Crackles are more common during the inspiratory than the expiratory phase of breathing, but they may be heard during the expiratory phase. Crackles are often described as fine, medium, and coarse. They can also be characterized as to their timing: fine crackles are usually late-inspiratory, whereas coarse crackles are early inspiratory.
Shortness of breath out of proportion to effort being expended. [2] [7] Rapid, heavy or uneven breathing, or uncontrollable coughing. [10] Crackles, rattling or ‘junky’ feelings deep in the chest associated with breathing effort – usually progressively worsening with increasing shortness of breath and may be cause for a panic attack [2] [7]
Dyspnea can come in many forms, but it is commonly known as shortness of breath or having difficulty breathing. People presenting with dyspnea usually show signs of rapid and shallow breathing, use of their respiratory accessory muscles, and may have underlying conditions causing the dyspnea, such as cardiac or pulmonary diseases. [ 5 ]
Other signs include end-inspiratory crackles (crackling sounds heard at the end of a deep breath) on auscultation and the presence of a third heart sound. [3] Shortness of breath can manifest as orthopnea (inability to breathe sufficiently when lying down flat) and/or paroxysmal nocturnal dyspnea (episodes of severe sudden breathlessness at ...
Crackles or wheeze are typical findings on listening to the chest with a stethoscope. Wheezes can occasionally be heard without a stethoscope. The child may also experience apnea, or brief pauses in breathing, but this can occur due to many conditions that are not just bronchiolitis. After the acute illness, it is common for the airways to ...
Dyspnea (painful breathing or difficulty breathing) is commonly seen, [6] and tolerance for exercise may be lowered. [7] Rapid breathing and a rapid heart rate are other signs. [ 8 ] [ 9 ] With more severe contusions, breath sounds heard through a stethoscope may be decreased, or rales (an abnormal crackling sound in the chest accompanying ...
On physical exam, increased breathing rates, increased heart rates, and a low-grade fever 38.5 o C (101.3 o F) are common. [9] [3] Listening to the lungs may reveal crackles in one or both lungs, often starting in the right middle lobe.
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]
