Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds. [2]
Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation , an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding ...
When auscultating the heart, doctors listen for abnormal sounds, including heart murmurs, gallops, and other extra sounds coinciding with heartbeats. Heart rate is also noted. When listening to lungs, breath sounds such as wheezes, crepitations and crackles are identified. The gastrointestinal system is auscultated to note the presence of bowel ...
The anterior fields can also be auscultated from the front. [15] [16] An area of thinner musculature on the back where sounds may be more audible is called the triangle of auscultation. [17] During auscultation, deep breaths are taken through the mouth and abnormal sounds listened for. [18] [19] Abnormal sounds include:
Heart murmurs are unique heart sounds produced when blood flows across a heart valve or blood vessel. [1] This occurs when turbulent blood flow creates a sound loud enough to hear with a stethoscope. [2] The sound differs from normal heart sounds by their characteristics. For example, heart murmurs may have a distinct pitch, duration and timing.
Understanding Lung Sounds 3rd edition (2002) by Steven Lehrer is a book and audio CD that guides the student through the skills of lung auscultation. It provides a complete overview of lung examination, anatomy, physiology, and pathology.
One should comment on S1 and S2 – if the splitting is abnormal or louder than usual. S3 – the emphasis and timing of the syllables in the word Kentucky is similar to the pattern of sounds in a precordial S3. S4 – the emphasis and timing of the syllables in the word Tennessee is similar to the pattern of sounds in a precordial S4.
A harsh murmur usually on left second intercostal space radiating to left neck and accompanied by palpable thrill. It can be distinguished from a VSD (ventricular septal defect) by listening to the S2, which is normal in VSD but it is widely split in pulmonary stenosis. However, VSD is almost always pansystolic where the murmur of pulmonary ...
