Chapter 29 Assessment of the Respiratory System
Anatomy and Physiology Review • Upper respiratory tract • Lower respiratory tract • Lungs • Accessory muscles of respiration • Respiratory changes associated with aging
Patient History • Collect history of patient data on family, personal, smoking, drug use, allergies, travel, place of residence, dietary history, occupational history, and socioeconomic level. • Pack-years of smoking—number of packs smoked per day multiplied by the number of years the patient has smoked. • Assess current health problems such as cough, sputum production, chest pain, and dyspnea.
Patient History (Cont’d) • Drug use • Allergies • Travel and geographic area of residence • Nutritional status • Cough, sputum production, chest pain, dyspnea, PND, orthopnea
Physical Assessment • Assessment of the nose and sinuses
Physical Assessment (Cont’d) • Assessment of the pharynx, trachea, and larynx
Physical Assessment (Cont’d) • Assessment of the lungs and thorax
Physical Assessment (Cont’d) • Assessment of the lungs and thorax
Other Indicators of Respiratory Adequacy • Clubbing • Weight loss • Unevenly developed muscles • Skin and mucous membrane changes • General appearance • Endurance
Psychosocial Assessment • Some respiratory problems may be worsened by stress. • Chronic respiratory disease may cause changes in family roles, social isolation, and financial problems due to unemployment or disability. • Discuss coping mechanisms and offer access to support systems.
Laboratory Tests • Blood tests • Sputum tests • Radiographic examinations including standard chest x-rays, digital chest radiography, CT • Ventilation and perfusion scanning • Pulse oximetry
Pulmonary Function Testing • These tests evaluate lung volumes and capacities, flow rates, diffusion capacity, gas exchange, airway resistance, and distribution of ventilation. • Patient preparation. • Procedure for performing tests at the bedside.
Other Testing and Follow-Up Care • Exercise testing • Skin testing
Other Invasive Diagnostic Tests • Endoscopic examinations • Thoracentesis—aspiration of pleural fluid or air from the pleural space: • Patient preparation for stinging sensation and feeling of pressure • Correct position • Motionless patient • Follow-up assessment for complications
Lung Biopsy • Performed to obtain tissue for histologic analysis, culture, or cytologic examination. • Patient preparation. • May be performed in patient’s room.
Lung Biopsy(Cont’d) • Follow-up care: • Assess vital signs and breath sounds at least every 4 hr for 24 hr. • Assess for respiratory distress. • Report reduced or absent breath sounds immediately. • Monitor for hemoptysis.
