ASTHMA2AsthmaThe purpose of this paper is to detail the pathophysiology of chronic and acute asthma. This paper will also explain patient factors that increase a patient’s risk of asthma or predisposition to such an illness. This article will detail the symptoms of, diagnosis and treatments related to acute and chronic asthma. Asthma is incurable, but symptoms can be managed as noted by ("Asthma," 2016). Acute AsthmaAsthma according to (Huether & McCance, 2012, p. 689), is an inflammatory disorder of the bronchial mucosa that causes hyper responsiveness and constriction of the airways. With asthma, there is persistent inflammation of the bronchial mucosa and hyper-responsiveness of the airways. The response to this inflammation is histamine production, this causes vasodilation, increased permeability, mucosal edema and bronchial spasms leading to narrowing of the airways and obstruction of airways, as noted by (Huether & McCance, 2012, p. 689). If this inflammation is left untreated it may lead to long-term airway constriction that is irreversible, known as airway remodeling. The airway constriction or obstruction lead to airflow resistance causing expiratory wheezing, and trapping of air. Air entrapment causes hyperventilation that is triggered by receptors response to the lung volume, which leads to hypoxemia. This hypoxemia causes air retention and respiratory acidosis, and ultimately respiratory failure, as noted by (Huether & McCance, 2012). Chronic AsthmaChronic Asthmatics often have normal pulmonary function and remain asymptomatic when not having an attack. When an attack begins, they may experience chest constriction, expiratory wheezing, dyspnea, nonproductive cough, tachycardia and tachypnea as noted by,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
