Pulmonary Flashcards
Lungs, fissures, lobes
Each lung is divided roughly in half by oblique fissure
R lung divided by horizontal minor fissure
R lung divided into upper, middle, and lower lobes
L lung divided into upper and lower lobes
Trachea- bifurcated into mainstem bronchi at sternal angle and T4
Pleurae- serous membranes that cover surface of each lung (visceral pleura)
Inner rib cage and upper surface (parietal pleura)
Chest pain
Lung tissue does not have pain fibers. Pain in lung arises from inflammation of adjacent parietal pleura. Surrounding structures can irritate parietal pleura
SOB (dyspnea)
Non-painful, uncomfortable awareness inappropriate for level of exertion
“Have you had any difficulty breathing?” Determine severity based on patient’s daily activities
Wheezing musical respiratory sounds may be audible to patient and others
Cough- reflex response to stimuli that irritate receptors in larynx. Can have cardio origin
Hemoptysis***** TQ!!
Coughing up blood from lungs. Blood-streaked phlegm to frank blood. Like sputum. Can originate from mouth, pharynx, or GI tract
Pulmonary Examination
Inspect, Palpate, Percuss, and Auscultate
Vesicular** TQ!
soft and low pitches; usually heard over most of both lungs. Gentle rushing (normal lung sound)
Bronchial
Louder and higher in pitch. Tubular
- over manubrium
Bronchovesicular
Intermediate intensity and pitch; Rustling but tubular
- over 1st and 2nd interspaces and scapula on posterior
Tracheal
Very loud, very high pitch, very harsh
- over trachea in neck
Egophany, whispered pectoriloquey, and bronchophony are increased with
Consolidation - liquid instead of air
Lobes relation to chest wall
Anterior: RUL, RML, LUL, LLL
Posterior: lLUL, LLL, RUL, RLL (not right middle)
Lateral: RUL, RML, RLL, LUL, LLL (all)
Trachea’s position
Bifurcates into mainstem bronchi at sternal angle and T4, midline
Pectus excavatum
Funnel chest, depression in lower part of sternum. Compression of heart or vessel cause murmurs
Barrel chest
Increase AP diameter. Accompanies aging and COPD
Dyspnea
SOB
Diagnostic meaning of abnormal tactile fremitus
Fremitus decrease/absent when voice is soft, or transmission of vibrations is blocked
Causes- thick chest wall, blocked bronchus, COPD, pleural effusion, fibrosis, air, tumor
Asymmetric decreased fremitus-unilateral pleural effusion, pneumothorax.
Asymmetric increased fremitus- unilateral pneumonia.
