Chest Exam / Lung Topography Physical examination employs the use of inspection, palpation, percussion, and auscultation to determine patients’ clinical status and their response to therapy Each examination is modified according to the purpose of the examination Physical examination skills develop over time with practice Examination of the Head and Neck Identify the patient’s facial expression, looking for evidence of pain or acute distress Look for evidence of cyanosis around the lips and oral mucosa Patients may use pursed-lip breathing when COPD is present Eyes The eyes are inspected for pupillary response to light when neurologic defects are suspected Dilated and fixed pupils suggest brain death in some patients The eyelids may droop (ptosis), indicating damage to the third cranial nerve Neck The trachea should be midline If it is deviated to one side, a unilateral lung problem is probably present The status of the jugular veins in the neck is important Atelectasis pneumothorax Patients with cor pulmonale have JVD Use of accessory muscles in the neck suggests obstructive lung disease Lung Topography Anterior chest is defined by the midsternal and midclavicular lines Lung Topography Lateral chest is defined by midaxillary, anterior axillary and posterior axillary lines Lung Topography Posterior chest is defined by the midspinal and midscapular lines Thoracic Cage Landmarks Thoracic Cage Landmarks On the posterior chest, C7 is seen as the most prominent spinous process at the base of the neck Thoracic Cage Landmarks The angle of Louis, or sternal angle, is located on the anterior chest. Formed by the ridge between the manubrium and the gladiolus Lung Fissures The oblique fissure starts at rib six on the anterior chest at the midclavicular line It runs up and laterally crosses the midaxillary line at fifth rib and across the posterior chest, ending at T3 horizontal fissure passes from the fourth rib at the midsternal line laterally to the fifth rib in the midaxillary line Tracheal Bifurcation At T4 on posterior chest At sternal angle on anterior chest Tracheal Bifurcation Diaphragm The diaphragm is a dome-shaped muscle The top of the dome rests at about the fifth rib anteriorly and at T9 on the posterior chest normally Lung Borders On the anterior chest the upper border of the lung extends 2 to 4 cm above the medial third of the clavicles. The inferior border of the lung is at rib six normally Lung Borders On the lateral chest the lower margin of the lung is at rib eight Lung Borders On the posterior chest the superior border of the lung extends to T1. The inferior border varies with breathing but is usually at about T10 Examination of the Thorax Look Feel Listen Look For A barrel chest or evaluate the A-P diameter An in crease A-P diameter is consistent with COPD Look For Kyphoscoliosis is present when the spine is bent laterally and from front to back Can causea restrictive lung problem Look For Pectus carinatum is seen as an abnormal sternal protrusion Look For Pectus excavatum is seen as depression of the sternum Look For Breathing pattern is important to identify when lung disease is present Rapid and shallow breathing is consistent with restrictive disease A prolonged expiratory time is consistent with obstructive lung disease Retractions are seen as inward depression of the skin around the rib cage with inspiration Abdominal paradox is seen as inward movement of the abdomen with inspiration This suggests a high work of breathing (WOB) This suggests diaphragm paralysis or fatigue Hoover’s sign is seen as inward movement of the lateral chest with inspiration. It is a sign of severe COPD. Feel For (Palpation) Vocal fremitus is assessed to identify pathologic changes in the lung. Increased vocal fremitus is consistent with pneumonia and atelectasis. Decreased vocal fremitus is consistent with lung hyperinflation, pleural disorders, and obesity. Palpation Palpation Use palpation to assess for uniform chest excursion Percussion Percussion is done to determine the condition of the underlying lung. Increased resonance is heard with pneumothorax and lung hyperinflation. Decreased resonance is heard with pneumonia and atelectasis.
