![]() ![]() ![]() Palpation should focus on detecting abnormalities like masses or bony crepitus. Thoracic spine abnormalities such as kyphosis and scoliosis could also be noted during physical examination of the chest. Barrel chest could also be present which consists in increased anterior-posterior diameter of the chest wall and is a normal finding in children, but it is suggestive of hyperinflation with chronic obstructive pulmonary disease (COPD) in adults. Pectus carinatum is the exact opposite of pectus excavatum: in this anatomical abnormality, the sternum is protruding from the chest wall. The most common chest osseous abnormality is pectus excavatum where the sternum is depressed in to the chest cavity. Skeletal chest abnormalities should also be noted during the inspection. The position of the patient should also be noted, patients with extreme pulmonary dysfunction will often sit up-right, and in distress, they assume the tripod position (leaning forward, resting their hands on their knees).īreathing through pursed lips, often seen in cases of emphysema.Ībility to speak: patients that are unable to speak or become short of breath during the interview are likely to have a worse pulmonary function or reserve. The body habitus of the patient could provide information regarding chest compliance, especially in the case of severely obese patients were chest mobility, and compliance are reduced due to added weight from adipose tissue. The use of accessory breathing muscles (i.e., scalenes, sternocleidomastoid muscle, intercostal muscles) could point to excessive breathing effort caused by pathologies. Lung sounds.During the inspection, the examiner should pay attention to the pattern of breathing: thoracic breathing, thoracoabdominal breathing, costal markings, and use of accessory breathing muscles.

They mainly occur during inhalation but can also happen during exhalation.Ĭrackles occur as a result of small airways suddenly snapping open. Coarse: Coarse crackles occur in the larger bronchi tubes and are loud, low pitched, and last longer than fine crackles.The bronchi branch off into smaller and smaller passageways, which eventually lead to air sacs called alveoli. Medium: These result from air bubbling through mucus in the small bronchi - two tubes that carry air from the trachea to the lungs.Fine crackles may occur more frequently during a breath than coarse crackles and only happen during inhalation. Fine: These occur in the small airways and are soft and high pitched.They can sound similar to bubbling, popping, or clicking noises. It is very loud, harsh, and high pitched.Ĭrackles, also known as rales, are intermittent sounds generally audible during inhalation. Normal tracheal breath sound: A doctor can hear this sound over the trachea.However, if a doctor hears a bronchial breath outside the trachea, it could indicate a health issue. The sound is loud, hollow, and high pitched. Bronchial breath sound: The bronchial breath sound is audible over the trachea as a person breathes out.It is also continuous, more intense, and high pitched during inhalation than exhalation. The sound is soft, low pitched, and rustling in quality. Vesicular breath sounds occur when air flows into and out of the lungs during breathing. Normal lung or vesicular breath sound: A doctor can hear this sound over most of the chest with a stethoscope, a device for listening to a person’s internal body sounds.Healthcare professionals classify them in the following ways: These factors can help them determine whether the sounds from the lungs are regular or not.īreath sounds can differ depending on where they occur in the respiratory system. When a doctor listens to a person’s lungs, they note the frequency, intensity, and quality of the sounds they hear. ![]()
