What Is Auscultation?

Auscultation is the use of ears or stethoscopes to detect the sounds that the body makes. Mostly used to listen to heart sounds, breathing sounds, etc. Commonly used stethoscopes have the function of sound collection and filtering. Through auscultation, medical personnel can diagnose the presence or absence of lesions in related organs according to the characteristics and changes of sound (such as the frequency of sound, strength, interval, noise, etc.).

Auscultation is a diagnostic method that uses hearing to determine whether it is normal based on the sounds made by various parts of the body.

Auscultation can be divided into two methods: direct auscultation and indirect auscultation.

1, direct auscultation (direct auscultation): the doctor directly attaches the ear to the body wall of the examinee for auscultation. The internal sound that can be heard by this method is very weak. this is

1. The auscultation environment should be quiet to avoid interference; warm and sheltered from the patient's additional sound due to muscle twitching.

2. Do not auscultate through clothing, the stethoscope body directly contacts the skin to get the exact auscultation result.

3 Patients should be instructed to take appropriate positions according to the condition and the need for auscultation.

4 Use the stethoscope properly. A stethoscope is usually composed of ear parts, body parts and hoses, and its length should be adapted to the length of the physician's arm. Before auscultation, pay attention to check whether the earpieces are in the correct direction and whether the hard tube and hose lumen are unobstructed. There are two types of body parts: bell type and membrane type. Bell type body parts are suitable for listening to low-key sounds, such as rumbling diastolic murmur of mitral valve stenosis. When using, touch the body surface to be inspected, but care should be taken to avoid the body Additional sounds caused by friction between the skin and the skin; membrane-type body parts are suitable for listening to high-profile sounds, such as murmurs of aortic valve insufficiency, breathing sounds, bowel sounds, etc., should be used in close contact with the body surface to be inspected.

5. Attention should be focused during auscultation, the interference of heart sounds should be eliminated when listening to the lungs, the interference of breathing sounds should be eliminated when listening to heart sounds, and patients should be instructed to control breathing and auscultation if necessary.
