A palpable vibration felt on the chest wall, specifically during the assessment of the lungs by palpation while the patient speaks or coughs
Normal Percussion of Tone:
Resonant
Dull
Flat
Typanitic
Bronchial Sound
Normal sound of trachea
Normally heard over the trachea in the anterior chest and the second intercoastal
Vesicular sounds
Normal lung sound
Bronchovesicular sound
Normal, medium-pitched sound heard during both inspiration and expiration
Excursion
Should be equal bilaterally and measure 3-5cm in adults
Fine crackles
High pitched, short popping sound heard during inspiration and not cleared with coughing
Air passages that are coated with sticky with exudates
Associated with crackles
Pneumonia and Congestive Heart failure
Crackles occuring late in inspiration are associated with restrictive diseases such as:
Crackles occuring early in inspiration are associated with obstructive disorders such as:
Bronchitis
Asthma
Emphysema
Coarse crackles
Low pitched bubbling, moist sounds that may persist from early inspiration to early expiration; also described as softly seperating velcro
Inhales air comes into contact with secretions in the large bronchi and trachea
Associated with Pneumonia, pulmonary edema, fibrosis, COPD
Pleural friction rub
Low pitched dry, dry grating sound; sound is much like crackles, only more superficial and occuring during both inspiration and expiration
Rubbing of two inflamed pleural surfaces
Associated with pleuritis
Wheeze (sibilant)
High, pitched musical sounds heard primarily during expiration but may also be heard on inspiration
Air passes through constricted passages (caused by swelling secretions, or tumor)
Sibilant wheezing
Are often heard in cases of acute asthma or chronic emphysema
Wheezes (Snorous)
Low pitches snoring or moaning sounds heard primarily during expiration but maybe heard throughout the respiratory cycle. These wheezes may clear with coughing
Snorous wheezes
Are often heard in cases of bronchitis or single obstruction and snoring before an episode of sleep apnea
Stridor
Is a harsh honking wheeze with sever bloncholaryngospasm, such as occurs with croup
Bronchopony
Ask the client to repeat the phrase "99"
Egophony
Ask the client to repeat the letter "E"
Whispered petriloquy
Ask the client to whisper phrase "1-2-3"
Funnel chest
Pectus Excavatum
Pigeon chest
Pectus carinatum
Scoliosis
Lateral deviation of spine
Deep palpation
Could lead to displacement of the bone fragment against the lungs
Full and symmetric chest expansion (normally the thumbs should seperate 3-5cm during deep inspiration)
Ask the client to repeat word such as "Blue moon" or " 1-2-3"
In palpating the thoracic expansion palpate the chest for vocal (Tactile fremitus)
Percuss for diaphgramatic excursion
In percussing the thorax
In thoracic percussion, it penetrates to a depth of 5-7cm (2-3in), it detects superficial rather than deep lesions
Percussion sounds:
Flat
Dull
Resonant
Hyper resonant
Tympanic
Flat
Sound produced by very dense tissue
Dull
Thud like sound produced by dense tissue
Resonant
Hallow sound produced by lungs filled with air
Hyper Resonant
Described as booming sound
Tympanic
Drum like sound produced from air filled stomach
Lowest point of resonance is at the diaphragm
Percussion on a rib normally elicits dullness
Vesicular
Soft, low pitched sighing sounds created by air moving through the bronchioles and alveoli heard over lung periphery
Bronchovesicular
Moderate intensity "Blowing sound created by air passing through the bronchi heard between the scapula and lateral sternum
Bronchial
Loud and high pitched sound created by air passing through the trachea
Rhonchi (gurgles)
Loud low pitched, coarse sounds heard most often during inspiration and expiration
