FUNDAMENTALS OF PHYSICAL EXAMINATION Chapter 5 EXAMINATION OF THE HEAD AND NECK FACIAL EXPRESSION Identify patient’s facial expression Acute distress Pain Alertness, mood, mental capacity  Signs of Respiratory Disease: Nasal flaring NASAL Flaring of the nares during inspiration Suggests an increased WOB is present FLARING AND Cyanosis Bluish discoloration of the skin CYANOSIS Only apparent when a significant amount of deoxygenated Hb is present NASAL FLARING AND PERIPHERAL CYANOSIS CENTRAL CYANOSIS More severe Lips, nose, ears, neck region, tongue Darker pigmentation more difficult to see ACROCYANOSIS ACROCYANOSIS PURSED-LIP BREATHING Commonly seen in patient’s with COPD Technique taught to patients Pucker lips during exhalation EYES http://tbn0.google.com/images?q=tbn:q46FZ9kJXZireM:http://upload.wikimedia.org/wikipedia/commons/thumb Evaluated as part of mydriasis the neurologic exam PERRLA Mydriasis dilated and fixed miosis Miosis pinpoint pupils EYES Ptosis: drooping upper lid Diplopia: double vision Nystagmus NECK Inspection and palpation used to determine: tracheal position JVP (jugular venous pressure) Accessory muscle use Tracheal shift Away from affected side Tension pneumothorax, pleural effusion, To affected side Atelectasis, lung resection PNEUMOTHORAX JVP Estimated by examining the level of the column of blood in the jugular veins Jugular Veins are full in a supine position At a 45º angle, the column of blood descends to few cm above clavicle Measure the distance veins are distended above sternal angle  Changes with breathing Most common cause is right heart failure Other causes: Hypervolemia Obstruction of venous return to the R atrium JVP LUNG TOPOGRAPHY ANTERIOR Midsternal line Midclavicular lines Midaxillary line Anterior axillary line IMAGINARY Posterior axillary line LINES POSTERIOR Midspinal line Midscapular lines THORACIC CAGE LANDMARKS  Suprasternal notch  Sternal angle or angle of Louis  Ribs SUPRASTERNAL NOTCH THORACIC CAGE LANDMARKS POSTERIOR  Spinous processes of vertebrae  Most prominent spinous process at the base of the neck  C7 spinous process  Scapular borders. LUNG FISSURES Interlobar fissures: Oblique fissure Right and left lung Horizontal fissure Right lung LUNG FISSURES LUNG FISSURES  Tracheal Bifurcation: Carina Approximately T4 Diaphragm LANDMARKS Right dome Anterior: 5th rib Posterior: T9 Left dome Anterior: 6th rib Posterior: T10 TRACHEAL BIFURCATION (CARINA) Anterior chest: beneath the sternal angle Posterior chest: T4 TRACHEAL BIFURCATION Tracheal Bifurcation DIAPHRAGM At end-exhalation:  R dome is at:  5th rib anteriorly  T9 posteriorly  L dome is at:  6th rib anteriorly  T10 posteriorly.
