Crackles are the clicking, rattling, or crackling noises that may be made by one or both lungs of a human with a respiratory disease during inhalation, and occasionally during exhalation. They are usually heard only with a stethoscope ("on auscultation ").
SIPE is estimated to occur in 1-2% of competitive open-water swimmers, with 1.4% of triathletes, [2] 1.8% of combat swimmers and 1.1% of divers and swimmers [4] reported in the literature. Fatal cases can be mistaken for drowning because in both SIPE and drowning the lungs are heavy and filled with fluid, so post mortem findings may be similar.
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.

Chest X-ray has been used for many years to diagnose pulmonary edema due to its wide availability and relatively cheap cost. [4] A chest X-ray will show fluid in the alveolar walls, Kerley B lines , increased vascular shadowing in a classical batwing peri- hilum pattern, upper lobe diversion (biased blood flow to the superior parts instead of ...
The internal surface of the lungs on average in a non-emphysemic person is normally 63m2 and can hold about 5lts of air volume. [8] Both lungs together have the same amount of surface area as half of a tennis court. Disease such as, emphysema, tuberculosis, can reduce the amount of surface area and elasticity of the lungs.
Chest tubes are required in PSPs that have not responded to needle aspiration, in large SSPs (>50%), and in cases of tension pneumothorax. They are connected to a one-way valve system that allows air to escape, but not to re-enter, the chest. This may include a bottle with water that functions like a water seal, or a Heimlich valve.
Despite its promises, it has not been proven for screening or diagnosing diseases of the lung and other conditions, yet. It has long been appreciated that the exhaled breath is saturated by water vapour (e.g. by wind musical instrument players), but using it for studies of the lung was probably first described in the Russian scientific ...
