폐음 청진 Lung sound 대략 정리

Absent or decreased sounds can mean:

• Air or fluid in or around the lungs (such as pneumonia, heart failure, and pleural effusion)
• Increased thickness of the chest wall
• Over-inflation of a part of the lungs (emphysema can cause this)
• Reduced airflow to part of the lungs

 

There are several types of abnormal breath sounds. The four most common are:

• Rales. Small clicking, bubbling, or rattling sounds in the lungs. They are heard when a person breathes in (inhales). They are believed to occur when air opens closed air spaces. Rales can be further described as moist, dry, fine, and course. - Conditions associated with the presence of rales include pneumonia, atelectasis (a condition that causes the alveoli to become collapsed in certain areas of the lungs), fibrosis of the lungs, and heart failure.

 

• Rhonchi(건성 수포음). Sounds that resemble snoring. They occur when air is blocked or air flow becomes rough through the large airways. - 기도 안에 가래, 혈액 등과 같은 이물질로 인해 호흡을 함에 따라 기도벽으로부터 떨어지거나 움직여서 생기는 소리를 말합니다. 폐결핵, 폐렴, 기관지염, 천식 등이 있을 때 건성수포음이 들릴 수 있습니다.

 

• Stridor(천명). Wheeze-like sound heard when a person breathes. Usually it is due to a blockage of airflow in the windpipe (trachea) or in the back of the throat. - 천명은 기관지가 좁아지는 여러 호흡기 질환으로 인해 나타납니다. 그 대표적인 질환은 기관지 천식입니다. 그 외 천명을 유발하는 다른 질환으로 급성 및 만성 기관지염, 기관지 확장증, 세기관지염, 울혈성 심부전, 폐색전증 등이 있습니다.

 

• Wheezing. High-pitched sounds produced by narrowed airways. They are most often heard when a person breathes out (exhales). Wheezing and other abnormal sounds can sometimes be heard without a stethoscope.
