Percussion (medicine) There are four types of percussion sounds: resonant, hyper-resonant, stony dull or dull. A dull sound indicates the presence of a solid mass under the surface. A more resonant sound indicates hollow, air-containing structures.

Also question is, what is resonance sound of the lungs?

Since lungs are mostly filled with air that we breathe in, percussion performed over most of the lung area produces a resonant sound, which is a low pitched, hollow sound. Therefore, any dullness or hyper-resonance is indicative of lung pathology, such as pleural effusion or pneumothorax, respectively.

Additionally, what are normal percussion sounds? There are three main medical percussion sounds: resonance (heard over lungs), tympany (heard over the air-filled bowel loops), and dullness (heard over fluid or solid organs).

Secondly, what causes Hyperresonant percussion?

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.

What is Aebe in respiratory system?

Auscultation of chest • Ask the patient to do deep breathing & put the stethascope on intercostal spaces • 1) If Intensity of sound is same on both sides ,it indicates equal air entry on both sides (AEBE = Air Entry Bilaterally equal ) – Mammary, Axillary • Supra scapular ,Inter scapular & Infra scapular • 2) By Type

What is resonance of voice?

Resonance refers to the amplification, richness and quality of your voice. Metaphorically, think of your mouth and throat as the speakers of your stereo system. This takes the load off your vocal folds. Resonant voice might be described as sounding "buzzy."

What is a simple definition of resonance?

In physics, resonance is the tendency of a system to vibrate with increasing amplitudes at some frequencies of excitation. These are known as the system's resonant frequencies (or resonance frequencies). The resonator may have a fundamental frequency and any number of harmonics.

What is Hyperresonance mean?

1. An extreme degree of resonance. 2. Resonance increased above the normal, and often of lower pitch, on percussion of an area of the body; occurs in the chest as a result of overinflation of the lung as in emphysema or pneumothorax and in the abdomen over distended bowel.

What does fluid in lung sound like?

Crackles are the sounds you will hear in a lung field that has fluid in the small airways. Coarse crackles sound like pouring water out of a bottle or like ripping open Velcro. This lung sound is often a sign of adult respiratory distress syndrome, early congestive heart failure, asthma, and pulmonary oedema.

What type of lung sounds are heard with pneumonia?

A pneumonia cough is generally a productive cough, often with yellow or green mucus. The breathing sounds are also different from asthma – Instead of wheezing, a doctor will hear rales and rhonchi with their stethoscope.

What are some examples of resonance?

Let's see the examples of resonance that occur in our everyday life.
  • Swing. A playground swing is one of the familiar examples of resonance.
  • Guitar. A guitar produces sound entirely by vibration.
  • Pendulum.
  • Singer Breaking A Wine Glass.
  • Bridge.
  • Music system playing on the high heavy beat.
  • Singing in shower.
  • Radio.

What are the 4 respiratory sounds?

The 4 most common are:
  • Rales. Small clicking, bubbling, or rattling sounds in the lungs. They are heard when a person breathes in (inhales).
  • Rhonchi. Sounds that resemble snoring.
  • Stridor. Wheeze-like sound heard when a person breathes.
  • Wheezing. High-pitched sounds produced by narrowed airways.

Why do we do percussion?

Percussion is a method of tapping body parts with fingers, hands, or small instruments as part of a physical examination. It is done to determine: The size, consistency, and borders of body organs. The presence or absence of fluid in body areas.

What is indirect percussion?

Indirect percussion is a technique which involves striking a punch-like object with a hammer or percussor. The tip of the punch is rested on the platform of the core at the point intended to receive the blow.

What is auscultation and percussion?

The Greek physician Hippocrates used auscultation (from the Latin for "listen") as a diagnostic technique. In percussion, the doctor taps parts of the patient's body with his or her fingers or with a hammer-like instrument called a "percussor".

Is tactile Fremitus normal?

Increased fremitus may indicate compression or consolidation of lung tissue, as occurs in pneumonia. Normal findings on palpation include: normal chest size and shape, tactile fremitus over the mainstem bronchi in front and between the scapulae in the back of the chest.

How do you do tidal percussion?

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.

What is tactile Fremitus?

Fremitus. In common medical usage, it usually refers to assessment of the lungs by either the vibration intensity felt on the chest wall (tactile fremitus) and/or heard by a stethoscope on the chest wall with certain spoken words (vocal fremitus), although there are several other types.

How did man use the percussion technique?

1 : the act of percussing: such as. a : the striking of a percussion cap so as to set off the charge in a firearm. b : the beating or striking of a musical instrument. c : the act or technique of tapping the surface of a body part to learn the condition of the parts beneath by the resultant

Where are Bronchovesicular sounds heard?

Bronchovesicular. Inspiration to expiration periods are equal. These are normal sounds in the mid-chest area or in the posterior chest between the scapula. They reflect a mixture of the pitch of the bronchial breath sounds heard near the trachea and the alveoli with the vesicular sound.

What is liver dullness?

Percussion During the Liver Exam
The purpose of liver percussion is to measure the liver size. Technique. Starting in the midclavicular line at about the 3rd intercostal space, lightly percuss and move down. Percuss inferiorly until dullness denotes the liver's upper border (usually at 5th intercostal space in MCL).

What does ascites sound like?

One technique for evaluating ascites is assessment of shifting dullness. In the ascitic abdomen, gas-filled bowel loops float to the top while the ascitic fluid falls to the dependent portion of the abdomen. As a result, percussion notes are tympanitic over the bowel loops and dull over the surrounding fluid.
