A breath sound that is not normally heard, such as a crackle, gurgle, rhonchus, or wheeze. It may be superimposed on normal breath sounds.
A small outpouching along the walls of the alveolar sacs through which gas exchange between alveolar air and pulmonary capillary blood takes place.
Angle of Luis
An anatomical landmark located on the sternum; it can be felt as a notch or ridge at the top of the sternum.
Anterior Axillary Line
An imaginary vertical line on the body wall continuing the line of the anterior axillary fold with the upper arm.
Base of Lungs
The base of the lung is broad and concave, rests on the convex surface of the diaphragm.
An abnormal respiratory pattern, characterized by short episodes of rapid, uniformly deep inspirations followed by 10 to 30 seconds of apnea.
Bronchial Breath Sound
A normal sound heard with a stethoscope over the main airways of the lungs, especially the trachea. Expiration and inspiration produce noise of equal loudness and duration, sounding like blowing through a hollow tube. The expiratory sound is heard during the greater part of expiration, whereas the inspiratory sound stops abruptly at the height of inspiration, with a pause before the sound of expiration is heard.
One of three normal breath sounds that occur between the sounds of the bronchial tubes and those of the alveoli, or a combination of the two sounds.
An abnormal pattern of respiration, characterized by alternating periods of apnea and deep, rapid breathing.
A form of breathing difficulty caused by an obstruction in the larynx, trachea, or bronchi. The patient attempts to compensate for this deficiency with prolonged, deep inspirations.
Coughing up of blood from the respiratory tract. Blood-streaked sputum often is present in minor upper respiratory infections or bronchitis.
Inadequate oxygen tension at the cellular level, characterized by tachycardia, hypertension, peripheral vasoconstriction, dizziness, and mental confusion.
An imaginary vertical line that passes midway between the anterior and posterior axillary folds.
(In anatomy) an imaginary line that extends downward over the trunk from the midpoint of the clavicle, dividing each side of the anterior chest into two parts.
An abnormal condition in which a person must sit or stand to breathe deeply or comfortably.
A congenital structural defect characterized by a prominent anterior projection of the xiphoid and the lower part of the sternum and by a lengthening of the costal cartilages.
Pleural Friction Rub
An abnormal coarse, grating sound heard on auscultation of the lungs during late inspiration and early expiration. It occurs when the visceral and parietal pleural surfaces rub against each other.
Posterior Axillary Line
Runs from the posterior axillary fold down the posterolateral aspect of the chest wall
Material coughed up from the lungs and expectorated through the mouth. It contains mucus, cellular debris, or microorganisms, and it also may contain blood or pus.
An abnormal high-pitched musical sound caused by an obstruction in the trachea or larynx. It is usually heard during inspiration.
Place hands on lower posterior chest wall with thumbs toward spine. Assess expansion of chest as thumbs move. Movement should be symettric
Vesicular Breath Sounds
A normal sound of rustling or swishing heard with a stethoscope over the lung periphery. It characteristically has a higher pitch during inspiration and fades rapidly during expiration.
