Pathophysiology Of Asthma
Wendy,
I think your description of the pathophysiology of asthma was right on point. Due to the release of the mediators causing an increase in blood flow and vasoconstriction, which is why his BP increased and experiencing tachycardia. With bronchoconstriction, causing him to used excessive muscle to breathing, leading him to have tachypnea of 42 with shallow breathing.
Since the patient is experiencing exacerbating, it is important to act quickly and manage it by early treatment and education. There should be a written action plan as part of any overall effort to educate patients about self-management techniques, especially when it comes with moderate to severe persistent asthma or with a history of severe exacerbation. When it comes to
treatment, quick-acting beta2-adrengic agonist medication are the first for prompt relief of airflow and obstruction (Hinkle & Cheever, 2014). One of the common used of beta2-adrengic agonist is albuterol sulfate. When giving this medication, it is important to educate the patient on the side effects of it such as, tremor, CNS stimulation, malaise, dry and irritated nose and throat with inhaled form, and hypokalemia. If patient's is given tablets or aerosol together, nurses should monitor the patient closely for signs and symptoms of toxicity. With beta2-adrengic agonist, it can also cause potassium level to decrease, so nurses should also educate the patient on increase potassium e.g banana, potato, avocado, and/or potassium supplement if needed (Hallowell & Comerford, 2014).
