Lung Sounds on Percussion and Auscultation
https://michael.gradmedic.org/medicine/lungsound.pdf
So for percussion, any air filled cavity will sound resonant (pneumothorax, normal lung). The normal lung is less resonant than a pneumothorax as the lung tissue dampens the resonance slightly. Consolidated lung lacks the gas-filled space to resonate, and the liquid/gas boundary at an effusion prevents the impulse transmitting to the lung effectively. Normal breathing causes …

Metallic percussion sound: tympanic sound resembling a stroke on a metal may be heard over a large (6-8 cm in diameter) air-filled bulla in the lungs. Cracked-pot percussion sound (soft, resembles that of a cracked pot) may be heard over a large superficial cavity communicated with the bronchus through the narrow slit. Topographic percussion of the lungs

Tidal Percussion. Percuss down the back until the normal hyperresonance of the lungs becomes dull over the diaphragm. Then simply have the patient breath in and out deeply while continuing to percuss. The sound should wax and wane. Loss of tidal percussion: Pleural effusion; Hyperinflation such as emphysema from a maximally contracted diaphragm

Abstract. There are three percussion sounds, which are easily distinguishable by objective measures: tympany (heard with percussion over the intestines), resonance (heard over the normal lung), and dullness (heard over the liver or thigh). The percussion sound that is produced reflects the ease with which the body wall vibrates, which in turn is influenced by many variables, …

Hyperresonant sounds may also be heard when percussing lungs hyperinflated with air, such as may occur in patients with COPD, or patients having an acute asthmatic attack. An area of hyperresonance on one side of the chest may indicate a pneumothorax. Tympanic sounds are hollow, high, drumlike sounds. Tympany is normally heard over the stomach, but is not a …

Sound travels faster through solids than through air and liquid. Thus, breath sounds are louder with consolidation and lower decreased with pleural effusion, PTX, or emphysema. Percussion: Normal lungs are resonant. Too much air in the lungs [e.g. emphysema, asthma, PTX (unilateral), large air-filled bulla (unilateral)] makes the lung hyperresonant.

Percussion produces audible sounds which can be interpreted by a skilled examiner to discern fluid, air or solid material within the chest cavity . Technique [ edit | edit source ] Place your non-dominant middle and index fingers directly onto the patient’s skin, with your distal interphalangeal joints held firmly against the patient’s chest.
