APPROACH TO THE DIAGNOSIS OF DYSPNEA Pulmonary dyspnea DR.Hatice Türker Sureyyapasa Chest Diseases and Thoracic Surgery education and Research Hospital , Istanbul, TTD 15.ANNUAL CONGRESS /ANTALYA 13-04-2012
PLAN Pulmonary Dyspnea Definition Mechanisms Causes of dyspnea Assesment Differential diagnosis Therapy
Dyspnea-increased effort of breathing ‘’Dyspnea’’ Dys:difficult, painful Pneumea:breath
DEFINITION OF DYSPNEA • Patients perceptions: • Unsatisfied inspiration • Chest tightness • Sensation of feeling breathless • Cannot get enough air • Hunger for air • Incomplete exhalation
DEFINITION OF DYSPNEA DEFINITION OF DYSPNEA Clinical :A subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity. Physiological: The stimulation of pulmonary and extrapulmonary afferent receptors and the transmission of afferent information to the serebral kortex,where the sensation is perceived as uncomfortable or unpleasant Am Respir Crit Care Med.Vol 159,1999 Am Respir Crit Care Med. Vol 185,2012
SUBSTANTIAL EVIDENCE 1-Distinct mechanisms and afferent pathways are reliably associated with different sensory qualities (notably work/effort, tightness, and air hunger/ unsatisfied inspiration) 2-Distinct sensations most often do not occur in isolation 3-Dyspnea sensations also vary in their unpleasantness and in their emotional and behavioral significance. Dyspnea per se can only be perceived by the person experiencing it. Adequate assesment of dyspnea depends on self-report. Am Respir Crit Care Med. Vol 185,2012

QUALITIES OF DYSPNEA Arise through cortical motor command Work/effort Stimulation of airway receptors Tightness Imbalance when ventilation increases Hunger for air Am Respir Crit Care Med. Vol 185,2012
ASSESMENT OF DYSPNEA • History • Work/effort • Acute dyspnea • Chronic dyspnea • Associated symptoms • Positionaldyspnea
Anamnesis Work/effort Acute dyspnea Chronic dyspnea Associated symptoms Positionaldyspnea CHARACTERISTICS OF HISTORY Persistance among the day and year and variability Causes triggering or augmenting dyspnea What are the associated symptoms? What is the relationship with position?
CHARACTERISTICS OF HISTORY • Persistance among the day and year and variability • Intermittent • Persistent • Nocturnal • Seasonal • Occupational ( work,home ...etc.)
CHARACTERISTICS OF HISTORY • Intermittent dyspnea • Reversibl causes • Acute bronchoconstriction • Congestive heart failure • Acute pulmonary embolism • Pleural effusion • Persistent dyspnea • Irreversibl causes • COPD • Interstitial • Chronicpulmonary embolism • PAH • Diaphragmatic dysfunction • Chest wall disorders
Anamnesis Work/effort Acute dyspnea Chronic dyspnea Associated symptoms Positionaldyspnea CHARACTERISTICS OF HISTORY • Nocturnal dyspnea • Asthma • Congestive heart failure • Gastroesophageal reflux • Sleep-apnea syndrome • Nasal obstructions

MODIFIED BORG SCALE Borg, 1982 Verbal expression of degree of dyspnea in a nonlinear and numericalway, It’s easier to apply with exercise, It’s appropiate for comparison of persons or groups.
MODIFIED BORG SCALE Score Symptoms
VISUAL ANALOG SCALE What can you do today? Everything Nothing How severe is your dyspnea today? Very difficult None How severe is your dyspnea while dressing today? Very severe No dyspnea 0 cm 10 cm
OXYGEN COST DIAGRAM It’s a vertical visual analog scale with 13 items designed for assessment of oxygen need during sleep and walking uphill.
Brisk walking uphill medium walking uphill Brisk walking on the level Slow walking uphill Medium walking Bed-making Slow walking on the level Standing Washing yourself Sitting Sleeping 0 OXYGEN COST DIAGRAM
BASALINE DYSPNEA INDEX It’s a versatile scale Functional disability (daytime activities and work performance) Intensity and difficulty of the physical activity Grade of effort Total BDI score: 0-12 Low scores show that dyspnea is severe Mahler DA, Chest 1984;85:751-58
Anamnesis Work/effort Acute dyspnea Chronic dyspnea Associated symptoms Positionaldyspnea ACUTE VE CHRONİC DYSPNEA Acute: dyspnea that develops over hours or days. Chronic: dyspnea that develops over weeks,months or years.

TREATMENT OF DYSPNEA Am Respir Crit Care Med. Vol 185,2012
PHARMACOLOGICAL TREATMENT Opioids have been the most widely used. Short-term administration reduces breatlessness. Long-term efficacy is limited and conflicting. Associated with frequent side effects (constipation) Respiratory depression is uncommon with the doses used to treat dyspnea, even in elderly patients
PHARMACOLOGICAL TREATMENT Nebulized furosemide has been investigated as a novel pharmacologic approach. The mechanism of the effect is uncertain. Decreased breatlessness induced in normal volanteers. Currently insufficient data to support its use in the treatment of dyspnea.
PHARMACOLOGICAL TREATMENT Anxiolytics Antidepressants Fhenothiazines Indomethacin Inhaled topical anesthetics Nitrous oxide Sodium bicarbonate INEFFECTIVE Can Respir J 2011;18:69-78 Cochrane Databasa Syst Rev 2010; Thorax 2008;63:872-875
PULMONARY REHABILITATION Integral component of the management of patients with chronic lung disease. Decreases dyspnea during exercise Improved exercise tolerance Inspiratory muscle training (IMT) reduces of dyspnea intensity and dynamic hyperinflation
