? Angela Marie Ferrer BSN 3B July 17, Definition A condition of the lungs characterized by widespread narrowing of the airways due to spasm of the smooth muscle, edema of the mucosa, and the presence of mucus in the lumen of the bronchi and bronchioles.

Asthma pathophysiology essay

Bronchial asthma is a chronic relapsing inflammatory disorder with increased responsiveness of tracheobroncheal tree to various stimuli, resulting in paroxysmal contraction of bronchial airways which changes in severity over short periods of time, either spontaneously or under treatment.

Causes Allergy is the strongest predisposing factor for asthma. Common triggers of asthma symptoms and exacerbations include air way irritants like air pollutant, cold, heat, weather changes, strong odors and perfumes.

Other contributing factor would include exercise, stress or emotional upset, sinusitis with post nasal drip, medications and viral respiratory tract infections.

Defining Asthma

Asthma pathophysiology essay people who have asthma are sensitive to a variety of triggers. Factors that can contribute to asthma or airway hyperreactivity may include any of the following: House dust mites, animal allergens especially cat and dogcockroach allergens, and fungi are most commonly reported.

Based on a prospective cohort study of 86, patients, those with an elevated body mass index are more likely to have asthma. In some instances cough may be the only symptoms. An asthma attack often occurs at night or early in the morning, possibly because circadian variations that influence airway receptors thresholds.

An asthma exacerbation may begin abruptly but most frequently is preceded by increasing symptoms over the previous few days. There is cough, with or without mucus production. At times the mucus is so tightly wedged in the narrow airway that the patient cannot cough it up.

Prevention Patient with recurrent asthma should undergo test to identify the substance that participate the symptoms. Patients are instructed to avoid the causative agents whenever possible.

Knowledge is the key to quality asthma care. Medical Management There are two general process of asthma medication: Because of underlying pathology of asthma is inflammation, control of persistent asthma is accomplish primarily with the regular use of anti inflammatory medications.

They are broadly effective in alleviating symptoms, improving air way functions, and decreasing peak flow variability.

Other sample model essays:

Cromolyn sodium and nedocromil are mild to be moderate anti-inflammatory agents that are use more commonly in children. They also are effective on a prophylactic basis to prevent exercise-induced asthma or unavoidable exposure to known triggers.

These medications are contraindicated in acute asthma exacerbation. They have the rapid onset of acton. Anti-cholinergic may have an added benefit in severe exacerbations of asthma but they are use more frequently in COPD. Nursing Management The main focus of nursing management is to actively assess the air way and the patient response to treatment.

The immediate nursing care of patient with asthma depends on the severity of the symptoms. The lower respiratory tract consist of the bronchi, bronchioles and the lungs. The major function of the respiratory system is to deliver oxygen to arterial blood and remove carbon dioxide from venous blood, a process known as gas exchange.

The normal gas exchange depends on three process: This is accomplished through the mechanical acts of inspiration and expiration. Control of gas exchange — involves neural and chemical process The neural system, composed of three parts located in the pons, medulla and spinal cord, coordinates respiratory rhythm and regulates the depth of respirations The chemical processes perform several vital functions such as: The normal functions of respiration O2 and CO2 tension and chemoreceptors are similar in children and adults.

The presence of inspiratory wheezing or stridor may prompt an evaluation for an upper airway obstruction such as vocal cord dysfunction, vocal cord paralysis, thyroid enlargement, or a soft tissue mass eg, malignant tumor.

Bronchoprovocation testing helps determine if airway hyperreactivity is present, and a negative test result usually excludes the diagnosis of asthma. It can be used for short-term monitoring, exacerbation management, and daily long-term monitoring.

CBC is ordered to aid in the detection of anemias; hydration status; and as part of routine hospital admission test. The differential WBC is necessary for determining the type of infection.

Lymphocytes are decreased during early acute bacterial infection and only increase late in bacterial infections but continue to function during the chronic phase.

Pathophysiology of Asthma - Essay. Topics: Asthma, Pathophysiology of Asthma Asthma is a chronic lung disease characterized by episodes in which the bronchioles constrict due to oversensitivity. In asthma, the airways (bronchioles) constrict making it difficult to get air in or out of the lungs.

Breathlessness is the main symptom. It causes repeated episodes of wheezing, breathlessness, chest tightness, and nighttime or early morning coughing. It is with you all the time, but you may have asthma attacks only when something bothers your lungs. Asthma is a common and well known ailment affecting the respiratory tract which is characterized by airway hyper-responsiveness to a multitude of stimuli.

Pathophysiology focuses on how certain conditions (like asthma) develop, so it is discovering the roots of illnesses. That’s why it is so important! Without researches in this field, it would be almost impossible to cure diseases quicker and more effectively.
