This can be particularly helpful in providing objective information when symptoms seem out of proportion to findings. Or when patients report few complaints yet seem to have a cosiderable amount of disease. It will also generate a measurement that you can refer back to during subsequent evaluations in order to determine if there has been any real change in functional status.

Detecting Chest Excursion. Assessing Fremitus. Effusions and infiltrates can perhaps be more easily understood using a sponge to represent the lung. In this model, an infiltrate is depicted by the blue coloration that has invaded the sponge itself sponge on left. An effusion is depicted by the blue fluid upon which the lung is floating sponge on right. Percussion Technique. Lung Auscultation. To start, instruct the patient to lean forward or sit upright in order to examine posteriorly.
Request the patient to place their hands on opposing shoulders to get maximum exposure to the lung fields. Place the diaphragm on the patient's mid-back area and ask them to take deep breaths in and out through their mouth. Auscultate at five levels posteriorly, and then repeat the same procedure anteriorly, comparing side-to-side.
Normal breath sounds should be symmetrical both posteriorly and anteriorly; any deviation is a possible indicator of a lung disease. The last three steps of auscultation are tests aiming to identify lung consolidation. First of these tests is to assess for bronchophony. Ask the patient to say "99", while auscultating the chest area. An increased sound transmission indicates a consolidated lung. Second is to assess for egophony. Ask the patient to say "E". When an "E" sound changes to an "A" through the stethoscope, it is an indication of a consolidated lung.
Lastly, assess for whispering pectoriloquy. Ask the patient to whisper "99". In case of a consolidated lung, the sound will actually be heard better and more clearly through the stethoscope.
All these steps should also be performed posteriorly at different locations in order to cover the entire lung area. At the end of the examination, thank the patient and have them change back.
You've just watched JoVE's video on percussion and auscultation for respiratory evaluation. Distinguishing between sounds heard during this portion of the exam can occasionally seem subjective, but the assessment becomes clearer and easier with practice, leading to a "spot diagnosis" for many pulmonary conditions. As always, thanks for watching!
Subscription Required. Please recommend JoVE to your librarian. Percussion and auscultation should always be done in sequence whenever performing a full respiratory examination.
Learning how to percuss correctly takes time and practice practice can be done on yourself or other surfaces, such as a table. Note how the percussion note changes naturally over air-filled lung, ribs, and solid organs, such as the heart. Auscultation must be performed over each lung zone to give the physician the best chance of identifying the focus of any lung pathology.
Abnormal breath sounds should be easily recognizable when occurring in a patient. Allow enough time to classify the breath sounds. Listen for several breathing cycles in one area, if necessary, to hear the exact nature of the crackles, wheezes, rhonchi, or other pathological findings. Distinguishing between certain breath sounds can occasionally seem subjective, but will become easier with practice, leading to a "spot diagnosis" for many pulmonary conditions.

Percussion allows your doctor to identify many heart-related issues based on the relative dullness of sounds. Conditions that can be identified using percussion include:. Your heart, lungs, and other organs in your abdomen can all be tested using auscultation and other similar methods. You might need additional tests for a diagnosis depending on the sounds your doctor hears.
Auscultation and related methods are a good way for your doctor to know whether or not you need close medical attention. Auscultation can be an excellent preventive measure against certain conditions.
Ask your doctor to perform these procedures whenever you have a physical exam. If you notice your stomach growling, there's most likely nothing wrong. But in rare instances, it could be a larger problem. Here's how to tell the…. Excess fluid in your lungs can cause bibasilar crackles. Learn more about the conditions that may cause this.
Abnormal breath sounds can indicate a lung problem, such as an obstruction, inflammation, or infection. Learn about breath sounds and what they may…. Learn the ins and outs of MRI vs. X-ray imaging tests, including the pros and cons of each test, how they compare to CT scans, how much they cost, and…. Paracentesis is a procedure to remove excess fluid from the abdominal cavity. Flat or extremely dull sounds are normally heard over solid areas such as bones. Dull or thudlike sounds are normally heard over dense areas such as the heart or liver.
Dullness replaces resonance when fluid or solid tissue replaces air-containing lung tissues, such as occurs with pneumonia, pleural effusions, or tumors. Hyperresonant sounds that are louder and lower pitched than resonant sounds are normally heard when percussing the chests of children and very thin adults. 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.
