Chapter 27: Concepts of Care for Patients With Noninfectious Lower Respiratory Problems

The content spans multiple chronic conditions including asthma, which involves airway inflammation and hyperresponsiveness leading to reversible airflow obstruction managed through controller and rescue medications alongside patient education on inhaler technique and personal triggers. Chronic obstructive pulmonary disease represents a progressive airway disease combining emphysematous and bronchitic components that impair expiratory flow, requiring comprehensive management strategies such as smoking cessation counseling, pharmacological therapy, oxygen supplementation, breathing rehabilitation techniques, and pulmonary exercise programs to maintain functional capacity. Cystic fibrosis, a genetic disorder affecting the cystic fibrosis transmembrane conductance regulator protein, results in abnormally thick secretions throughout multiple organ systems and demonstrates how emerging targeted therapies and modulator medications are transforming disease outcomes. Pulmonary arterial hypertension is examined as a vascular pathology that elevates pressure within pulmonary circulation, increasing right ventricular strain and requiring vasodilator therapies including prostacyclin agents and guanylate cyclase activators alongside infection prevention protocols. Idiopathic pulmonary fibrosis involves progressive alveolar fibrosis that gradually reduces gas exchange capacity, managed through antifibrotic pharmacotherapy and supportive oxygen therapy. Lung cancer concludes the chapter through discussion of etiology, risk factors, genetic mutations, and multimodal treatment approaches encompassing surgical resection, chemotherapy, targeted molecular therapy, and immunotherapeutic strategies. Throughout all conditions, the chapter emphasizes interprofessional collaborative approaches, patient-centered education, symptom management, activity pacing, medication adherence, and psychosocial support to optimize respiratory function and quality of life.
