Nursing 2220The Respiratory System Nursing Assessment (Auscultation) By Ginger VanDenBerg
Respiratory & AuscultationCourse Objectives • Discuss upper and lower respiratory anatomy • Discuss ventilation versus oxygenation • Identify nursing auscultation assessment of the respiratory system • Define assessment of normal versus abnormal respiratory sounds
Respiratory AnatomyOverview • Upper Respiratory System -Nasal Cavity -Oral Cavity -Pharnyx
Respiratory AnatomyOverview • Lower Respiratory System -Larnyx (Opening of the trachea) -Trachea (Windpipe) -Lungs (right/left) -Bronchus (divides into right/left) Upper & Lower Respiratory anatomy is consider to be the CONDUCTING portion No Gas Exchange Occurs
Respiratory Anatomy Overview • Terminal Bronchioles (<1mm diameter • Alveolar Ducts • Alveolar Sacs -Actual units of gaseous exchange in lungs Respiratory bronchioles to alveoli is consider to be the Respiratory Portion Gas Exchange does occur
POP Quiz • Structures of the upper airway include all of the following except? • Nasal Cavity • Oral Cavity • Pharnyx • Larnyx
Nursing Auscultation Assessment • Place the diaphragm of your stethoscope over the posterior chest between the ribs • Ask patient to take slow – deep breaths • Listen to an entire inspiration & expiration cycle at each position • Compare the sounds in one region to sounds in the same region on the opposite side • Anterior follows same pattern as posterior, with attention to the lower lobes for increased secretions
Normal Breath SoundsPosterior Thorax Posterior Thorax Sounds • Bronchovesicular– medium pitched blowing sounds, between the scapulae. Equal inspiratory & expiratory phases • Vesicular- heard over the lung periphery, smaller airways, soft & low pitched. Inspiratory phase is about 3x longer than expiratory phase
Normal Breath SoundsAnterior Thorax Anterior Thorax Sounds • Bronchovesicular & vesicular sounds-are heard above & below the clavicles and along the lung periphery • Bronchial-loud, high pitched, hollow sound, heard over the trachea, expiration last longer than inspiration
POP Quiz • During auscultation the nurse compares lung sounds on one side of the body to lung sounds in the same field on the opposite of the body? • True • False
Abnormal Breath Sounds(Adventitious) • Crackles-heard in dependent lobes, lung bases, sudden reinflation of alveoli. Bowl of rice krispies • Ronchi-heard over trachea & bronchi, caused by muscular spasm, fluid or mucus in larger airways, turbulent sound • Wheezes-heard over all lung fields, high-velocity airflow through narrow bronchus • Pleural friction rub-heard over anterior lung surface, parietal pleura rubbing against visceral pleura
Final POP Quiz • The following lungs sounds are considered to be advantitious except? • Crackles • Ronchi • Vescular • Wheezes
